The Jquery each method jumps out of the loop and obtains the returned value.

This article mainly introduces the Jquery each method to jump out of the loop and obtain the returned value. If you need it, you can refer to it for help.

Return false: stops the loop (like using 'Break' in a normal loop ').

Return true: jump to the next loop (just like using 'contine' in a normal loop ').

The Code is as follows:

Function test (){

Var success = false;

$ (...). Each (function (){

If (..){

Success = true;

Return false;

}

});

Return success;

}

 

Jquery is an object chain, so $ (...). each () returns an object set. Each (function () {}): It is a callback function. In the callback function, results cannot be returned outside the callback function each.
