When I do this:
$('head').append('<script type="text/javascript" src="script.js"></script>');
then script.css is loaded and executed, and is available for use immediately.
But when I do this:
$('head').append('<link rel="stylesheet" type="text/css" src="sheet.css" />');
then sheet.css is not loaded. However when I look at the generated source, the line in question has been added to the object.
Apparently scripts and style sheets are being treated differently by the browser.
Why?
For link element, specify the source of external stylesheet in href attribute. You need to update your code from
$('head').append('<link rel="stylesheet" type="text/css" src="sheet.css" />');
to
$('head').append('<link rel="stylesheet" type="text/css" href="sheet.css" />');

I have CSS order like this:
<link rel="stylesheet" href="style2.css">
<link rel="stylesheet" href="style1.css">
What I want to achieve is order like this:
<link rel="stylesheet" href="style1.css">
<link rel="stylesheet" href="style2.css">
The ideal would be if this can be done when page loads.
I don't see why you need to have to do it with JavaScript, but here's the answer:
$("LINK[rel='stylesheet']")
you can use this jquery code in order to get the all the link tags for stylesheets. Using array manipulation, you could change the order. More info about this specific snippet here
then once you are ready, you could loop over the code. More info about this from here
$('head').append('<link rel="stylesheet" type="text/css" href="lightbox_stylesheet.css">');
obviously, change what you are appending.
I cant understand the error where $ is unidentified when using onload on my page. This is just as sample page I created where I need to call a function after loading the page.
Jquery Code
$(document).ready(function(){
alert("loaded");
});
<html>
<head>
</head>
<body>
</body>
<script src="../Jquery/contact.js"></script>
<script src="../Jquery/jquery-1.12.0.min.js"></script>
<script src="../Jquery/jquery-migrate-1.2.1.min.js"></script>
<script src="../Jquery/jquery.SPServices-2014.01.min.js"></script>
<link rel="stylesheet" type="text/css" href="../CSS/default.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap.min.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap-theme.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap-theme.min.css"/>
</html>
Two issues here:
It's invalid to put script or link tags as direct children of html, so it doesn't surprise me that it doesn't work correctly on at least some browsers. You need to put them in the body or head. The only valid content of the html element is a single head element followed by a single body element.
Standard guidance, for instance in the YUI Best Practices for Speeding Up your Website is:
Put the link tags in head
Put the script tags at the bottom of body, just prior to the closing </body> tag
It looks like your contact.js file calls $() immediately (not in response to an event). If so, then contact.js must be after jQuery in the list of scripts, so that jQuery has been loaded when your code runs.
So:
<html>
<head>
<link rel="stylesheet" type="text/css" href="../CSS/default.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap.min.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap-theme.css"/>
<link rel="stylesheet" type="text/css" href="../bootstrap-3.3.6-dist/css/bootstrap-theme.min.css"/>
</head>
<body>
<script src="../Jquery/jquery-1.12.0.min.js"></script>
<script src="../Jquery/jquery-migrate-1.2.1.min.js"></script>
<script src="../Jquery/jquery.SPServices-2014.01.min.js"></script>
<script src="../Jquery/contact.js"></script>
</body>
</html>
Side notes:
You might look at script and CSS combining and minifying, to avoid having a lot of HTTP requests.
Consider adding <!doctype html> at the very top to ensure the browser is in standards mode (not quirks mode).
Consider adding <meta charset="UTF-8"> at the top of head (ensuring that the file is indeed in UTF-8, or changing the "UTF-8" in that to whatever encoding you're actually using in the file).
thanks for the input. so basically I had 2 problems on this. I solved the first one by moving the contact.js to the bottom and removing the migrate plugin.
I need to use javascript to load a different stylesheet based on a URL variable that is being passed.
The scenario is this: We need to maintain a mobile website with one CSS stylesheet, and a different stylesheet that will be used to style the same page when it is accessed via a web-view loaded in an iOS app.
If you look at www.blog.meetcody.com you'll see that we're already using media queries and responsive webdesign. The reason that this is insufficient for us is because media queries cannot detect if the page is being loaded via a webview in a native app vs. a mobile safari. We need to handle these two cases separately. The blog is a hosted wordpress blog, that we are accessing via a JSON API in our iOS app.
The way we are handling this is as follows: When the webpage is loaded via our iOS app, we append a variable to the end of the URL "/?app=true". What I'd like to do is check to see if the URL contains this string, and if so, use a different webview.
I am attempting to do this with the below code:
<script language="javascript" type="text/javascript">
if(window.location.href.indexOf('/?app=true') > -1) {
document.write("<link rel=\"stylesheet\" type=\"text/css\" href=\"http://blog.meetcody.com/wp-content/themes/standard/appstyle.css\" />");
}
document.close();
</script>
The issue that I'm having is that the above code doesn't actually load the appstyle.css stylesheet when ?app=true is part of the URL.
If you take a look at http://blog.meetcody.com/wp-content/themes/standard/appstyle.css?ver=3.4.2 you can see that I'm testing this by setting the background: black in the body {} tag
body {
background: black;
}
Whereas, in style.css at http://blog.meetcody.com/wp-content/themes/standard/style.css?ver=3.4.2 the body background color is #F2F0EB; in the body {} tag
body {
background: #F2F0EB;
}
Of course, we want to do more than just change the background color, but I'm just showing this as an example.
Is there a better way to do this, or is there something wrong with my code? Perhaps I cannot use a direct link to appstyle.css an href in javascipt? Help much appreciated. And Merry Christmas!
You can add a CSS stylesheet by using appendChild() like this:
var header = $.getElementsByTagName('head')[0];
var styleSheet = $.createElement('link');
styleSheet.rel = 'stylesheet';
styleSheet.type = 'text/css';
styleSheet.href = 'style.css'; // name of your css file
styleSheet.media = 'all';
header.appendChild(styleSheet);
Of course you could change this example to accomodate different css file names depending on the current URL by doing something like this:
styleSheet.href = (isMobile == true) ? 'mobile.css' : 'default.css';
You should never try to close the document when you use inline script. document.close is only needed if you document.write to an iframe, frame or new window
Also I suggest you test the location.search rather than the href since that is where you placed the flag.
Please try
<script language="javascript" type="text/javascript">
if (location.search.indexOf('app=true') > -1) {
document.write('<link rel="stylesheet" type="text/css" href="http://blog.meetcody.com/wp-content/themes/standard/appstyle.css" />');
}
</script>
and possibly place that script AFTER the other stylesheets, if you want to override stuff set in one of your 10+ sheets at your site, or better: test the query string on the server, or where you set the query string to app=yes, set something in the session or similar and use that to include the correct css on the server instead of relying on JS
PS: Your body tag has the classes of home and blog on your homepage. I suggest you look to the above mentioned stylesheets and see what the colour is in those for those classes.
PPS: I do not see any media detection here

I have a master page with the following lines inside my <head> tags.
<link href="Styles/Style.css" rel="stylesheet" type="text/css" />
<script src="Scripts/navmenu.js" type="text/javascript"></script>
When I navigate to a page that uses URL routing, the lines above generate the following HTML.
<link href="../../Styles/Style.css" rel="stylesheet" type="text/css" />
<script src="Scripts/navmenu.js" type="text/javascript"></script>
Based on the mapped URL, the stylesheet link is correct. How can I get the script link to also be correct?
P.S. I tried setting runat="server" in the script link but that just seems to confuse ASP.NET. The entire project fails to compile based on bogus errors reported in my JavaScript file. (The javascript file runs fine otherwise.)
It looks like the best answer is this:
<link href="Styles/Style.css" rel="stylesheet" type="text/css" />
<script src='<%= ResolveClientUrl("~/Scripts/navmenu.js") %>' type="text/javascript"></script>
Note that if I use the ResolveClientUrl() for the stylesheet <link> tag, it doesn't work. Apparently, there is special handing for this tag.
I am trying to load my print.css but it does not seem to be loading. it work Fine in FF and Safari but the problem is only in IE.
I have the regular external css for the page inbetween the head tags
And when the user click on the print link . it loads the print css .
<div class="linkPrint">
<a target="_blank" href="?format=print">Print</a>
</div>
var format = getUrlParam('format');
if (format == 'print') {
$('head').append('<link href="/theme/print.css" rel="stylesheet" type="text/css" />');
}
But,in IE it load the standard css instead of the print.css.
How do can this be fixed for IE6?
Thanks
You can have the print CSS and your screen CSS both loaded at the same time on the page without them interfering with each other - you need to specify the media attribute on the link tag:
<link href="/theme/print.css" rel="stylesheet" type="text/css" media="print" />
<link href="/theme/screen.css" rel="stylesheet" type="text/css" media="screen" />
No need to go through the javascript trickery.
As for IE6 - it does support this, as can be seen on the comparison list on this page.
Try removing the <link> to the other css file when you append the print.css
try with document.write,
document.write('<link href="/theme/print.css" rel="stylesheet" type="text/css" />');
