I have a jQuery script that dynamically changes select menus. The script uses the function populate() everytime a change event occurs in one of the menus. I would like the same script to run after a form submit. To have an idea this is what the script looks like...
$(document).ready(function(){
function getUrlVars() {
var vars = {};
var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
vars[key] = value;
});
return vars;
}
function populate() {
if ($('#STATEID').val() == 'AK' || $('#OB_USTATEID').val() == 'DC') {
// Alaska and District Columbia have no counties
$('#county_drop_down3').hide();
$('#no_county_drop_down3').show();
}
else {
fetch.doPost('../../getCounties2c.php');
}
}
$('#STATEID').change(populate);
var fetch = function() {
var counties = $('#countyid');
return {
doPost: function(src) {
$('#loading_county_drop_down3').show(); // Show the Loading...
$('#county_drop_down3').hide(); // Hide the drop down
$('#no_county_drop_down3').hide(); // Hide the "no counties" message (if it's the case)
if (src)
$.post(src, { state_code3: $('#STATEID').val() }, this.getCounties);
else
throw new Error('No SRC was passed to getCounties!');
},
getCounties: function(results) {
if (!results)
return;
var allCities = $("<option value=\"All\">All Counties</option>");
counties.html(results);
counties.prepend(allCities);
var first = getUrlVars()["countyid"];
if (first) {
counties.val(first).attr('selected',true);
}
else {
counties.val("All").attr('selected',true);
}
$('#loading_county_drop_down3').hide(); // Hide the Loading...
$('#county_drop_down3').show(); // Show the drop down
}
}
}();
populate();
});
How can I accomplish that? Any suggestions will be highly appreciated!
Use $(element).submit(function (e) {} ); to catch a submit event. You can even fire it off, by calling $(element).submit().

I have a function that on click add/removes stuff from a SQL database.
I do a condition to check if it is refering to an add or remove and execute the code.
the add function works perfectly, but the remove not and its the same code, am i missing something obvious? And is this the best way to do this?
jquery:
//add card from list
$("#listcards a").click(function() {
if($(this).attr('add').length > 1) {
var value = $(this).attr('add');
$.post('searchc.php',{add:value}, function(data){
$("#add_result").html(data);
});
return false;
}
});
//remove card from list
$("#listcards a").click(function() {
if($(this).attr('rem').length > 1) {
var value = $(this).attr('rem');
$.post('searchc.php',{rem:value}, function(data){
$("#add_result").html(data);
});
return false;
}
});
html code:
<form id="listcards" method="post">
<input type='hidden' id='lcard' name='lcard' value=''>
<div>
bla bla -> imagem no + ? ou por algum efeito css+ | -<br>
coiso coiso + | -<br>
</div>
</form>
Do i also need to be in a form for the POST or a div would work too?
You've got two click handlers for the same elements, which could be causing a problem. You don't need to run both sets of code for each <a> element. Instead give the elements a class to show exactly what they do, and then limit your selectors to those elements
HTML:
+ | <a href="" class="remove" rem="bla bla">
Script:
$("#listcards a.add").click(function() {
var value = $(this).attr('add');
$.post('searchc.php',{add:value}, function(data){
$("#add_result").html(data);
});
return false;
});
//remove card from list
$("#listcards a.remove").click(function() {
var value = $(this).attr('rem');
$.post('searchc.php',{rem:value}, function(data){
$("#add_result").html(data);
});
return false;
});
You can use it like thisi will give only remove functionality. And oif possible add ajax.
$("#listcards .rem").click(function() {
var value = $(this).text();
if($(this).length()>1) {
$.post('searchc.php',{rem:value}, function(data){
$("#add_result").html(data);
});
return false;
}});
Suppose you don't have any card when you're loading this page 1st time. Then you click add new & a new card get's added to your html.
Now for this newly added card, the "remove" method doesn't get bind as that was loaded on page load (when this new card element was not present). Hence your remove method is not working for newly added cards.
So to make it work, you need to bing the remove method on new cards too. You can do that by keeping you remove part in a js function which you would call in "add" part after putting new card into html.
function removeCard(){
// first unbind the click event for all cards if any & then bind it
$("#listcards a").off('click');
//remove card from list
$("#listcards a").click(function() {
if($(this).attr('rem').length > 1) {
var value = $(this).attr('rem');
$.post('searchc.php',{rem:value}, function(data){
$("#add_result").html(data);
});
return false;
}
});
}
And you add part should be like this:
//add card from list
$("#listcards a").click(function() {
if($(this).attr('add').length > 1) {
var value = $(this).attr('add');
$.post('searchc.php',{add:value}, function(data){
$("#add_result").html(data);
removeCard(); // adding remove method here
});
return false;
}
});
Follow up your code,
$("#listcards a").click(function() {
var action = $(this).attr("add") ? "add" : "rem";
var value;
if(action == "add")
value = $(this).attr('add');
if(action == "rem")
value = $(this).attr('rem');
var param = {};
param[action] = value;
$.post('searchc.php',param, function(data){
$("#add_result").html(data);
});
});
Use onclick function to do this
It can help you out
+
-<br>
function addthis(addthis) {
if(addthis.length > 1) {
alert(addthis);
// $.post('searchc.php',{add:addthis}, function(data){
// $("#add_result").html(data);
// });
return false;
}
}
function removethis(remthis) {
if(remthis.length > 1) {
alert(remthis);
// $.post('searchc.php',{reb:remthis}, function(data){
// $("#add_result").html(data);
// });
return false;
}
}
Below is the code which I use to upload images through dropzone.
<script>
Dropzone.options.uploaddeadlineimages = {
// The camelized version of the ID of the form element
// The configuration
paramName: 'files',
url:"<?=base_url()."Product/upload_listing_images";?>",
dictDefaultMessage: "<img src='<?=base_url()."public/images/";?>/frontend/camera-black.png'><h2>Drag and drop your photos here to upload</h2><p><a href='javascript:void(0)'>Or Click here to browse for photos</a></p>",
uploadMultiple: false,
createImageThumbnails: true,
addRemoveLinks: true,
parallelUploads:100,
dictInvalidFileType:'Please upload only valid file type(png,jpg,gif,pdf)',
clickable:true,
maxFiles:100,
autoProcessQueue: true,
success: function( file, response ) {
var return_value = response;
var old_value = $('#listing_images').val();
if(old_value=="" || old_value==" " || old_value==null){
var new_value = return_value;
}else{
var new_value = old_value+","+return_value;
}
$('#listing_images').val(new_value);
},
// The setting up of the dropzone
init: function() {
var myDropzone = this;
//alert after success
this.on('queuecomplete', function( file, resp ){
//alert('hahahahahaha');
});
// First change the button to actually tell Dropzone to process the queue.
document.getElementById("create_listing_button").addEventListener("click", function(e) {
// Make sure that the form isn't actually being sent.
});
// Listen to the sendingmultiple event. In this case, it's the sendingmultiple event instead
// of the sending event because uploadMultiple is set to true.
this.on("sendingmultiple", function() {
});
this.on("successmultiple", function(files, response) {
// Gets triggered when the files have successfully been sent.
// Redirect user or notify of success.
});
this.on("errormultiple", function(files, response) {
// Gets triggered when there was an error sending the files.
// Maybe show form again, and notify user of error
});
}
}
</script>
the code has this parth which is used to append the new filename into hidden field so that i can save those names in database then. but the problem is that when i click on delete button i need to delete the name of that file from the hidden field too. I am getting an encrypted name from the server.
success: function( file, response ) {
var return_value = response;
var old_value = $('#listing_images').val();
if(old_value=="" || old_value==" " || old_value==null){
var new_value = return_value;
}else{
var new_value = old_value+","+return_value;
}
$('#listing_images').val(new_value);
},
I don't need the exact code. I just need a method by which i can pass the new filename to a function when i click on delete button. this should not prevent the delete from doing it default function
well i found an answer . just update the success part according to your need. but as in my case i needed the image name as id of preview element. it will be done in this way.
success: function( file, response ) {
var return_value = response;
var old_value = $('#listing_images').val();
if(old_value=="" || old_value==" " || old_value==null){
var new_value = return_value;
file.previewElement.id = response;
}else{
file.previewElement.id = response;
var new_value = old_value+","+return_value;
}
$('#listing_images').val(new_value);
},
to change the value of list after delete button just add the following code in dropzone.js file(just the way i did it).
the code starts from line number 274. just change it from this
removeFileEvent = (function(_this) {
return function(e) {
e.preventDefault();
e.stopPropagation();
if (file.status === Dropzone.UPLOADING) {
return Dropzone.confirm(_this.options.dictCancelUploadConfirmation, function() {
return _this.removeFile(file);
});
} else {
if (_this.options.dictRemoveFileConfirmation) {
return Dropzone.confirm(_this.options.dictRemoveFileConfirmation, function() {
return _this.removeFile(file);
});
} else {
return _this.removeFile(file);
}
}
};
})(this);
_ref2 = file.previewElement.querySelectorAll("[data-dz-remove]");
_results = [];
for (_k = 0, _len2 = _ref2.length; _k < _len2; _k++) {
removeLink = _ref2[_k];
_results.push(removeLink.addEventListener("click", removeFileEvent));
}
return _results;
}
},
to this(just four lines added. do it carefully, otherwise you can mess up all)
removeFileEvent = (function(_this) {
return function(e) {
e.preventDefault();
e.stopPropagation();
if (file.status === Dropzone.UPLOADING) {
return Dropzone.confirm(_this.options.dictCancelUploadConfirmation, function() {
return _this.removeFile(file);
});
} else {
if (_this.options.dictRemoveFileConfirmation) {
return Dropzone.confirm(_this.options.dictRemoveFileConfirmation, function() {
var id = $(this).closest("div").prop("id");
update_img_list(id);
return _this.removeFile(file);
});
} else {
var id = $(this).closest("div").prop("id");
update_img_list(id);
return _this.removeFile(file);
}
}
};
})(this);
_ref2 = file.previewElement.querySelectorAll("[data-dz-remove]");
_results = [];
for (_k = 0, _len2 = _ref2.length; _k < _len2; _k++) {
removeLink = _ref2[_k];
_results.push(removeLink.addEventListener("click", removeFileEvent));
}
return _results;
}
},
add this function at the end of file change ('#listing_images') to ('#id_of_your_field_which_contains_the_list')
function update_img_list(id){
var list = $('#listing_images').val();
separator = ",";
var values = list.split(separator);
for(var i = 0 ; i < values.length ; i++) {
if(values[i] == id) {
values.splice(i, 1);
$('#listing_images').val(values.join(separator)) ;
}
}
return list;
}
So. I have a Form with a lot of checkboxes. Along with that I have a piece of javascript code that is supposed to save the state of every checkbox when the user presses submit. My short and irritating problem is two things.
Question: I want to save Checkbox state to cookie ONLY when I submit the form, right now it saves if I mark a checkbox and reload the page, without submitting. Im working with Javascript and Cookies, two things that Im quite new to. So Im very greatful for all help. Here is my code that I got from here:
function getStorage(key_prefix) {
if (window.localStorage) {
return {
set: function(id, data) {
localStorage.setItem(key_prefix+id, data);
},
get: function(id) {
return localStorage.getItem(key_prefix+id);
}
};
} else {
return {
set: function(id, data) {
document.cookie = key_prefix+id+'='+encodeURIComponent(data);
},
get: function(id, data) {
var cookies = document.cookie, parsed = {};
cookies.replace(/([^=]+)=([^;]*);?\s*/g, function(whole, key, value) {
parsed[key] = unescape(value);
});
return parsed[key_prefix+id];
}
};
}
}
jQuery(function($) {
var storedData = getStorage('com_mysite_checkboxes_');
$('div.check input:checkbox').bind('change',function(){
storedData.set(this.id, $(this).is(':checked')?'checked':'not');
}).each(function() {
var val = storedData.get(this.id);
if (val == 'checked') $(this).attr('checked', 'checked');
if (val == 'not') $(this).removeAttr('checked');
if (val == 'checked') $(this).attr('disabled','true');
if (val) $(this).trigger('change');
});
});
So I want to save to cookie only on submit basically.
Bind to the submit event of the form instead of the change event of all the checkboxes.
Try this in place of your second function:
jQuery(function($) {
// bind to the submit event of the form
$('#id-of-your-form').submit(function() {
// get storage
var storedData = getStorage('com_mysite_checkboxes_');
// save checkbox states to cookie
$('div.check input:checkbox').each(function() {
// for each checkbox, save the state in storage with this.id as the key
storedData.set(this.id, $(this).is(':checked')?'checked':'not');
});
});
});
jQuery(document).ready(function() {
// on load, restore the checked checkboxes
$('div.check input:checkbox').each(function() {
// get storage
var storedData = getStorage('com_mysite_checkboxes_');
// for each checkbox, load the state and check it if state is "checked"
var state = storedData.get(this.id);
if (state == 'checked') {
$(this).attr('checked', 'checked');
}
});
});
I'm receiving the following error on this line of code
select.up().appendChild(sw);
With error "SCRIPT438: Object doesn't support property or method 'up' "
This only happens in Internet Explorer... Chrome, Safari, and Firefox all run the code fine. I'm unable to find anything via Google searching for "select.up()". This code isn't my own and I'm not very adept with using DOM in Javascript.

Appreciate any insight anyone could give me!
I'm pretty sure up() is a PrototypeJS method, so i'm pretty sure you would need it to work.
http://prototypejs.org/api/element/up
I m also facing this problem. so, i comment
var sw = new Element('div', {'class': 'swatches-container'});
$(select).up().appendChild(sw);
select.setStyle({position: 'absolute', top: '-9999px'})
lines from function create_swatches
and paste it in function trim(str).
After this i did not error again.
I have the following jquery code
$(document).ready(function() {
//Default Action
$("#playerList").verticaltabs({speed: 500,slideShow: false,activeIndex: <?=$tab;?>});
$("#responsecontainer").load("testing.php?chat=1");
var refreshId = setInterval(function() {
$("#responsecontainer").load('testing.php?chat=1');
}, 9000);
$("#responsecontainer2").load("testing.php?console=1");
var refreshId = setInterval(function() {
$("#responsecontainer2").load('testing.php?console=1');
}, 9000);
$('#chat_btn').click(function(event) {
event.preventDefault();
var say = jQuery('input[name="say"]').val()
if (say) {
jQuery.get('testing.php?action=chatsay', { say_input: say} );
jQuery('input[name="say"]').attr('value','')
} else {
alert('Please enter some text');
}
});
$('#console_btn').click(function(event) {
event.preventDefault();
var sayc = jQuery('input[name="sayc"]').val()
if (sayc) {
jQuery.get('testing.php?action=consolesay', { sayc_input: sayc} );
jQuery('input[name="sayc"]').attr('value','')
} else {
alert('Please enter some text');
}
});
$('#kick_btn').click(function(event) {
event.preventDefault();
var player_name = jQuery('input[name="player"]').val()
if (player_name) {
jQuery.get('testing.php?action=kick', { player_input: player_name} );
} else {
alert('Please enter some text');
}
});
});
Sample Form
<form id=\"kick_player\" action=\"\">
<input type=\"hidden\" name=\"player\" value=\"$pdata[name]\">
<input type=\"submit\" id=\"kick_btn\" value=\"Kick Player\"></form>
And the handler code
if ($_GET['action'] == 'chatsay') {
$name = USERNAME;
$chatsay = array($_GET['say_input'],$name);
$api->call("broadcastWithName",$chatsay);
die("type: ".$_GET['type']." ".$_GET['say_input']);
}
if ($_GET['action'] == 'consolesay') {
$consolesay = "§4[§f*§4]Broadcast: §f".$_GET['sayc_input'];
$say = array($consolesay);
$api->call("broadcast",$say);
die("type: ".$_GET['type']." ".$_GET['sayc_input']);
}
if ($_GET['action'] == 'kick') {
$kick = "kick ".$_GET['player_input'];
$kickarray = array($kick);
$api->call("runConsoleCommand", $kickarray);
die("type: ".$_GET['type']." ".$_GET['player_input']);
}
When I click the button, it reloads the page for starters, and isn't supposed to, it also isn't processing my handler code. I've been messing with this for what seems like hours and I'm sure it's something stupid.
What I'm trying to do is have a single button (0 visible form fields) fire an event. If I have to have these on a seperate file, I can, but for simplicity I have it all on the same file. The die command to stop rest of file from loading. What could I possibly overlooking?
I added more code.. the chat_btn and console_btn code all work, which kick is setup identically (using a hidden field rather than a text field). I cant place whats wrong on why its not working :(
use return false event.instead of preventDefault and put it at the end of the function
ie.
$(btn).click(function(event){
//code
return false;
});
And you should probably be using json_decode in your php since you are passing json to the php script, that way it will be an array.
Either your callback isn't being invoked at all, or the if condition is causing an error. If it was reaching either branch of the if, it wouldn't be reloading the page since both branches begin with event.prevntDefault().
If you're not seeing any errors in the console, it is likely that the callback isn't being bound at all. Are you using jQuery(document).ready( ... ) to bind your event handlers after the DOM is available for manipulation?
Some notes on style:
If both branches of the if contain identical code, move that code out of the if statement:
for form elements use .val() instead of .attr('value')
don't test against "" when you really want to test truthyness, just test the value:
jQuery(document).ready(function () {
jQuery('#kick_btn').click(function(event) {
event.preventDefault();
var player_name = jQuery('input[name="player"]').val()
if (player_name) {
jQuery.get('testing.php?action=kick', { player_input: player_name} );
} else {
alert('Please enter some text');
}
})
});
I figured out the problem. I have a while loop, and apparently, each btn name and input field name have to be unique even though they are all in thier own tags.
$("#playerList").delegate('[id^="kick_btn"]', "click", function(event) {
// get the current player number from the id of the clicked button
var num = this.id.replace("kick_btn", "");
var player_name = jQuery('input[name="player' + num + '"]').val();
jQuery.get('testing.php?action=kick', {
player_input: player_name
});
jQuery('input[name="player"]').attr('value','')
alert('Successfully kicked ' + player_name + '.');
});
