检查每个组中至少选择了一个单选按钮(使用jQuery) [英] checking at least one radio button is selected from each group (with jquery)

问题描述

我正在表单上动态拉出并显示单选按钮问题(通过jquery选项卡分为不同的部分).

I'm dynamically pulling and displaying radio button quesitons on a form (separated into different sections by jquery tabs).

因此，共有2个，3个，4个，5个等单选按钮，它们具有相同的名称"但ID不同.

So there are lots of 2, 3, 4, 5 etc radio buttons together, which have the same 'name' but different ids.

当您在各部分之间单击时，我要检查是否为每个组至少选择了一个单选按钮.

When you hit next between the sections, I want to check that at least one radio button has been selected for each group.

(加载表单时，默认情况下不选中单选按钮，而必须采用这种方式.)

( When the form loads, the radio buttons have none checked by default and it has to be this way. )

我可以循环浏览当前部分的单选按钮，但是我不确定如何轻松地检查每个组是否已被选中?

I can loop through the current section's radio buttons but I'm not sure how to easily check that one has been checked for each group?

推荐答案

在元素之间没有任何关系或如何查找组名的情况下，我只能给您一个指针，但这应该可以工作(触发了检查通过单击id="nextButton"的元素，但是显然可以将其自定义为任何其他适当的事件，例如$('form').submit()):

In the absence of any relationship between elements, or how to find the group names, I can only give you a pointer, but this should work (the check's triggered by clicking on the element of id="nextButton", but obviously this can be customised to any other appropriate event, such as $('form').submit(), for example):

$(document).ready(
function(){
  $('#nextButton').click(
    function(){

    var radioName = something; // use this if there's a relationship between the element
                               // triggering this check and the radio buttons

      if ($('input[name='+ radioName +']:checked').length) {
           // at least one of the radio buttons was checked
           return true; // allow whatever action would normally happen to continue
      }
      else {
           // no radio button was checked
           return false; // stop whatever action would normally happen
      }
    }
  );
}
);
