jquery - Change countdown timer text once value is negative -

i have countdown timer counts down days. works fine want such that, values reach negative, text changes "days left" "days since" , removes negative sign.

how can achieve this?

fiddle:

jquery:

// set date we're counting down var target_date = new date("aug 15, 2013").gettime();  // variables time units var days, hours, minutes, seconds;  // tag element var countdown =  document.getelementbyid("ribboncountdown"); var days_span = document.createelement("span"); days_span.classname = 'days'; countdown.appendchild(days_span);  // update tag id "countdown" every 1 second setinterval(function () {  // find amount of "seconds" between , target var current_date = new date().gettime(); var seconds_left = (target_date - current_date) / 1000;  // time calculations days = parseint(seconds_left / 86400); seconds_left = seconds_left % 86400;   // format countdown string + set tag value.  days_span.innerhtml = '<span>' + days + '</span>' + 'days go';   //ribboncountdown.innerhtml = days + "d,;    }, 1000); 

update text based on whether days negative:

if (days < 0) {     days_span.innerhtml = '<span>' + days * -1 + '</span>' + ' days since'; } else {     days_span.innerhtml = '<span>' + days + '</span>' + ' days go'; }

or can simplify this:

var suffix; if (days < 0) {     days = days * -1;     suffix = ' days since'; } else {     suffix = ' days go'; } days_span.innerhtml = '<span>' + days + '</span>' + suffix;
