javascript - When making an ajax call I receive "TypeError: e is undefined" -

i trying display contents of website using file_get_contents in php script , ajax on front-end. can display whole page fine if try display amount of images on page, receive "typeerror: e undefined" error. here php:

<?php     $url= 'https://twitter.com/twitter';     if($url!="")         echo file_get_contents($url); ?> 

here jquery:

    $.ajax({     url : "twitter.php",     datatype: "html",     success : function (data) {         console.log("loaded");         //$(data).appendto('#images');         $.each(data.items, function(i,item) {             $("<img />").attr("src", item.media.m).appendto('#images');             if (i == 5) return false;         });     } }); 

data html string, iterate on (like dom tree) using jq, you'll have call jq constructor (or init method). did when tried append current dom:

  $(data).appendto('#images'); // \==>$() function call, returns jq instance //         when passing markup string, jq parse 

the loop, therefore, should like:

$.each($(data), function(){}); 

and please, try adding in couple of console.log statements, lot when debugging.
