while Statement (Windows Scripting - JScript)

  • Article

 

Executes a statement until a specified condition is false.

Syntax

while (expression)
   statements 

Arguments

  • expression
    Required. A Boolean expression checked before each iteration of the loop. If expression is true, the loop is executed. If expression is false, the loop is terminated.

  • statements
    Optional. One or more statements to be executed if expression is true.

Remarks

The while statement checks expression before a loop is first executed. If expression is false at this time, the loop is never executed.

The following example illustrates the use of the while statement.

function BreakTest(breakpoint){
   var i = 0;
   while (i < 100)
   {
      if (i == breakpoint)
         break;
      i++;
   }
   return(i);
}
