的JavaScript ASp.net ..在存量價值在HiddenField從JavaScript錯誤。檢查代碼如下

Question

我嘗試1：

var a=confirm('Do You Really want to Save this Record?') ; 
document.getElementById('Hidden.ClientID') = a; 

我嘗試2：

var a=confirm('Do You Really want to Save this Record?') ; 
document.getElementById('Hidden.ClientID').value = a; 

代碼背後：

Response.Write(Hidden.Value); 
Response.End(); 

////////// 爲什麼Value沒有存儲在隱藏字段中？

Answer 1

嘗試，

var ele=document.getElementById('<%=Hidden.ClientID%>'); 
ele.value=a; 

Answer 2

工作守則看到

document.getElementById('<%=Hidden.ClientID%>').value="a"; 

    Code Behind :   
    Response.Write(Hidden.Value); 
    Response.End();
