asp.net - imagebutton onclientclick 和 onclick 事件

Question

如何将 onclentclick 和 onclick 事件从代码隐藏添加到图像按钮。我编写了一些代码，它显示 onclientclick 事件的确认消息，但不触发 onclick 事件。

我的代码如下..

ImageButton img = new ImageButton();
img.ID = "img1";
img.Visible = true;
img.OnClientClick = "alert(confirm('Are you sure you want to delete folder with files ?'));";
img.Click += new ImageClickEventHandler(img_Click);
img.ImageUrl = "~/images/admin/remove.png";

事件代码是:

void img_Click(object sender, ImageClickEventArgs e)
{
 //code what i want to implement   
}

Answer 1

更改OnClientClick如下

   img.OnClientClick = "return confirm('Are you sure you want to delete folder with files ?');";

或者您可以在 aspx 页面中添加脚本作为方法，然后从 OnClientClick 调用该脚本

img.OnClientClick ="ConfirmDelete()";


<script type="text/javascript">
function ConfirmDelete()
  {
      return confirm('Are you sure you want to delete folder with files ?');
  }
</script>
