调用外部js文件中的函数

测验php

<div id="widget_dta"></div> 
<script type="text/javascript" src="widget.js"></script>
<script type="text/javascript">
    init_widget(\'john\',\'robert\');

 (function() {

 // Localize jQuery variable
 var jQuery;

 /******** Load jQuery if not present *********/
   if (window.jQuery === undefined || window.jQuery.fn.jquery !== \'1.4.2\') {
var script_tag = document.createElement(\'script\');
script_tag.setAttribute("type","text/javascript");
script_tag.setAttribute("src",
    "https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js");
if (script_tag.readyState) {
  script_tag.onreadystatechange = function () { // For old versions of IE
      if (this.readyState == \'complete\' || this.readyState == \'loaded\') {
          scriptLoadHandler();
      }
  };
} else { // Other browsers
  script_tag.onload = scriptLoadHandler;
}
// Try to find the head, otherwise default to the documentElement
(document.getElementsByTagName("head")[0] ||   document.documentElement).appendChild(script_tag);
} else {
// The jQuery version on the window is the one we want to use
jQuery = window.jQuery;
main();
}

/******** Called once jQuery has loaded ******/
function scriptLoadHandler() {
// Restore $ and window.jQuery to their previous values and store the
// new jQuery in our local jQuery variable
jQuery = window.jQuery.noConflict(true);
// Call our main function
main(); 
}

/******** Our main function ********/
function main() { 
  jQuery(document).ready(function($) {
     function init_widget(fname,lname) {
        $(\'#widget_dta\').append(\'<p class="fname">first name :\'+fname+\'</p><p class="lname">last name :\'+lname+\'</p>\');
   }
}); 
 }

 })();

错误：我收到此错误“ReferenceError：未定义init\\u小部件”。我做错了什么，谁能帮忙。

/******** Our main function ********/ function main() { window.myutils = window.myutils || {}; //Create a little namespace for your own functions so that they are not all global. //We dont need the jQuery on ready block here. You should assume that whoever calls init_widget will wait for the page to be ready first before calling. window.myutils.init_widget = function(fname,lname) { var $ = jQuery; //convenience so we can still use $ here instead of writing out jQuery all the time. $(\'#widget_dta\').append(\'<p class="fname">first name :\'+fname+\'</p><p class="lname">last name :\'+lname+\'</p>\'); }; }

<div id="widget_dta"></div> <script type="text/javascript" src="widget.js"></script> <script type="text/javascript"> jQuery(document).ready(function($) { window.myutils.init_widget(\'john\',\'robert\'); }); </script>
