推荐答案

如何在前端javascript功能中使用后端变量.您可以尝试使用隐藏字段.您可以将值设为隐藏字段，并将隐藏字段的ID传递给脚本函数.

这是更多有关隐藏字段的信息.

删除

Remove the

runat="server"

它会起作用.

但是，如果要使其成为服务器端控件，则必须在页面OnLoad part中设置其OnClick :

and it will work.

but if you want it to be server side control you have to set its OnClick in page OnLoad part :

HyperLink2.Attributes.Add("OnClick", string.Format("showHelp('{0}','{1}');", hostCompanyID, portaltype1));

希望对您有所帮助.

Hope it helps.
