如何在网页中显示从服务器（使用ajax和jquery）检索到的js文件的内容？

Question

Well I am trying to load and execute a js file using the following jquery function

$.getScript(url, function( data, textStatus, jqxhr ) {
  console.log( textStatus );              // Success
  console.log( jqxhr.responseText );      // 200
  console.log( data);
  console.log( "Load was performed." );
});

Well the requirement for me is to display the contents of js retrieved from server in my webpage. How do I do it?

Does this not work?

<textarea id="ta" style="border:0;"></textarea>

$.getScript( url, function( data, textStatus, jqxhr ) {
         $("#ta").val(data);
});

You can use phpjs's file_get_contents function to get the content of a javascript file
