Folks,
This is very basic, but I still cannot get it...
I have this js function in an ASP page:
i don't understand the function, as it was put in automatically by dreamweaver. right now, i am using this onclick event of an image:
the #FFFF00 is the color YELLOW. it is being passed to the theValue argument of the js. what i simply want to do is establish a global variable that will house a color string (like #FFFF00), and then use it in the function argument everytime i need the function. something like this:
i do not know how to do two things:
1) initialize and assign the variable a value, and where to establish it (inside the script tags? in the head? in the body?)
2) how to use the variable as an argument in the function
any help greatly appreciated for this novice. thanks!

Code:
function MM_changeProp(objId,x,theProp,theValue) { //v9.0
var obj = null; with (document){ if (getElementById)
obj = getElementById(objId); }
if (obj){
if (theValue == true || theValue == false)
eval("obj.style."+theProp+"="+theValue);
else eval("obj.style."+theProp+"='"+theValue+"'");
}
}
Code:
<div id="apDiv19" onclick="MM_changeProp('apDiv7','','backgroundColor','[COLOR="Red"][B]#FFFF00[/B][/COLOR]','DIV')"></div>

<div id="apDiv19" onclick="MM_changeProp('apDiv7','','backgroundColor',[B][COLOR="Red"]VARIABLE[/COLOR][/B],'DIV')">1) initialize and assign the variable a value, and where to establish it (inside the script tags? in the head? in the body?)
