Automatically calculate percentage within a Survey from two price fields within the same question | XM Community
Skip to main content
Is it possible within a Survey question to have three fields: Current Price, Sale Price, and Percentage off but have the Percentage off field be populated in real time from the current price and sale price inputs? A Qualtrics support agent stated it may be possible with Javascript but I have limited experience with Javascript and want to ensure it is possible?
Hi @bonjessi,



I have calculated the discount % in attached QSF file using Javascript. Below is the Code.



var $jq= jQuery.noConflict();

$jq('.SumInput:last').attr('readonly',true);

$jq('.SumInput').keyup(function(){

$jq('.SumInput:last').val(calc());

});





function calc(){ var disc = 0;

var cp =getVal(parseInt($jq('.SumInput').eq(0).val()));

var sp =getVal(parseInt($jq('.SumInput').eq(1).val()));

if (cp>sp && sp>0)

{

disc = Math.round(((cp - sp)/cp)*100,2);

}

return disc; };



function getVal(val){ var fval=0;

if (isNaN(parseInt(val)))

{ fval = 0; } else { fval = val; }

return fval;

}





Hope this works for you!



Regard,

Samarth
