如何重置/取消选中单选按钮onclick事件? [英] How to reset/uncheck radio button onclick event?

问题描述

我有2个单选按钮，分为2组.

I have 2 radio button with 2 group.

结构是这样的

1. 主广播1
2. 主电台2

在主电台2下，还有两个子单选按钮.

Under Main Radio 2, there's two more sub radio button.

1. 主广播1
2. 主电台2
   • 副电台1
   • 第二广播电台

1. Main Radio 1
2. Main Radio 2
   • Sub Radio 1
   • Sub Radio 2

我在做什么，在默认阶段，它将仅显示Main Radio 1和Main Radio 2按钮.当选择主要电台2，主营广播的两个子单选按钮2出现.

What am I doing is, in default stage, it will only show Main Radio 1 and Main Radio 2 button. When choose Main Radio 2, two sub radio button of Main Radio 2 appear.

选择返回主广播1时，它将隐藏主广播2的列表.

When choose back to Main Radio 1, it will hide the list of Main Radio 2.

我想要实现的是，

当单击Main Radio 1时，我对Sub Radio 1或Sub Radio 2所做的选择也要取消选中/重置.

When click Main Radio 1, the selection that I made for Sub Radio 1 or Sub Radio 2, want to be uncheck / reset too.

我尝试使用此javascript，但未成功.

I tried with this javascript, but no success.

document.getElementById("subradiobuttons").reset(); 

请帮助我解决方案.谢谢.

Please kindly help me the solutions. Thank you.

谨此问候

推荐答案

我认为，完成此类简单任务的最佳方法不需要像jQuery这样的完整JavaScript库.

I think the best approach for a simple task like this does not needs a full JavaScript library like jQuery.

document.getElementById("main2").addEventListener("click", function()
{
    document.getElementById("subCheckButtons").style.opacity = 1;
}, false);
document.getElementById("main1").addEventListener("click", function()
{
    document.getElementById("subCheckButtons").style.opacity = 0;
    document.getElementById("sub1").checked = false;
    document.getElementById("sub2").checked = false;
}, false);

<input type="radio" id="main1" name="main" />
<input type="radio" id="main2" name="main" />
<div id="subCheckButtons" style="opacity:0;">
    <input type="radio" id="sub1" name="sub" class="subCheck" />
    <input type="radio" id="sub2" name="sub" class="subCheck" />
</div>
