Hello I have issue with my jquery code, because when I want to press any key to get query from database that is not working (it is not showing any alert). I think my ajax isn't working very well because I tried to copy other code and didn't work. I want to get data from database with my skills to choose in options
jQuery code
$(document).ready(function () {
$("#skills").click(function () {
alert("test")
});
});
<select class="select2bs4" multiple="multiple" name="ums[]" data-placeholder="Skills"
style="width: 100%;" id="skills">
</select>
And I want to do when I press any key then should show any result in multiple select but at beginning didn't show any alert yet.
I tried to do like "Select2 and Laravel: Ajax Autocomplete" from Laraget website and that wasn't working too
EDIT____
If it's only input with type 'text' it's working fine to show alert
Thank you in advance
Try this
$(document).ready(function () {
$("#skills").change(function () {
alert("test")
});
});
Select will not work with click but with change , but if you want change when you write in select like search bar , replace this :
$("#skills").click(function () {
alert("test")
});
to this if you want to get the change option :
$("#skills").on('change',function () {
alert("test")
});
or this if you want to handle user input :
$("#skills").on('keyup',function () {
alert("test")
});

I was wondering if there is an easy way to work with multiple select boxes in Laravel. I am trying to make a city box, if the city is selected, if want to load the next controller that shows the areas in the city. Would this even be possible for a form?
Thank you
Thank you, guys.
It was quite easy to make.
Never expected it to be this easy.
I did it by setting a route to a new controller and working with javascript.
To the people that would like to make this in the near future.
Below you can find an idea of code that I have used for Laravel;
Javascript
$(document).ready(function () {
$('#city').change(function () {
var city = $("#city option:selected").val();
$.ajax({
url: "https://anma-maching-dev.aska-ltd.jp/destinations",
data: {
"city" : city
},
success: function(result){
jQuery('.area').html('');
$( ".area" ).fadeIn("fast", function() {
$(".area").append(result);
});
}
});
});
});
I attached the output of the controller to a div class called area!
route
Route::get('/destinations', 'destinationsController#get_area');
strong text
public static function get_area()
{
// your query to select the next information for your textBox
}
Background
So I have a table that is populated by a form. Each row can be edited by hitting a edit button. The Edit button opens the form that is populated. I need to auto fill the autocomplete so that the user can see one of His selected course.
How I Cheated
I'm using PHP and Codeigniter server side and am dynamically creating my form based on database. The labels and values are all produced from the Database and populate my JQuery Auto complete (a.k.a datasource variable below). From my controller I'm passing my value to the model and getting the Label from the DB. From there I'm passing it to my view and to my AutoComplete and setting the input value equal to the found label.
I feel dirty having done it this way. The inefficiency of this burns my eyes.
My Goal
I want to use the value that I've gotten and have the autocomplete select it and display it's label client side.
OR
I need to just display the label in the box so the user knows it's not a blank field.
Both options need to allow the user to modify the autocomplete box.
Existing Code
My code for the input looks like this:
<div class="row-start span-2">
<label for="course_code">Course Code </label>
</div>
<div class="row-end span-2">
<input id="course_code">
</div>
My script for the autocomplete looks like this:
<script>
function search_course_code(){
var datasource = [{"value":"1","label":"AAF100 - DL"},{"value":"2","label":"AAF101 - DL+web"},.....];
var searchboxid = "#course_code";
var searchresultid = "#CRSEINVID";
$(searchboxid).autocomplete({
source:datasource,
focus: function( event, ui ) {
$( searchboxid ).val( ui.item.label );
return false;
},
select: function(event,ui){
var UIvalue = ui.item.value;
var UIlabel = ui.item.label;
console.log(UIvalue);
console.log(UIlabel);
$( searchboxid ).val( ui.item.label );
use_search("#search1","#CRSEINVID",UIvalue,UIlabel ); return false;
}
});
};
function use_search(show_select,result_id,uivalue,uilabel){
//loads value to field that takes it's value
$(result_id).val(uivalue);
//Display course below search box
course = "<span>"+uilabel+"</span>";
$(show_select).html(course );
//stops the value from being shown in the search box
return false;
};
$( document ).ready(function() {
search_course_code();
});
</script>
I draw the value from a hidden input with a unique ID simply using JQUERY val() function.
What I've tried
Try 1
Setting value using:
$(searchboxid).val(hiddenInputValue);
Result: Value displayed not the label
Try 2
Using the autocomplete on create method I tried to overwrite the UI object and send it to the select.
ui.item={"value":"","label":""};
ui.item.value=$(hiddenInputValue).val;
this.select(ui);
Result: No observable change, no errors.
Try 3
$(searchboxid).autocomplete("select", hiddenInputValue);
Result:
Uncaught Error: cannot call methods on autocomplete prior to
initialization; attempted to call method 'select'
Try 4
Tried changing value using
$(searchboxid).val(hiddenInputValue);
and having change function detect it and set label with
$( searchboxid ).val( ui.item.label );
Result: Value loaded into input not label
Try 5
Tried Triggering the change function with this:
$("#<?php echo $id;?>").autocomplete("option","change").call(searchBox);
and then setting label. Based on the answer to:
jQuery AutoComplete Trigger Change Event
Result: empty UI object for change function,
Try 6
Tried Triggering the select function with this:
$("#<?php echo $id;?>").autocomplete("option","select",{value:hiddenInputValue}).call(searchBox);
and then using my current select function.
Result: Uncaught Error: undefined is not a function,
Ideas
Ideas 1:
I thought of using the value then searching through the datasource object to find associating label and then using:
$(searchboxid).val(label);
would this work? How would I do it?
Idea 2:
If the value of the input field is set to a value using:
$(searchboxid).val(label);
Would the change function detect it? Not detected used console.log function in change function to give feedback,
So after much research and trying to get this to work I discovered two problems:
that I was using Select2 version 3.5.3 and needed to use text instead of label and :
$myselect.select2("val","somevalue");
The MAJOR source of my problem though was because I was using Web Experience Toolkit tabs and I needed to load the Select 2 after tabs where initialized.
assign the value to the auto complete input element by using
$('#YourAutoCompletBox').val(yourValuefromHiddenControl);
html:
Topic: <input type="text" id="topics" /><input type="hidden" id="topicID" />
<br/><br/><br/><br/>
<p>You selected <span id="results"></span></p>
jQuery:
var topics= [
{
value: "cooking",
label: "Cooking",
id: "1"
},
{
value: "C++",
label: "C++",
id: "2"
},
{
value: "craftsmanship",
label: "Software Craftsmanship",
id: "3"
}
];
$(document).ready(function() {
$( "#topics" ).autocomplete({
minLength: 0,
source: topics,
focus: function( event, ui ) {
$( "#topics" ).val( ui.item.label );
return false;
},
select: function( event, ui ) {
$( "#topics" ).val( ui.item.label );
$("#topicID").val(ui.item.id);
$( "#results").text($("#topicID").val());
return false;
}
})
});

I thought the easiest way would be to explain it with an image of what I have.
Summary -
I have a form to submit posts (pretty much like what you would find in twitter). Within each post there is an <ol> where comments to that post will reside.
Problem -
When I submit the first comment (button submit 2 in the picture), it doesn't call the ajax and just goes to a page where it presents me the php output of the comment. It seems it is not reloading or aplying DOM events to that portion of code. If I go back, the comment is presented (because it refreshs the page) and when adding the 2nd comment, everything goes normal, as expected. The problem is just the first comment.
Flow -
1) insert new post
2) click the textarea, put some text and press submit
3) Jumps to a page where php output for comment is presented
3a) no ajax call is done. It never enters the code
Could you please help me out understand what is going on? Thanks in advance.
In case you need more of the code just tell me.
JS (post_comment.js - associated with submit 2 in picture. I use ajaxForm - jquery form plugin - though I also tried with the standard .ajax call and the result is the same)
$(function () {
var options = {
success: function (html) {
var arrHTML = html.split(',');
var postId = $.trim(arrHTML[0]);
var html_code = arrHTML[1];
$('ol#post_comment_list' + postId).load(html_code);
//$('ol#post_comment_list'+postId 'li:first').slideDown('slow');
$('.footer-post').hide();
$('.comments-feed').delay(2000).slideUp({
duration: 1000,
queue: true
});
$('.small-textarea-main-feed').removeClass('set-large');
resetForm($('.footer-comment'));
},
error: function () {
alert('ERROR: unable to upload files');
},
complete: function () {
},
};
$(".footer-comment").ajaxForm(options);
function ShowRequest(formData, jqForm, options) {
var queryString = $.param(formData);
alert('BeforeSend method: \n\nAbout to submit: \n\n' + queryString);
return true;
}
function resetForm($form) {
$form.find('input:text, input:password, input:file, select, textarea').val('');
$form.find('input:radio, input:checkbox')
.removeAttr('checked').removeAttr('selected');
}
});
I am working on a site right now and have discovered that the jquery/javascript that I have implemented for the Search applies the same effect to all search boxes on the page when I click in the input field. By default, it removes the "Search" text and clears it out so that you can type your search term. I only want it to perform this function on the search box that is clicked within, not all search boxes on the page. However, if you look at this example, you'll notice that when you click into the search field at the top of the page, it clears the text out of both. I think I could fix it with .parent() or something, but am a jQuery novice. Any help would be appreciated.
Also don't know quite why the border is showing up around my icon, but I'll fix that.
Here's the search function jQuery:
$(document).ready(function(){
$('.search-box').textdefault({'text':'Search'});
});
(function($){
$.fn.textdefault = function(settings){
var Elements = this;
var settings = $.extend({}, $.fn.textdefault.defaults, settings);
return Elements.each(function(){
if($(Elements).is("input")){ TextDefault( $(Elements) ); }
});
function TextDefault(Input){
if (Input.val().length==0) Input.val(settings.text);
Input.focus(function () {
if (Input.val()==settings.text) Input.val('');
});
Input.blur(function () {
if (Input.val().length==0) Input.val(settings.text);
});
}
};
$.fn.textdefault.defaults = {
text: 'Search'
};
})(jQuery);
Thanks!

plugin example
here is the correction.
Elements contains all the elements that are 'passed' to this plugin.
var Elements = this;
By using $(Elements) instead of $(this) in the each function, you
used all inputs as one
return Elements.each(function() {
if ($(this).is("input")) {
TextDefault($(this));
}
});
This line of code should be called to initialize the plugin. So it should be put somewhere outside of the plugin, in a $(document).ready() {} code block for example, since you need the plugin initialized for the inputs on the load of the page.
$('.search-box').textdefault({
'text': 'Search'
});
Use a different selector. Instead of all inputs with a class of "search-box" try giving it a unique ID or class.
$("#search_default").textdefault({'text':'Search'});
or
$(".search-box.defaulttext").textdefault({'text':'Search'});
The HTML would then be
<input type="text" class="search-box defaulttext" ...
or
<input type="text" id="search_default" ...
This is the method that I use, which could also be helpful for you. It won't fire for both objects since it uses $(this) to control just the object being focused/blurred.
$(".search-box").live("focus", function(){
if ( $(this).val() == $(this).attr("rel") ){
$(this).val('');
}
}).live("blur", function(){
if ( $(this).val() == '' ) {
$(this).val( $(this).attr("rel") );
}
}).each( function(){
$(this).attr("rel", $(this).val() );
});
I would try to use a more "jQuery" way to do this. jsFiddle
$('input').focus(function(){
$(this).data('text', $(this).val()).val('');
});
$('input').blur(function(){
if( $(this).val() === "" ) $(this).val( $(this).data('text') );
});
i have forms createds that require a value , as this this forms edits different users.
so how would i send that value from jquery? i know how to do it with combobox , but i want to do it from links :
like - name [details] when someone clicks on details the forms will pop up, so i wana mimic index.php?id=2 but with jquery, anyideas?
Do you want to display some content via JQuery with a link? Modify the selector to point to the correct DOM object, eg. an anchor tag with class "details"
$('a .details').click(function ()
{
$.get(
'index.php?id=2',
function(html)
{
$('#results').html(html);
});
});
if you want to load the content the link is pointing to, use (untested)
$('a .details').click(function ()
{
var anchor = this;
$.get(
$(anchor).attr('href'),
function(html)
{
$('#results').html(html);
});
});
if the id is stored in the li element, you can get the "id" attribute by using:
$('li').attr('id');
$('a .details').click(function ()
{ $.get( 'index.php?id=2', <--------------I need to pass that id=2 from a link thats created dynamicaly.
function(html)
{ $('#results').html(html); });});
for example, using
a
<ul id="cat" >
</ul>
i can acces , "cat" through jquery, loop through the cat elements and each li id=
will be clickable with some css
I cant figure out how to do it with normal text links!
thanks anyway dspinozzi
