I am trying load content via ajax when an <a> is clicked. The code I am using:
<script type="text/javascript">
jQuery(document).ready(function(){
// ajax pagination
jQuery('.znn_paginate a').live('click', function(){
var link = jQuery(this).attr('href');
jQuery('.lay1').html('<div class="zn_ajaxwrap"><div class="zn_ajax"></div></div>');
jQuery('.lay1').fadeOut("slow").load(link+' .post').fadeIn('slow');
});
}); // end ready function
</script>
The problem is When the content is loaded the page jumps to the top. I treid to prevent it with: e.preventDefault(); But then the the ajax loading stopped. I guess it stopped prevented the ajax loading too..
Is there any fix for this?
Thanks
P.S: I am using it on wordpress. Here is the tutorial I followed: http://seonix.org/wordpress-seo/easy-ajax-pagination/
EDIT
There was something wrong with the code. I am now using this without any problem: http://pastebin.com/vbXqmTHq
two things:
your function() should return false.
also the link itself should have href="javascript:void(0);

How can i load the jquery with rails. I have try in the following
<script src="jquery-1.7.1.min.js"></script>
<script src="jquery.masonry.min.js"></script>
<script>
$(function () {
var $container = $('#container');
$container.imagesLoaded(function () {
$container.masonry({
itemSelector: '.item'
});
});
});
</script>
But i am getting an error. This is included in my html code. Not in the header. Now I come to realize when clicking on it i get the error route not set up. How can i load it the proper way.
See application.js.
By default, jquery is part of rails starting from rails 3. You dont need to include it separately.
I am loading some code with the jQuery.ajax() method. In this code I want to have some jQuery-UI Widgets (sliders and calenders) but they won't appear in IE.
Here some example code where you maybe can help me to understand where I am going wrong.
The Code which will load the jQuery-UI Widgets
<script>
jQuery(document).ready(function(){
jQuery.ajax({
type:'post',
url: 'file.php',
success: function (data) {
jQuery('.somediv').empty().html(data);
}
});
});
</script>
The Code which is loaded and SHOULD initialize the jQuery-UI Widgets
<script>
jQuery(document).ready(function(){
jQuery('.datepicker-div').datepicker(someoptions);
jQuery('.slider-div').slider(someoptions);
});
</script>
<div class="datepicker-div">
<div class="slider-div">
You can see that it should be very simple. For FF it works fine but not for IE.
Maybe it has nothing to do with the document-ready statement?
Just call the initializers in the success event:
<script>
jQuery(document).ready(function(){
jQuery.ajax({
type:'post',
url: 'file.php',
success: function (data) {
jQuery('.somediv').empty().html(data);
jQuery('.datepicker-div').datepicker(someoptions);
jQuery('.slider-div').slider(someoptions);
}
});
});
</script>
Of course, you should refactor that by having a function for initializations:
function Initialize(){
jQuery('.datepicker-div').datepicker(someoptions);
jQuery('.slider-div').slider(someoptions);
}
Then have your success call it, as well as the ready() ebent:
<script>
jQuery(document).ready(function(){
jQuery.ajax({
type:'post',
url: 'file.php',
success: function (data) {
jQuery('.somediv').empty().html(data);
Initialize();
}
});
});
</script>
Update
I have read your question more carefully and now I fully understand it. Your ready() is in the loaded code. Then you should be using jQuery's load():
Script Execution
When calling .load() using a URL without a suffixed selector
expression, the content is passed to .html() prior to scripts being
removed. This executes the script blocks before they are discarded. If
.load() is called with a selector expression appended to the URL,
however, the scripts are stripped out prior to the DOM being updated,
and thus are not executed. An example of both cases can be seen below:
Here, any JavaScript loaded into #a as a part of the document will
successfully execute.
$('#a').load('article.html');
Try removing the scripts prior to appending the html, then adding them back.
var outHTML = data.replace(/<script>/ig,"<div class='script'>").replace(/<\/script>/ig,"</div>");
outHTML = $(outHTML);
var script = outHTML.find("div.script").detach();
$(".somediv").html(outHTML);
var s = document.createElement("script");
s.textContent = script.text();
document.body.appendChild(s);
Edit:
.find("div.script") may need to be changed to .filter("div.script") based on what your ajax request is returning.
Ok, I didn't found out how i can solve the Problem, but i found a work around.
The work around is very simple. Because in every browser except for the IE the loading of the script via ajax works fine, we have to identify the IE and change the behaviour to not loading the script but redirect to the site I wanted to load. I am doing this all in Joomla 2.5, so there was a bit work to do but basically it was the following code wich solved the problem.
// preparing the url
// check for ie
if (jQuery.browser.msie) {
window.location(url);
} else {
// do the ajax
}
I'm trying to load a google+ 1 button on a page, the goal is to have the buttons markup inserted into the page via ajax and then make the call for the button to be rendered.
The button renders fine when the page is loaded first time around. The problem arises when the markup is fetched from /displaycode.php and then the render call is made again.

<script type="text/javascript" src="https://apis.google.com/js/plusone.js">
{"parsetags": "explicit"}
</script>
<script type="text/javascript">
$(function() {
$("#btn").click(function() {
$('#live-preview').empty();
$("#live-preview").load('/displaycode.php #code');
gapi.plusone.go();
return false;
});
gapi.plusone.go();
});
</script>
<div id="live-preview"><div id="code"><div class="g-plusone"></div></div></div>
</div>
A demo of the problem can be viewed here http://32px.co/googleplusdemo.php . Thanks for any help in advance.
Render method
Use explicit render: https://developers.google.com/+/plugins/+1button/#example-explicit-render
gapi.plusone.render('live-preview')
instead of:
gapi.plusone.go();
Also needs "{"parsetags": "explicit"}" set:
<script type="text/javascript" src="https://apis.google.com/js/plusone.js">
{"parsetags": "explicit"}
</script>
Edit
You further have to make sure to call render after the jQuery load is complete. So the element is really in the DOM.
$(function() {
$("#btn").click(function(e) {
e.preventDefault();
$('#live-preview').empty(); // Not necessary
$("#live-preview").load('/displaycode.php #code', function() {
gapi.plusone.render('live-preview');
});
});
gapi.plusone.render('live-preview');
});
Could any one give an example, how to use Jquery in Controller Page. MVC3 -ASP.NET(How To put various tags like )
I want to show a simple alert before rendering a view in Controller.
Thank you.
Hari Gillala
Normally scripts are part of the views. Controllers shouldn't be tied to javascript. So inside a view you use the <script> tag where you put javascript. So for example if you wanted to show an alert just before rendering a view you could put the following in the <head> section of this view:
<script type="text/javascript">
alert('simple alert');
</script>
As far as jQuery is concerned, it usually is used to manipulate the DOM so you would wrap all DOM manipulation functions in a document.ready (unless you include this script tag at the end, just before closing the <body>):
<script type="text/javascript">
$(function() {
// ... put your jQuery code here
});
</script>
If you are talking about rendering partial views with AJAX that's another matter. You could have a link on some page that is pointing to a controller action:
#Html.ActionLink("click me", "someAction", null, new { id = "mylink" })
and a div container somewhere on the page:
<div id="result"></div>
Now you could unobtrusively AJAXify this link and inject the resulting HTML into the div:
$(function() {
$('#mylink').click(function() {
$('#result').load(this.href, function() {
alert('AJAX request finished => displaying results in the div');
});
return false;
});
});
EDIT: The problem is not related to Boxy, I've run into the same issue when I've used JQuery 's load method.
EDIT 2: When I take out link.remove() from inside the ajax callback and place it before ajax load, the problem is no more. Are there restrictions for manipulating elements inside an ajax callback function.
I am using JQuery with Boxy plugin.
When the 'Flag' link on the page is clicked, a Boxy modal pops-up and loads a form via ajax. When the user submits the form, the link (<a> tag) is removed and a new one is created from the ajax response. This mechanism works for, well, 3 times! After the 3rd, the callback function just does not remove/replace/append (tested several variations of manipulation) the element.
The only hint I have is that after the 3rd call, the parent of the link becomes non-selectable. However I can't make anything of this.
Sorry if this is a very trivial issue, I have no experience in client-side programming.
The relevant html is below:
<div class="flag-link">
<img class="flag-img" style="width: 16px; visibility: hidden;" src="/static/images/flag.png" alt=""/>
<a class="unflagged" href="/i/flag/showform/9/1/?next=/users/1/ozgurisil">Flag</a>
</div>
Here is the relevant js code:
$(document).ready(function() {
$('div.flag-link a.unflagged').live('click', function(e){
doFlag(e);
return false;
});
...
});
function doFlag(e) {
var link = $(e.target);
var url = link.attr('href');
Boxy.load(url, {title:'Inappropriate Content', unloadOnHide:true, cache:false, behaviours: function(r) {
$("#flag-form").live("submit", function(){
var post_url = $("#flag-form").attr('action');
boxy = Boxy.get(this);
boxy.hideAndUnload();
$.post(post_url, $("#flag-form").serialize(), function(data){
par = link.parent();
par.append(data);
alert (par.attr('class')); //BECOMES UNDEFINED AT THE 3RD CALL!!
par.children('img.flag-img').css('visibility', 'visible');
link.remove();
});
return false;
});
}});
}
Old and late reply, but.. I found this while googling for my answer, so.. :)
I think this is a problem with the "notmodified" error being thrown, because you return the same Ajax data.
It seems that this is happening even if the "ifModified" option is set to false (which is also the default).
Returning the same Ajax data three times will cause issues for me (jQuery 1.4). Making the data unique (just adding time/random number in the response) removes the problem.
I don't know if this is a browser (Firefox), jQuery or server (Apache) issue though..
I have had the same problem, I could not run javascript after I call boxy. So I put all my javascript code in afterShow:function one of boxy attributes. I can run almost except submit my form. My be my way can give you something.
