POST未经检查的HTML复选框 [英] POST unchecked HTML checkboxes

问题描述

我有一大堆默认选中的复选框。我的用户可能会取消选中一些（如果有的话）复选框，并将其余的选中。

I've got a load of checkboxes that are checked by default. My users will probably uncheck a few (if any) of the checkboxes and leave the rest checked.

是否有任何方法可以使POST表单被选中不是的复选框，而不是 检查？

Is there any way to make the form POST the checkboxes that are not checked, rather than the ones that are checked?

推荐答案

为复选框添加一个不同ID的隐藏输入：

Add a hidden input for the checkbox with a different ID:

<input id='testName' type='checkbox' value='Yes' name='testName'>
<input id='testNameHidden' type='hidden' value='No' name='testName'>

在提交表单之前，根据检查的条件禁用隐藏的输入：

Before submitting the form, disable the hidden input based on the checked condition:

if(document.getElementById("testName").checked) {
    document.getElementById('testNameHidden').disabled = true;
}
