如何用客户端脚本触发服务器端控件的事件

问题：<asp:ImageButton id="WritConfirm" runat="server" ImageUrl="../images/icon_yes.gif"></asp:ImageButton>。这是服务器端控件。如何在客户端脚本 function doSelect(){ }中触发上个控件的click事件？

思归的答复是：you might need to change 'WritConfirm" to its client ID
function doSelect(){ document.getElementById('WritConfirm').click(); }

还有一个办法是：__doPostBack('WritConfirm','');

但是思归是不提倡用的：you shouldn't call __doPostBack directly since the function is generated by the ASP.NET engine, it could be changed in the next release.   if you want to, you should be calling Page.GetPostBackEventReference
