推荐答案

您是否有机会在应用程序中使用母版页(ASP.NET)?如果是，请检查这些

ID，ClientID和UniqueID之间的区别 [控制ASP.NET中的Web控件ClientID值 [

Are you using Master pages(ASP.NET) in your application by any chance? If yes then check these

The difference between ID, ClientID and UniqueID[^]
Take Control Of Web Control ClientID Values in ASP.NET[^]

For example, use things like below

document.getElementById('<%=txtapproval.ClientID%>').value;

代替

instead of

document.getElementById("cphContents_txtapproval").value;
