function mine()
    {
        var i = 3;
        Androidobject.call();
    }

其中Androidobject是java的javascript接口.它有方法调用

WebView myWebView;

    public void call()
    {
        runOnUiThread(new Runnable()
        {
            @Override
            public void run()
            {
                myWebView.loadUrl(''javascript:alert(i);'');
            }
        });
    }

在javascript中执行“i is not defined”时,以下代码将产生错误,因为javascript将不会在调用java代码的上下文中执行.

是否可以在相同的上下文中从java方法执行JS,即在上面的情况下使“i”可见？

在这个例子中,“i”是整数,但它可能是任何类型的对象.

谢谢.

function mine()

 {

var i = 3;

Androidobject.call(i);

}

和

WebView myWebView;

public void call(Integer i)
{
Integer temp = i;
    runOnUiThread(new Runnable()
    {
        @Override
        public void run()
        {
            myWebView.loadUrl(''javascript:alert('' + temp + '');'');
        }
    });
}

谢谢,

This topic explains how to use to call
a Web service from ECMAScript
(JavaScript). To enable your
application to call ASP.NET AJAX Web
services by using client script,the
server asynchronous communication
layer automatically generates
JavaScript proxy classes. A proxy
class is generated for each Web
service for which an
<asp:ServiceReference> element is
included under the
<asp:ScriptManager> control in the page.

我现在想要从数据库中删除电影,那么从Javascript调用控制器方法的最佳方法是什么？

[HttpPost]
public ActionResult Delete(int id)
{
  try
  {
    repo.DeleteMovie(id);
    return "deleted"
  }
  catch(Exception ex)
  {
    //Log errror
  }
  return "Failed";
}

在你的视图中,

<a href="#" data-movieId="34">Delete Avengers</a>
<a href="#" data-movieId="35">Delete Iron Man</a>
<script type="text/javascript">
$(function(){

   $(".movie").click(function(e){
     e.preventDefault();
     $.post("@Url.Action("Delete","Movie")",{ id : $(this).data("movieId")},function(data){
        alert(data);
     });
   });
});

</script>
