When i use the following syntax, the inline script is not executed. In Firebug not able to debug the code.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js" type="text/javascript" />
<script>
$(document).ready(function () {
$('#btn').bind('click', function () {
alert('hai');
});
});
</script>
but if i change the external file add script, it works fine. no issues at all.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js" type="text/javascript" > </script>
You must close <script> tag.
W3.ORG:
Start tag: required, End tag: required
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js" type="text/javascript"></script>
<script>
$(document).ready(function () {
$('#btn').bind('click', function () {
alert('hai');
});
});
</script>
script is html pair tag. You have to close it
BTW there's no reason to use https
the browser inserts the content from the url provided in the src attribute into the <script></script> tag. so if there is only a emtpy tag you can't insert anything
Your are closing the script tag too early. Remove the last slash from the first row.

I am using jquery for focus of tabs. When i used :
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
in my jsp then the window.load function works good, but when i downloaded jquery.min.js and added in js folder.
<script type="text/javascript" src="jquery.min.js"></script> like this.
Now window.load function is not working.
<script type="text/javascript">
$(window).load(function() {
alert('Hello');
if($("#updatetemp").val()=="TRUE"){
$("#update_link").click();}
});
</script>
I found out the way to use JQuery locally..
jQuery(window).bind("load", function($) {
var msgtemp= jQuery("#updatetemp").val();
if(msgtemp=="TRUE"){
jQuery("#update_link").click(function() {
}).click();
}
});
Instead if $ symbol i just used jQuery attribute and it worked.
i made a html page with this coding
<html>
<head>
<script src="../a.js">
var u=document.URL; var i='t4527878445'; m_web(u,i);
</script>
</head>
<body>
</body>
</html>
In a.js i have this code
function m_web(u,i) {
alert('l');
alert('u');
}
but my webpage is unable to call this function which is coded in an external file. i am not getting any alert with this. i don't know what is problem. plz tell me simple solution for this.
thanx in advance
A single <script> tag can link to an external resource using the src attribute OR contain inline JavaScript code, but it can't do both at the same time. If you specify a src attribute any content between the <script src="foo.js"> tag and the </script> tag is ignored.
Since you want to load the external JS file, and then execute some JavaScript code, you'll need two separate tags to do so:
<script src="../a.js"></script>
<script>
// your code
</script>
plz write your code like below
<script src="../a.js"></script> </script>
//^^^^^^^^^^^^^^^^^^ first close script tag of linked js file
<script type="text/javascript">// then call your inline jscode
var u=document.URL; var i='t4527878445'; m_web(u,i);
</script>
Try
you are not closing script tag
<script src="../a.js"></script>
^//added closing script tag
<script>
var u=document.URL; var i='t4527878445'; m_web(u,i);
</script>
to alert what you pass use
function m_web(u,i) {
alert(i);
alert(u);
}
In head I have:
<script type="text/javascript" src="/categ.js"></script>
In categ.js, I have:
<script type="text/javascript">
var gallery=new sim({
wrapperid: "gallery1"
..................
</script>
In body I have:
<div id="gallery1"></div>
When I load page, the script is not called, because is in extended file. If I paste it directly in head - it's works.
So, How I can call from "body" with some tag the function in categ.js
Try without
<script type="text/javascript">
...
</script>
inside the categ.js file.
Then put:
window.onload = function() {
// the JS code you want to execute
};
in the file. If you use jQuery you can replace this with:
jQuery(document).ready(function() {
// the JS code you want to execute
};
So in case you want to create a new object on page load you execute this code:
var gallery=new sim({
wrapperid: "gallery1",
foo : "bar"
});
You can try calling it with window.onload to ensure it runs on page ready:
window.onload = gallery;
You can check whether your tag is ready for using with your js by calling window.onload or use jquery

It defines a function and calls it on load of document. (Which is the final step of this tutorial)
I tried to put it into a seperate JS file.
Runs correctly only if I call onload both in JS and in HTML.
But not only body onload or only from JS. I guess I am doing something wrong.
So, following works:
<head>
<script src="Scripts/makeWYSIWYG.js" type="text/javascript"/>
<script type="text/javascript">
window.onload = function () {
makeWYSIWYG(document.getElementById('editor'));
};
</script>
</head>
<body onload="makeWYSIWYG(document.getElementById('editor'));">
Why do I need to call the function twice?
I only have the function definition in "Scripts/makeWYSIWYG.js"
function makeWYSIWYG(editor) {
...
return editor;
};
Thanks,
There are no reason to call the function twice. The is enough.
With the first window.onload you could be changing a former function callback assignment (i.e. in a imported script).
The problem was actually the closing tag, "/>", here:
<script src="Scripts/makeWYSIWYG.js" type="text/javascript"/>
I should have written:
<script src="Scripts/makeWYSIWYG.js" type="text/javascript"> </script>
I guess the second script was helping the tag to be closed and making it run...
More info here: Why don't self-closing script tags work?
I'm learning JavaScript for a project, but I am stuck at the very beginning. I boiled it down, to the function in my script not being defined, but as near as I can tell it is defined.
I have a script: "script.js" with the function display result.
function displayResult()
{
document.write("hello world");
}
in the header of index.html I have this line
<script type="text/javascript" href="script.js"></script>
I have this line later
<body onload="displayResult()">
I have no idea why my function will not call. I would appreciate the help.
<script type="text/javascript" href="script.js"></script>
Should be:
<script type="text/javascript" src="script.js"></script>
there is no href attribute to a script block, its included from an external source through the src attribute.
BTW, calling document.write after the document has finished loading will first clear the entire content of the document, then replace it with whatever you pass to the call (in this case, 'hello world', which is not a valid HTML or XML document).
