## 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?

## 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
string and a number happens automatically. Since plus (+) is also
used as in string concatenation, `` &#391;' + 1 '' is equal to `` &#3911;' '': the
String deciding what + does. To overcome this, first convert the
string to a number. For example:

## Convert Value To Integer.

Sep 25, 2007

function calculateGst(exGst) {

//percentage of current gst.
var gst = 10;

var gstAmount = (exGst * (1 / gst));
var gstInc = (exGst + gstAmount)

}

now, the exGst parameter comes from an document.getElemenetById('txtExGst').value in an onclick event.

the problem is this. if 400 is entered at exGst, the gstAmount spits out 40, as it should, but the gstInc spits out 40040...so its treating it like a string rather than a number...

## Convert Input Field Value To Integer?

Mar 3, 2010

This should be simple, but it's not working for me! The relevant code is beneath. This code is on my html page directly under the input field:

input = document.getElementById('hiddenInput');
var inputInt = parseInt(input.value);
if (inputInt != 0) {
setClick(inputInt);
}

(I've tested it to make sure it sees the input object and that it has the correct value. It does call the setClick function appropriately, too.) This code is in a javascript file called in the <head> of the html page:

[Code]...

setClick() and resetAll() work great when I hook setClick() up to a link. When I try to grab the value from the input field, it doesn't even call resetAll(). I've assumed that it's a problem with converting the value to an integer, but I could be wrong. Does anyone have an idea as to what's going on?
