Reverse single grid between sub questions and answer options

Challenge

Client would like to show Sub-Questions and Answer Options inversly on Single-Grid. Therefore, we have to reverse the columns and rows on Single-grid. By the way, we have to change the radio buttons accordingly.

Example

We have the original Single Grid like this:

After reversing, we have a Single Grid like this:

Solution

1. Reverse Sub-Questions' names and Answer Options' names.
2. Rearrange the radio buttons accordingly.

Code

 1 var normaloptClick = optclick;
 2 this.optclick = function(slbl, lidx, blnk)
 3 {
 4    return normaloptClick(slbl, lidx, blnk);
 5 }
 6 
 7 quest.onInit = function()
 8 {
 9    var i,j; 
10    // declare variables
11    var mytable =  $("table[class='grid_inner']");
12    var numberOfQuestions = this.questions.length;
13    var numberOfAnswers = quest.questions[0].options.length;
14    // get all radio buttons in the Grid
15    var radioButtonsEven = $("td[class='grid_subquestion_even']");
16    var radioButtonsOdd = $("td[class='grid_subquestion_odd']");
17 
18 // ~~~~~~`swap column to row and inversely~~~~~~
19 
20 
21  
22 // swap radio buttons
23    var newTable = $("<table>");
24    var ao;
25    var sq; 
26    var aoName; 
27    var sqName;    
28    var firstRow = $("<tr>");
29    var posAo;
30    var posSq;
31    firstRow.append($(".grid_empty_cell"));
32    for(i=0;i<numberOfQuestions;i++)
33    {
34       posAo = i + 1;
35       sqName = "td[id='grid_subquestion_text_" + posAo +"']";
36       sq =$(sqName);
37       firstRow.append(sq);
38    }
39    newTable.append(firstRow);
40       
41    var newTr;
42    for(i=0;i<numberOfAnswers;i++)
43    {
44       
45       posSq = i + 1;
46       aoName = "td[id='grid_answeroption_text_" + posSq +"']";
47       ao =$(aoName);
48       newTr = $('<tr>');
49       newTr.append(ao);
50       for(j=0;j<numberOfQuestions;j++)
51       {
52          if (j%2==0)
53          {
54             newTr.append(radioButtonsEven[Math.round(j/2)*numberOfAnswers+i]);
55          }
56          else
57             newTr.append(radioButtonsOdd[(Math.round(j/2)-1)*numberOfAnswers+i]);
58       }
59       newTable.append(newTr);
60       
61    }
62    newTable.append($("input[value='']"));
63    mytable.empty();
64    mytable.append(newTable.children()[0]);    
65    var ua = navigator.userAgent.toLowerCase(); 
66    if ( ua.indexOf( "firefox" ) == -1 && ua.indexOf( "safari" ) == -1) 
67    { 
68    $("#query").append("<INPUT id='dir' type=hidden name='dir'>");  
69    }
70 }
