<asp:TextBox ID="txtRevisionFee" runat="server" ></asp:TextBox>
<asp:Button ID="Button1" runat="server" OnClientClick="Check()" Text="测试" />代码是在文本框里输入“是”的时候，后面一个文本框就不可用。可是怎么都实现不了。问题是。当我把最后一段代码document.getElementById('txtRevisionFee').disabled=true;中的'txtRevisionFee'改成'Button1'就可以实现按钮不可用了。
document.getElementById('txtRevisionFee').readOnly="readOnly";

The following elements support the disabled attribute: BUTTON, INPUT, OPTGROUP, OPTION, SELECT, and TEXTAREA.
function Check()

var a=document.getElementById('a' );
if(a.value=="是"){
document.f.b.disabled=true;
alert(document.getElementById('b').getAttribute('disabled'));
