If you have a PHP Array and want to perform some javascript operations by looping the PHP Array, then I recommend you to use PHP foreach loop instead of Javascript forEach loop.
function myfunction() { <?php foreach($myArray as $val) { ?> console.log('<?=$val;?>'); <?php } ?> }
Here is a full code to print contents of a div using javascript. Just create a div and give any id to it and then create an anchor tag as given below :
<a href="javascript:void(0);" onclick="printdiv('IDOFDIV')">Print</a>
After creating this anchor tag put the below javascript code in your page.
function printdiv(printpage) { var newstr = document.getElementById(printpage).innerHTML; var oldstr = document.body.innerHTML; document.body.innerHTML =newstr; window.print(); document.body.innerHTML = oldstr; return false; }
Here is the full javascript tutorial for creating a countdown timer to a certain date. This count down timer contains days, hours, minutes and seconds as well.
// Set the date to which the timer continues var countDownDate = new Date("Aug 1, 2017 12:00:00").getTime(); var x = setInterval(function() { // Todays date and time var now = new Date().getTime(); // Distance between now and the countdown date var distance = countDownDate - now; var days = Math.floor(distance / (1000 * 60 * 60 * 24)); var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60)); var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60)); var seconds = Math.floor((distance % (1000 * 60)) / 1000); // Putting the countdown timer in element with ID demo document.getElementById("demo").innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s "; // If countdown is over, then putting the text in element with ID demo if (distance < 0) { clearInterval(x); document.getElementById("demo").innerHTML = "EXPIRED"; } }, 1000);
One more thing to do, just place the below code in your body :
