echo a javascript variable

Question

What is the best way to echo the variable get_parestotal?

Some help please! Thank you

  <script type="text/javascript">
 $(document).ready(function(){
                    var get_parestotal = 0
                $(".parestotal").each(function(){
                    get_parestotal += parseFloat($(this).text());
                });
                alert(get_parestotal);

            });

</script>



<? echo json_encode($get_parestotal); ?>

You can't do that. But you can alert or console.log(get_parestotal) — andrex

the echo is in PHP server side, while the variable is on the client side... — fast

You want to output the info to the page? Than console.log is not what you want. Learn about innerHTML or appendChild. — epascarello

You can log variables and so on in the console.

e.g.:

console.log(get_parestotal);

You can even concatenate witht he use of + console.log('This is your variable'+get_parestotal)

You can even add styling to your log (color, background-color,...):

console.log('%cThis is your variable'+get_parestotal+'!','color:green;');

There are some alternatives to console.log() you could use:

 console.warn();
 console.info();
 console.error();
 console.debug();

You can also just use multiple arguments, ie console.log('bla', window, 123), if you use a good browser you can work with the output much better than as a string puu.sh/bJgmN/13103a5940.png

You can either do alert(myvar) or console.log(myvar).

Caveat: console.log is only supported in certain browsers...see the link.
