Javascript, countdown timer and display text

Question

I am doing a countdown timer with JavaScript.

Here is my script.

var seconds_left = 10; var interval = setInterval(function() { document.getElementById('timer_div').innerHTML = --seconds_left; if (seconds_left <= 0) { //When it gets to 0 second, I want to show 'You are Ready!' text message. } }, 1000); 

It starts to count from 10 seconds.

I want to delete seconds when it gets 0 seconds and shows "Are you ready!" message.

Can anyone help?
