How to put PHP echo code into JavaScript?

Example:

 value: <?php echo 'Hello World!' ?>
 min: 0,
 max: 100,
 title: "Target",

Answer 1

You just missed the quotation around the <?php & semi-colon before ?>,

document.addEventListener("DOMContentLoaded", function(event) {
 var gg1 = new JustGage({
 id: "gg1",
 value: "<?php echo 'Hello World!'; ?>", // This line is edited
 min: 0,
 max: 100,
 title: "Target",

• dale landry: Also missed basic syntax like the semi-colon to end your echo string, 'Hello World!' should be 'Hello World!'; If you have it turned on in your php.ini file, you can also use ' <?=$variable?> '.

In order to use Php varibale inside Javascript or JQuery call them like this..

var example ="<?php echo date();?>";
