i changed code sync type ajax post request , check output. not changed. here code

function submit() {     var outputfromajax = submitviapost('administrator/validationforinputvaluesofaddrole');      console.log(outputfromajax); }  function submitviapost(url) {      var formdata = $('form').serializearray();      var output;      $.ajax({         url: urlforphp + '/' + url,         data: formdata,         datatype: 'json',         async: false,         method: 'post',         success: function (e) {             output =  e;         }     });     return output; }

you can use deferred jquery

function submit() {     submitviapost('administrator/validationforinputvaluesofaddrole').then(function (outputfromajax) {         console.log(outputfromajax);     }); }  function submitviapost(url) {     var dfd = jquery.deferred();     var formdata = $('form').serializearray();     $.post(urlforphp + '/' + url, formdata, function (outputdata) {         dfd.resolve(outputdata);;     });     return dfd; }

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.
