here is my fiddle of it all in action, but it wont display the content from the html file, it used to idk what I have done wrong?
It looks like you are using ASP.NET on the server. You can add the following line to your source pages:
Response.AppendHeader("Access-Control-Allow-Origin", "*");

BACKGROUND: I'm trying to use .load() to build a site from several
pages, where a user can click a button to load the next page's
content using .load().
PROBLEM: The .load() only works on the first click (loads
content from pagetwo.html), then doesn't load any
content for pages after that.
CODE:
My start page markup looks like this:
<head>
<script src="script.js"></script>
</head>
<body>
<div class="content">
<p>This is page 1.</p>
<button id="pageone">next</button>
</div>
</body>
Then my pages 2-5 contain only partial HTML, to be loaded
into div.content:
Page 2:
<p>This is page 2.</p>
<button id="pagetwo">next</button>
Page 3:
<p>This is page 3.</p>
<button id="pagethree">next</button>
Etc.
My jQuery script.js is loaded only once, with the full start page html:
$(document).ready(function() {
//load pages
$('button#pageone').click(function () {
$("div.content").load("page-two.html");
});
$('button#pagetwo').click(function () {
$("div.content").load("page-three.html");
});
$('button#pagethree').click(function () {
$("div.content").load("page-four.html");
});
});
Any ideas on why only the first .load() request works?
The ID #pagetwo and on onwards are newly introduced elements to the DOM after the first initial $(document).ready(). Thus, you'd have to access it differently there after:
$(document).on('click', 'button#pageone', function() {
$("div.content").load("page-two.html");
});
$(document).on('click', 'button#pagetwo', function() {
$("div.content").load("page-three.html");
});
$(document).on('click', 'button#pagethree', function() {
$("div.content").load("page-four.html");
});
The .on() handler will listen to any new elements through the entire document (As it starts at root) at any one stage. Your initial code was looking for elements that were present on just page load.
To read more about it, See the documentation about the .on() handler regarding new elements at "Direct and delegated events".
I am trying to retrieve information from a javascript file in my jQuery mobile website. Ajax is enabled by default, yet when I try xmlHttpRequest.send(), the responseText is the source code for the page rather than a json structure. The initialize() function is run at pageinit, so my thinking is that the json it is retrieving should exist when called. Also, initialize() works fine on the non-mobile variant of the site so I think it has something to do with how JQM handles ajax requests. Thanks in advance for any assistance.
<!DOCTYPE html>
<html>
<head>
var xmlHttpRequest;
var json;
<script type="text/javascript">
function initialize()
{
xmlHttpRequest = (window.XMLHttpRequest) ? new XMLHttpRequest() :
new ActiveXObject("Msxml2.XMLHTTP");
if (xmlHttpRequest == null)
return;
xmlHttpRequest.open("GET", "pick.js", false);
xmlHttpRequest.send();
json = eval('('+ xmlHttpRequest.responseText +')');
}
</script>
......
</head>
<body>
<div data-role="page" id="map-page">
<script type="text/javascript">
$('#map-page').live('pageinit',function(){
initialize();
});
</script>
.....
</div>
</body>
</html>
Since you're using jQuery Mobile (and thusly, jQuery), you should consider using jQuery.ajax -- it handles all of the 'hard stuff' like creating XHR object for you.
For your situation your code would look like this:
function initialize() {
$.get("pick.js", function(data, status, jqXHR) {
//when the call succeeds, do something with the 'data' param
console.log(data);
}, "script");
}
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.

return false;
});
gapi.plusone.go();
});

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');
});
I've an ajax code like this:
var req = new XMLHttpRequest();
req.open('GET', 'http://www.example.org/', false);
req.send(null);
if(req.status == 200)
var response = http_attendance.responseText;
document.getElementById('divAttendance').innerHTML = response;
When I get result on the page, FF browser shows the DOM elements on 'divAttendance'. If I want to put put some jquery effect on the result, I can't be able to do it.
DOM elements is clearly viewed using firebug. But, when I generate the source code of that page then there is no repsonse text on 'divAttendance'. It is blank like thisL:
<html>
....
..
<div id="divAttendance"></div>
..
..
</html>
How to manipulate or put some effect on that result ???
Well, if you are using jQuery then you should be using jquery ajax anyways
http://api.jquery.com/jQuery.ajax/
Regardless, if you are populating your div with AJAX response then it will not show up using "View Source" rather you will have to use a tool like firebug.
Your div initially should look like following
<div id="divAttendance" style="display:none"></div>
and your javascript should have the following
.....
document.getElementById('divAttendance').innerHTML = response;
$("#divAttendance").show("slow");
For such operations jQuery load is easy and usefull function, have a look at
http://api.jquery.com/load/
Your specific example can be rewritten as
<html>
....
IMPORT JQUERY.JS
<script language="javascript">
$('#divAttendance').load('http://www.example.org/', function() {
$("#divAttendance").show("slow");
});
</script>
..
<div id="divAttendance" style="display:none"></div>
..
..
</html>
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;
});
});
