Rusty Javascript

Leave a comment Standard

Today I was having a total brain fart on my javascript abilities. So after some nifty google searching I was able to refresh my memory. If I’ve forgotten I’m sure you will too.

Declare A String

var result = new String(“my text goes in here”);

Substring Function

result.substring(0, 3); //pulls the first 3 characters off the string

Find All Child Field Of A DIV Layer

var children = document.getElementById(“div_id_here”).childNodes;

For Each Loop

for (var i in children) {

Is Numeric Check

if (!isNAN(document.getElementById(“div_id_here”).value))
alert (“This really is a number!”);
