Dynamic HTML: The Definitive Reference

Name

var — NN 2 IE J1 ECMA 1

Synopsis

A keyword that defines the creation of a new variable. Although the keyword is optional for global variables (those not declared or initialized inside a function), it is good form to use this keyword for each new variable. Using the var keyword inside a function makes the variable local to statements inside the function.

You may simply declare one or more variable names, in which case their initial values are null. Or you can also initialize a new variable with a value.

Example

var a, b, c

var myName = "Susan"
