TanGuy,
Thanks, I think that first link helped a lot. I see what the guy is saying
(and I forgot that var's all get moved up to the highest scope - its sad
that I used to aide a web-dev class).
So now, I have something that works in terms of passing around variables
that make sense:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Javascript Dynamic Variables</title>
<script type="text/javascript">
function TestClass( strName ){
this.Name = strName;
}
TestClass.prototype.AlertValue = function( anyValue ){
alert( this.Name + " is alerting: " + anyValue );
}
function Init(){
var objContentDiv = document.getElementById( "content" );
var objA = null;
var objTest = new TestClass( "Tester" );
// This runs the for loop using a LOCAL scope for each iteration.
(function loop( intI ){
var intX = intI;
if (intI < 10){
// Create new A element.
objA = document.createElement( "a" );
// Set A display properties.
objA.style.display = "block";
objA.style.backgroundColor = "#F8F8F8";
objA.style.border = "1px solid #333333";
objA.style.padding = "10px 10px 10px 10px";
objA.style.color = "#333333";
objA.style.marginBottom = "15px";
// Create text for the link.
objA.appendChild( document.createTextNode( "I should alert " +
intX + " when clicked" ) );
// Set the href.
objA.setAttribute( "href", "##" );
// Set the onclick method.
objA.onclick = function(){ objTest.AlertValue( intX ) };
// Attach the A to the content.
objContentDiv.appendChild( objA );
loop(intI + 1);
}
})(0);
}
// Is the tester class available here (just testing).
alert( "objTest is of type: " + typeof(objTest));
</script>
</head>
<body onload="Init();">
<div id="content"></div>
</body>
</html>
Thanks for everyone's help. I think I now see the local scoping issue that I
was dealing with before. I will try to return with a better example.
