Javascript continue/break

Labeled Statements

You can label statements for later use with the following syntax:

label: statement

The following code adds a label for the for loop.

var count = 10;
start: for (var i=0; i < count; i++) { 
   document.writeln(i); 
}

break

The break statement breaks out of the loop, forcing execution to continue with the next statement after the loop.


var num = 0; 
for (var i=1; i < 10; i++) { 
    if (i % 5 == 0) { 
        break; 
    } 
    num++; 
} 
console.log(num); //4

The code above generates the following result.

Example

breaks to outer most loop


var num = 0; 
outermost: /*ww  w. java  2s  .  c o  m*/
for (var i=0; i < 10; i++) { 
    for (var j=0; j < 10; j++) { 
        if (i == 5 && j == 5) {
            break outermost; 
        } 
        num++;
    } 
} 
console.log(num); //55

The code above generates the following result.

continue

The continue statement exits the current loop and continues from the top of the loop.


var num = 0; 
for (var i=1; i < 10; i++) { 
    if (i % 5 == 0) {
       continue;
    } 
    num++; 
} 
console.log(num); //8

The code above generates the following result.

Example 2

continue to outer most level:


var num = 0; 
outermost: //from   ww w.  ja  va2  s . c om
for (var i=0; i < 10; i++) { 
    for (var j=0; j < 10; j++) { 
        if (i == 5 && j == 5) {
             continue outermost;
        } 
        num++; 
    } 
} 
console.log(num); //95

The code above generates the following result.
