this for loop doesn't look right,

for (var i=0; names_check.length > 1; i++) {

i don't think you're actually setting an ending condition and instead going out of bounds on the array. maybe something like this?

for(var i = 0,  l = names_check.length; i < l; i++){

umm the loop is working fine, only thing is wrong that it gives error in console that actually doesn't effect the code. So the code works but id like it to be error-free. Atm its giving error on this line

if (names_check[i].name == $("#username_reg").val()) {

names_check[i].name // .name part which comes from  var names_check = [{"name" :"example"}];

If it can't find the value of name because check_names is undefined, doesn't that imply that loop is in fact, not working correctly? It would interesting to see what exactly is in names_check and what the value of i is at each iteration. I can't imagine it's a good thing to start a loop but not end it, while also referencing an array at its indexes. You can just log and confirm instead of guessing I suppose....

Yea you was right there was 1 typo in for loop.

for (var i=0; names_check.length > 1; i++) {

Had to be

for (var i=0; names_check.length > i; i++) {

Thx for help.
