我正在尝试编写一个脚本，根据用户在上一页输入的内容禁用按钮。但是，当我直接将 disabled="disabled" 放入输入行时，我什至无法禁用按钮。当我在 .html 页面上输入下面完全相同的代码时，它工作正常并且按钮被禁用。我对网络开发很陌生，我不明白这里发生了什么。我指定<!DOCTYPE html>并且按钮在<html>标签内。知道为什么这个简单的命令不起作用吗？

<input type="button" id="b1" value ="How much can weight loss reduce my risk?" style="white-space:normal" disabled="disabled"/>

如果你的按钮是HtmlButton你可以试试

myBtn.Attributes.Add("disabled","disabled");

它对我有用。

尝试使用 <asp:Button id="b1" Text="Submit" disabled="disabled" runat="server" />
