Подскажите, пожалуйста, как можно выйти из двойного цикла. Пробовал так и ничего не получилось:

function search_Array(point) {
 for (var i = 0; i < mainArray.length; i++) {
 alert(i);
 for (var j = 0; j < mainArray[i].option.length; j++) {
 alert(j);
 if (mainArray[i].option[j].value == point) {
 alert (mainArray[i].option[j].value);
 break endLoop;
 }
 }
 }
 endLoop:
 return [i, j];
}

Можно, конечно, по окончанию первого цикла еще раз вставить такую же проверку (if (mainArray.option[j].value == point) ), но как-то криво выглядит. Помогите. Спасибо.

return вместо break поставь.

endLoop - это что?

Да вот пример похожий из сети вытащил:

The keyword break exits out of loop structures and switch statement.

When a label is used, JavaScript completely breaks out of the area designated by label.

To label a statement, place the label name followed by a colon (:).

Labels are useful when working with nested loops.

 <html>
 <SCRIPT LANGUAGE='JavaScript'>
 <!--
 forLoop1:
 for (var counter1 = 1; counter1 <= 5; counter1++)
 {
 for (var counter2 = 1; counter2 <= 5; counter2++)
 {
 document.write("Counter1=",counter1);
 document.write(" Counter2=",counter2,"<BR>");
 if (counter2 == 3)
 break;
 if (counter1 == 3)
 break forLoop1;
 }
 }
 document.write("All done!");
 //-->
 </SCRIPT>
</html>
