I have a website using twitter bootstrap. When developing sometimes the internet is not working so jquery won't be loaded and my site will not work. This is why I have a local copy of jquery in my js folder. I edited bootstrap files so if jquery is not detected the browser will change the location of jquery from cdn to my local file. I tried to do that but it is not working:Here is my code:
if (!window.jQuery) {
document.getElementById('jq').src='../../js/jquery.js';
console.log("You are using a backup file of jquery provided by our website");
}
else{
console.log("jQuery has been succesfully loaded by kounelios13");
}
html:
<script src="http://code.jquery.com/jquery-1.11.0.min.js" id="jq"></script>
<script src="../../js/bootstrap.js" type="text/javascript"></script>
<script src="../../js/prefixfree.js" type="text/javascript"></script>
<script src="../../js/apps/rgba.js" type="text/javascript"></script>
This is placed inside bootstrap's js file.
Any ideas???
Imaging that CDN file is not available. Then browser starts loading next script file (bootstrap.js), parser enters bootstrap.js, where you placed your check for jQuery. Your code detects that jQuery is not loaded and the script then changes src of the jq tag. It works fine and jQuery starts loading, however browser doesn't wait until jQuery is downloaded and carry on to the Bootstrap stuff, which fails immediately, because it requires jQuery. Hence the error.
You can try this version for backup jQuery library instead which should be reliable:
<script src="http://code.jquery.com/jquery-1.11.0.min.js" id="jq"></script>
<script>
if (!window.jQuery) {
document.write("<script src='../../js/jquery.js'>\x3C/script>");
}
</script>
<script src="../../js/bootstrap.js" type="text/javascript"></script>
<script src="../../js/prefixfree.js" type="text/javascript"></script>
<script src="../../js/apps/rgba.js" type="text/javascript"></script>
With jquery I don't thinks bootstrap script work so you need that.
If you have internet problem then you can copy jquery link and make file of that and attached.
ID must unique for the Document, you have another Element that uses the id jq or none.

This is the code I use to show a message on my webpage.
<script type="text/javascript" src="jquery-1.9.1.js"></script>
<script type="text/javascript" src="jquery-migrate-1.0.0.js"></script>
<script>
$(document).ready(function(e) {
alert('success');
});
</script>
However, after the page loads it shows me nothing.
try loading the jquery files from a cdn, unless you're already hosting it-
e.g.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
edit:
you say it's already apart of your server, I personally prefer making absolute paths to files..
e.g.
<script src="http://your.server.com/path/to/the/files/jquery.1.9.js"
obviously you'll need to get the actual path, and make sure it's got the correct permissions
im using this Color Picker Jquery plugin (http://colpick.com/plugin)
Problem is, i tried same simple code in in .html but when i change just extension to .php, the Color Picker doesnt work, while everything else works.
A simple button and added the important scripts like colpick.js and colpick.css.
Example:
index.html
<html>
<head>
<script src="jquery-2.1.3.min.js"></script>
<script src="canvasSettings.js"></script>
<script src="colpick.js" type="text/javascript"></script>
<link rel="stylesheet" href="colpick.css" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</head>
<body>
<button id="idColor">Show Color Picker</button>
</body>
</html>
canvasSettings.js
$(document).ready(function()
{
alert("First");
$('#idColor').colpick();
alert("Second");
});
So in index.html, when you click on button, it opens the Color Picker and both alert's show up, all good here.
Problem is, when i change index.html to index.php (when using an php server), the site loads up normaly, button shows up and "First" alert shows up.
But when it reaches the $("#idColor").colpick({}) it doesnt process, "Second" alert doesn't show up.
Have in mind that $("idColor").val() works.
Is there any special way to change this .html into .php even tho the html code is the same?
You've misdiagnosed the problem. It has nothing to do with serving up the HTML from PHP instead of a static file.
Here you load jQuery:
<script src="jquery-2.1.3.min.js"></script>
Then you load the plugin which binds itself to jQuery:
<script src="colpick.js" type="text/javascript"></script>
Then you load jQuery again (but a different version):
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
This overwrites the previous jQuery object and the colour picker plugin that you had bound to it.
Decide which version of jQuery you are going to use (the faster 2.x or 1.x with support for old versions of IE).
Load it before you load the plug in (you are currently doing that for 2.x but not 1.x)
Don't load the other version
SOLVED!
The problem was caused by:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
after i removed that, it worked.
Still need to find a bypass around that, why it caused the problem.
I'm new to JavaScript and I'm trying to get a slideshow working in my website. I'm following this tutorial: http://www.queness.com/post/1450/jquery-photo-slide-show-with-slick-caption-tutorial-revisited
Unfortunately it doesn't go into a beginners level of detail as to how to get it installed. I know what I should do with the HTML and the CSS but I'm not sure where I should be putting the JavaScript. Does it go in a separate file or something? How do I get it to work?
Also I'm trying to do this within cakephp so if there's any specific cakey thing I can do that'd be awesome!
Copy all that JavaScript on your referenced page. Save to a new file slide.js or something like that.
Edit your HTML document to include a reference to the jQuery libraby, and that new JavaScript file you've just created:
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script type="text/javascript" src="http://mysite.com/slide.js" />
You can put JavaScript in an external file with a .js extension, and include that in an HTML page using the script tag:
<script type="text/javascript" src="yourscript.js"></script>
Alternatively, you can write the script directly in the script element:
<script type="text/javascript">
//Your script here
</script>
Also note that as the tutorial you are following uses jQuery, you will need to download and include the jQuery library in your page.
The script tags can be placed anywhere in the document, but are usually found inside the head tag, or just before the closing body tag.
Welcome on SO Helen.
That script uses the jQuery library so you have to also include that. http://jquery.com/
JavaScript can best be placed in seperate file with the extension .js
Add the javascript files just before the </body> tag on your page like:
<script src="/js/jquery/jquery-1.4.4.min.js" type="text/javascript"></script>
<script src="/js/jquery/jquery-slideshow2.js" type="text/javascript"></script>
so, I have this webpage here [ http://saikonet.org ] and it's not loading the tipsy script. If you go into the source, it's on line 11. Now, the strange part is all the other scripts are loading fine, and if you click on the tipsy script link, it's loads fine in browser, so syntax and filepath are both fine. even stranger is that is was working completely fine last time I checked.. it just stopped working all the sudden. I'm not sure how to proceed..
(and btw, the way I checked whether it's loading or not was via the script tab in chromium's 'inspect element')
It looks like the tipsy script is being loaded before the jquery file where the former is dependent on the latter.
Change:
<script src="/js/jquery.tipsy.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
to:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="/js/jquery.tipsy.js"></script>
You need to load the jQuery file before you load the tipsy JS file.
In your head section, change this:
<script src="/js/modernizr-1.5.min.js"></script>
<script src="/js/jquery.tipsy.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
To This:
<script src="/js/modernizr-1.5.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="/js/jquery.tipsy.js"></script>
On my Chrome it looks like the tipsy script jquery.tipsy.js is being downloaded.
At any rate, I think you may need to put your tipsy script after your jQuery script.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="/js/jquery.tipsy.js"></script>
I just implemented a multi-language mod onto my website.
Problem is that there seems to be a conflict between the javascript files from the language mod and the javascript files that already were on the page.
<!-- language files here -->
<script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="js/translationEngine.js"></script>
<script type="text/javascript" src="js/jquery.cookie.js"></script>
<script type="text/javascript" src="js/jquery.translate-1.3.9.min.js"></script>
<script>var browserlang = 'en';</script>
<!-- Javascript -->
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="js/jquery.pngFix.pack.js"></script>
<script type="text/javascript" src="js/jquery.flow.1.2.min.js"></script>
<script type="text/javascript" src="js/jquery.prettyPhoto.js"></script>
<script type="text/javascript" src="js/concept.js"></script>
js/jquery-1.3.2.min.js is what makes the 3 image slider on the homepage work, but... it seems to also be interfering with the functions of the translator.
If u remove js/jquery-1.3.2.min.js from the page, the translator works fine, but the slider no longer works.
removing js/jquery-1.4.2.min.js from the page doesnt make the translator work either, in fact it seems to cause more errors in the back.
Can someone guide me in the right direction that would allow me to make the language translator and image slider both work?

Thanks :)
The short version is to remove this:
<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
And update your plugins, there are likely 1.4.x versions out there for each of them. By including jQuery a second time, like you are currently, it'll wipe out plugins and cause all sorts of issues...the first step is removing the second (hopefully the older) instance.
Edit: Here's an updated version of jFlow called jFlow plus that works with 1.4.2.
Check out the jQuery noConflict function. This function tells jQuery to relinquish it's control over the $ variable. This way, other libraries can use it.
The online docs give a pretty good guide as to how to use this function. It saved me a few times.
Example from the online docs:
<script type="text/javascript" src="other_lib.js"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$.noConflict();
jQuery(document).ready(function($) {
// Code that uses jQuery's $ can follow here.
});
// Code that uses other library's $ can follow here.
</script>
Basically, once you call noConflict, you can still use jQuery, just use it using the jQuery variable name instead of $.
Hope this helps!
I have alway solved conflicts between two versions of jquery e.g. jQuery 1.3.2 and jQuery 1.4.2 on the same page using iframes but i recently found out that you can use version jquery-1.5.1.js alone and everything works fine.
I change all the .js file on the page used from below code:
<script>
var K = jQuery.noConflict();
alert(K);
jQuery(document).ready(function () {
alert("Bye");
});
</script>
It works fine now.
I ended up just changing the order in which the libraries loaded.
I let all the jquery libraries load first, from newest to oldest. Then i called for the javascript files that rely on jquery.
It works fine now.
