Hello I'm doing this to add a string after a div in an html page with jquery:
Prepend items
<script type="text/javascript">
function PrependItemsToList()
{
$("#content_gallery").prepend($("<li></li>").text("prepend() item"));
}
</script>
Now I need to do it server side, any idea on how to implement it in php? I found phpquery but didn't find good docs about it.
So you're saying you want to do an AJAX call that returns HTML to be prepended to your content_gallery div?
<a class="prependLink" href="#">Prepend items</a>
<script type="text/javascript">
function PrependItemsToList()
{
var url="yourpage.php";
$.ajax(url, {
success: function(data, textStatus, jqXHR){
$("#content_gallery").prepend(data);
});
});
}
$('.prependLink').click(function(e){
PrependItemsToList();
e.preventDefault();
});
Of course, this approach is pointless if you aren't loading any information that isn't context-sensitive (ie. you pass some parameters to your remote page through your ajax call).
Posting more information will help us better answer your question.

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...
});
Here is a link
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.
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.
There's a great tutorial on IBM's website which walked me through a simple search/results list using jQuery,PHP and Ajax.
I was able to make it work and it's really cool.
One problem. I want the results to be hyperlinks and I can't get any java script to run on the results.
Here is the script I have (includes what was in the tutorial plus the additional script necessary to ovverride the hyperlink, click behavior):
<script type='text/javascript'>
$(document).ready(function(){
$("#search_results").slideUp();
$("#search_button").click(function(e){
e.preventDefault();
ajax_search();
});
$("#search_term").keyup(function(e){
e.preventDefault();
ajax_search();
});
$("a").click(ClickInterceptor);
});
function ajax_search(){
$("#search_results").show();
var search_val=$("#search_term").val();
$.post("./find.php", {search_term : search_val}, function(data){
if (data.length>0){
$("#search_results").html(data);
}
})
}
function ClickInterceptor(e)
{
window.alert("Hellow World!");
return false;
}
</script>
If i put the following html under the <body> tag:
this will work
That will display the alert window.
However, if I change the results to hyperlinks (found in find.php, listing 7 from the tutorial):
$string .= "".$row->name." - ";
It does not work.
Any idea on how to fix this?
The click function binds when it is run. You need to change it to a live binding.
$("a").live("click", ClickInterceptor);
Or you can just bind it when you update the search results by putting the following after $("#search_results").html(data):
$("#search_results a").click(ClickInterceptor);
The problem is pretty simple actually, $("a").click(ClickInterceptor); will only look for items that currently exist in the DOM. All you need to do is change that line to this:
$("a").live("click", ClickInterceptor);
I'd also advise taking the time to read more about jQuery's Events/live.
I found this great Tablesorter plugin for jQuery but I can't make it work with my PHP generated table. Here's the code:
<script type="text/javascript">
function table() {
$("#container").load("table.php?randval="+Math.random());
}
$(document).ready(function() {
table();
$("table").tablesorter();
});
</script>
Where #container is the div where the table will be and table is the name of the table. I get the table loaded but sorting function is not working.
It works if I put the table directly in html in the page.. but I don't see the point in having a static table for sorting.
Any help would be very appreciated.
$.load() performs a asynchronous request, i.e. the function does not wait for the data to arrive before returning. Therefore $("table").tablesorter(); is executed most likely before the table is added to the document. Either make it a synchronous call or (even better) pass a handler for the complete event to load.
http://api.jquery.com/load/:
.load( url, [ data ], [ complete(responseText, textStatus, XMLHttpRequest) ] )
url A string containing the URL to which the request is sent.
data A map or string that is sent to the server with the request.
complete(responseText, textStatus, XMLHttpRequest) A callback function that is executed when the request completes.
<script type="text/javascript">
$(document).ready(function() {
$("#container").load(
"table.php?randval="+Math.random(),
null,
function (responseText, textStatus, req) {
$("table").tablesorter();
}
);
});
</script>
