Hello everybody.
I'm starting to use prototype framework and i'm having a problem.
I have an ajax javascript function that checks if the user is logged.
This function uses coldfusion's native ajax.
The code
function userLogged(){
var $userLogin = new objUser(); //objUser is a coldfusion component
var result = $userLogin.getUserLoginStatus(); //getUserLoginStatus is
a method
return result;
}
function checkLogged(){
var logged = userLogged();
if(logged == true)
alert('logged');
else
alert('not logged');
}
But i need to replace this to one written with prototype. I tried the
code down (the return of cfm script is a JSON).
function userLogged(){
var logged = false;
new Ajax.Request('/includes/GetUserLoginStatus.cfm', {
method: 'get',
onSuccess: function(r) {
var response = r.responseText.evalJSON();
var logged = response.STATUS;
}
});
return logged;
}
When i call this function the return always false. Obviously because
onsuccess create another function and it doesn't change the value of
external variable.
I'm asking for you guys if there's some way to change the value of
variable logged based on the return of the ajax call? Or there's a way
inside onSuccess to return the response to the caller function?
Thanks for the attention and sorry for my english.
Regards, Ian
