I was thinking that I don’t need to create more variables (yet), I was wondering if something along these lines would work to produce the same result.

function onSuccess(position)
{
$(‘#m1-Learning-textField1’).val(position.coords.latitude);
$(‘#m1-Learning-textField2’).val(position.coords.longitude);
$(‘#m1-Learning-textField3’).val(Math.round(position.coords.altitude));
$(‘#m1-Learning-textField7’).val((Math.COS(RADIANS(position.coords.latitude))*(1037.5646)));
}

as it turns out, in the Milestone TC it gives me another cheeseburger…

I think this might have something to do with a “Float” being my lat / lon is a decimal.

>p.s. Notify me when a reply is posted isn’t notifying me when replies are posted.

Did you enable the topic option be notified to response of your post? If yes, check your spam filter to ensure that replies are not being siphoned off to oblivion.

Also, does Math.COS() work for you? JavaScript is case sensitive and the function should be Math.cos().

Lastly, the cheeseburger issue has been resolved and will be in the next milestone, hopefully next week if all goes well.

I was looking at the trig functions and I think all of them said Math.COS() and No, that wasn’t working for me. So I think I’ll do it your way.

I was able to insert the variables but I think they are local. and Im not sure but I think the Math is going to have to be a global function.

I was trying to fire off the math from the (position.coords.latitude) and all I managed to do was screw up the entire function. So I took it out of the js.

Pretty much how I’m learning is trying things, running it, get the results, change it again, and again.

Finally, yeah I did set it to notify, I’ll check my spam filters

Keep the Cheesebuger, it lets me know I screwed something up.

function findPosition()
{
navigator.geolocation.getCurrentPosition(onSuccess, onError);
}
function onSuccess(position)

{
var lat = position.coords.latitude
var lon = position.coords.longitude
var alt = position.coords.altitude
$(‘#m1-Learning-latTxt’).text(lat.toFixed(8));
$(‘#m1-Learning-lonTxt’).text(lon.toFixed(8));
$(‘#m1-Learning-altTxt’).text(Math.round(alt));
}

What Im trying to get is:
$(‘#m1-Learning-hVelTxt).text(=COS(RADIANS(lat))*(1037.5646)toFixed(3));

Math.cos(lat*Math.PI/180)*1037.5646

180 degrees = PI radians

Stu,

Again you rock! I appreciate all of the direction on this. I would like to know if you have some suggestions as to where I can read up on some of these things like the Math.PI that you added. It seems that the Math.something needs to be in everything at every step when doing any Math function.

I’ll post a new topic, asking yet another question about some return.this but Im looking to get a better understanding rather than someone posting code for me.

But I don’t want anyone to think that I don’t appreciate everything that you guys have shown me.

That goes for “Doc Oct”, Wayne, 1TC and of course “UK” Stu.

Have a look at

Although w3schools have been ridiculed in the past for ‘schoolboy errors’ latterly I have found them to be a largely reliable source
