我正在尝试在HTML select选项中嵌入Ajax.ActionLink,如下所示

<script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"</script>

<select>
    <option>@Ajax.ActionLink("Opiton 1", "MyAction", new { parameter = "parm1" }, 
        new AjaxOptions { HttpMethod = "GET", InsertionMode = InsertionMode.Replace,             
        LoadingElementId = "myDiv" })</option>
    <option>@Ajax.ActionLink("Opiton 2", "MyAction", new { parameter = "parm1" }, 
        new AjaxOptions { HttpMethod = "GET", InsertionMode = InsertionMode.Replace,             
        LoadingElementId = "myDiv" })</option>
</select>

<div id="myDiv"></div>

行动方法

public ActionResult MyAction(string parameter)
{
    ViewModel myViewModel = new ViewModel();

    myViewModel.Parm = parameter;

    if (Request.IsAjaxRequest())
    {
        return PartialView("_MyPartial", myViewModel);
    }
    else
    {
        return View(myViewModel);
    }
}

当我将Ajax.ActionLink放在选择列表之外时,它可以正常工作并直接进入MyAction。当我在选择列表中的选项中嵌入链接时,onlclick事件无法触发。

如何在<option></option>内部触发onclick事件?

为什么select元素中有2个Action链接。我想你想调用一个action方法并将返回值设置为div。我不会使用Microsoft ajax库。我会用这样的干净的代码手工完成。(我只需要在页面中引用jQuery库。没有别的)

//include only jQuery library. Nothing else ! 

<select id="dropDown1">
   <option value="0"> Select</option>
   <option value="1"> Detroit</option>
   <option value="2"> Florida</option>
</select>

<script type="text/javascript">
 $(function(){
    $("#dropDown1").change(function(){   
       $.get("@Url.Action("MyAction", "MyController")",
                                 { "parameter" : $(this).val()},function(data){
            $("#myDiv").html(data);
        });
    });
 });
</script>
