html - createElement and appendChild in JavaScript -

-

i trying figure out why createelement , appendchild aren't working. believe i've got code correct i'm not sure why it's not working... (i using ie 10)

code updated

javascript file:

var myobj = {     firstname: "john",    lastname: "smith" };

html file: 

<!doctype html /> <html> <title>the data structure</title> <body>  <script type="text/javascript" src="thedata.js">  var theelement = document.createelement('p'); var thetext = document.createtextnode(myobj.firstname); theelement.appendchild(thetext); document.body.appendchild(theelement);  </script> </body> </html>

the issue both supply src on script tag and provide content within it. that's invalid, can 1 or other, not both. browsers use src , disregard content.

separate that, creating element doesn't put in dom. have add somewhere (via appendchild or insertbefore or similar).

so perhaps:

<script src="thedata.js"></script> <!-- note: 2 separate script elements --> <script> var theelement = document.createelement('p'); var thetext = document.createtextnode(myobj.firstname); theelement.appendchild(thetext); document.body.appendchild(theelement); // <==== note: adding `the element` dom </script>
