Atlas中新增了ErrorTemplate,在实用性上进了一大步.
也想着体验体验,但自己琢磨了半天不行, 再按在网上的一些范例试试,也不行.网上范例模板大多如下:
ErrorTemplate
<atlas:ScriptManager runat="server" 
>
<ErrorTemplate>
There was an error processing your action.<br />
<span id="errorMessageLabel"></span>
<hr />
<button type="button" id="okButton">OK</button>
</ErrorTemplate>
</atlas:ScriptManager>
原本希望在
errorMessageLabel中显示错误提示信息,然后通过
okButton返回继续,可是根本不能实现.
今天早上反复试验,最后发现
errorMessageLabel,okButton的runat必须是runat="server"才能成功.
<span id="errorMessageLabel" runat="server"/>
<button type="button" id="okButton" runat="server">OK</button>
另外,
Atlas的Sys.WebForms.PageRequestManager对象中有两个有用的方法,可用在Client端.
get_pageErrorMessage() 是用于获取服务端返回的错误信息.
clearError() 清除错误信息和标志,使页面重新可用.
(被它搞死了,特此纪念.)
