I have some code:
$(xml).find("strengths").each(function() {
//Code
//How can i escape from this block based on a condition.
});
How can i escape from the "each" code block based on a condition?
What if we have something like this:
$(xml).find("strengths").each(function() {
$(this).each(function() {
//I want to break out from both each loops at the same time.
});
});
Is it possible to break out from both "each" functions from the inner "each" function?

If you want to continue instead of break out
return true;
This question is related to
javascript
jquery
According to the documentation you can simply return false; to break:
$(xml).find("strengths").each(function() {
if (iWantToBreak)
return false;
});
if (condition){ // where condition evaluates to true
return false
}
see similar question asked 3 days ago.
Return false from the anonymous function:
$(xml).find("strengths").each(function() {
// Code
// To escape from this block based on a condition:
if (something) return false;
});
From the documentation of the each method:
Returning 'false' from within the each function completely stops the loop through all of the elements (this is like using a 'break' with a normal loop). Returning 'true' from within the loop skips to the next iteration (this is like using a 'continue' with a normal loop).
You can use return false;
