[Konrad Mathieu]

How do I - within in a function - make Javascript recognize a string as a
variable name?

Thanks and cheers,
Konrad

<script>
var a="blah"
var blah="bloob"
var blib="bloobbloo b"

function f(){
alert(window[a])
alert(window["blib"])
}

f() // alerts: bloob, bloobbloob

</script>

How you do that depends on what the string's variable representation
represents.

For the most part, you simply use bracket notation.

If the string points at a variable, window['StringHere'] will give you a
reference to global variables (there are some cavaets to it I believe).

If its a name of a form element:

document.forms[varName].elements[varName2].propertyName
