正则表达式javascript插入空格

Question

I have this regular expression in my javascript:

var name = '#tee name test ';
var title = name.replace(/[^a-z0-9]/gi,'');

This generate this title:

teenametest

But I'd want this:

tee name test

How can I allow space but remove other characters like '#'? Thanks

Change this line:

var title = name.replace(/[^a-z0-9]/gi,'');

To this:

var title = name.replace(/[^a-z0-9\s]/gi,'');

You need to tell the regex not to replace the spaces.

If you need to remove the last space, you can use the string.trim function.

If you still want to use regex to remove the last space as well, you can use:

var title = name.replace(/[^a-z0-9\s]|\s+$/gi,'');
