Send the JSON to a PHP script on the server using AJAX. The script decodes the JSON, verifies it looks good according to whatever criteria you haven't mentioned are important for this JSON, and then encodes and saves.

thanks for helping it works now i got 1 more question:

i have to use ajax i think the (post methode) what i try to do is the lane 1 2 3 4 is now on 1 1 5 2 but what i want is that if i press on one button that it will be stored on the button I last clicked on. do you know how to use this and where i have to put it in de code?

 

 //jsonfile = '[{"lane 1":"1","lane 2":"1","lane 3":"5","lane 4":"2"}]';
    var jsonRequest = new XMLHttpRequest();
    jsonRequest.onreadystatechange = function () {
        if (jsonRequest.readyState == 4 && jsonRequest.status == 200) {
            var initialstate = JSON.parse(jsonRequest.responseText);
            setLaneStates(initialstate);
            console.log('Done loading JSON data');
        } else {
            console.log('Failed to get JSON data');
        }
    }
    jsonRequest.open( "GET", "data.json", true);
    jsonRequest.send( null );

I'm sorry, but what? I'm not trying to be an ass, but take a breath, step back, and describe what you want to do one simple step at a time. Write out the pseudo-code, then post it here.
