Question

如何将一个或多个事件添加到以这种方式添加的下拉列表中

@ Html.DropDownList（“List”）？

Answer 1

如果你习惯使用jQuery：，试试这个：

     $("#DropDownListID").change(function () {
        var selectedValue = $(this).val();
        //Do whatever you want to do on selection changes here
     });

Answer 2

@Html.DropDownList("PageItemDD", (SelectList)ViewBag.itemsPerPage, new { onchange = "document.location.href = '/List?ipp=' + this.options[this.selectedIndex].value;" })

new { onchange = "document.location.href = '/List?ipp=' + this.options[this.selectedIndex].value;" }部分（DropDownList的第3个参数）是html属性。在这种情况下，我有一个onchange来覆盖此页面：/List?ipp= the value of the dropdownlist
