I have the following code
<html>
<head>
//included all jquery related stuff ..not shown here
</head>
<body>
<button id = 'btn' />
<div id = 'ct'>
<?php echo file_get_contents('my_ajax_stuff.php'); ?>
</div>
</body>
<script>
$('.datepicker').datepicker({dateFormat: "dd-mm-yy"});
$('#btn').click(function() {
$.ajax({
type: "GET",
url: "my_ajax_stuff.php" ,
success: function(response) {
$('#ct').html(response);
/*added following line to solve this issue ..but not worked*/
//$( ".datepicker" ).datepicker({dateFormat: "dd-mm-yy"});
} ,
error: function () {
$('#ct').html("Some problem fetching data.Please try again");
}
});
});
</script>
</html>
The page
my_ajax_stuff.php
contains a jquery ui datepicker with class = 'datepicker'.On the first load the datepicker works.But when I click on the button to reload it again , the contents are replaced with new contents.But the datepicker is not working.I have tried initialising the datepicker inside the ajax success handler ,as you see.But it also failed.What is the issue.How can it be solved???
You need to reinitialize the date picker in Ajax success
$('.datepicker').datepicker({dateFormat: "dd-mm-yy"});
$('#btn').click(function() {
$.ajax({
type: "GET",
url: "my_ajax_stuff.php" ,
success: function(response) {
$('#ct').html(response);
$( "#datepicker" ).datepicker();
/*added following line to solve this issue ..but not worked*/
//$( ".datepicker" ).datepicker({dateFormat: "dd-mm-yy"});
} ,
error: function () {
$('#ct').html("Some problem fetching data.Please try again");
}
});
});
The answer you are looking for may be similar to this question:
jQuery datepicker won't work on a AJAX added html element
You're replacing the datepicker element in the DOM with the ajax response.
The reason this works for the first time is that PHP renders the my_ajax_stuff.php on first load already in the HTML so it becomes available to jQuery in the DOM.
// do this once the DOM's available...
$(function(){
// this line will add an event handler to the selected inputs, both
// current and future, whenever they are clicked...
// this is delegation at work, and you can use any containing element
// you like - I just used the "body" tag for convenience...
$("body").on("click", ".datepicker", function(){
$(this).datepicker();
$(this).datepicker("show");
});
});
I came across this question because I was having the same problem as OP.
Mooed Farooqui's recommendation to reinitialize in Ajax success worked, but not initially.
Ended up that I was also calling the datepicker function in my equivalent of my_ajax_stuff.php. After I took that out it worked perfectly on button reload and postbacks. Hope this helps someone that stumbles upon this old question...
Call your picker inside .ajaxComplete function.
$(document).ready(function () {
// setup picker here...
});
$(document).ajaxComplete(function() {
// setup picker here...
});

This may be a primitive solution, but I found that If I have in my main document a function MakeDatePicker and I used it in the OnChange portion of my input, I was able to make any object, ajax, or otherwise, turn into a date picker before, and after an ajax call.
Here is the function and the call. (please note, I have ColdFusion # functions, as this is a return on a coldfusion query with a CFOutput.)
<td><input type="date" class="EstDeliveryDatePicker" chassis="#chassis#" value= "#DateFormat(EstDelivery,'mm/dd/yy')#" onclick="MakeDatePicker(this);"></input></td>
here is the function at the top of my page:
function MakeDatePicker(obj)
{
$(obj).datepicker({
changeMonth: true,
changeYear: true
});
$(obj).datepicker("show");
}
like I said, its crude, but it works.
I was having an issue with the way my tables would display their sorts. I have it so when you enter the page, you have 1 field that you can click on to select a date. If you click on one of the headers, it would sort SQL command, and re-display the table. This would break the .datepicker function. So I change it to not read off the class, but make the click, trigger the function. the problem with trying to get it to run on the .class was it would initialize after the table was redrawn and lose the scope of the DOM.

Entry level user here. I've seen countless AJAX\PHP examples with data being passed via POST or GET and modified one of their examples. When clicking the button (id="clickMe) I want it to execute advertise.php and nothing more (no variables need to be passed) without refreshing the page and a notification that says success. When I click the button with my current code nothing happens.
<button type="button" id="clickMe">CLICK ME TO RUN PHP</button>
<script type="text/javascript">
$(document).ready(function(){
$('#clickMe').click(function(event){ // capture the event
event.preventDefault(); // handle the event
$.ajax({
url: 'advertise.php',
data: {
'ajax': true
},
success: function(data) {
$('#data').text(data);
}
});
});
});
</script>
Updated, but still isn't executing.
Here is your editted version code:
$(document).ready(function(){
$('#clickMe').click(function(){
$.post("PHP_FILE.php",{ajax: true},function(data, status){
alert(data);
});
});
});
2 things - you need a document ready handler and to prevent the default click action.
$(document).ready(function() {
$('#clickMe').click(function(event){ // capture the event
event.preventDefault(); // handle the event
$.ajax({ // remainder of code...
});
When loading jQuery scripts at the top of the page you need to make sure they do not run until the DOM has loaded, that is what the document ready handler is for. The you capture the click event by including it as an argument for your click's callback function and handle the click with the preventDefault() method.
Since this request is "simple" you may want to consider using one of the shorthand methods, like $.post()
I've got a dynamic page which I'm loading from an external PHP file when the booking link is clicked.
My issue is the jQuery code I need to run straight after it sometimes tries to execute before the PHP page is fully loaded (the follow and remove parts specifically). So when I try load the div, jQuery works sometimes, and other times not.
From what I've seen on other examples $(document).ready(function() is supposed to prevent the jQuery executing until the page is fully loaded, however since I'm loading a specific div (content) and not the entire page it seems to not work?
$(document).ready(function(){
$(document).on('click', '.booking', function (){
$('#content').load('calendar.php');
$.getJSON(url,data, function(data) {
$.each(data, function(index, data) {
$("#blocksid"+data.slot_id).css("background-color","#009cd0");
$("#follow"+data.slot_id).hide();
$("#remove"+data.slot_id).show();
});
});
return false;
});
});
Thanks in advance for any assistance!
To achieve what you are expecting in a predicable way you should run dependent javascript code
after loading content to div. Just create a call-back function for load method and have your dependent code inside it.
$('#content').load("calendar.php", function() {
//put the code here, that you need to run after loading content to above div
});
You need to set:
$.ajaxSetup({ async: false });
and then turn it back on by:
$.ajaxSetup({ async: true });
or use
$.ajax({
async:false
});
I am doing a basic jquery ajax call on a php file and can't seemsto figure out why it isn't working. Any help is appreciated. Fiebug does not seem to show any ajax or XHR action going on. I want to not to refresh the page and just execute the ajax call. Thanks.
JS
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"</script>
<script>
function getData(url_param){
$.ajax({
type: 'get',
url: 'data.php',
data: {url_param:url_param},
success: function(data) {
$('#data').html(data);
}
});
};
$('#clickMe').click(function(e){
e.preventDefault();
getData(2);
});
</script>
HTML:
<div><a id='clickMe' href='data.php?url_param=url_param'>CLICK ME TO RUN PHP</a></div>
<div id="data"></div> <!-- divto show result -->
PHP:
<?php
if($_GET['url_param']){
echo "simple ajax call";
}
?>
You have to bind the event inside an onload function. The most common practice is:
$(document).ready(function(){
$('#clickMe').click(function(e){
...
});
});
You should also add return false; in the last line of your event.
First, you have misspelled your function name (getGata != getData).
Secondly:
data: {url_param:url_param}
Are you setting the javascript variable url_param anywhere? The $.ajax data parameter is formatted as follows:
get/post variable name : get/post variable value
As you have it now, it doesn't seem that you are assigning a value to url_param.
you can simply use jQuery post function.
$.post('data.php',{param1:'your param 1', param2 : 'your param 2'}, function(response){
//do your operation here. response is what you get from data.php. 'json' spicifies that the response is json type
$("#data").html(response);
},'json');
The (amended?) JavaScript prevents your code from working, because you haven't closed the angle brackets on jQuery source, it should be:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
One of the comments states you shouldn't have the href in the anchor, but because you've ignored defaults this isn't triggered (assuming JS is enabled in the user's browser).
Finally, I think that
return false;
should really be inside the function after
getData(2);
but since we're ignoring defaults, the anchor shouldn't make an attempt to go anywhere or reload anyway.
I'm trying to add a link to delete a row from a mysql database using jquery and ajax. The data is currently displayed in a table. For some reason, the Click event isn't triggering.
Here's my AJAX call:
<script>
$(document).ready(function() {
/* load table with page load*/
$("#sort tbody").load("inc/index_table.php");
/* row deletion */
$(".deletelink").click(function(){
var id = $(this).attr("id");
$.ajax({
beforeSend: function (request) {
var answer = confirm("Are you SURE you want to delete this?/nThis action is NOT reversible.")
if (answer){ return(true); }
else { return(false); }
},
type: "POST",
url: location.href,
data: "delete="+id,
error: function() {
console.log("Theres an error with AJAX deletion");
},
success: function(){ //a.td.tr.remove just that row rather than the whole table
$this.parent().parent().remove();
console.log("Deleted.");
}
});
});
});
</script>
And the relevant HTML:
this is part of a while loop that prints a table from my database:
<td><a class="deletelink" id="'.$row["id"].'"><img src="images/delete.png" alt="Delete"></a></td>';
My code specifies <a class="deletelink"> but it's not registering with $(".deletelink").click(function(){ });
Does anyone see what could be wrong here or have an alternate method to suggest?
Looks like you are loading the elements dynamically. You can only bind to elements which currently exist in the DOM. To bind to elements which you are about to add, you must attach the event to a static element, the closer it is to the dynamic content, the better.
Try using on() with a delegate.
$("#sort tbody").load("inc/index_table.php");
/* row deletion */
$("#sort tbody").on("click", ".deletelink", function(){
//...rest of code the same
});
on() was added in jQuery 1.7. If you are using a previous version, but higher than 1.4.2 you can use delegate() instead.
$("#sort tbody").load("inc/index_table.php");
$("#sort tbody").delegate(".deletelink", "click", function(){
//...rest of code the same
});
If #sort or tbody of $("#sort tbody") is also dynamic then $("document").on("click", "#sort tbody .deletelink", function(){...}) would work as well, though anything closer than document is better off course.
Edit
I'm just looking at your code again, the delegate binding should work, however, using load()'s success callback should work with your existing code too.
The callback is executed ones load has successfully completed. I'm not 100% certain but I'm assuming that when success is called that the elements already have been loaded into the DOM and as such the normal bindings should work.
If that doesn't work the dynamic bindings mentioned above should.
$("#sort tbody").load("inc/index_table.php", function(){
/* row deletion */
$(".deletelink").click(function(){
// .. your code as before.
});
});
to make sure the table is fully loaded, try to declare the click function, in the callback of .load() like,
$("#sort tbody").load("inc/index_table.php", function() {
/* row deletion */
$(".deletelink").click(function(){ ....
});
});
Try using .on() to bind the events to the elements
$(".deletelink").on('click',function(e){
e.preventDefault();
Also make sure to add preventDefault to stop the default functioning of the link
The problem is that your delete link appears after the table loads. So when page was loaded and DOM tree was built, it wasn't there. So you can't attach a click to it.
You can try live(). This can be used as
$(".deletelink").live('click',function(){
// ajax call handling code here
});
This function attaches event after the element has been introduced in the DOM. However, this function is a bit greedy as it keeps on scanning entire DOM tree on any DOM change. So use with caution
I am implementing the search functionality through ajax jquery, though I am new in this. I have done that by using keyup event. Whenever type something, according to that letter(s), my searching list has been coming. But thing is that, I am not getting any record when refresh the page. If I search something then only I am getting record and if in that position I delete all the texts typed over the search field, then the correct list of records are coming, but not initially.
$("#search_term").keyup(function(e){
e.preventDefault();
ajax_search();
});
function ajax_search(){
$("#search_results").show();
var search_val=$("#search_term").val();
$.post("user-account-other.php", {search_term : search_val}, function(data){
if (data.length>0){
$("#search_results").html(data);
}
})
}
<div id="search_results"></div>
Now please tell me how can solve this issue.
Put ajax_search() funcion in on onload of document and also on blur of a text box element then it will work perfectly
Im not 100% sure what you're asking. I'd be happy to update this answer with some more information once I can understand the problem. I did, however, want to show you how to better streamline your code.
See: http://api.jquery.com/load/
$("#search_term").keyup(function(e){
e.preventDefault();
ajax_search();
});
function ajax_search(){
var url = "user-account-other.php?search_term=" + $("#search_term").val();
$("#search_results").load(url, function(){
//Ajax Load is Done
}).show();
}
