Scope of JavaScript and ajax

Var sort = 0;

Function createHidden (){

Var htm = "<input type = 'den den 'id = 'H _" + sort + "'/> ";

$ ("# Id"). append (htm );

$. Get ("xxx. aspx", function (data ){

// 1. Callback data = 1234

$ ("# H _" + sort). val (data );

Alert ($ ("# h _" + sort). val (); // enter understand

});

Sort ++;

}

Explanation:

Because the value of sort has changed during asynchronous processing. When it comes to asynchronous processing, the program still needs to go down. Therefore, first give sort ++; to the end $ ("# h _" + sort ). when val () is actually $ ("# h_1 "). val (); because no system can find this id, it is assumed that it is understand.
