如何设置在selectize.js中选择项目时显示的文字？

Question

我在我的网页上使用 selectize.js 作为多个 select。 HTML 片段：

<select class="form-control" id="select_dd" multiple="multiple">
   <option value="TEXT_TO_DISPLAY">
      DECRIPTION
   </option>
</select>

但是当我选择项目时，selections输入框中显示的文本是DESCRIPTION。我如何显示 "value" 属性而不是 "text" 属性。

非常感谢

一种方法是使用 render 选项：这样做的好处是您可以随意选择选项文本和所选文本：

$('#select_dd').selectize({
      render: {
        option: function(item, escape) {
         return '<div>' + item.text + ' </div>';
        },
        item: function(item, escape) {
          return '<div>' + item.value + ' whatever </div>';
        }
      }
    });
