单选按钮验证(动态名称) [英] Radio button validation (dynamic name)

问题描述

我有一个单选按钮列表.每个单选按钮都有一个动态名称.有没有办法检查它们是否都被选中?因为大多数无线电验证脚本都使用静态名称.

I have a list of radio buttons. Each radio button has a dynamic name. Is there a way to check if they are all selected? Because most radio validation scripts uses a static name.

推荐答案

如果您知道某个容器的 id，您可以找到带有getElementsByTagName"的单选按钮.因此，如果您的 HTML 如下所示:

If you know the id of some container, you can find the radio buttons with "getElementsByTagName". Thus if your HTML looks something like this:

<form id='x-form' action='...'>
    <input type='radio' name='$[xyz}'>
    <!-- ... -->

然后你可以像这样检查单选按钮:

then you could check the radio buttons like this:

function allRadioButtonsSelected(formId) {
  var form = document.getElementById(formid);
  var inputs = form.getElementsByTagName('INPUT');
  for (var i = 0; i < inputs.length; ++i) {
    if (inputs[i].type.toLowerCase == 'radio' && !inputs[i].checked)
      return false;
  }
  return true;
}

如果您使用像 jQuery 这样的框架，您的生活会轻松很多.

Your life would be considerably easier if you were using a framework like jQuery.
