我正在处理一个onchange事件与选定的值，通过简单的HTML如下：
<select onchange="location = this.value;">
<option value="/product/categoryByPage?PageSize=15" selected="selected">15</option>
<option value="/product/categoryByPage?PageSize=30" selected="selected">30</option>
<option value="/product/categoryByPage?PageSize=50" selected="selected">50</option>
</select>
做这样：
List<SelectListItem> items = new List<SelectListItem>();
string[] itemArray = {"15","30","50"};
for (int i = 0; i < itemArray.Count(); i++)
{
items.Add(new SelectListItem
{
Text = itemArray[i],Value = "/product/categoryByPage?pageSize=" + itemArray[i]
});
}
ViewBag.CategoryID = items;
@Html.DropDownList("CategoryID")
如何使用@ Html.DropDownList()处理onchange
