[Javascript] length property?

[Peter Brunone]

Les,

    Do you want to know the value of the number, or the length?  The length
of any string value can be found by the length property, e.g.

var newString = "boo";  // making a string just for fun
var strLength;  // just making a variable to hold the length

    And then...

strLength = newString.length;

    or

strLength = "boo".length;

    or

strLength = document.formName.fieldName.value.length;

    You can use it on any string at all.

Cheers,

Peter
