POST 未选中的 HTML 复选框 [英] POST unchecked HTML checkboxes

问题描述

我有很多默认选中的复选框.我的用户可能会取消选中一些(如果有)复选框，而将其余复选框保持选中状态.

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.

有什么办法可以让表单发布未选中的复选框，而不是选中的复选框?

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

为具有不同 ID 的复选框添加隐藏输入:

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'>

提交表单前，根据勾选的条件禁用隐藏输入:

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

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