Ajax 操作链接直接来自 DropDownList
我的页面一侧有一个小链接框，它呈现为 PartialView。
在其中我有一个 dropDownlist 应该更改框中链接的路由值，但我很难这样做。
我当前的计划是调用类似于 Ajax.ActionLink 的方法，根据下拉选择的值使用不同的参数将部分视图重新加载到 中。
然而，我在这方面遇到了多个问题，例如，作为使用下拉列表的新手，我不知道如何调用所选值。
<%= Html.DropDownList("DropDownList1", new SelectList(Model, "ID", "Name"), "--Pick--", new { AutoPostBack = "true", onchange = "maybe something here" })%>
我尝试将 sys.mvc.AsyncHyperlink 放入 onchange 属性中，并且该方法有效，但我不知道如何为其放入路由值。
Sys.Mvc.AsyncHyperlink.handleClick(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, updateTargetId: 'SmallMenu' }
是否没有直接的 Ajax 下拉列表可以触发 onchange 事件？
有什么办法这可能吗？
我稍后在部分视图中看到了 Ajax 操作链接，但它们需要通过下拉列表中的值更新它们的 id，如果我能以其他方式做到这一点，我将不胜感激。
I've got a small linkbox on the side of my page that is rendered as a PartialView.
In it I have a dropDownlist the should change the routing value of the links in the box but I'm having difficulty doing so.
My current plan is to call on something similar to a Ajax.ActionLink to reload the partial view into the with a different parameter based on the value of the dropdown selection.
However I'm having multiple problems with this, for example as a novice in using dropdownlists I have no idea how to call on the selected value for example.
<%= Html.DropDownList("DropDownList1", new SelectList(Model, "ID", "Name"), "--Pick--", new { AutoPostBack = "true", onchange = "maybe something here" })%>
I tried putting in the sys.mvc.AsyncHyperlink into the onchange attribute and that worked except I don't know how to put in the route value for it.
Sys.Mvc.AsyncHyperlink.handleClick(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, updateTargetId: 'SmallMenu' }
Is there no straight Ajax drop down list that fires events onchange?
Any way this is possible?
I have later in the Partial view the Ajax actionlinks but they need to have their id's updated by the value in the dropdownlist and if I could do that somehow else I would appreciate a suggestion.

好吧，有点忘记了这一点。
我找到了一个解决方案，可以解决一些问题，并且可能解决所有问题。
作为 MVC 和 Ajax 的新手，我后来发现我可以将 DropDownList 放入 Ajax.BeginForm 中，以发布下拉列表的结果。我没有把它自动回发可能是因为我没有花太多时间在上面。
OK had kinda forgot about this.
I found a solution that solved some of the problems and can possibly solve all of them.
As a newbie in MVC and Ajax I later figured that I could put the DropDownList into a Ajax.BeginForm that would post the result of the dropdownlist. I didn't get it to autopostback probably cuause i didn't spend to much time on it.
