（ .statuscheck）。attr（' 已禁用'， 已禁用）;
document .getElementsByClassName（ statuscheck).disabled = false ;
}）;

 <  表    class   =  table table-bordered >  
 <   tr     class   =  statuscheck >  
 <   td  >  
 <   asp：RadioButtonList     ID   =  rbtnRegis ter    runat   =  server    CssClass   = 注册    RepeatDirection   = 水平 > ;

 <   asp：ListItem    值  =  4   文本  = 注册根据Tenent >  <   / asp：ListItem  >  
 <   / asp：RadioButtonList  >  
 <   / td  >  
 <   td  >  
 <   div     class   =  input-group    style   =  float：left; >  
 <   asp： TextBox     ID   =  txtStatus2Date    runat   =  server    CssClass   =  form-control >  <   / asp：TextBox  >  
 <   / div  >  
 <   / td  >  
 <   td     style   =  text-align：center; >  
 < ;   asp：按钮    ID   =  btnStatus2    runat   =  server    CssClass   =  btn btn-primary   文本  = 保存    OnClick   =  btnStatus2_Click >  <   / asp：按钮 >  
 <   / td  >  
 <   / tr  < span class =code-keyword>>  
 <   / table  >  

表行上不存在禁用属性。您必须在其内部输入元素上应用它。此外， jQuery文档 [ ^ ]建议使用 .prop（）而不是 .attr（）用于DOM属性，例如禁用。



因此，禁用/启用所有输入元素一行，试试这个：

  //  禁用 

Hi,

Any one can help me how to disabled HTML using JavaScript,jQuery below is my code.

<script type="text/javascript">
			$(document).ready(function () {
			$(".statuscheck").attr('disabled', "disabled");
            document.getElementsByClassName("statuscheck").disabled = false;
		});

<table class="table table-bordered">
	<tr class="statuscheck">
		<td>
			<asp:RadioButtonList ID="rbtnRegister" runat="server" CssClass="register" RepeatDirection="Horizontal">
				<asp:ListItem Value="3" Text="Register By Company"></asp:ListItem>
				<asp:ListItem Value="4" Text="Register By Tenent"></asp:ListItem>
			</asp:RadioButtonList>
		</td>
		<td>

			<asp:Button ID="btnStatus2" runat="server" CssClass="btn btn-primary" Text="Save" OnClick="btnStatus2_Click"></asp:Button>
		</td>
	</tr>
 </table>

解决方案

(document).ready(function () {

(".statuscheck").attr('disabled', "disabled"); document.getElementsByClassName("statuscheck").disabled = false; });

<table class="table table-bordered">
	<tr class="statuscheck">
		<td>
			<asp:RadioButtonList ID="rbtnRegister" runat="server" CssClass="register" RepeatDirection="Horizontal">
				<asp:ListItem Value="3" Text="Register By Company"></asp:ListItem>
				<asp:ListItem Value="4" Text="Register By Tenent"></asp:ListItem>
			</asp:RadioButtonList>
		</td>
		<td>
			<div class="input-group" style="float: left;">
				<asp:TextBox ID="txtStatus2Date" runat="server" CssClass="form-control"></asp:TextBox>
			</div>
		</td>
		<td style="text-align: center;">
			<asp:Button ID="btnStatus2" runat="server" CssClass="btn btn-primary" Text="Save" OnClick="btnStatus2_Click"></asp:Button>
		</td>
	</tr>
 </table>

The disabled attribute does not exist on a table row. You have to apply it on its inner input elements. Also, the jQuery documentation[^] recommends to use .prop() instead of .attr() for DOM properties such as disabled.

So, to disable/enable all input elements in a row, try this:

// to disable
