echo a php variable which is inside a javascript function which is inside a php

Question

This snippet is of jQuery code is inside the php already...How do I access variables inside the jquery code

<?php


echo'
    $( "#searchButton" ).click(function() {


    //    location.reload();
    alert(\"$folder\"); //This is causing error
    });'

?>

Try echoing the variable there instead of just printing the string name of the variable? — CertainPerformance, Nov 28 '18 at 07:19

@SougataBose yup – MrRobot9 Nov 28 '18 at 07:26
`alert("");` would work. – Sougata Bose Nov 28 '18 at 07:27

@SougataBose `' . $folder .' = $( "#search" ).val();` initializing a variable like this doesnt work though – MrRobot9 Nov 28 '18 at 07:49

try this as echo will return a value to the alert.

alert(<?php echo $folder ?>);
