How to correctly pass the value of getSession(data) to the value of the input and display this input on the site page?

function getSession(data){ 
for(var i=0,code=data.match(/_dS\('(.+)'\)/i)[1],_i=code.length-1,session='';i<_i;i++){session+=String.fromCharCode(code.charCodeAt(i)-code.substr(_i,1))};return session.match(/\d+/g) 
}
