Microsoft® JScript for Statement |
| Language Reference |
|
Executes a block of statements for as long as a specified condition is true.
for ( initialization; test ; increment )
statementThe for statement syntax has these parts:
Part Description initialization An expression. This expression is only executed once, before the loop is executed.
test A Boolean expression. If test is true, statement is executed. If test if false, the loop is terminated. increment An expression. The increment expression is executed at the end of every pass through the loop. statement The statement to be executed if test is true. Can be a compound statement.
You usually use for loops when a loop is to be executed a specific number of times. For example:for (i = 0; i < 10; i++) // i is set to 0 at start, and incremented { // by 1 at end of each iteration. Loop terminates j *= i; // when i is not less than 10 before a loop iteration. }
