I am trying to use tablesorter.js with DocPad. I have added the required lines to docpad.coffee to load the css and js for the tablesorter, and I have added the call to tablesorter() in the page where I have the the table I want to sort.
However, the resulting tables do not sort properly for two reasons: All scripts are deferred (defer="defer") and the call to tablesorter() appears before the scripts are loaded, like this:
</tbody></table></p>
<script>
$(document).ready(function(){$("#mytable").tablesorter();})
</script></div>
</article>
...
<!-- Scripts -->
<script defer="defer" src="/vendor/jquery/1.10.2/jquery.min.js"></script>
<script defer="defer" src="/vendor/jquery/tablesorter/jquery.tablesorter.js"></script>
<script defer="defer" src="/vendor/modernizr/2.6.2/modernizr.min.js"></script>
<script defer="defer" src="/vendor/twitter-bootstrap/dist/js/bootstrap.min.js"></script>
<script defer="defer" src="/scripts/script.js"></script>
</body>
If I delete the defer stuff and move the tablesorter() call down, it works fine:
<!-- Scripts -->
<script src="/vendor/jquery/1.10.2/jquery.min.js"></script>
<script src="/vendor/jquery/tablesorter/jquery.tablesorter.js"></script>
<script src="/vendor/modernizr/2.6.2/modernizr.min.js"></script>
<script src="/vendor/twitter-bootstrap/dist/js/bootstrap.min.js"></script>
<script src="/scripts/script.js"></script>
<script>
$(document).ready(function(){$("#mytable").tablesorter();})
</script>
</body>
I need to get rid of the defer setting and I need to call tablesorter() after the scripts have been loaded. How can I do this in DocPad 6.59.6?
I found a fix and a workaround to get tablesorter working.
The sequence issue: In order to load all Javascript before the call
to tablesorter(), I moved the scripts section in the default layout
(src/layouts/default.html.eco) to be loaded as part of the <head/>,
not as the lats part of the <body/> as it originally was.
The defer issue: I couldn't figure out how to modify Docpad's
#getBlock('scripts') to not include the defer="defer" setting.
The workaround was then to not use getBlock and instead just
hardcode the references to the script files.
In summary, going from this:
<html>
...
<body>
...
<%- #getBlock('scripts')...
</body>
</html>
to this:
<html>
<head>
...
<script src="/vendor/jquery/...
...
</head>
<body>
...
</body>
</html>
fixed the problem. I now have a maintenance problem that I have to maintain the list of scripts within the layout (instead of using the scripts: section in docpad.coffee); I can live with that.

I am having an issue getting a dialog to work as basic functionality. Here is my jQuery source imports:
<script type="text/javascript" src="scripts/jquery-1.9.1.js"></script>
<script type="text/javascript" src="scripts/jquery-ui-1.11.1.js"></script>
<script type="text/javascript" src="scripts/json.debug.js"></script>
Html:
<button id="opener">open the dialog</button>
<div id="dialog1" title="Dialog Title" hidden="hidden">I'm a dialog</div>
<script type="text/javascript">
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
</script>
From the posts around seems like as a library import issue. I downloaded the JQuery UI Core, Widget, Mouse and Position dependencies.
Any Ideas?
Be sure to insert full version of jQuery UI. Also you should init the dialog first:
$(function () {
$( "#dialog1" ).dialog({
autoOpen: false
});
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
});
<script src="https://code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="https://code.jquery.com/ui/1.11.1/jquery-ui.min.js"></script>
<link rel="stylesheet" href="https://code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css" />
<button id="opener">open the dialog</button>
<div id="dialog1" title="Dialog Title" hidden="hidden">I'm a dialog</div>
if some reason two versions of jQuery are loaded (which is not recommended), calling $.noConflict(true) from the second version will return the globally scoped jQuery variables to those of the first version.
Some times it could be issue with older version (or not stable version) of JQuery files
Solution use $.noConflict();
<script src="other_lib.js"></script>
<script src="jquery.js"></script>
<script>
$.noConflict();
jQuery( document ).ready(function( $ ) {
$("#opener").click(function() {
$("#dialog1").dialog('open');
});
});
// Code that uses other library's $ can follow here.
</script>
If you comment out the following code from the _Layout.cshtml page, the modal popup will start working:
</footer>
#*#Scripts.Render("~/bundles/jquery")*#
#RenderSection("scripts", required: false)
</body>
</html>
Change jQueryUI to version 1.11.4 and make sure jQuery is not added twice.
I just experienced this with the line:
$('<div id="editor" />').dialogelfinder({
I got the error "dialogelfinder is not a function" because another component was inserting a call to load an older version of JQuery (1.7.2) after the newer version was loaded.
As soon as I commented out the second load, the error went away.
Here are the complete list of scripts required to get rid of this problem.
(Make sure the file exists at the given file path)
<script src="#Url.Content("~/Scripts/jquery-1.8.2.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery-ui-1.8.24.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript">
</script>
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript">
</script>
and also include the below css link in _Layout.cshtml for a stylish popup.
<link rel="stylesheet" type="text/css" href="../../Content/themes/base/jquery-ui.css" />
I had a similar problem and in my case, the issue was different (I am using Django templates).
The order of JS was incorrect (I know that's the first thing you check but I was almost sure that that was not the case, but it was). The js calling the dialog was called before jqueryUI library was called.
I am using Django, so was inheriting a template and using {{super.block}} to inherit code from the block as well to the template. I had to move {{super.block}} at the end of the block which solved the issue. The js calling the dialog was declared in the Media class in Django's admin.py. I spent more than an hour to figure it out. Hope this helps someone.
I am working through the dart todo sample application. I haven't changed any code but I see lots of squiggles in the editor.
<polymer-element name="simple-router">
<script type="application/dart;component=1"
src="simple_router.dart"></script>
</polymer-element>
The error I'm seeing reads.
Wrong script type, expected
type="application/dart".
I don't understand what this means. When I strip off the ;component=1. It really breaks the application.
This is code that was valid in Polymer about ">= 0.10.5 <0.11.0" but there were several changes.
;component=1 Should be remove from all script tags.
The imports and script tags in the entry page should look like
<html>
<head>
<title>core-ajax-dart</title>
<!-- when the project uses polymer -->
<!-- <script src="packages/web_components/platform.js"></script>
not necessary anymore with Polymer >= 0.14.0 -->
<script src="packages/web_components/dart_support.js"></script>
<!-- import individual polymer elements -->
<link rel='import' href='packages/core_elements/core_ajax_dart.html'>
</head>
<body>
<core-ajax-dart
url="http://gdata.youtube.com/feeds/api/videos/"
params='{"alt":"json", "q":"chrome"}'
handleAs="json"
auto></core-ajax-dart>
<!-- if you have a custom script file that contains a main() method -->
<script type="application/dart" src="core_ajax_dart.dart"></script>
<!-- else if you don't have a custom script file with a main() method
<script type="application/dart">export 'package:polymer/init.dart';</script>
</body>
</html>

It's been a nightmare to me before I came to know that in order to get jquery ui working in ASP.NET MVC I need to add #Scripts.Render("~/bundles/jqueryui"). Before doing so I kept getting Uncaught error: Undefined is not a function. What I did not understand was why on earth this would happen when I could see the jquery ui file in the sources when inspecting the html source. This is the _Layout.cshtml file:
<!DOCTYPE html>
<html>
<head>
<script src="~/Scripts/jquery-1.8.2.js"></script>
<script src="~/Scripts/jquery-ui-1.8.24.min.js"></script>
<link href="~/Content/themes/base/jquery-ui.css" rel="stylesheet" />
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>
<script src="~/Scripts/jquery.plugins.js"></script>
<script src="~/Scripts/Helpers.js"></script>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<title>#ViewBag.Title</title>
#Styles.Render("~/Content/css")
#Scripts.Render("~/bundles/modernizr")
</head>
<body>
#RenderBody()
#Scripts.Render("~/bundles/jquery")
#Scripts.Render("~/bundles/jqueryui")//Added later to get it working
#RenderSection("scripts", required: false)
</body>
</html>
In my Helper.js file I have some helper functions that I usually use. One of them is applyDatetimePickerAndFormat that is called on $(document).ready(). Inside that function I have the following code:
$('.txt-date').datepicker({
showAnim: "drop",
changeMonth: true,
changeYear: true,
dateFormat: "dd.mm.yy"
});
If I omit #Scripts.Render("~/bundles/jqueryui") in the _Layout.cshtml I will get the aforementioned error. This code works perfectly with any plain html or web form. So it seems that somehow the document can't see the contents of the jquery-ui file. To make my question concrete:
When I look at the Sources of the the web page I can see jquery-ui-1.8.24.js and it's referenced in the html source. Then why can't the code find jquery-ui functions?
If every java script file has to be specified in the #Scripts.Render then why isn't there any problem with my Helper.js file?
And finally where does this ~/bundles/jqueryui path refer to?
jquery-ui depends on jquery (i.e. it must be defined after jquery) but you have duplicated your files. In the head you have included <script src="~/Scripts/jquery-1.8.2.js"></script> followed by jquery-ui. You then reload jquery at the end of the file using #Scripts.Render("~/bundles/jquery") (Its now after jquery-ui).
Delete the script in the head and it should work. I addition, I recommend you delete jquery.validate and jquery.validate.unobtrusive from the head and use #Scripts.Render("~/bundles/jqueryval") at the end of the file (before #RenderSection..). You can examine these bundles in App_Start\BundleConfig.cs file. There are numerous advantages to using bundles (see Bundling and Minification).
If you are using all these files in every page based on _Layout, you can define your own bundle to includes all files.
You need to define the strategy for your js. I recomend you ot organize your js first and after that separate it to smaller parts. One should be common for all the pages(jQuery in your case) and other scripts for validation should be included only on pages that have some editing fileds etc.
Use DRY principle and read some information about how js works. It helps me a lot some time ago and won't take a lot of time.
I see some others (e.g. this post) have had trouble using external javascript scripts in JQuery Mobile - as of today I have joined their ranks.
I have a single external js script (controllers.js) which contains code that affects several pages on the site. It is loaded on every page of the site. I put the js file just before the tag it works fine on the initial page load. However when I navigate thereafter (using the JQM Ajax methods) all functions in the script stop working. I would have thought the script would remain in cache - but heyho. Anyhow there's an FAQ which answers this question and I've implemented their suggestion which is: "...to reference the same set of stylesheets and scripts in the head of every page." I have done this but when I do even on the first page load the js doesn't fire. There aren't page specific scripts - so the remainder of that FAQ does not apply.
My cut down html looks like this:
<!doctype html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="stylesheet" href="/static/jquery-ui-1.10.3.custom.min.css">
<link rel="stylesheet" href="/static/jquery-mobile/css/themes/default/jquery.mobile-1.3.2.min.css">
<script src="/static/jquery-1.9.1.min.js"></script>
<script src="/static/jquery-ui/jquery-ui-1.10.3.custom/js/jquery-ui-1.10.3.custom.min.js"></script>
<script src="/static/jquery-mobile/js/jquery.mobile-1.3.2.min.js"></script>
<!-- CSS: implied media="all" -->
</head>
<body>
<div data-role="page" id = "main-page">
<div data-role="header" style="overflow:hidden;">
</div>
<div id = "home" data-role="content">
<input type ='button' id = "some_btn" value="press me">
</div>
</div>
<script type="text/javascript" src="/static/js/controllers.js"></script>
</body>
</html>
and within the javascript file
controllers.js
$('#some_btn').click(function()
{
alert('button pressed');
});
Any ideas on what I may be doing wrong here?
Since the content in the #page is loaded dynamically via ajax, click will not work, since it only works on elements that are on the page when the script is called.
You need to use the .on() method:
$('body').on('click','#some_btn',function()
{
alert('button pressed');
});
I embedded phoneGap in my UIWebView, referenced to this doc:
http://docs.phonegap.com/en/2.2.0/guide_cordova-webview_ios.md.html#Embedding%20Cordova%20WebView%20on%20iOS
And in the index.html, I write this sample code:
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
alert(“jquery loaded”);
});
</script>
</head>
<body>
<h2>This is a heading</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>Click me</button>
</body>
after the webview loaded, the "body" can be shown, but the alert can't be pop out. So the jquery.js is not loaded? Or something else is wrong?
Edit:
I added "http:" to the src, but not work.
Thanks!
change
alert(“jquery loaded”);
to
alert("jquery loaded");
or
alert('jquery loaded');
Add http or https to your code
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
The above should work for you.
Did you add the Cordova file?
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="./cordova-2.3.0.js"></script>
<script>
$(document).ready(function() {
alert(“jquery loaded”);
});
</script>
</head>
<body>
<h2>This is a heading</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>Click me</button>
</body>
</html>
Also as much as phonegap uses HTML 5 it still requires a bit different style of writing your code. Everypage you make should all be in the same index page because Cordova loads at startup in your project. If you navigate away from the page Cordova needs to reload.
Did you copy jquery file at www forder (www/jquery.js). I use jquery too, mine is www/js/jquery.js
Try this!!!
