javascript dynamic function problem

[chathura86]

			for (i = 0; i <= 30; i++)
			{
				var obj = 'date_' + i;
				document.getElementById(obj).onmouseover = function (event) { alert(i) };
			}

date_1, date_2, date_3, ........., date_30 are hyperlink with those ids

i have added the above javascript to show the date on mouse over but no matter which date I go mouse over, it shows 30, and when i set i <= 10 it shows 10
i think it shows the final value of i,

please help me to fix it.

what happened here is (in my opinion) that you incidentally run into a Closure. (this happens when you define a function inside another function or if events are incorporated) the interesting point is, that local variables (here i) are preserved.

Thanks for the responce

any idea how to fix it?

e.g.

element.parameter = i;
element.onmouseover = function() { alert(this.parameter); }

some more advanced one

element.parameter = i;
var show = function() { alert(this.parameter); }
element.addEventListener("mouseover", show, false);
// or use the appropriate cross-browser solution
