Scripting curiosum?

[Anonymous]

Hi,

I have been working on a script, and I ran into yet another scripting curiosum (for me at least).

I made this little test to show...

Now if I do my math correctly, I would expect the result to be 108 (9*12) but instead it comes to 918 (9*102)?

It of course has to do with line 10 in my script, where I expected distance to become 12 (the value of item.TAL_2 + 2) not 102??

I tried changing the script so I could run it as a normal Javascript in Chrome, and here it comes out with 108 - so what am I missing?

Best regards from Denmark

The distance is coming in as a string. This code:

 distance + 2

is concatenating "2" to the string "10", thus "102". What you need to do is convert distance to an integer. You should be able to say

distance = Number(distance);

at the top of the function to fix this. You might want to do the same to the speed variable just in case.

Here's a little explanation I did in a firefox console
