The break statement is used to terminate the current loop, or if in conjunction with a label, terminates the associated statement.
Syntax
break [label];
The optional label argument specifies the label of the statement you are breaking from.
Example
You typically use the break statement in switch statements and while, for, for...in, or do...while loops. You most commonly use the label argument in switch statements, but it can be used in any statement, whether simple or compound.
Executing the break statement exits from the current loop or statement, and begins script execution with the statement immediately following.
The following example illustrates the use of the break statement:
function BreakTest(breakpoint)
{
var i = 0;
while (i < 100)
{
if (i == breakpoint)
break;
i++;
}
return(i);
}
document.write(prompt("Please enter a number between 0 and 100: ","10"));
