Not sure if this is already doable...

 

In my JavaScript I have a number of variables as shown:
 
stop = new google.maps.LatLng(49.093914487013, -117.71569423377514)
waypts.push({
location: stop,
stopover: true
 
The line in Bold is what I need help with. I have data transmitted to Thingspeak. I have an API that allows me to select the exact value to query; what I need to know is how to use a GET statement (Or anything that would work) to have that Stopover line be True or False based on the result. So IF the result queried by the API is over 8, it's TRUE, if it's under it is false.
 
The API line looks like this: 
 
GET https://api.thingspeak.com/channels/****/fields/1.json?results=2
So How do I set that Bold field to query this and either be TRUE or FALSE based upon the result of this query?
 
If you need any more info please reply and I can fill in any blanks, but I'm reallllly needing some help here.
 
Thank you!

You may be able to use jquery:

$.getJSON('https://api.thingspeak.com/channels/' + channel_id + '/fields/1.json?api_key=' + api_key , function(data) {

 

if (data.feeds==....)   //Do your check here

})

You may need to load the library first:
