Trim a string with all types of spaces
August 2, 2007 · Posted in javascript
var a = “151 “;
a = a.replace(/^\s+|\s+$/, “”);
//a is now “151″ .
Note:
\s : Matches a single white space character, including space, tab, form feed, line feed.
Equivalent to [ \f\n\r\t\v\u00A0\u2028\u2029].
\S: Matches a single character other than white space.
Equivalent to [^ \f\n\r\t\v\u00A0\u2028\u2029].
