推荐答案

Button btn = new Button();
btn.Text = "Delete";
btn.Attributes["onclick"] = "javascript: if( confirm(''Do you want to delete?'') ) { delete(); } return false;";

Controls.Add(btn);

与Mark相似，但是我通常这样做会触发删除"服务器的功能.

因此，通过修改他的JavaScript即可:

similar to Mark''s, but what I usually do it fire the "delete" functionality from the server.

Therefore, by modifying his JavaScript a smidge:

btn.Attributes["onclick"] = "javascript: return confirm(''Do you want to delete?'');";

通过将确认(其结果为真/假值)直接传递给onclick处理程序，如果返回cancel/false属性，则onclick不会完成，并且表单提交不会发生.

By passing the confirm (which gives a true/false value as a result) directly to the onclick handler, if you return a cancel/false attribute, the onclick doesn''t complete and the form submittal will not occur.
