I can't understend why variable "s_return" dont work
$('.codeinput').change(function() {
var s_return="";
var to_check=this.value ;
$.ajax({
type: "POST",
url: "check.php",
data: "code="+to_check}).done(function( msg ) {
s_return=msg; // msg - variable work fine
});
// here variable "s_return" is unset
this.value=s_return;
});
I will appreciate any help.
s_return=msg;
is inside an async function. It will be set, when the server responses.
this.value=s_return;
runs right after the request is fired. therefore s_return isn't set, yet.
You will need to do it like this:
$('.codeinput').change(function() {
var that = this;
var s_return="";
var to_check=this.value ;
$.ajax({
type: "POST",
url: "check.php",
data: "code="+to_check
}).done(function( msg ) {
that.value=msg;
});
});
The AJAX call runs asynchronously. If you step through it, you'll see that this.value=s_return; executes before s_return=msg; does, so s_return is still empty when you do the this.value=s_return; assignment.
