jQuery/JavaScript string replace a specific word and all characters after it

Question

How can I remove spaces, a keyword, and everything after it? Here's what I'm looking for

var test = $('.replaceMe').attr('title').replace(/ /g, '');

<a class="replaceMe" href="#" title="Replace By Everything After It">haha</a>

resulting in:

test = Replace;

UPDATE:

The keyword is a yet-to-be-determined word that will be included in all titles. In this example, it is "By".

Both Roko and user1215106's answers work- in that they remove all the excess from the example, leaving Replace, but I failed to clarify that the phrase before the keyword (in this case, Replace) will vary and will have differing amounts of words.

For example:

title="Replace By Everything After It"

Result= Replace

title="All This Should Stay By Things That Should Go"

Result= AllThisShouldStay

Do you want to retrieve the first word of the title attribute as a string? — Šime Vidas

jsFiddle demo

var keyword = 'By';

var test = $('.replaceMe').attr('title').split(keyword)[0].replace(/ /g, '') ;

Or instead of having the keyword variable you can do:

var test = $('.replaceMe').attr('title').split('By')[0].replace(/ /g, '') ;

not quite, i'll elaborate above. the phrase before "by" (or whatever the keyword ends up being) varies.

@technopeasant so... (in your 2. example) your keyword is actually the word By, right?

@technopeasant :) there you go! I reedited my answer and the demo

Roko C. Buljan Over a year ago

@technopeasant so actually you were very close, you just missed this: .split('By')[0]

var test = $('.replaceMe').attr('title').replace(/\s+by\s.*/, '').replace(/\s+/. '');

Let key be the keyword you want to find.

escapedKey = key.replace(/([-$^&*()\/\\+?.\[\]{}|])/g, "\\$1");
$('.replaceMe').attr('title').replace(new RegExp(escapedKey + ".*"), "")

I tried to generalize for arbitrary keyword, but not yet tested for everything.
