What's the best way to break from
nested loops in
Javascript?

//Write the links to
            the page.
for (var x = 0; x < Args.length;
            x++)
{

 for (var Heading in
            Navigation.Headings)
 {
 for (var Item in
            Navigation.Headings[Heading])
 {
 if (Args[x] ==
            Navigation.Headings[Heading][Item].Name)
 {
 document.write("            href=\"" 
 + Navigation.Headings[Heading][Item].URL + "\">" 
 +
            Navigation.Headings[Heading][Item].Name + " : ");
 break; //
            <---HERE, I need to break out of two loops.

 }

            }
 }
}

Answer

Just like
Perl,

loop1:
 for (var i
            in set1) {

loop2:
 for (var j in set2)
            {
loop3:
 for (var k in set3) {
 break loop2; // breaks
            out of loop3 and loop2
 }
 }

            }

as
defined in EMCA-262 section 12.12. href="https://developer.mozilla.org/en/JavaScript/Reference/Statements/label"

Unlike
C, these labels can only be used for href="https://developer.mozilla.org/en/JavaScript/Reference/Statements/continue"
rel="noreferrer">continue and href="https://developer.mozilla.org/en/JavaScript/Reference/Statements/break"
rel="noreferrer">break, as Javascript does not
have goto.
