Javascript variable scope

Hi, guys

How can I change the global varaible's value in a function

like

<script language="JavaScript">
var color_bg;
function changeBgColor(color)
{
color_bg= color;

window.location.reload();

}

</script>

That's what you are doing here? You've defined color_bg globally and then changed it?

the scope of color_bg = color is limited to the function in this case. You'd have to redefine the value associated with the var color_bg outside of the function in order for its value to be changed globally.

umm... he did that.
but once the command window.location.reload(); is executed, the window is being... (surprise!) reloaded and the variable lose its value.

you don't have, can't have, something like session variables in client side code!!
