根据答案检查特定的复选框

Question

I have already done a lot of research on Stack Overflow to attempt to answer this question, but most answers are to specific to answer this.

I am attempting to lock questions after the answers are selected and tell the user if the question is right or wrong.

My solution for a Multiple Checkbox style question was to have a 'confirm' button after they select there answers. In this case, I have built a generic function for me to pass the answers to and have them mapped for me. However, I am struggling to come up with a solution for Multiple Checkboxes.

The solution must revolve around javascript/jquery as I do not have control over the HTML generated from this Form Builder that I use.

TL;DR

My solution below fails to correctly recognize wrong answers for Question 14, it should only pop up 'Correct!' if option 3 AND 4 are both selected.

Currently, it pops up correct if they select 3 and any other option.

For a version to work with: Fiddle

HTML:

<div id="q14" class="q required highlight">
<a class="item_anchor" name="ItemAnchor25"></a>
<span class="question top_question">14. Life policy purchase evaluations include which of the following (choose all that apply):&nbsp;<b class="icon_required" style="color:#FF0000">*</b></span>
<table class="inline_grid">
<tbody><tr>
<td><input type="checkbox" name="RESULT_CheckBox-25" class="multiple_choice" id="RESULT_CheckBox-25_0" value="CheckBox-0" readonly=""><label for="RESULT_CheckBox-25_0">Insured’s credit rating</label></td>
</tr>
<tr>
<td><input type="checkbox" name="RESULT_CheckBox-25" class="multiple_choice" id="RESULT_CheckBox-25_1" value="CheckBox-1" readonly=""><label for="RESULT_CheckBox-25_1">Employment history</label></td>
</tr>
<tr>
<td><input type="checkbox" name="RESULT_CheckBox-25" class="multiple_choice" id="RESULT_CheckBox-25_2" value="CheckBox-2" readonly=""><label for="RESULT_CheckBox-25_2">Medical records</label></td>
</tr>
<tr>
<td><input type="checkbox" name="RESULT_CheckBox-25" class="multiple_choice" id="RESULT_CheckBox-25_3" value="CheckBox-3" readonly=""><label for="RESULT_CheckBox-25_3">Insurer’s credit rating</label></td>
</tr>
</tbody></table>
</div>

$(document).ready(function(){

Answer 1

I was able to come up with the answer this morning.

My problem was on this for loop, I'm looping through the answers, which I passed 23, if I chose 2 and 4 (or in the fiddle, 1 and 3). Then it responded as correct, because on the last iteration it would find that the last checkbox was check and 2 checkboxes were checked.

for(p=0; p < answers.length; p++){

     var selected = [];
     $("input[name='"+question+"']").filter(":checked").each(function() {

        if(question+"_"+answers[p] == $(this).attr('id') && $("input[name='"+question+"']").filter(":checked").length == answers.length){
           $("#"+parentDiv+"_success").show();
           $("#"+parentDiv+"_fail").hide();
        } 
        else {
           $("#"+parentDiv+"_success").hide();
           $("#"+parentDiv+"_fail").show();
        }

     });

} //end for loop

My Solution was to Iterate through which checkboxes are checked and return the combined index of which was checked and compare that to the answers.

EG I pass '23', they check '1' and '4', '14' != '23', so incorrect.

$("#"+parentDiv+"_confirm").on("click keypress", function(){

  $("input[name='"+question+"']").prop('readonly', true);

  var answers = correctNumber[i];

  var input = "";

  $("input[name='"+question+"']").each(function(t){

      if($(this).is(':checked')){
          input = ""+input+t;
      }

  });

  if(input == answers){
      $("#"+parentDiv+"_success").show();
      $("#"+parentDiv+"_fail").hide();
  } 
  else {
      $("#"+parentDiv+"_success").hide();
      $("#"+parentDiv+"_fail").show();
  }


}); //end on click/keypress
