Note: JS/Jquery noob alert (yes, me)
There seems to be a conflict between the following two plugins:
TableSorter (2.9.1)
bootstrap-popover.js v2.2.1
The plugins work as they should separately, but when together, the popovers don't work. I've tried moving the calls to the popover script (and its initialization) before any other plugins, but no dice. I have a feeling the tablesorter script is somehow removing the titles from the DOM (another subject I know little about) before the popover script can load, but no dice.
In my HTML
<script src="../../js/jquery-1.8.2.min.js"></script>
<script src="../../js/jquery.tablesorter.js"></script>
<script src="../../js/jquery.tablesorter.pager.js"></script>
<script src="../../js/tooltips-popovers.js"></script>
<script>
$(function(){
$("#stats").tablesorter();
});
</script>
<script>
$("a[rel=popover]").popover({html:true,trigger:'hover'});
</script>
<script> /* Initiate pager */
$(function(){
var pagerOptions = {
container: $(".pager"),
};
$("table")
.tablesorterPager(pagerOptions);
});
</script>
Make sure you are initializing the popover script within a document ready event.
$(function(){
$("a[rel=popover]").popover({html:true,trigger:'hover'});
$("#stats")
.tablesorter()
.tablesorterPager({
container: $(".pager")
})
});
If that doesn't work, I can only guess that the popover links are inside the table? If so, they are added and removed dynamically, when sorting the table, so they might need to be added through a delegated event, the code above may not work in that case.
Update: As stated, the popup links are within the th, which I assume are in the thead? If so, try this code:
$(function(){
$("#stats")
.tablesorter({
initialized: function(table){
$("a[rel=popover]").popover({html:true,trigger:'hover'});
}
})
.tablesorterPager({
container: $(".pager")
})
});

I am using MVC to render a View.
The view has a single DIV element and a SCRIPT element.
The SCRIPT element has a simple alert('hello world').
When the view is rendered I expected to see the alert popup. Unfortunately this is NOT the case.
What can be done to invoke a script function after a View is rendered?
View.cshtml:
<div id="hello"></div>
<script type="text/javascript">
alert('Hello World!');
$('#hello').html('Hello world.');
</script>
* Updated *
My serious apologies. I found the issue. The problem was that within my script section I was setting an innerHTML without wrapping the string text with quotes. I guess this caused the browser to be confused and just silently crash. I found this out, by happenstance/luck, when I was looking at the debugging console (F12).
Place below line of code inside $(document).ready();
$( document ).ready(function() {
alert('Hello World!');
$('#hello').html('Hello world.');
});
Try this:
$(function()
{
alert("Hello world!");
$("#hello").html("Hello world.");
});
I have created a simple .toggle script on one page to toggle a DIV. But when I put this exact same script on another page to toggle another DIV the second page script fails... I have tried multiple fixes but nothing works
Here is the script I am using on both pages The IDs are different but the script is the same
<script>
$(document).bind('pageinit', function() {
$('#slick-toggle').live('tap', function(event) {
$("#menu_box").toggle(400);
});
});
</script>
Any help would be greatly appreciated
Capt. Crunch
You may try the following:
<script>
$( document ).on( 'pageinit',function(event){
$('#slick-toggle').on('tap', function(event) {
$("#menu_box").toggle(400);
});
});
</script>
Hope this helps, let me know about your result.
In my mobile app, using jQuery Mobile...
I would like to make a simple button execute a simple javascript function on click. No page transitions, nothing special like that.
I understood I can eliminate the page transitions by doing return false or preventDefault()
But the problem is the button sticks with the "active" state, i.e. highlighted blue if you use the general theme. I'm wondering how I can remove that after click (or tap, etc).
Thanks.
You can disable the 'highlighted blue'-state in the 'mobileinit'-event before loading jQueryMobile-script:
<head>
<script>
$(document).bind('mobileinit', function () {
$.mobile.activeBtnClass = 'unused';
});
</script>
<script src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script>
</head>
Now, when you click on a link, no class will be added after the click is performed. You will still have the 'hoover' and 'down' classes.
Update:
This question and the hacks suggested are now a bit outdated. jQuery mobile handles buttons quite a bit differently than 3 years ago and also, jQuery mobile now has several different definitions of "button". If you want to do what the OP was looking for, you might now be able to avoid the issue by using this:
Step 1:
<button class="ui-btn myButton">Button</button>
Alternatively, you could also use jQuery mobile input buttons:
<form>
<input value="Button One" type="button" class="myButton">
<input value="Button Two" type="button" class="myButton2">
</form>
Step 2:
Then your standard jquery on callback:
$(".myButton").on("tap", function(e) {
// do your thing
});
If you are using a button or a tab, or whatever, that has the "active" class applied to it (the default is ui-btn-active), the old answer may still be useful to someone. Also, here is a fiddle demonstrating the code below.
Selectively removing active state:
As demonstrated in another answer, you can disable the active state for all buttons on all pages. If that is acceptable for the project in question, that is the appropriate (and simpler) solution. However, if you want to disable the active state for some buttons while preserving active states for others, you can use this method.
Step 1:
$(document).bind('mobileinit', function() {
$(document).on('tap', function(e) {
$('.activeOnce').removeClass($.mobile.activeBtnClass);
});
});
Step 2:
Then add the activeOnce class (or whatever you want to call it - it's a custom class) to the buttons that you don't want to highlight when clicking.
And as is usual when binding anything to mobileinit, be sure you place your bindings - and perhaps better, all your javascript code - below the jQuery script and above the jQuery-mobile script.
<script src="js/jquery.js"></script>
<script src="js/my_script.js"></script>
<script src="js/jquery.mobile.js"></script>
Do NOT set the activeBtnClass to '' as suggested, this will cause errors when closing dialogs and the pageLoading function.
The method described does work, but cannot be set to null, the activeBtnClass variable is used as a selector, so set it to a non-existent class to get the same effect without the error.
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script type="text/javascript">
$(document).bind('mobileinit', function () {
$.mobile.activeBtnClass = 'aBtnSelector';
});
</script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script>
</head>
This works well to remove the highlight from the buttons while keeping the active state on other elements.
you can just do it via css instead of java:
eg: (you get the idea)
#cart #item_options .ui-btn-active, #cart #item_options .ui-btn-hover-d, #cart #item_options .ui-btn-up-d, #cart #item_options .ui-link-inherit{
background:inherit;
color:inherit;
text-shadow:inherit;
}
What I do is force the buttons to revert to inactive state before a page changes.
//force menu buttons to revert to inactive state
$( '.menu-btn' ).on('touchend', function() {
$(this).removeClass("ui-btn-active");
});
If you want to support non touch devices you should add timeout.
$('.btn' ).on('touchend click', function() {
var self = this;
setTimeout(function() {
$(self).removeClass("ui-btn-active");
},
0);
});
I have spent the good part of a day and night finding the answer to this problem mainly occurring on an android running phonegap. Instead of the standard JQM buttons I am using custom images with :active state in CSS. After following the link to the next page, then clicking back, the button would just stay in the :active state. I have tried adding classes and removing classes and various other suggestions and nothing has worked.
So I came up with my own little fix which works a treat and may help anyone else that is sitting here stumped. I simply call this snippet of code on 'pagecontainerchange' using data.toPage[0].id to only call it on the page where the active state stuck is occurring. Just make sure to wrap your buttons in a div, in my case called "themenu".
function ResetMenu() {
var menuHtml = $("#themenu").html();
$("#themenu").empty().html(menuHtml).trigger("create");
}
This works for a button in the JqueryMobile headerTab
<style>
.Foo {
color: #FFF !important;
background: #347b68 !important;
}
</style>
<div id="headerTab" data-id="headerTab" data-role="navbar">
<ul id="header_tabs">
<li>name
</li>
</ul>
</div>
There seems to be some issues when combining MathJax and jQuery Mobile on the same page. Sometimes the MathJax renders correctly and other times it does not - and this can happen to the same page.
The HTML that loads both of them looks like this:
<script type='text/javascript' src='http://code.jquery.com/jquery.min.js'>
</script>
<script type='text/javascript'
src='http://code.jquery.com/mobile/1.0a4.1/jquery.mobile-1.0a4.1.min.js'>
</script>
<link rel='stylesheet' type='text/css'
href='http://code.jquery.com/mobile/1.0a4.1/jquery.mobile-1.0a4.1.min.css' />
<script src='/beta/mathjax/MathJax.js'>
</script>
You can see an example page here: http://stackmobile.com/beta/math.stackexchange.com/questions/view/?id=47772
Edit: It seems to be a problem with MathJax not recognizing a new page being loaded via AJAX - here is an example that doesn't seem to work: http://stackmobile.com/beta/#/beta/physics.stackexchange.com/questions/view/?id=11678
Well I found a solution... and it goes something like this:
First assign unique numbers to the pages. Since these pages are generated in PHP, this can be accomplished by using uniqid().
Assign the following function the the pageshow event:
$('#page_id').live('pageshow', function(event, ui) {
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'path_to_mathjax/MathJax.js';
script.onload = callback;
document.getElementsByTagName('head')[0].appendChild(script);
});
This loads MathJax and inserts it into the DOM - this script should be included within the page element. Also note that we mention a 'callback'. This will be called when the script loads.
This function (the callback) needs to go outside of any pages. This will prevent it from being included twice after a new page is loaded.
var mathjax_loaded = false;
function callback()
{
if(mathjax_loaded)
MathJax.Hub.Queue(["Typeset", MathJax.Hub]);
else
{
MathJax.Hub.Startup.onload();
mathjax_loaded = true;
}
}
There's a lot here. First of all, we keep track of whether this callback has been called once before. If not, we tell MathJax to parse the page as if it were invoked from the window.onload event. If this has already happened (and we're on a new page) then we simply need to have MathJax run through the new page.
I'm probably missing something and there may be a better way of doing this. But I haven't found any other way that works.
Not sure if this is easier/better way to add a script but here is what I found:
http://api.jquery.com/jQuery.getScript/
Can't append <script> element
(Untested) Maybe (using your post: Combining jQuery Mobile and MathJax on a mobile site?)
$('#page_id').live('pageshow', function(event, ui) {
$.getScript('http://path_to_mathjax/MathJax.js', function() {
callback();
});
});
var mathjax_loaded = false;
function callback()
{
if(mathjax_loaded)
MathJax.Hub.Queue(["Typeset", MathJax.Hub]);
else
{
MathJax.Hub.Startup.onload();
mathjax_loaded = true;
}
}
I am trying to use quickSearch from http://lomalogue.com/jquery/quicksearch/ website. I don't know how to hook to the table so I hoping someone could be kind enough to help me here. I am using VS 2010 MVC 3, in C#, ADO.NET. Thanks in advance. I had a look at related question on the website, if there is a technical gitch? Is there alternative solution? Thanks in advance.
View file Index.cshtml looks like this...
Edited
<script type="text/javascript">
$(function () {
$("table.tablesorter").tablesorter({ widthFixed: true, widgets: ['zebra'],
sortList: [[0, 0]] })
.tablesorterPager({ container: $("#pager"), size: $(".pagesize
option:selected").val() });
});
</script>
<script type="text/javascript">
$(function ()
{
$('input#search').quicksearch('table tbody tr', {selector:'th'});
}
);
</script>
</p>
<table class="tablesorter">
Also it could solve any code organisation problems if you are to wrap the JQuery statement in this
$(document).ready(function() {
$('input#search').quicksearch('table tbody tr', { selector: 'th' });
});
Also the table quick search plugin i use is JQuery table search plugin, it works well and if you just take a quick look at the demo it is rather easy to implement and does not clash with most other JQuery table plugins.
While I haven't used QuickSearch before, and I'm not sure if it'll solve all of your problems, but as a start it appears that you've put your first script element too early in your document.
You need to put it after the other script elements.
this:
<script type="text/javascript">
$('input#search').quicksearch('table tbody tr', { selector: 'th' });
</script>
should appear after the the jquery script, and the quicksearch script elements. If you include it before, the browser doesn't know what $ and $(selector).quicksearch is.
btw: this:'input#search' selector is not needed.
you can use the #search selector to same effect, becuase searching by id is a one command in JS.
