Add an extra row before a sub question in a grid
In order to categorize sub questions in a grid question
As a questionnaire creator
I want to add extra rows to the grid
Example
I have a single grid question.
I want to have an extra row to group some sub questions together.
Solution
- Add a Single grid question to Questionnaire editor
- Go to menu Properties -> Question scripts -> Add code to Java script tab
Code
//add a row before a sub question in the grid
//subQuestionIndex: the index of sub question which we should add a row before
//cssClass: the stylesheet that would be applied to the new row
//text: name of the sub question group
//includeAnswerOptionTexts: if it is true, answer option texts will be included in the new row
quest.addRowBefore = function(subQuestionIndex, cssClass, text, includeAnswerOptionTexts)
{
//get number of columns
var n = $(".grid_inner")[0].rows[0].cells.length;
$(".grid_inner").find("tr").each(
function(i)
{
if (i == subQuestionIndex + 1)
{
if (!includeAnswerOptionTexts)
{
$(this).before( $("<tr>")
.append($("<td colspan="+n+">").text(text).addClass(cssClass))
);
}
else
{
var tr = $("<tr>").append($("<td>").text(text).addClass(cssClass));
for (var j=0; j<quest.questions[0].options.length; j++)
{
tr.append($("<td>").text(quest.questions[0].options[j].text).addClass(cssClass));
}
$(this).before(tr);
}
}
}
)
}
quest.onInit = function()
{
//insert a cell before Don't know on header
var dontKnow_value = 3;
this.addRowBefore(2, "extra_row_header", "Alcohol drinks", true);
}
