jQuery，检查是否选中了所有单选按钮组

问题描述

我有几个radiobuttongroup，我需要在检查它们时运行一个脚本。

I have several radiobuttongroups, and I need to run a script when they are checked.

我使用以下脚本来检查是否有一个脚本被检查，如果不，然后给它上色。

I use the following script to check if one of them is checked, if not, then color it.

如何制作代码，以便在检查完所有radiobuttongroup后，运行脚本。

How can I make the code, so that when all of the radiobuttongroups are checked, then run script.

检查radiobuttongroups是否被检查的代码：

The code that checks if the radiobuttongroups are checked:

$('.aQuestion').each(function(){
  if($(this).find('input[type="radio"]:checked').length > 0)
    {
       alert("checked");
    }
  else
    {
       alert("not checked");
    }
});

radiobuttongroups（大约有90个）：

The radiobuttongroups (there is about 90 of them):

<div class='aQuestion' id='div1'>
    <STRONG>1. </STRONG>
    <STRONG>Question</STRONG></br>
    <INPUT TYPE='radio' NAME='grp1' VALUE='0'>answer 1</br>
    <INPUT TYPE='radio' NAME='grp1' VALUE='1'>answer 2</br>
    <INPUT TYPE='radio' NAME='grp1' VALUE='2'>answer 3</br>
    <INPUT TYPE='radio' NAME='grp1' VALUE='3'>answer 4</br>
    <INPUT TYPE='radio' NAME='grp1' VALUE='4'>answer 5
</div>

<div class='aQuestion' id='div2'>
    <STRONG>2. </STRONG>
    <STRONG>Question</STRONG></br>
    <INPUT TYPE='radio' NAME='grp2' VALUE='0'>answer 1</br>
    <INPUT TYPE='radio' NAME='grp2' VALUE='1'>answer 2</br>
    <INPUT TYPE='radio' NAME='grp2' VALUE='2'>answer 3</br>
    <INPUT TYPE='radio' NAME='grp2' VALUE='3'>answer 4</br>
    <INPUT TYPE='radio' NAME='grp2' VALUE='4'>answer 5
</div>

推荐答案

假设每个问题只有一个单选按钮组，您不需要重复问题以找出它们全部被选中：

Assuming there is only one radio button group per question, you don't need to iterate the questions in order to find out they're all selected:

var $questions = $(".aQuestion");
if($questions.find("input:radio:checked").length === $questions.length) {
    // All Checked
}

演示了上述内容。
