javascript - Script load on xhr response -

i have problem responsetext. want load script includes/dodaj-slike.php (which echo)

xhr.onreadystatechange = function(e) {     if(this.readystate === 4) {         alert(xhr.responsetext);     } };  xhr.open('post', 'includes/dodaj-slike.php', true); xhr.send(formdata); 

alert responsetext (example) :

<script type='text/javascript'>     $('ul li:nth(0)').append('<img src='uploads/cropped_2013-08-12 00.50.37.jpg'/>'); </script>  <script type='text/javascript'>     $('ul li:nth(1)').append('<img src='uploads/cropped_2013-08-18 12.56.24.jpg'/>'); </script> 

i , want somehow load script after response.

my question how load script on way?

you can with

document.head.appendchild(responsetext); 

correct way suggested

$("head").append(xhr.responsetext);
