使用多组单选按钮进行JQuery验证

I have a form that did submit 1 out of 8 radio buttons to a php $_POST super global array. Therefore, I needed some validation. I was kindly helped by being provided this code which works great:

$("#form").submit(function (event) {

            if(!$(":radio:checked").length) {

            alert("You must select at least one emotional state!");
            event.preventDefault();

            }
        });

However, I have now been asked to have 2 sets of 8 radio buttons in which the user selects 2 answers instead of the initial 1 answer. I need the code to be able to determine that at least one radio button from each set of 8 buttons has been selected before the form is submitted. At the moment the code checks to see if any radio buttons have been selected, then as soon as just 1 buttons is selected, the function is satisfied and transitions to the next page, which is not what I want.

EDIT

Buttons code:

<p><input type="radio" value="happy" name="perceived_emotion">Happy
<input type="radio" value="excited" name="perceived_emotion">Excited
<input type="radio" value="angry" name="perceived_emotion">Angry
<input type="radio" value="frustrated" name="perceived_emotion">Frustrated
<input type="radio" value="miserable" name="perceived_emotion">Miserable
<input type="radio" value="sad" name="perceived_emotion">Sad
<input type="radio" value="tired" name="perceived_emotion">Tired
<input type="radio" value="relaxed" name="perceived_emotion">Relaxed</p>

<p><input type="radio" value="happy" name="induced_emotion">Happy
<input type="radio" value="excited" name="induced_emotion">Excited
<input type="radio" value="angry" name="induced_emotion">Angry
<input type="radio" value="frustrated" name="induced_emotion">Frustrated
<input type="radio" value="miserable" name="induced_emotion">Miserable
<input type="radio" value="sad" name="induced_emotion">Sad
<input type="radio" value="tired" name="induced_emotion">Tired
<input type="radio" value="relaxed" name="induced_emotion">Relaxed</p>

Here is the form code:

<form id="form" action="audio_handler.php?id=1" method="POST">

                <div id="perceived_emotions">
                <?php include("includes/induced_emotion_buttons.php"); ?>       
                </div>

                <br />

                <div id="induced_emotions">
                <?php include("includes/perceived_emotion_buttons.php"); ?>
                </div>

                <p class="right"><input type="submit" name="submit" value="Submit"></p>

            </form>

    What you want to do is use the [name="value"] selector in JQuery in conjunction with the :checked selector. So your new code would be:

    if(!$('input[name="perceived_emotion"]:checked').length) {
      alert("You must select at least one perceived emotional state!");
      event.preventDefault();
      return false;
    }
    
    if(!$('input[name="induced_emotion"]:checked').length) {
      alert("You must select at least one induced emotional state!");
      event.preventDefault();
      return false;
    }
    

    All of that wrapped into the form event.

    EDIT: Since you only want to display one dialog at once, just add return false; in each if statement.
