Question

    function f(){
    var x = document.getElementById("point").innerHTML;
    }

And if I pass x to the php file,how can I receive it?

Google "AJAX", that's really all you need to get fast information. — Charlotte Dunois, Jan 18 '16 at 11:30
ajax. Jquery example: `$.post('my.php', {x:x}, function(response){alert(response);});` php: `//my.php $x = $_POST['x']; echo 'value from js is: '.$x;` — Steve, Jan 18 '16 at 11:31

Try this one,

function f(){
    var x = document.getElementById("point").innerHTML;
    window.location.href = 'page.php?point='+x;
}

And in page page.php try this,

$point = $_GET["point"];

Sorry,I have already tried it but the chrome echoed an error that "Uncaught ReferenceError: windows is not defined" to me. – wind910037 Jan 18 '16 at 12:25
@wind910037 : see my updated answer. change `windows` to `window`. It's my mistake. – Jithin Varghese Jan 18 '16 at 13:24

The only to do so is by making an ajax request. For more info on making an ajax request, refer this

Try This out:

function myFunction() {var javascriptVariable =document.getElementById("point").innerHTML;window.location.href = "myphpfile.php?name=" + javascriptVariable; }

On your myphpfile.php you can use $_GET['name'] after your javascript was executed.
