How to pass PHP/html to javascript loop

Question

I have a pretty robust JavaScript script that controls my room lights via some external software. I have a PHP that when run returns only a 1 or a 0. I ideally want to have a JavaScript loop that runs every couple seconds and pulls that 1 or 0 and if it is a 1, do some work. Problem is, can't figure out how to get the JavaScript to open another page in terms or processing/data collection.

Is there a "file get contents" equal to JavaScript? I don't want the PHP values written on the JavaScript page, just to have the value to do a little if statement.

You want an [AJAX](http://api.jquery.com/jQuery.ajax/) call. — Marc B, Nov 15 '13 at 15:13

As @Marc B said, you want to make AJAX calls. Here is a idea in how to implement it using jQuery.

<script>
    function updateData(){
      $.get( "ajax/test.html", function( data ) {
        //now "data" has the response 
      });
    }

    setInterval(updateData, updateInterval);
</script>
