Javascript code to remove the first character and the last character

Source: Internet

This article mainly introduces the implementation code for removing the first character and the last character from JS. If you need it, refer to it, I hope to help you with the "[lightinthebox]" character string, but I just need lightinthebox, that is, do not "[]". How can we remove it quickly and effectively.
StringObject. substring (start, stop) // captures the start and end strings.
StringObject. substr (start, length) // intercept the start and string length.
Considering this, it is related to methods.
StringObject. substr (1). substring (-) // It is feasible.
Here, by the way, there is a way to change a single position to two. For example, 9 is displayed as 09 to facilitate format alignment.
In many cases, you can determine whether the number is smaller than 10 to add 0.
If we use a string, we don't need to judge it. We just need to add one to all. We can just take the last two digits and 01,010,011 will become 01 10 011.
