JQuery method for jumping out of the each loop _ jquery

This article mainly introduces how JQuery jumps out of the each loop. This article explains how jquery jumps out of the current each loop, how the Jqueryeach method jumps out of the loop, and how to obtain the returned value, for more information, see I. jquery each loop to implement the break and continue functions:

Break ---- return false;
Continue -- use return ture;

II. how does jquery jump out of the current each loop?

Some may think that continue and break can be used directly when jquery jumps out of the loop, but they do not work after they are used, because jquery does not have these two commands.

Then I checked it online and got the result:
Return false; -- jump out of all loops; equivalent to the break effect in javascript.
Return true; -- jump out of the current loop and enter the next loop; equivalent to the continue effect in javascript
Example

The code is as follows:

$ (Function (){
$ ("Input [type = 'text']"). each (function (I ){
Var _ val = $ (this). val ();
Alert (_ val );
If (_ val = '2 '){
Return false; // jump out of the loop
}
})
});

III. Jquery each method

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.
