For some reason the external .js file I am linking to isn't working. I am linking to it like so:
<script src="jquery.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
I have tested jquery using a simple inline script to hide a paragraph of text when it is clicked on so the jquery library is present and working.
The jquery.js file is in the same folder as the index.php file that is calling it.
What am I doing wrong?
This is the code I have in the external .js file currently just to test it is working(it isn't):
$("document").ready(function(){
$("p").click(function(){
$("p").css("color", "red");
});
});
Problem 1
It looks like jquery.js contains the code you wrote that depends on jQuery.
You need to load jQuery before you try to use it.
Swap the order of the <script> elements.
Problem 2
$("document") will wait for <document> elements to be ready. HTML doesn't have such a thing. Lose the quotes to pass in the document object directly.
Better yet, forget about the explicit call to ready and just
jQuery(function () { /* your function */ });

I hava many jsp page using the common function in body's onload and onunload event when using ocx control.So I extract the common function in one js file call common.js and import the js file in the jsp page.But I find the sometimes the jsp page could not execute the function in js file.Finally,I solve the problem in two way but I think there must have the other simple way?How to simplify my js code?
write all the js function in each jsp,it works well
in the each jsp file,includ the common.js,and in the jsp file the script call the function before load the common.js,but I think it have already be loaded two times
//init(),asynclogin_onclick(),logout_onclick() function is in the common.js file
<head>
<script type="text/javascript" src="/js/common.js"></script>
</head>
<body onload="init()" onunload="logout_onclick()">
$(function(){
$.getScript("/js/common.js")
.done(function(script,textStatus ) {
asynclogin_onclick();
});
});
I try to write the code like this,but it could not work.
$(function(){
asynclogin_onclick();
});
I have this code in the footer of my html page
<script type="text/javascript">
// using jQuery
$('video,audio').mediaelementplayer();
</script>
the above code is adding video player on the html page.
Now I have created a separate js file in which I have already have some line of code which is creating owl sliders, tooltips, number counters etc.
When I add the above code into that separate js file it does not work, instead when I keep it in the footer of the html page it works fine.
Try placing your code within $(function(){ ... }. This will execute when the DOM is loaded (currently your code is being executed before jQuery is loaded, if you check the JavaScript console, you will see an error something like $ is not defined)
$(function(){
$('video,audio').mediaelementplayer();
});
or
$( document ).ready(function() {
$('video,audio').mediaelementplayer();
});
You can read about what that is doing here. $(function() is the same as $( document ).ready()
your html(basically) should look like this:
<html>
<head>
</head>
<body>
<!-- html code here -->
<!-- add jquery lib -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- your script -->
<script src="you/file/path.js"></script>
</body>
</html>
and your jquery file:
jQuery(function($) {
// your functions here
$('video,audio').mediaelementplayer();
});
Do you have a proper link to the separate js file in your page, generally at the bottom of the body? It should look something like this:
<script type="text/javascript" src="/joyride_odoo_models/static/js/scripts.js"/>
If you've done that properly, have you tried clearing your browser cache? You may need to do that to detect new javascript files.
How do you call your external js file ?
You must add your references js before your external js file.
you must add your function on document.ready.
You may wait until jQuery is full loaded or ready.
Ex.
$(document).ready(function($) {
// Your code goes here
$('video,audio').mediaelementplayer();
});
This code goes in external js file, then you need to include the file in the HTML
<script type="text/javascript" src="path/to/your/js/file"></script>
I have to use a plugin which bundles js files inside html files (gadgets). For one use case I need to drop and re-instantiate a gadget to run updated code.
So say I have foo.html:
<html>
<head>
<script src="foo.js"></script>
</head>
<body>...</body>
</html>
and foo.js which is the file being injected into my actual document's head:
alert("hello");
Problem is I can only cachebust the html file dynamically and declare my gadget as foo.html?x=123, but the JS file I'm after will still be foo.js so the browser will not re-run it.
Question:
Once a <script> tag is inserted into the document and run, is there any way to run it again without using a module-loader or eval?
Thanks!
You could wrap your code in your <script> tags in a function then call your function. This will allow you to call your code to be called multiple times. Like this:
<script>
function loaded(){
// JavaScript here
}
loaded();
</script>
</body>
I'm learning jQuery, and I'm running into a small problem. jQuery code works when I put it directly in my tags in my HTML, but when I import it from a different file, nothing happens. These are my script tags in HTML:
<script type="text/javascript" src="scripts/jquery-1.10.2.js"></script>
<script type="text/javascript" src="scripts/test.js"></script> <!--This is my jQuery code-->
test.js contains the following code:
$(document).ready(function(){
console.log("Hello");
});
When the page loads, the console is empty. However, when I paste the following code as so, in my html document, everything works fine.
<script>
$(document).ready(function(){
console.log("Hello");
});
</script>
Do you really have a folder named scripts in the folder where your HTML files exist? Otherwise try changing this src="scripts/jquery-1.10.2.js" to probably this: src="/scripts/jquery-1.10.2.js"
You can check by browsing to http://yoururl/scripts/jquery-1.10.2.js, the Jquery code should show up. If it's not there, you have to make sure that you include the right folder/file.
Yes.You will be able to push your scripts in 2 ways::
1-push your scripts in tag like>>
<script>$(document).ready(function(){alert("Welcome Dear");});</script>
2-push your inline scripts with attributes like>>
<button type='button' onclick="$(this).hide()">Hide Me</button>
make sure that the scripts folder contain test.js make sure that the extension is correct ..sometimes I make the same same mistake, instead of test.js i save it as test.js.txt
Try putting
<script type="text/javascript" src="scripts/jquery-1.10.2.js"></script>
in the body rather than the head.

I have some javascript functions added in .js file and also added following Jquery function
$(document).ready(function () {
alert("aj");
$(".QDContactDetails").click(function (event) {
alert("Clicked !!!");
});
});
i wonder that javascript functions call properly but above jquery lines doesn't work.. what is problem in above code? how can i put Jquery in .js file..
i am using newly version of Jquery1.7
What you have should work fine. You just need to ensure that you place the reference to jQuery first, then your own external js file references after that:
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/my-jquery-code.js"></script>
