javascript - jQuery UI 错误 - 未捕获的语法错误 : Unexpected Identifier

我正在尝试实现一个 jQuery slider ，它绑定(bind)到一个选择框，作为我正在整理的调查问卷的一部分。但是，我在 Chrome 中收到 Uncaught SyntaxError 错误，在 IE 中收到 预期 ')' 错误。

我使用的 jQuery 如下，是从 jQuery UI 站点找到的直接副本 here :

<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />
<script src="http://code.jquery.com/jquery-1.9.1.js" type="text/javascript"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js" type="text/javascript"></script>
<script type="text/javascript">
  $(function() {
    var select = $( ".minbeds" );
    var slider = $( "<div id="slider"></div>" ).insertAfter( select ).slider({
      min: 1,
      max: 4,
      range: "min",
      value: select[ 0 ].selectedIndex + 1,
      slide: function( event, ui ) {
        select[ 0 ].selectedIndex = ui.value - 1;
      }
    });

    $( ".minbeds" ).change(function() {
      slider.slider( "value", this.selectedIndex + 1 );
    });
  });
</script>

我对代码所做的唯一更改是，我将 #minbeds 和 ID 更改为类 (.minbeds)。

HTML 如下:

    <select class="minbeds">
      <option>1</option>
      <option>2</option>
      <option>3</option>
      <option>4</option>
    </select>

现在，代码似乎工作正常，在我的本地计算机上没有错误，但是当我将其放入 CMS 中时，我在以下内容之间收到 Uncaught SyntaxError: Unexpected Identifier 错误行( Chrome ):

var slider = $( "<div id="slider"></div>" ).insertAfter( select ).slider({

和

min: 1,

在 IE9 中，我得到预期')'，其中星号表示此处:

var slider = $( "<div id="*slider"></div>" ).insertAfter( select ).slider({

有人知道为什么会发生这种情况吗？关于如何缩小错误范围有什么想法吗？我尝试过使用 JSLint，但我不知道如何正确使用它。

这里是 CMS 的完整源代码(如果有帮助的话):

最佳答案

尝试一下

var slider = $( "<div id='*slider'></div>" ).insertAfter( select ).slider({

或者直接你可以这样做

var slider = $( "div #slider" ).insertAfter( select ).slider({

我认为您需要将 select 放在单引号或双引号中。
