javascript 包含在内，因为 php 不工作

Question

我正在尝试包含一个标签函数，就像我们在 stackoverflow 中一样。当我输入标签并按 Enter 键时，文本输入内会形成一个漂亮的标签。我的问题是当 javascript/html php 页面单独加载时它可以工作。但是当我在我的主页中包含这个 php 时，它不起作用。这是我的 tag.php 页面

<link rel="stylesheet" type="text/css" href="./src/jquery.tagsinput.css" />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script type="text/javascript" src="./src/jquery.tagsinput.js"></script>
<script type='text/javascript' src='https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.13/jquery-ui.min.js'></script>
<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.13/themes/start/jquery-ui.css" />


<script type="text/javascript">
    function onAddTag(tag) {
        alert("Added a tag: " + tag);
    }
    function onRemoveTag(tag) {
        alert("Removed a tag: " + tag);
    }
    function onChangeTag(input,tag) {
        alert("Changed a tag: " + tag);
    }
    $(function() {
        $('#tags_2').tagsInput({
            width: 'auto',
            onChange: function(elem, elem_tags)
            {
                var languages = ['php','ruby','javascript'];
                $('.tag', elem_tags).each(function()
                {
                    if($(this).text().search(new RegExp('\\b(' + languages.join('|') + ')\\b')) >= 0)
                        $(this).css('background-color', 'yellow');
                });
            }
        });
    });
</script>
<!-- body   -->
        <p><label>Tags</label>
        <input id="tags_2" type="text" class="tags" value="php,ios,javascript,ruby,android,kindle" /></p>

这是我的主页

<div id="insert" class="form-action show">
  <h1>Insert</h1>
  <p>

  </p>
  <form action="insert.php" method="post">
    <ul>

      <li>
        <?php include 'tag.php';?>
      </li>

      <li>
        <input type="submit" value=" Submit " name="submit" class="button" />
      </li>
    </ul>
  </form>
</div>

如果有帮助，jquery.tagsinput.css

div.tagsinput {
  border: 1px solid #CCC;
  background: #FFF;
  padding: 5px;
  width: 300px;
  height: 100px;
  overflow-y: auto
}

div.tagsinput span.tag {

  width: 100%;

}

.not_valid {

在 ma​​in.php head 标签 中加载 jquery
