You can't. JavaScript doesn't execute when generating the action URL. What you can do, is do something like this:
你不能。生成操作 URL 时不执行 JavaScript。你可以做的是做这样的事情：
function name(myjavascriptID) {
var link = '@Url.Action("download file", "download", new { id = "-1" })';
link = link.replace("-1", myjavascriptID);
jQuery("#list_d").jqGrid('setGridParam', { url: link, page: 1 });
}

I do something fairly similar, but less verbose:
我做了一些非常相似但不那么冗长的事情：
var myUrl = '@Url.Action("Solution","Partner")/' + myjavascriptID;
$.ajax.load(myUrl); // or whatever
We can do this because of routing, and ultimately Url.Action with route dictionary parameters translates into a URI that looks like:
由于路由，我们可以这样做，最终带有路由字典参数的 Url.Action 转换为一个 URI，如下所示：
http://localhost:41215/Partner/Solution?myJavascriptID=7
Just a second choice, because as a wise old man once said "It is our choices, Harry, that show what we truly are, far more than our abilities."
只是第二个选择，因为正如一位聪明的老人曾经说过的那样，“这是我们的选择，哈利，展示了我们的真实身份，远远超过我们的能力。”

You can pass in the variables to any link as shown below...
您可以将变量传递到任何链接，如下所示...
var url = '@Html.Raw(@Url.Action("MethodName", "ControllerName"))' + '?id = ' + myjavascriptID

In the same vein as Brian Mains's answer, you could format your url string instead of replacing -1 with your variable, that is if like me, you judge it is better to read. The following answer assumes that you've modified String's prototype as suggested in this answer:
与 Brian Mains 的回答一样，您可以格式化您的 url 字符串，而不是将 -1 替换为您的变量，也就是说，如果像我一样，您认为阅读会更好。以下答案假定您已String按照本答案中的建议修改了原型：
var url = unescape('@Url.Action("download file", "download", new { id = "{0}" })').format(myjavascriptID);
The unescapecall is necessary if you want to decode your {0}. I like this alternative, because it makes it easier to have multiple parameters from JS variables. For instance:
的unescape，如果你想你的电话解码是必要的{0}。我喜欢这个替代方案，因为它可以更容易地从 JS 变量中获得多个参数。例如：
var url = unescape('@Html.Raw(Url.Action("Action", "Controller", new { id = "{0}", name = "{1}" }))').format(myID, myName);
I added Html.Rawin my second example in order to avoid having &in the url string.
我Html.Raw在我的第二个例子中添加了以避免&在 url 字符串中出现。

You can replace url like code below
您可以像下面的代码一样替换 url
var jsUrl = '@Url.Action("action", "controller")'; // ## is the token
var getUrl = jsUrl.replace('action', action).replace('controller', controller)
$("#RenderPartial").load(getUrl);

You can build the JavaScript code in C# this way:
您可以通过以下方式在 C# 中构建 JavaScript 代码：
function fun(jsId) {
var aTag = '<a href="@Html.Raw(@Url.Action("ActionName", "ControllerName", new { objectId = "xxx01xxx" }).Replace("xxx01xxx", "' + jsId + '"))">LINK</a>';
}
Here is the code from the question rewritten using this technique:
以下是使用此技术重写的问题中的代码：
function name(myjavascriptID) {
jQuery("#list_d").jqGrid('setGridParam', { url: '@Html.Raw(@URL.Action("download file", "download", new { id = "XXXmyjavascriptIDXXX" }).Replace("XXXmyjavascriptIDXXX", "' + myjavascriptID + '"))', page: 1 });
}
