I'm creating a website that uses jQuery .load() to present content that is stored in divs on another .html page, as follows
index.html head:
<link href="css/prism.css" rel="stylesheet" />
<script type="text/javascript" src="js/prism.js"></script>
index.html:
$('#content').load('project_info.html #example', function() { $(this).fadeIn(".25s"); });
project_info.html's corresponding div:
<div id="example">
<pre><code class="language-css">p { color: red }</code></pre>
</div>
I'm trying to get the prism.js code block to display correctly, and while
<pre><code class="language-css">p { color: red }</code></pre>
works properly when I embed it in index.html, it won't seem to inherit the prism.js file, just the prism.css stylesheet. It seems the prism.js file won't manipulate the "content" div. Any ideas?
After you load the remote content onto your page, you'll need to manually apply prism to it. After some brief search, looks like prism.js provides this method:
highlightElement: function(element, async, callback) { ... }
I'm assuming can use Prism.highlightElement(document.getElementById('example')) to highlight the code inside #example.
(Also see this example: https://github.com/PrismJS/prism/blob/b551696fbdf8905d52ca67e1a9ae50a3ccfeab92/examples.js)

I’m including one HTML file in another, as a way to reuse my header and navigation generation logic.
The trouble is that when I browse to pages on my site, I can see the HTML that isn’t included in the include files load first. Only then you can see the menus and banners load afterwards. I’d like everything to appear to load at the same time.
Here's the rendered HTML.
And here’s a code snippet showing you how I generate these pages:
<!DOCTYPE html>
<html lang="en">
<head>
<script src="assets/js/jquery-2.1.3.min.js"></script>
<script>
$(function(){
$("#includeHeader").load("includes/templates/header.html");
$("#includeNavigation").load("includes/templates/navigation.html");
});
</script>
<div id="includeHeader"></div>
</head>
<body>
<div id="wrapper">
<!-- Navigation -->
<div id="includeNavigation"></div>
I’m currently working with the code to try to move any external libraries / CSS to the bottom of the page vs. in the header. But so far, that hasn’t really changed or improved anything.
You should use one of the templating languages.
If your includes are simple HTML files then you could use Handlebars or Dust - you could just copy your code and that's it, then in Javascript you would need just render these templates - see the documentation.
You could use Jade/Pug instead, but its syntax is different from the HTML, so that's not just question of copy-paste.
You are using $(handler) to load them, which is a form for $.ready(). So it waits for the document to load everything before loading your header.html and navigation.html.
Try
<head>
<script src="assets/js/jquery-2.1.3.min.js"></script>
</head>
<body>
<div id="includeHeader"></div>
<script>
$("#includeHeader").load("includes/templates/header.html");
$("#includeNavigation").load("includes/templates/navigation.html");
</script>
</body>
Your problem is that the load function does not run until the document.ready event has fired. Which is probably after your page has started rendering. To get everything to appear at the same time you could use the callback from .load to show everything. So everything is hidden,
$( "#result" ).load( "ajax/test.html", function() {
/// show your stuff
});
You will of course need to know both has loaded.
I would recommend not using javascript to render HTML from a static path and would use a server side lang instead for speed.
I think it make some level fast its not waiting for load all dom element, I am considering #includeNavigation element is under #includeHeader element
<head>
<script src="assets/js/jquery-2.1.3.min.js"></script>
</head>
<body>
<div id="includeHeader"></div>
<script>
$("#includeHeader").load("includes/templates/header.html", function(data){
console.log("header loaded");
$("#includeNavigation").load("includes/templates/navigation.html", function(data){
console.log("navigation loaded");
});
});
</script>
</body>
In my content editor you can change custom webfonts on the fly. If you change a font, it deletes all scripts and styles using the data-attribute as an identifier and the new ones then get appended after an ajax call. Now after some testing i realised it work's very well with css files but it ignores the < script >'s. Any ideas? Here is my Script:
$('head').find('[data-fontset-id=ce-fontset]').each(function() {
$(this).remove();
});
For example this is how the head section looks like:
<link data-fonset-id="ce-fontset" rel="stylesheet" href="..........">
<script data-fonset-id="ce-fontset" type="text/javascript" src="//use.typekit.net/xxxxx.js"></script>
<script data-fonset-id="ce-fontset" type="text/javascript">try{Typekit.load();}catch(e){}</script>
In this example, the css file gets removed but the javascript files didnt, any ideas why they are being ignored?
Thanks a lot in advance,
Michael
I haven't used jQuery before, and I wanted to use DateTimePicker plugin on my web page.
I downloaded the plugin file and placed them in the same directory as the HTML files.
I directly applied the code at How to use it? in http://xdsoft.net/jqplugins/datetimepicker/.
It threw the following error.
Uncaught TypeError: undefined is not a function pixelcrawler:61 (anonymous function)
My code follows.
<script type='text/javascript' src="//ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<link rel="stylesheet" type="text/css" href="file:///jquery.datetimepicker.css"/ >
<script src="file:///jquery.datetimepicker.js"></script>
<script>
jQuery('#datetimepicker').datetimepicker();
</script>
<div class="container">
<div class="text-center">
<div class="page-header">
<h1>${conf['title']} <small>${conf['description']}</small></h1>
</div>
</div>
<div class="text">
<input id="datetimepicker" type="text" >
.
.
.
.
.
I could not figure out what the problem was. I have tried many other seemingly likely options, but it just did not work either.
(The ${} tags are used for the Mako template language. I am using Cherrypy.)
UPDATE:
I figured out the source of the problem.
It's from jQuery('#datetimepicker').datetimepicker();.
When tested, the datetimepicker() function was undefined. Maybe the way I imported the library was wrong?
jQuery(document).ready(function(){
jQuery('#datetimepicker').datepicker();
})
I don't know your file-structure. I never include local files like this as I use relative URLs from the start rather than having to change everytime I'm ready to use the code, but it's likely one of the files isn't being loaded in. I've included the standard datepicker below using Google CDN's jQuery UI. Does your console log any resources not found?
I think your jQuery is loaded OK, because it's not telling you jQuery is not defined so it's one of your files.
BTW, PHP gets the home URL:
$home="http://" . $_SERVER['HTTP_HOST'].'/';
Demo code datepicker, jQuery UI:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/smoothness/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){
jQuery('#datetimepicker').datepicker();
})
</script>
<input id="datetimepicker" type="text">
This is about the HTML parse mechanism.
The HTML parser will parse the HTML content from top to bottom. In your script logic,
jQuery('#datetimepicker')
will return an empty instance because the element has not loaded yet.
You can use
$(function(){ your code here });
or
$(document).ready(function(){ your code here });
to parse HTML element firstly, and then do your own script logics.
use jQuery.noConflict()
var j = jQuery.noConflict();
j(document).ready(function(){
j('#datetimepicker').datepicker();
})
For my situation, it was a naming conflict problem. Adding $J solves it.
//Old code:
function () {
var extractionDialog;
extractionDialog = $j("#extractWindowDialog").dialog({
autoOpen: false,
appendTo: "form",
height: "100",
width: "250",
modal: true
});
$("extractBomInfoBtn").button().on("click", function () {
extractionDialog.dialog("open");
}
And the following is new code.
$j(function () {
var extractionDialog;
extractionDialog = $j("#extractWindowDialog").dialog({
autoOpen: false,
appendTo: "form",
height: "100",
width: "250",
modal: true
});
$j("extractBomInfoBtn").button().on("click", function () {
extractionDialog.dialog("open");
});
});
Hope it could help someone.
Usually when you get this problem, it happens because a script is trying to reference an element that doesn't exist yet while the page is loading.
As richie mentioned: "The HTML parser will parse the HTML content from top to bottom..."
So you can add your JavaScript references to the bottom of the HTML file. This will not only improve performance; it will also ensure that all elements referenced in your script files have already been loaded by the HTML parser.
So you could have something like this:
<html>
<head>
<!-- Style sheet references and CSS definitions -->
</head>
<body>
<!-- HTML markup and other page content -->
<!-- JavaScript references. You could include jQuery here as well and do all your scripting here. -->
</body>
</html>
You may see if you are not loading jQuery twice somehow. Especially after your plugin JavaScript file loaded.
I has the same error and found that one of my external PHP files was loading jQuery again.
The issue because of not loading jquery ui library.
https://code.jquery.com/ui/1.11.4/jquery-ui.js - CDN source file
Call above path in your file.
And if you have this problem in slider or slideshow you must use jquery.easing.1.3:
<script src="http://gsgd.co.uk/sandbox/jquery/easing/jquery.easing.1.3.js"></script>
I had trouble getting selectable to work with ASP.NET. It turns out I wasn't properly including everything, but this gentleman made it foolproof: Three steps to use jQuery UI in ASP.NET MVC 5.
I don't think jQuery itself includes datetimepicker. You must use jQuery UI instead (src="jquery.ui").
I am creating a website (http://yic.am) using wordpress and the theme includes a background and a "subpage_content_bg". The subpage-background is a semi-transparent white background that wraps around the content making it easier to read. I would like the subpage background to become position:fixed instead of position:absolute when you scroll down, so that when it reaches the top of the page it scrolls with the page.
I have found several pages describing and demonstrating the function when the subject is a picture, comment box or text in the actual post or page. However, I cannot seem to find a description for when the picture is a part of the css stylesheet.
The subpage-extract from the stylesheet looks like this:
#sp .content_wrapper_sbl {
width:940px;
min-height:320px;
margin:-107px auto 0;
padding:45px;
position:relative;
z-index:20;
background:url(../../images/subpage_content_bg.png) 0 0 no-repeat;
}
Where should I place the javascript for the function (I am trying to use the function from the above link)? I would like it to be for all pages and posts (except the cover-page)
How do I make the subpage image the target of the function? Is it possible to make the #sp or content_wrapper_sbl the target?
I have been trying a lot of different things for a lot of times - but I am very new to web-designing and coding. I hope all the necessary information is included - any help would be much appreciated.
The code I am working is this: http://jsfiddle.net/EahRx/870/
It looks like you've pretty much got it nailed in that fiddle, haven't you? It's personal preference how you want to arrange your javascript files, I guess. Personally, I like to use the Google library to load my jQuery...
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
and then load any other plugins you might be using...
<script src="http://www.mydomain.com/js/jquery.plugin1.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin2.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin3.js"></script>
and finally I usually build a custom jQuery file and call it, surprise surprise, "jquery.custom.js"...
<script src="http://www.mydomain.com/js/jquery.custom.js"></script>
So the final javascript include list looks like this...
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin1.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin2.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin3.js"></script>
<script src="http://www.mydomain.com/js/jquery.custom.js"></script>
This way the jQuery library is loaded first because the likelihood is that all other javascript files depend on it. Then the plugins are loaded, finally your custom file is loaded because that might depend on some of the earlier plugins being loaded first - for example, your custom file might want to tweak a slideshow file loaded in one of your plugins.
If, for any reason, you are not able to edit the head of your template file to add your javascript include you can add it to the bottom of your HTML like this...
<head>
[META INFO & TITLE]
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin1.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin2.js"></script>
<script src="http://www.mydomain.com/js/jquery.plugin3.js"></script>
[CSS AND STUFF]
</head>
<body>
[YOUR WEB PAGE STUFF]
<script src="http://www.mydomain.com/js/jquery.custom.js"></script>
</body>
</html>
Hope this helps point you in the right direction.
Oh, and remember to add the old "document ready" gubbins to the jquery.custom.js file too...
$(document).ready(function(){
[YOUR JQUERY HERE]
});
New to designing on the Volusion platform and stuck after investigating the help topics on the support forms. I need to override a CSS style on all pages but my default.asp homepage. I am attempting to do this with javascript but it doesn't seem to be working.
Here is the demo for the site: http://v1330583.ovjk2w9aumkd.demo19.volusion.com/default.asp
I am attempting to modify my #content rule by beginning with this Javascript:
<script type="text/javascript">
//<![CDATA[
if (location.pathname == "/ProductDetails.asp") ||
location.pathname.indexOf("-p/") != -1 ||
location.pathname.indexOf("_p/") != -1)
var onHomepage = true;
if(!onHomepage)
document.writeln("\n<style type='text/css'>content {
padding: 20px background-color: #fff}</style>\n\n");
//]]> </script>
Can anyone tell me
Where I should inset this code.
If there is a better way to do this.
Would really appreciate any help!
There's a much simpler way to do this in Volusion without Javascript. If you log in to your dashboard, go to 'Design->File Editor" and then click on the template HTML file (it will be under the heading 'Template Files', you'll be in the main template file for your site.
In between the <body> tags you'll just add a div with an id of "if_not_homepage" and the site will only read the contents of this div if not on the default.asp page. For example:
<div id="if_not_homepage">
<style type="text/css">
#content{
padding:20px;
background-color:#fff;
}
</style>
</div>
OR you could call a separate stylesheet completely from within this div (for example):
<div id="if_not_homepage">
<link rel="stylesheet" href="/v/vspfiles/templates/YOUR_TEMPLATE/css/inner_style.css" />
</div>
If you place the stylesheet within the directory "/v/vspfiles/templates/YOUR_TEMPLATE/css/" you'll be able to edit the stylesheet from within the File Editor in the Volusion dashboard as well (like your other stylesheets).
Alternately, there is a div with an id of "if_homepage" that is read only if the user is on the default.asp (opposite of "if_not_homepage").
On a completely separate note, in your code above, you are missing either a class (.) or id (#) selector on 'content' in your CSS, so that may have something to do with it as well.
Instead of a style tag, I think you are better off setting the style directly with jQuery (if the DOM is loaded) or writing out a link tag to a separate style sheet.
