Javascript works inline but not in a file
Question
I am new to javascript and am assuming that the answer is simple and right under my nose, but I can't seem to find the proverbial dog that's going to bite me.
Anyway, this works inline:
<script language="javascript">
function foo(){
alert("BOO!")
}
</script>
<body onload=foo()>...
But if I do:
<script type="text\javascript" scr="js/blah.js">
</script>
<body onload=foo()>
blah.js contains:
function foo(){
alert("BOO!")
}
That doesn't work.
Why?

正确的语法是：
<body onload="foo();">

The type is text/javascript ( / instead of \\ ), and the onload attribute in the body element should be onload="foo();" .
Also, is your blah.js file stored inside a directory called js?

Inside markup you can call JavaScript functions. There is nothing wrong with it. This creates a new anonymous function in the DOM tree and adds the value of the Event model as the function body.
<script type="text\javascript" scr="js/blah.js"> </script>
should be
<script type="text/javascript" src="js/blah.js"> </script> // / and src
should be
<body onload="foo()"> // Markup attribute values should be passed inside quotes

所有属性值都必须以“开头”，并以“结尾”
