JS var在WP中获取PHP值

Question

I was reading all similar questions and answers around, but none seem to work for me.

i have this:

<script>
var MyCity  = "<?php echo 'Cityville';?>";
</script>

but this outputs the entire php. I also tried this:

<?php echo json_encode('City'); ?>

all these in a WP widget.

any ideas?

thank you!

The issue is that you have quotes around your echo statement, you need to have them around your variable AFTER it has been output to function within the script, like so:

<script>
    var MyCity  = <?php echo '"Cityville"';?>;
</script>
