如何从JavaScript中调用一个控制器方法 [英] How to call a controller method from Javascript

问题描述

我在一个表中显示了一堆的电影，我最终删除每部电影通过JavaScript它隐藏分区。

I am displaying a bunch of movies in a table, I am eventually deleting each movie through Javascript which hides the div.

我现在想从数据库中删除电影一样，所以什么叫从Javascript的控制器方法的最佳方法是什么？

I now want to delete the movie from the database as well, so what is the best way to call the controller method from the Javascript?

推荐答案

有一个 HTTPPost 操作方法，在你的电影控制器删除

Have an HTTPPost action method to delete in your movie controller

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

和在你看来，

<a href="#" data-movieId="34" class="movie">Delete Avengers</a>
<a href="#" data-movieId="35" class="movie">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>
