javascript - jQuery callback function in callback function -


i want data store in var searchedusers, problem when alert(searchedusers); there nothing in it. if alert(searchedusers); under var user code. there in it.

i assume because code runs before executed. guess have add callback function in there somewhere doesn't seem work errors.

function addfriend() {     var formdata = "name=" + $("#nameform").val() + "&familyname="             + $("#familyname").val() + "&emailaddress="             + $("#emailaddress").val();     var searchedusers = [];     $.ajax({         type : "post",         url : "controllerjavascript?action=addfriend",         datatype : "xml",         data : formdata,         success : function(xml) {             $(xml).find("user").each(                     function() {                         var user = $(this).find("name").text().trim() + " "                                 + $(this).find("familyname").text().trim()                                 + " // " + $(this).find("email").text().trim();                         searchedusers.push(user);                     });          },         error : function() {             alert("an error occurred while processing xml file.");         }     });     alert(searchedusers);     getfriends(); }

is possible add callback function first users pushed searchedusers?

you have function:

success : function(xml) { ... },

this callback. call alert after each method:

success : function(xml) {         $(xml).find("user").each(                 function() {                     var user = $(this).find("name").text().trim() + " "                             + $(this).find("familyname").text().trim()                             + " // " + $(this).find("email").text().trim();                     searchedusers.push(user);          });          alert(searchedusers);     },

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
