AngularJS update JSON file

Question

I have a JSON file in my server and an angularJS code that reads it like this:

 $http.get('route/to/json/file.json').success(function(data) {

            $scope.watchesdata = data;

            var tmpList = [];

            for (var i = 0; i <= limit; i++){
            tmpList.push({
                Time: $scope.watchesdata[i].balance,
                Company : $scope.watchesdata[i].company,
                Matter: $scope.watchesdata[i].address
            });
          }  

            $scope.list = tmpList;    

        });

After some more code that is not important, I update an specific 'Time' value and i want the JSON file on my server to update its information too, something like :

"If company==something and matter==something then oldTime = newTime"

I've just found how to add data at the end of a JSON, but i need to look for a specific entry and modify just one field.

you need to use server code to update file. Strongly suggest you use a database or data storage service rather than manage your own in hard files. — charlietfl

"I've just found how to add data at the end of a JSON" if you can add it to the end, surely you can figure out how to add it to the middle (assuming you're actually adding it to the end in a way that results in valid json) — user400654

Assuming I'm understanding your question correctly, something like this would work:

function updateTime(company, matter, newTime) {
    $scope.list.forEach(function (item) {
        if (item.Company == company && item.Matter == matter) {
            item.Time = newTime;
        };
    });
};

You would have to POST this data back to your server, as JSON, to update your server side though. It's unclear if you are asking how to do that part too.
