Add an extra row before a sub question in a grid

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);
}
