I am working on a design for a question where a participant will type a number in the textbox. Then, a percentage number “(Input_number-210)/210” will appear below the text box.
The following is the basic question:
The current price is $210.
What price do you want to offer?
(After you type the number, the change percentage will appear below. )
The following is theJavascript I tried. It shows nothing. Three things that I am not sure:
(1) Can we show the percentage after there is a number in the input box, within the same page, even the some block?
(2) There are a few function in the Javascript box. I am not sure which one to choose, or more than one needed?
(3) How to let the percentage number show right below the input box?
I would really appreciate your help! Thank you so much!
Qualtrics.SurveyEngine.addOnload(function()
{
function calc(){
var disc = 0;
var cp =getVal(parseInt($jq('input[type="number"]').eq(0).val()));
if (cp>0)
{
change_p = Math.round(((cp - 210)/210)*100,2);
}
return change_p; };
});
