js parseInt("08") does not specify carry system problem
Updated: June 19, 2010 12:39:40 Author:
Today, I am making JS judgment about the month. I can get the correct result for parseInt("01") to parseInt("07"); but if it is parseInt("08") or parseInt("09"), it returns 0. First, look at parseInt syntax: parseInt(string, radix);
where string is the string to be converted, and radix is binary, octal, hexadecimal or decimal.
When radix is not specified by default, when the 0x switch is switched, it is hexadecimal; if the 0 switch is switched and the second bit is not x, then it is octal (because the octal cannot have 8, 9, an error returns 0).
Therefore, when we use it, we should clearly specify the carry system to prevent errors.
If we usually use decimal bits, we will parseInt("08", 10);
