在JS中捕获一个“On_click()”事件并像这里一样检查它怎么样?：

I have a lengthy form (250+ fields) that posts to a db. It is an online employment application. When an admin goes to look at an application that has been filed, the form is populated with data from the db. Input texts and textareas are replaced with the text they submitted but the radios and checkboxes are useful to keep as form elements. Disabling them makes them harder to read. Setting the .checked property to false onclick won't work because they may have been checked by the user filling out the app. Anyhow...

onclick="return false;"

工作就像一个“禁用”无线电和复选框事实上的魅力。

对于未选中的单选按钮，将它们标记为禁用。这将阻止它们响应用户输入并清除选中的单选按钮。例如:

<input type="radio" name="var" checked="yes" value="Yes"></input>
<input type="radio" name="var" disabled="yes" value="No"></input>

最好的解决方案是设置已检查或未检查状态(无论是从客户端还是服务器)，并且不让用户更改它之后(即使其为只读)执行以下操作:

<input type="radio" name="name" onclick="javascript: return false;" />

我通过只禁用未选中的单选按钮来伪造单选按钮的只读。它可以防止用户选择不同的值，并且选中的值将始终在提交时发布。

使用jQuery使只读:

$(':radio:not(:checked)').attr('disabled', true);

这种方法也适用于将选择列表设置为只读，只是需要禁用每个未选择的选项。
