How to define a global variable in HTML file?

amit

Hello Group,

Does anybody know how I can have a global variable in an HTML file? for
instance, I have a fuction (called aFunction() here) and during a
mousedown or up event the function is going to be called.

The third passing arugment or parameter is myGlobarVar. How can I make
this work? since myGlobalVar is defined in a different block of
javascript within the HTML file?
<html>

<head>

<title>testin g an HTML for global variable!</title>

<script type="text/javascript" src="myfile.js" >
var myGlobalVar = "S100";
aFunction();
</script>

</head<body>

My IMAGE
<img onmousedown= "javascript:aFu nction(ev, this, myGlobalVar);"
onmouseup="java script:aFunctio n(ev,this);" src="MyImage.gi f" border=0

>

</body>

</html>
Thanks in advance.
Amit.

Now it is working! my problem was that I was mixing the include
javascript file statement and the variable together in one single
block. When I separate them it works just fine. Thanks anyway.

wrong way:

<script type="text/javascript" src="myfile.js" >
var myGlobalVar = "S100";
aFunction();
</script>
corrected:

<script type="text/javascript" src="myfile.js" >
</script>

<script type="text/javascript" src="myfile.js" >
var myGlobalVar = "S100";
</script>

After optimization, global variables might be misaligned because each global variables must be converted to 32 bits, but I do see that C/C++ Compiler do padding between variables. Struct does the same to do padding....
