Read multiple JSON API Pages and parse data

Question

Objective: To collect JSON data from forecast API and then read the JSON precipIntensity property over the number of days specified, this code starts at three. Since this take a number of steps to coherently follow please try to make sense of all the code.

My main issue is trying to name the JSON code pages that return then put them into another context to read the precipIntensity property.

To outline: The back date gets the UNIX time, then requests an API for each forecast day. Then the APIs are put in an array. The array is put in a for() loop to request each JSON script... (now what to do? I would like to be able to read each or calculate something but I do not know how to ask for the formatted code. I can do the remaining bit). A sample of JSON can be found at my other related post... https://stackoverflow.com/questions/29949454/store-json-api-object-data-and-reuse-it (I found that the API server stores the data for me...solved) EDITED since 5/1/15:

    //Get the back dated times and current in UNIX, 
   //later make a lookup that gives datediff from current date and user's date and adjust index i condition to equal exact days.
            var totalPrecipSinceDate;
            var threeDayAPITimes = [];

            for (var i = 0; i <= 2; i++) //place user userData-1 where i <= input
        {
            var myDate = new Date(); //https://stackoverflow.com/questions/7693170/javascript-convert-from-epoch-string-to-date-object
            var epoch = myDate.getTime(); //1318023197289 number of ms since epoch
            var unixEpoch = Math.round(epoch/1000)
            threeDayAPITimes[i] = Math.round(unixEpoch - (86400 * i));
                /*
                var epoch = (DateTime.UtcNow - new DateTime(1970, 1, 1)).TotalSeconds;
                threeDayAPITimes[i] = Math.round(epoch - (86400 * i));
                */
        }
        //Plan to convert UNIX dates to display

        //List of locations: LATITUDE,LONGITUDE
        var locations = ["46.3494,-85.5083"]

        var currentAPIKey ="privateAPIKey"; //gets an APIkey from user from forecaster input.

 var listAPIs = "";

$.each(threeDayAPITimes, function(i, time) {
    var darkForecastAPI= "https://api.forecast.io/forecast/" + currentAPIKey + "/" + locations + "," + time;
    $.getJSON(darkForecastAPI, {
        tags: "WxAPI[" + i + "]",  //Is this tag the name of each JSON page? I tried to index it incase this is how to refer to the JSON formatted code from the APIs.
        tagmode: "any",
        format: "json"
    }, function(result) {
        // Process the result object
    });
    });
  //Process result in foreach loop   
         var eachPrecipSum = 0;
    if(result.currently.precipIntensity >=0 && result.currently.precipType == "rain")
        {
            $.each(result, function() {
              eachPrecipSum += (this.currently.precipIntensity);
              totalPrecipSinceDate += eachPrecipSum ;
        });

        }       
            alert(eachPrecipSum );

Answer 1

Your loop should be something like this:

$.each(threeDayAPITimes, function(i, time) {
    var darkForecastAPI= "https://api.forecast.io/forecast/" + currentAPIKey + "/" + locations + "," + time;
    $.getJSON(darkForecastAPI, {
        tags: "WxAPI[" + i + "]",  //Is this tag the name of each JSON page? I tried to index it incase this is how to refer to the JSON formatted code from the APIs.
        tagmode: "any",
        format: "json"
    }, function(result) {
        // Process the result object
    });
}
