javascript - Regex: Replace foo if it's a word or inside a URL -


given this:

str = "foo myfoo http://thefoobar.com/food awesome"; str.replace(magicalregex, 'bar');

the expected result is:

"bar myfoo http://thebarbar.com/bard awesome"

i \b(foo)\b part, can't figure out how match , capture foo within url. these purposes, assume urls start http.

any help?

you can use code (works example haven't tried more complex inputs):

str = 'foo myfoo http://thefoobar.com/food awesome'; str = str.replace(/\bfoo\b/g, 'bar'); while (/http:\/\/[^\s]*?foo/.test(str))     str = str.replace(/(http:\/\/[^\s]*?)?foo/g, function($0, $1) {         return $1 ? $1 + 'bar' : $0;     }); console.log(str);

output:

bar myfoo http://thebarbar.com/bard awesome

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
