为什么 Jquery tokeninput 值为空？

Question

我用过http://loopj.com/jquery-tokeninput/分词器。数组值始终为空。这是我的代码。任何人都可以告诉我的代码有什么问题吗？

<div>
    <input type="text" id="first" name="first" onchange="callthis()"/>

    <script type="text/javascript">
    $(document).ready(function() {
        $("#first").tokenInput([
            {name: "Ruby"},
            {name: "Python"},
            {name: "JavaScript"},
            {name: "ActionScript"},
            {name: "Scheme"},
            {name: "Lisap"},
            {name: "C#a"},
            {name: "Fortran"},
            {name: "Visual Basic"},
            {name: "Ca"},
            {name: "C++"},
            {name: "Java"}
        ]);
    });
    </script>
</div>

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript" src="src/jquery.tokeninput.js"></script>
<link rel="stylesheet" href="styles/token-input.css" type="text/css" />

<script>
  function callthis(){
    var val = $('#first').tokenInput("get");
    alert(val);
  }
</script>

在他们的文档中，他们要求使用这一行来获取值。selector.tokenInput("get");提前致谢。

我刚刚尝试使用以下代码：

 $("#first").tokenInput([
    {name: "Ruby"},
    {name: "Python"},
    {name: "JavaScript"},
    {name: "ActionScript"},
    {name: "Scheme"},
    {name: "Lisap"},
    {name: "C#a"},
    {name: "Fortran"},
    {name: "Visual Basic"},
    {name: "Ca"},
    {name: "C++"},
    {name: "Java"}
 ]);

  $("#first").change(function(){
     var val = $('#first').tokenInput("get");
  });

它工作正常。请参阅此示例 http://jsfiddle.net/L4oth1d8/3/
