Zeroclipboard and jQuery .load - php

so, I have a script like this
<script>
$(document).ready(function() {
$('#lista').load('gifs/1.php').fadeTo( "slow" , 1);
});
</script>
<script src="arqs/main.js"></script>
<ul id="lista"></ul>
main.js:
$(document).ready(function() {
var DOMarr=$('#lista li').map(function(){return this;});
var clip = new ZeroClipboard(DOMarr);
})
the problem is, zeroclipboard is not "injecting" the flash file when I use .load(), if I use php include it works normally but when I switch to load it does that :(
does someone knows a workaround?
I'll need to use load to switch the list, and I'd like zeroclipboard to allow copying from the new list

.load is an asychronous call so .ready may be executed before. Make sure the list is loaded before doing the ZeroClipboard call.

Change innerHTML from an external php file

I've got a script in an HTML file that runs a php file every 30 seconds. The php file is intended to change a div's innerHTML. I don't seem to find the way to replace it.
I was using load() but there are several divs I want to keep updating every 30 seconds and I don't want to make the server GET that much requests. So I'm looking for one only php get and then change the innerhtml in those several divs
This is what i've got:
HTML:
<script type="text/javascript">
$(document).ready(function () {
$.get('php.php');
});
setInterval(function(){
$.get('php.php');
}, 30000);
</script>
<div id="foo"></div>
php.php:
document.getElementById("foo").innerHTML = '<?php
// some php code
?>';
I think the problem is I'm not being able to get the element from the parent HTML file. I don't know how to solve this...
Any suggestions will be more than aprecciated!
You are reinventing jQuery's load()
function fetchContent() {
$("#foo").load('php.php');
window.setTimeout(fetchContent, 30000);
}
$(fetchContent);
The server should just return the HTML content that you want to display.
EDIT
Since your comment is different from the original question.
function fetchContent() {
$("#foo").get('php.php', function(data) {
var html = $("<div/>").html(data);
$("#foo").html( html.find("#Section1").html() );
$("#bar").html( html.find("#Section2").html() );
$("#asd").html( html.find("#Section3").html() );
window.setTimeout(fetchContent, 30000);
});
}
$(fetchContent);
You would want to add an onError handler and might want to set the no cache option for the Ajax calls.
what you probably want is for your php.php to return some data, and then you use the success of the $.get to update your #foo; taking an example from http://api.jquery.com/jQuery.get/ and modifying it for your example
$.get("php.php", function( data ) {
$( '#foo' ).html( data );
});
hope that helps :)

Javascript within AJAX loaded pages

I have a main (index) page which loads pages dynamically and places them inside it's div but the Javascript within those pages doesn't execute. Specifically this part
<script type="text/javascript">
$(document).ready(function(){
$('#regForm').submit(function(e) {
register();
e.preventDefault();
});
});
</script>
You will have to use getScript like this:
$('#foo').load('bar.html', function(){
$.getScript("js/fileName.js");
// call a function from fileName.js
});
You will have to put your JS code in that file and call that via getScript and then you can call functions from it as shown above.
Write your javascript in the index.php or write at the bottom of loaded page without document.ready
This is in reality a cross-browser issue: When <div>s are dynamically filled with HTML containing <script> tags, these scripts may or may not run - and this behaviour is different not only between browsers, but also between browser versions.
The only workaround I know of is to extract your JS, send it seperately and execute it after the <div> content has been set.

AJAX blocking Javascript

Consider the following code:
<script src="js/backgroundChanger.js" type="text/javascript"></script>
<script>
$(document).ready(function() {
$('.Themes').click(function(){
$('#dcontent').load('printThumbs.php');
});
});
</script>
The first script is for background changing logic and the second script gives list of thumbnails of the themes. The problem is that the first script doesn't work beacause of the second. If I don't use this AJAX technique everything works fine. Working code:
<script src="js/backgroundChanger.js" type="text/javascript"></script>
<div id="dcontent">
<?php include('printThumbs.php'); printThemesThumbs();?>
</div>
The background changing logic looks like:
$(function() {
$('.themes li a img').click(function() {//code
});
Any help will be greatly appreciated.
in your first snippet of the code you defined a click function on .Theme and in the third snippet of the code .theme, is this correct?, i mean both classes seems to be different try to use the same class name return by your php function.
You're calling $(document).ready() twice, as $() is an alias, and the second definition is overwriting the first. First you are setting the document ready callback to
function() {
$('.themes li a img').click(function() {//code
}
and then overwriting it with
function() {
$('.Themes').click(function(){
$('#dcontent').load('printThumbs.php');
});
}
you have to add your second code in a callback function. you can't bind something if it is not already in the dom. if you want to make changes to the printThumbs output you need to add a callback...
<script>
$(document).ready(function() {//this is also a callback function when document is ready
$('.Themes').click(function(){//this can be understand as a call back too... code is fired after a click
$('#dcontent').load('printThumbs.php',function(){/*your callback code here...this code will be fired after you've loaded printThumbs*/}
});
});
</script>
if you want to do some jquery or other client side stuff on the respons of an ajax call (html,xml, json or whatever) you have to specify a callback function. to make things less complicated you have to look at the callback function just as the on document ready function with the difference that the callback is applied to the respons of your ajax call. if the code is not in a callback function you can't manipulate the respons because it is not injected in the dom/it simply does not exists in your browser when the document is ready.

jQuery toggle() doesn't work inside included (using PHP) code.

I have the following code defined in order to hide certain elements of a list:
<script type="text/javascript">
$(document).ready(function(){
$("button").click(function(){
$(".done").toggle();
});
});
</script>
Basically, any < button > element being clicked will execute the toggle() function on any element with the "done" class. I know this works, because it works on some of my buttons. I have a page made up of several included files (using PHP include()). Usually, the javascript works in and out of these included files, but for some reason if I put a button inside one of them, it doesn't work - the function only works for buttons placed on the document where the script is defined. Is this always the case, or am I doing something wrong?
try using jQuery live function:
$("button").live('click', function(){
$(".done").toggle();
});
Try changing:
$("button").click(function(){
to:
$("button").live('click', function(){
This will make the event bind to any button, no matter when they are added. If you are using .live, then you don't need it inside a $(document).ready( block, as .live will add the event when the element is added.

jQuery, php and Ajax issue: Can't make dynamic link load dynamic content

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.
