javascript - Select2 -- 占位符不显示

Question

我在我的 asp.net mvc 5 应用程序中使用 Select2 插件。根据documentation

The placeholder option allows you to pass in a data object instead of just a string if you need more flexibility. The id of the data object should match the value of the placeholder option.

我已经完全做到了，但是占位符仍然没有出现。

代码:

model.Step6.Titles.Insert(0, new SelectListItem() { Text = "Select a Title", Value = "0", Selected = true });

@Html.DropDownListFor(model => model.Step6.Title, Model.Step6.Titles, new { id="teamtitle", @style = "width: 100%;"})

$("select").select2({
    allowClear: true,
    placeholder: {
        id: "0",
        placeholder: "Select an Title"
    }
})

谁能告诉我我做错了什么？

我认为占位符是一个字符串。不是对象 https://select2.github.io/examples.html#placeholders

$("select").select2({
    allowClear: true,
    placeholder:"Select an Title"

})
