@if Statement


@if ( condition1 ) ┬á┬á┬á┬á┬á┬átext1 [@elif ( condition2 ) ┬á┬á┬á┬á┬á┬átext2] [@else ┬á┬á┬á┬á┬á┬átext3] @end

condition1, condition2: Optional. An expression that can be coerced into a Boolean expression.

text1: Optional. Text to be parsed if condition1 is true.

text2: Optional. Text to be parsed if condition1 is false and condition2 is true.

text3: Optional. Text to be parsed if both condition1 and condition2 are false.

When you write an @if statement, you do not have to place each clause on a separate line. You can use multiple @elif clauses. However, all @elif clauses must come before an @else clause.

You commonly use the @if statement to determine which text among several options should be used for text output. For example:

┬á	Copy Code
alert(@if (@_win32) "using Windows NT or Windows 95" @else "using Windows 3.1" @end)
