jQuery: how to trigger a click on document.ready only once? - hyperlink

I need to trigger a link, but only one time.
The problem is that the link loads the same page with some additional informations from a GET-function. So the page is in an endless reloading cycle.
This is my (dummy) code:
<a id="sendbutton" href="myurl.com/data1&data2">CLICK</a>
<script type="text/javascript">
$(document).ready(function(){
$('#sendbutton')[0].click();
});
</script>
PS: This is related to a cron job. This event only has to occur once a day.

You could verify the URL, and if it contains parameters, do not trigger the link.
<a id="sendbutton" href="myurl.com/data1&data2">CLICK</a>
<script type="text/javascript">
$(document).ready(function(){
if(location.pathname == "" ){
$('#sendbutton')[0].click();
}
});
</script>
I'm using the global variable "location" which store information about the current URL. Try this!

Overriding data-ajax="false" from parent container in jquerymobile

I am using the method noted here in the docs to set data-ajax="false" on a parent container for my site but I do have a few cases where I want the page to load via Ajax.
Is there a way to set the default on the parent container but allow individual links to override that setting? Adding data-ajax="true" to the individual links doesn't seem to work.
To set default for full page load:
$(document).on("mobileinit", function(){
$.mobile.ajaxEnabled = false;
});
To set individual, use data-ajax=true.
Somehow other suggestions didn't work for me. But this one did work. Tested.
This script disables all ajax links in the page jquery mobile - and those that should be ajax ones can be used as the a-link below with data-ajax=true.
<head>
<!-- ..... -->
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script>
$(document).on("mobileinit", function () {
// Reference: http://jquerymobile.com/demos/1.1.0/docs/api/globalconfig.html
$.extend($.mobile, {
linkBindingEnabled: false,
ajaxEnabled: false
});
});
</script>
<script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
<!-- ..... -->
</head>
<body>
<a href="holysmokewheredidtheajaxgo.html" data-ajax=true>Well, I'm still ajax. That's true!</a>
</body>

How do run javascript after loading PartialView in ASP.NET MVC?

I'm trying to get jQuery plug-in meioMask to work in a MVC Partial View.
As a trial, the following works:
<head>
<script type="text/javascript" src="jquery-1.8.3.min.js"></script>
<script type="text/javascript" src="jquery.meio.mask.min.js" charset="utf-8"></script>
<script type="text/javascript">
jQuery(function($) {
$('#StartTimeText').setMask('time');
});
</script>
</head>
<body>
<input type="text" id="StartTimeText" />
</body>
The text edit box gets a mask edit applied. However, my text edit box is in a MVC partial view that gets shown when user clicks on an item in the main view. In the main view's <head> I added the following:
<script src="#Url.Content("~/Scripts/jquery-1.8.3.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.meio.mask.min.js")" type="text/javascript"></script>
In CustomFormPartialView.cshtml, I have the following:
<script type="text/javascript">
jQuery.ajax(
function ($) {
$('#StartTimeText').setMask('time');
}
);
</script>
<input type="text" id="StartTimeText" />
But the text box remains a regular text box with no edit mask applied. I assume this is because the setMask function isn't getting run. I've tried using jQuery.get and jQuery.post as well, none of them made any difference.
Sorry if this has already been asked, I've tried other solutions without any luck. I'm a bit new in this area, so if someone can post as complete code example as possible it'll be greatly appreciated. Thanks.
EDIT:
Following JasCav's suggestion, I've put the following in the <head> section of the file. As far as I can tell, the ajax function isn't getting run at all. This is using DevExpress's MVC Scheduler if that's any help. I'm not getting any errors in FireBug.
<script type="text/javascript">
jQuery.ajax({
url: '/WebTMS_MVC/Calendar/SchedulerPartial',
type: 'POST',
success: function (data, textStatus, xhr) {
$('#StartTimeText').setMask('time');
}
});
</script>
You can use jQuery's ajax function provides a number of callbacks that you can use to perform specific actions after completion of the ajax call (success and complete are two). See more at jQuery's documentation for the ajax function.
$.ajax({
url: yourUrl,
type: "GET",
data: formData,
success: function(data) {
// Do your stuff here.
});

jquery mobile: when I second time visit the page the pagecreate event fired two times

I try to useing "live" to binding pagecreate event ,but when I second time visit the page pagecreate event fired two times.when I useing "bind" it is normal
<div data-role="page" name="logAddPage" id="logAddPage">
<script type="text/javascript">
$("#logAddPage").live("pagecreate",function (){
alert("pagecreate event fired ...");
});
</script>
</div>
It is better to remove any listeners before binding it.
$("#logAddPage").off("pagecreate");
$("#logAddPage").on("pagecreate", function (e) {
alert("pagecreate event fired ...");
});
i think you missed one bracket '('
try like this
<script type="text/javascript">
$("#logAddPage").live("pagecreate",function (){
alert("pagecreate event fired ...");
});
</script>

How to initialize pages in jquery mobile? pageinit not firing

What's the right way to initialize objects on a jquery mobile page? The events docs say to use "pageInit()" with no examples of that function, but give examples of binding to the "pageinit" method (note case difference). However, I don't see the event firing at all in this simple test page:
<html>
<body>
<script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript" charset="utf-8" src="http://code.jquery.com/mobile/1.0b3/jquery.mobile-1.0b3.min.js"></script>
<div data-role="page" id="myPage">
test
</div>
<script>
$("#myPage").live('pageinit',function() {
alert("This never happens");
});
</script>
</body>
</html>
What am I missing? I should add that if you change pageinit to another event like pagecreate this code works.
---- UPDATE ----
This bug is marked as "closed" in the JQM issue tracker. Apparently opinions differ about whether this is working properly or not.
It started working when I embedded script within page div:
<body>
<div id="indexPage" data-role="page">
<script type="text/javascript">
$("#indexPage").live('pageinit', function() {
// do something here...
});
</script>
</div>
</body>
Used jQuery Mobile 1.0RC1
.live() is deprecated, suggestion is to use .on() in jQuery 1.7+ :
<script type="text/javascript">
$(document).on('pageinit', '#indexPage', function(){
// code
});
</script>
Check the online doc for more information about .on(): http://api.jquery.com/on/
Turns out this is a bug in 1.0b3 that is fixed in the current head. So if you want a fix now, you gotta grab the latest from git. Or wait for the next release.
jQuery(document).live('pageinit',function(event){
centerHeaderDiv();
updateOrientation();
settingsMenu.init();
menu();
hideMenuPopupOnBodyClick();
})
This is working now. Now all page transitions and all JQM AJAX functionality would work along with your defined javascript functions! Enjoy!
pageinit will not fire in case it is on secondary pages ( NOT MAIN page ) if it is written in common <script> tag...
I have such a problem - on secondary pages that are not loaded with 'rel="external"', the code in the common <script> tag is never executed...
really this code is always executed...
<body>
<div id="indexPage" data-role="page">
<script type="text/javascript">
$("#indexPage").live('pageinit', function() {
// do something here...
});
</script>
</div>
</body>
althrough if you made "tabbed interface", using of "pageshow" is better
I had to put the script in the HTML page section which to me is a bug. It is loaded normally in a browser (not via AJAX) and all on a single page including javascript. We're not supposed to have to use document ready.
The easiest way I found to deal with this was to use JQM + Steal. It works like a charm as long as you put:
<script type='text/javascript' src='../steal/steal.js?mypage'></script>
Inside of the data-role='page' div.
Then use AJAX to connect anything that can use the same mypage.js and use an external link (by using the rel="external" tag) to anything that requires a different steal page.
#Wojciech BaƄcer
From the jQuery docs:
As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live().
Try this:
$('div.page').live('pageinit', function(e) {
console.log("Event Fired");
});
$(document).on("pageinit", "#myPage", function(event) {
alert("This page was just enhanced by jQuery Mobile!");
});
The events don't fire on the initial page, only on pages you load via Ajax. In the above case you can just:
<script>
$(document).ready(function() {
alert("This happens");
});
</script>

ruby on rails ajax update css on page

Does anyone know how I can update the style attribute of a division using an Ajax request?
For example, I have a division I inline style to display:hidden, and when a user clicks a link it changes the style to display:block
You don't need to perform an AJAX call to perform the above request. Plain old javascript will do. If you are using jQuery, try:
<div id="details">...</div
[Show]
<script type="text/javascript">
$("#toggle").click(function () {
$("#details").show();
});
</script>
For prototype, try:
<div id="details">...</div
[Show]
<script type="text/javascript">
Event.observe('toggle', 'click', function(event) {
$('details').show();
Event.stop(event);
});
</script>
