Code:

$(function(){

    var str = ABC(ID);  // str = strReturn

});

function ABC(ID) {

  $.get('/u' + ID + '/profile?mode=editprofile&page_profil=friendsfoes', function (e) {

      var strReturn;

      // do somthing here and strReturn has some value
      // return strReturn
      // e.g strReturn = "123"
     
      strReturn = "123";
     
      return(strReturn);  // does not work
  })
}


How do I get the return value ??

It would help if you exactly explain what this script does?

Code:


function ABC(ID) {
 
  $.get('/u' + ID + '/profile?mode=editprofile&page_profil=friendsfoes', function (e) {
 
      var strReturn = $('.panel:eq(4)', e).html();
 
    typeof  strReturn !== "undefined" && (document.body.insertAdjacentHTML('afterbegin', strReturn));
  })
}


if you want some element of friend page, you need set it in a var search in ajax dom and you can insert this element werever you want

with

Code: ABC(1)

or any other id

Thanks Ch@lo Valdez

I try my own ID first but it returns "undefined"

What kind of data you try to return?

just a string, I test

Code:

var str = ABC(ID);

it returns "undefined"

what kind of string? is important you write here your complete idea, otherwise no one can help

just get the foes list from current login user , not others

the function ABC get the foes list , I can do that part and return that value back to main function

This is my sample , just ignore line 18-65 , only string manipulation, the final string on line 67 and good but failed to return value to main function on line 70

Code:

$(function(){
     
    // guest login, just exit
      if (! (_userdata.session_logged_in)) return;

      var uID = _userdata.user_id ;
      var foesstring = getFoesList(uID);
      window.console && console.log("!" + foesstring);

});

function getFoesList(uID) {



  $.get('/u' + uID + '/profile?mode=editprofile&page_profil=friendsfoes', function (e) {
     
    var n1, n2;
    n2 = e.indexOf('>Foes list<');
    n1 = e.indexOf('>Friends list<');
    var strFoes = e.substr(n2);
    var strFriends = e.substr(n1, n2 - n1);

    var n = 0;
    var nEnd = 0;
    var Friends = "";
    var FriendsID = "";

    while (n >= 0) {
      n= strFriends.indexOf('friends-foes-list');
      if (n >= 0) {
        strFriends = strFriends.substr(n+30);
        nEnd = strFriends.indexOf('">') ;
        FriendsID = FriendsID + "," +  strFriends.substr(0,nEnd);

        strFriends = strFriends.substr(nEnd+2);
        nEnd = strFriends.indexOf('</a>') ;
        Friends = Friends + "," +  strFriends.substr(0,nEnd);
      }
    }

    FriendsID = FriendsID.substr(1);
    Friends = Friends.substr(1);

    n = 0 ;
    nEnd = 0;
    var Foes = "";
    var FoesID = "";
     
    while (n >= 0) {
      n= strFoes.indexOf('friends-foes-list');
      if (n >= 0) {
        strFoes = strFoes.substr(n+30);
        nEnd = strFoes.indexOf('">') ;
        FoesID = FoesID + "," +  strFoes.substr(0,nEnd);

        strFoes= strFoes.substr(nEnd+2);
        nEnd = strFoes.indexOf('</a>') ;
        Foes = Foes + "," +  strFoes.substr(0,nEnd);
      }
    }

    FoesID = FoesID.substr(1);
    Foes = Foes.substr(1);

    // It 's OK until here, get all foes ID
    window.console && console.log(FoesID);

    // Return failed and get undefined
    return FoesID;

  });
   
}

ok try this i think inside of get ajax you can't return string or maybe i dont know how lol

but look this:

Code:


$(function(){
    // guest login, just exit
    if (! (_userdata.session_logged_in)) return;
    var uID = _userdata.user_id ;
    var foesstring = getFoesList(uID);
    window.console && console.log("!" + foesstring);
});
function getFoesList(uID) {
    $.get('/u' + uID + '/profile?mode=editprofile&page_profil=friendsfoes', function (e) {
        var n1, n2;
        n2 = e.indexOf('>Foes list<');
        n1 = e.indexOf('>Friends list<');
        var strFoes = e.substr(n2);
        var strFriends = e.substr(n1, n2 - n1);
        var n = 0;
        var nEnd = 0;
        var Friends = "";
        var FriendsID = "";
        while (n >= 0) {
            n= strFriends.indexOf('friends-foes-list');
            if (n >= 0) {
                strFriends = strFriends.substr(n+30);
                nEnd = strFriends.indexOf('">') ;
                FriendsID = FriendsID + "," +  strFriends.substr(0,nEnd);
                strFriends = strFriends.substr(nEnd+2);
                nEnd = strFriends.indexOf('</a>') ;
                Friends = Friends + "," +  strFriends.substr(0,nEnd);
            }
        }
        FriendsID = FriendsID.substr(1);
        Friends = Friends.substr(1);
        n = 0 ;
        nEnd = 0;
        var Foes = "";
        var FoesID = "";
        while (n >= 0) {
            n= strFoes.indexOf('friends-foes-list');
            if (n >= 0) {
                strFoes = strFoes.substr(n+30);
                nEnd = strFoes.indexOf('">') ;
                FoesID = FoesID + "," +  strFoes.substr(0,nEnd);
                strFoes= strFoes.substr(nEnd+2);
                nEnd = strFoes.indexOf('</a>') ;
                Foes = Foes + "," +  strFoes.substr(0,nEnd);
            }
        }
        FoesID = FoesID.substr(1);
        Foes = Foes.substr(1);
        // It 's OK until here, get all foes ID
        window.console && console.log(FoesID);
        // inside of $.get function maybe is better storage the data in cookie or window.storage and call in another function, just try it
        my_setcookie('friendsid'+uID, FoesID);
        return_friends(uID)
    });
}
function return_friends(c){
    return my_setcookie('friendsid'+c);
}
//use return_friends(id) example: document.body.innerHTML = return_friends(_userdata.user_id)


mmm or just use a universal variable

Code:


$(function(){
    // guest login, just exit
    if (! (_userdata.session_logged_in)) return;
    var uID = _userdata.user_id ;
    var foesstring = getFoesList(uID);
    window.console && console.log("!" + foesstring);
});
function getFoesList(uID) {
    $.get('/u' + uID + '/profile?mode=editprofile&page_profil=friendsfoes', function (e) {
        var n1, n2;
        n2 = e.indexOf('>Foes list<');
        n1 = e.indexOf('>Friends list<');
        var strFoes = e.substr(n2);
        var strFriends = e.substr(n1, n2 - n1);
        var n = 0;
        var nEnd = 0;
        var Friends = "";
        var FriendsID = "";
        while (n >= 0) {
            n= strFriends.indexOf('friends-foes-list');
            if (n >= 0) {
                strFriends = strFriends.substr(n+30);
                nEnd = strFriends.indexOf('">') ;
                FriendsID = FriendsID + "," +  strFriends.substr(0,nEnd);
                strFriends = strFriends.substr(nEnd+2);
                nEnd = strFriends.indexOf('</a>') ;
                Friends = Friends + "," +  strFriends.substr(0,nEnd);
            }
        }
        FriendsID = FriendsID.substr(1);
        Friends = Friends.substr(1);
        n = 0 ;
        nEnd = 0;
        var Foes = "";
        var FoesID = "";
        while (n >= 0) {
            n= strFoes.indexOf('friends-foes-list');
            if (n >= 0) {
                strFoes = strFoes.substr(n+30);
                nEnd = strFoes.indexOf('">') ;
                FoesID = FoesID + "," +  strFoes.substr(0,nEnd);
                strFoes= strFoes.substr(nEnd+2);
                nEnd = strFoes.indexOf('</a>') ;
                Foes = Foes + "," +  strFoes.substr(0,nEnd);
            }
        }
        FoesID = FoesID.substr(1);
        Foes = Foes.substr(1);
        // It 's OK until here, get all foes ID
        window.console && console.log(FoesID);
     
      foesID = FoesID;
     
    });
}




just use

Code: foesID

and return string

or this way:

Code:



$(function(){
    // guest login, just exit
    if (! (_userdata.session_logged_in)) return;
    var uID = _userdata.user_id ;
    var foesstring = getFoesList(uID);
    window.console && console.log("!" + foesstring);
});
function getFoesList(uID) {
var foesID; // <----- new var
    $.get('/u' + uID + '/profile?mode=editprofile&page_profil=friendsfoes', function (e) {
        var n1, n2;
        n2 = e.indexOf('>Foes list<');
        n1 = e.indexOf('>Friends list<');
        var strFoes = e.substr(n2);
        var strFriends = e.substr(n1, n2 - n1);
        var n = 0;
        var nEnd = 0;
        var Friends = "";
        var FriendsID = "";
        while (n >= 0) {
            n= strFriends.indexOf('friends-foes-list');
            if (n >= 0) {
                strFriends = strFriends.substr(n+30);
                nEnd = strFriends.indexOf('">') ;
                FriendsID = FriendsID + "," +  strFriends.substr(0,nEnd);
                strFriends = strFriends.substr(nEnd+2);
                nEnd = strFriends.indexOf('</a>') ;
                Friends = Friends + "," +  strFriends.substr(0,nEnd);
            }
        }
        FriendsID = FriendsID.substr(1);
        Friends = Friends.substr(1);
        n = 0 ;
        nEnd = 0;
        var Foes = "";
        var FoesID = "";
        while (n >= 0) {
            n= strFoes.indexOf('friends-foes-list');
            if (n >= 0) {
                strFoes = strFoes.substr(n+30);
                nEnd = strFoes.indexOf('">') ;
                FoesID = FoesID + "," +  strFoes.substr(0,nEnd);
                strFoes= strFoes.substr(nEnd+2);
                nEnd = strFoes.indexOf('</a>') ;
                Foes = Foes + "," +  strFoes.substr(0,nEnd);
            }
        }
        FoesID = FoesID.substr(1);
        Foes = Foes.substr(1);
     
      foesID = FoesID;
     
    });
    return foesID //return after ajax request
}




but still use

Code:  foesID

to return string

ok after read a lot of pages this is how, i think

Code:


function getFoesList(uID) {
    var B, A = $.ajax({
        type: "GET",
        url: '/u' + uID + '/profile?mode=editprofile&page_profil=friendsfoes',
        async: false,
        cache: false,
        type: "get",
        dataType: "text",
        success: function (response, status, xhr) {
            if (xhr.status == 200) {
                var n2 = response.indexOf('>Foes list<'),
                    n1 = response.indexOf('>Friends list<'),
                    strFoes = response.substr(n2),
                    strFriends = response.substr(n1, n2 - n1),
                    n = 0,
                    nEnd = 0,
                    Friends = "",
                    FriendsID = "";
                while (n >= 0) {
                    n = strFriends.indexOf('friends-foes-list');
                    if (n >= 0) {
                        strFriends = strFriends.substr(n + 30);
                        nEnd = strFriends.indexOf('">');
                        FriendsID = FriendsID + "," + strFriends.substr(0, nEnd);
                        strFriends = strFriends.substr(nEnd + 2);
                        nEnd = strFriends.indexOf('</a>');
                        Friends = Friends + "," + strFriends.substr(0, nEnd);
                    }
                }
                FriendsID = FriendsID.substr(1);
                Friends = Friends.substr(1);
                n = 0;
                nEnd = 0;
                var Foes = "";
                var FoesID = "";
                while (n >= 0) {
                    n = strFoes.indexOf('friends-foes-list');
                    if (n >= 0) {
                        strFoes = strFoes.substr(n + 30);
                        nEnd = strFoes.indexOf('">');
                        FoesID = FoesID + "," + strFoes.substr(0, nEnd);
                        strFoes = strFoes.substr(nEnd + 2);
                        nEnd = strFoes.indexOf('</a>');
                        Foes = Foes + "," + strFoes.substr(0, nEnd);
                    }
                }
                FoesID = FoesID.substr(1);
                Foes = Foes.substr(1);
                B = FriendsID; // or FoesID
            }
        }
    });
    return B
}


call with

Code: getFoesList(_userdata.user_id);

$.get is a shorthand of $.ajax, but by default asinc mode is true, and we need asinc in false mode

Thank You very much , Ch@lo Valdez

You are the best ...
