如何从控制器返回JavaScript? [英] How to return JavaScript from controller?

问题描述

我正在使用ASP.NET Core 2.2项目，需要从控制器返回JavaScript.但是，我怀疑没有直接的方法，因此，我遵循了此 OS的回答，并更改了我的代码，如下所示:

I'm working with the ASP.NET Core 2.2 project where I need to return JavaScript from the controller. However, I suspect that there is no direct way, hence, I followed this OS answer and changed my code as following:

public IActionResult MyAction()
{
    var sb = new StringBuilder();
    sb.Append("$(document).ready(function(){");
    sb.Append("alert('hi')");
    sb.Append("});");            
    return new JavaScriptResult(sb.ToString());
}

---

public class JavaScriptResult : ContentResult
{
    public JavaScriptResult(string script)
    {
        this.Content = script;
        this.ContentType = "application/javascript";
    }
}

尽管它只是在编写纯文本.有没有办法?

Though it's just writing plain text instead. Is there way around?

推荐答案

您可以使用ajax在页面中加载javascript:

You can use ajax to load the javascript , in your page :

<script>
    $(function () {
            $.getScript("/Controller/Action");
    });

</script>

您的发球边:

public IActionResult DoSomething()
{
    return new  JavaScriptResult("alert('Hello world!');");
}

public class JavaScriptResult : ContentResult
{
    public JavaScriptResult(string script)
    {
        this.Content = script;
        this.ContentType = "application/javascript";
    }
}
