For example : I have a string like that: " Text is text ".
Now i want to use Javascript to remove all space before and ending of that string to have result :
"Text is text".
How can I that with Javascript. Thank for your help.

Use String.trim (IE 9+ and normal browsers).
" my text ".trim(); // "my text"
To make sure it will work in all browsers you can use a regular expression:
var str, re; str = " my text "; re = /^\s+|\s+$/g; console.log(str.replace(re, ''));

You mean
String.prototype.trim(), String.trim() will give you TypeError.

I mean method
trim of class String.
var text = " Text is text ". var res = text.replace(/(^(\s+)|(\s+)$)/g,function(spaces){ return spaces.replace(/\s/g,"");}); console.log(res); Try this.

Just try,
var str = " Text is text "; str = str.replace(/(^\s+|\s+$)/g, '');

You can use str.trim() spaces at the end and beginning , if you want unwanted spaces in between words u can use regex to remove that
" my text ".trim(); => "my text" " my text".replace("/ {2,}/g"," "); => "my text" " my text ".trim().replace("/ {2,}/g"," "); => "my text"
