JS (remove the front and back spaces or remove all spaces) usage

1. Remove all spaces before and after the string:

The code is as follows:

12         return""3  }

Description:

If you use jquery to directly use the $. Trim(str) method, str indicates that you want to remove all the spaces before and after the string.

2, remove all the spaces in the string (including the middle space, you need to set the 2nd parameter is: g)

The code is as follows:

1 function Trim (str,is_global) {2         varresult;3result = Str.replace (/(^\s+) | ( \s+$)/g,"");4         if(is_global.tolowercase () = ="g") {5result = Result.replace (/\s/g,"");6         }7         returnresult;8}
