Both horizontal and vertical single grid

Chalenge :

There are a single grid question . Respondents should prioritize statements (sub questions) .

Example :

I have a list of trade-mark and want the user to prioritize those list :

Dell

Apple

IBM

FPT Elead

Solution :

Use single grid question (statements as subquestion and ranks as answer option )

Code

The script makes a single grid question function as a single grid both horizontally and vertically.

option.prototype.getHTML = function(ltype) {

var stmp = "";

if(this.visible) {

switch(ltype) {

case 2:

stmp += "<input type=\"radio\" ";

stmp += "name=\""+this.label+"\" ";

stmp += "value=\""+this.value+"\" ";

if(this.checked) stmp += "checked ";

if(this.disabled) stmp += "disabled ";

stmp += "onclick=\"myoptclick('"+this.label+"',"+this.index+",false);\">";

return "<td valign=\"center\" align=\""+this.align+"\">"+stmp+"</td>";;

break;

}
