When you define a function in a 'for' loop using the loop variable, all
functions will have a *reference* to that variable, not a copy. Example:
for (var i=1;i<=5;i++{
function () {
return i;
}
}
If you captured those inner functions and called them after the loop has
terminated, they would all return 5. Hence your choice using a helpvar is
exactly right. By this you get a *copy* of the current value into your
function.
Other than that, there is nothing to stop you from using a generic event
handler:
label[zeittyp].addListener("mousedown", function (e) {
var lzeittyp = zeittyp;
this.selectedZeittyp.setValue(this.zeittypen[lzeittyp]["title"]);
...
I suggest using a different name for the local variable, though (like
"lzeittyp" in this code snippet).
