Answer 1

You can use trim for such things. http://www.w3schools.com/jsref/jsref_trim_string.asp

Answer 2

To remove whitespace from the beginning of a line, use

.replace(/^[^\S\r\n]+/gm, "")

Pattern details:

• ^ - start of a line (since multiline modifier /m is used)
• [^\\S\\r\\n] - matches any character other than a nonwhitespace, carriage return and line feed characters. + makes it match one or more occurrences.

Answer 3

try this

var text = "          this is a string         \n"+
       "    \t    with a much of new lines     \n";
text.replace(/^\s*/gm, '');

Regular expression to remove space in the beginning of each line?
