<input type="radio" name="alwaysOn" onchange="this.checked=true" checked="checked">
<input type="radio" name="alwaysOff" onchange="this.checked=false" >

<input type="checkbox" readonly="readonly" name="..." />

jquery:

$(':checkbox[readonly]').click(function(){
            return false;
        });

它仍然可能是一个好主意，给一些视觉提示(css，文本，…)，控件将不接受输入。

我会对ConroyP的回答进行评论，但这需要50个声望，而我没有。我确实有足够的声誉来发布另一个答案。对不起。

The problem with ConroyP's answer is that the checkbox is rendered unchangeable by not even including it on the page. Although Electrons_Ahoy does not stipulate as much, the best answer would be one in which the unchangeable checkbox would look similar, if not the same as, the changeable checkbox, as is the case when the "disabled" attribute is applied. A solution which addresses the two reasons Electrons_Ahoy gives for not wanting to use the "disabled" attribute would not necessarily be invalid because it utilized the "disabled" attribute.

假设有两个布尔变量$checked和$disabled:

if ($checked && $disabled)
    echo '<input type="hidden" name="my_name" value="1" />';
echo '<input type="checkbox" name="my_name" value="1" ',
    $checked ? 'checked="checked" ' : '',
    $disabled ? 'disabled="disabled" ' : '', '/>';

如果$checked为true，则复选框显示为选中。如果$checked为false，则该复选框显示为未选中。当且仅当$disabled为false时，用户可以更改复选框的状态。当复选框未选中时，不管用户是否选中，“my_name”参数都不会发布。“my_name=1”参数在复选框被选中时被发布，无论用户是否选中。我相信这就是Electrons_Ahoy一直在寻找的。

<input name="testName" type="checkbox" disabled>

很晚才开始，但我找到了MVC的答案 我禁用了复选框，并在复选框之前添加了一个HiddenFor，因此当它发布时，如果首先找到隐藏字段并使用该值。这是可行的。

 <div class="form-group">
     @Html.LabelFor(model => model.Carrier.Exists, new { @class = "control-label col-md-2" })
         <div class="col-md-10">
              @Html.HiddenFor(model => model.Carrier.Exists)
              @Html.CheckBoxFor(model => model.Carrier.Exists, new { @disabled = "disabled" })
              @Html.ValidationMessageFor(model => model.Carrier.Exists)
          </div>
 </div>

如果你不能使用'disabled'属性(因为它会擦除值的 input at POST)，并注意到html属性'readonly'只工作 在文本区域和一些输入(文本，密码，搜索，据我所见)， 最后，如果你不想重复你所有的 您可能会发现，带有隐藏输入逻辑的选择、复选框和单选 下面的函数或任何他的内部逻辑你喜欢:

    addReadOnlyToFormElements = function (idElement) {
        
            // html readonly don't work on input of type checkbox and radio, neither on select. So, a safe trick is to disable the non-selected items
            $('#' + idElement + ' input[type="checkbox"]:not(:checked)').prop('disabled',true); 
     
            // and, on the selected ones, to disable mouse/keyoard events and mimic readOnly appearance
            $('#' + idElement + ' input[type="checkbox"]:checked').prop('tabindex','-1').css('pointer-events','none').css('opacity','0.5');
        }

没有什么比删除这些只读更容易的了

removeReadOnlyFromFormElements = function (idElement) {

    // Remove the disabled attribut on non-selected
    $('#' + idElement + ' input[type="checkbox"]:not(:checked)').prop('disabled',false);

    // Restore mouse/keyboard events and remove readOnly appearance on selected ones
    $('#' + idElement + ' input[type="checkbox"]:checked').prop('tabindex','').css('pointer-events','').css('opacity','');
}
