Using "GET" command in JavaScript as an "If/Else"

Jesse Teindl

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 a platform 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!

Hi,

You can define a variable and set value of that variable as true/ false based on the return value of API.

Then you can set that variable directly in your given function -

stop = new google.maps.LatLng(49.093914487013, -117.71569423377514)
waypts.push({
location: stop,
stopover: yourvariablename

Have you tried creating a function that would return a boolean (true/false)? The function will contain your AJAX call and then you implement the logic to return a boolean within that function. You could then assign the function to a variable and use it as your "stopover" parameter.

That's kind of what I'm hoping to do. That would be easier and a bit more organized. So how would I do that? I need to define the value of (thingspeakapistring) as a var? and then on this:

stop = new google.maps.LatLng(49.093914487013, -117.71569423377514)
waypts.push({
location: stop,
stopover: true

How would I put, if (result of defined variable) is >8 statement is true, else False

Hi,

Is there any problem calling the API as a separate function before the given scripts and setting a global boolean variable based on the result and assign that variable to stopover?
