# Why Does 1+1 Equal 11? Or How Do I Convert A String To A Number?

Sep 2, 2006

Javascript variables are loosely typed: the conversion between a

## Convert A Number To A String?

Apr 3, 2010

I'm trying to write code to swap images in a list. It's going to be a star rating control that highlights stars as you hover over a star. each image in the list has an onmouseover="highlight(this)" function and a unique id of 1 - 10.

Code:
function highlight(star) {
var num = Number(star.id);
for (i = 0; i < num; i++)

[Code].....

I'm trying to convert the number 'i' used by the for loop to a string so it can be used by the getElementById() method to select the stars to be highlighted. But my intellisense is telling me there is a problem with that line. I tried

var id = String(i+1);

but this didn't work either.

what have I gotten wrong?
