I used the below snippet

$(this).text($(this).text().replace(old_word, new_word));

with $(this) being the object containing the text you want to replace

Alright, this snippet will do it:

$('body, body *')
    .contents()
    .filter(function() {
        return this.nodeType == Node.TEXT_NODE
            && this.nodeValue.indexOf('Hello') >= 0;
    }).each(function() {
        this.nodeValue = this.nodeValue.replace(/\bHello\b/g, 'Welcome');
    });

I really wouldn't recommend using it, but it's nice to know it's possible in a pinch.

It works by finding all the text nodes that have 'Hello' in them, then uses a regular expression to do a global replace on the word 'Hello' with 'Welcome' for each of those text nodes.

Might've found something which would be better than our hacked attempted above.

Have a look :)

edit: here is its working page: http://benalman.com/code/projects/jquery-replacetext/examples/replacetext/

Apparently they went down the same route as us but have spent more time on it and it's well, complete :D

$(document).ready( function() {
$('.title').html('Welcome');
});

I'm guessing here that it is in a tag, on its own. If you need more than that (Hello being part of a sentence) then you'll need to use something like $('.title').replace('Hello','Welcome')

Edit: This is my current train of thought, I'm a bit busy so I thought I would throw it down just in case you can slot the last piece in:

function scanReplace($element) {
    $element.children().each(function() {
        var $this = $(this);
        $this.text().replace('Hello','Welcome');
        if ( $this.children().length > 0 ) scanReplace($this);
    });
}

scanReplace($('body'));

You can replace it with the .replace function. Only the word that you want to replace has to be in a string.

var old_line = "Hello World!";
var new_line = old_line.replace('World', 'Stackoverflow');

You can also replace multi words like:

var old_line = "Hello World! Hello World! Hello World! Hello World!";
var new_line = old_line.replace(/World/gi, 'Stackoverflow');
alert(new_line); //Output: Hello Stackoverflow! Hello Stackoverflow! Hello Stackoverflow! Hello Stackoverflow!

Permanently? You're better off just doing a search and replace across multiple files.
