ASP.NET MVC Javascript ActionResult
提问by Joseph
Anyone have any examples of javascript actionresults? I am having a hard time getting the script to execute once it has been returned. Thanks
任何人都有javascript actionresults的例子？一旦脚本返回，我很难让脚本执行。谢谢

Here's an example I found on a blog post, which actually describes it as an anti-pattern, because the Controller has to have in-depth knowledge of the View in order to function.
这是我在博客文章中找到的一个示例，它实际上将其描述为反模式，因为控制器必须对视图有深入的了解才能发挥作用。
public ActionResult DoSomething() {
string s = "$('#some-div').html('Updated!');";
return JavaScript(s);
}

The only way I have found to return a JavascriptResult and execute it on the client is with JQuery:
我发现返回 JavascriptResult 并在客户端执行它的唯一方法是使用 JQuery：
<script>
$(document).ready(function () {
$("button").click(function () {
$.getScript("/Home/ShowAlert");
});
});
</script>
<button>Use Ajax to get and then run a JavaScript</button>
In the controller:
在控制器中：
public JavaScriptResult ShowAlert() {
var script = "alert('Hello');";
return new JavaScriptResult() { Script = script };
}

This might work..
这可能有效..
public ActionResult Search(string name)
{
// var someScript = Server.HtmlEncode("<script>alert('Hello')</script>");
return Content("<script>alert('Hello')</script>" );
}
