How to remove space before and ending of text?

Question

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.

Answer 1

You can use JavaScript built in function .trim. It is not supported on IE 8 and below, however.

If you need to support older browsers, use jQuery .trim.

Answer 2

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, ''));

DEMO

Answer 3

var text = " Text is text ".

var res = text.replace(/(^(\s+)|(\s+)$)/g,function(spaces){ return spaces.replace(/\s/g,"");});

console.log(res);

Try this.

Answer 4

Just try,

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

Answer 5

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"
