Id is passed from JavaScript code as 338 correctly. Why does it show as 152? This isn't allowing me to get the proper data. Ideas?

Answer 1

The number is displayed as hexadecimal, you can see this by the 0x.... . Hex 152 is Dec 338.

Answer 2

Id以十六进制表示（以0x开头），0x152等于338。

Answer 3

This is hexadecimal. It's the same number

0 = 0
1 = 1
2 = 2
3 = 3
4 = 4
5 = 5
6 = 6
7 = 7
8 = 8
9 = 9
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15

Computers LOVE binary. So representing numbers in bases that of the form 2^n is awesome for working with computers ;)
