Synopsis
The comma operator. This operator can delimit expressions in the same line of script. It can be used in a number of ways. For example, to declare multiple variables, the syntax would be:
var varName1, varName2, ... varNameN
Multiple script statements may also be joined together on the same line. Therefore, the following script line:
alert("Howdy"),alert("Doody")
presents two alert dialog boxes in sequence (the second one appears
after the first is dismissed by the user). Another application is in
for
loops when you wish to involve two (or more)
variables in the loop:
for (var i = 0, var j = 2; i < 20; i++, j++) { ... }
Example
var isNav, isIE
