Alternating Row Background Colors for Matrix Question not including Statement Group Headers

Try below code:

jQuery(".ChoiceRow.ReadableAlt").each(function(){if(jQuery(this).find(".Group").length==0)jQuery(this).css("background","#d9d9d9");});

jQuery(".ChoiceRow.ReadableAlt").each(function(){if(jQuery(this).find(".Group").length==0)jQuery(this).css("background","#d9d9d9");});

Thank you this worked! Do you know if there is a way to select a second background color to alternate? Moreover, I’m finding each group starts with a different color each time, is there a way to make each group start with the same color every time? @Shashi 

jQuery(".ChoiceRow.ReadableAlt").each(function(){if(jQuery(this).find(".Group").length==0)jQuery(this).css("background","#d9d9d9");});

Try this:

var f;
	jQuery("#"+this.questionId+" th.Group").each(function(){
		f=1;
		jQuery(this).parent().nextAll(".ChoiceRow").each(function(i){
			if(jQuery(this).find("th.Group").length==0){
				if( i%2==0 && f==1)
					jQuery(this).css("background","#d9d9d9");
			}else
					f=0;

		});

	});

jQuery(".ChoiceRow.ReadableAlt").each(function(){if(jQuery(this).find(".Group").length==0)jQuery(this).css("background","#d9d9d9");});

var f;
	jQuery("#"+this.questionId+" th.Group").each(function(){
		f=1;
		jQuery(this).parent().nextAll(".ChoiceRow").each(function(i){
			if(jQuery(this).find("th.Group").length==0){
				if( i%2==0 && f==1)
					jQuery(this).css("background","#d9d9d9");
			}else
					f=0;

		});

	});

@Shashi this didn’t color any of the rows, should it be in addition to the previous code?

No, please attach screenshot where you have paste the code.

@Shashi 

Code should be pasted in the onload function like below:

@Shashi This worked!! Thank you so much!! One follow up question would be for the alternating colored rows, is there a way to set a second color to alternate between other than white for the rows, not including the group headers, and having the statements within each group both start on the same first color?

Try this:

	var f;
	jQuery("#"+this.questionId+" th.Group").each(function(){
		f=1;
		jQuery(this).parent().nextAll(".ChoiceRow").each(function(i){
			if(jQuery(this).find("th.Group").length==0){
				if( i%2==0 && f==1)
					jQuery(this).css("background","#d9d9d9");
				else
					jQuery(this).css("background","#c4acac");
			}else
					f=0;

		});

	});

	var f;
	jQuery("#"+this.questionId+" th.Group").each(function(){
		f=1;
		jQuery(this).parent().nextAll(".ChoiceRow").each(function(i){
			if(jQuery(this).find("th.Group").length==0){
				if( i%2==0 && f==1)
					jQuery(this).css("background","#d9d9d9");
				else
					jQuery(this).css("background","#c4acac");
			}else
					f=0;

		});

	});

Worked! Thank you so much for all your help! @sha
