My app is going to work in multiple env, in which i need to get the common value (base url for my app) to work across..
from my window location how to i get certain part from the start..
example :
http://xxxxx.yyyy.xxxxx.com:14567/yx/someother/foldername/index.html
how can i get only:
http://xxxxx.yyyy.xxxxx.com:14567/yx/
my try :
var base = \w([yx]/)
the base only select yx/ how to get the value in front of this?
this part..
thanks in advance..
If 'someother' is known to be the root of your site, then replace
\w([yx]/)
with
(.*\/)someother\/
(note that the / characters are escaped here) which gives a first match of:
http://xxxxx.yyyy.xxxxx.com:14567/yx/
However, a regular expression may not be the best way of doing this; see if there's any way you can pass the base URL in by another manner, for example from the code running behind the page.
If you don't mind disregarding the trailing slash, you can do it without a regex:
var url = 'http://xxxxx.yyyy.xxxxx.com:14567/yx/someother/foldername/index.html';
url.split('/', 4).join('/');
//-> "http://xxxxx.yyyy.xxxxx.com:14567/yx"
If you want the trailing slash, it's easy to append with + '/'.
Please try following regexp:
http\:\/\/[\w\.]+\:\d+\/\w+\/
This one should do pretty well
http:\/\/[\w\.]+\:\d+\/\w+\/
Perhaps something like this?
Javascript
function myBase(url, baseString) {
if (url && baseString) {
var array = url.split(new RegExp("\\b" + baseString + "\\b"));
if (array.length === 2) {
return array[0] + baseString + "/";
}
}
return null;
}
var testUrl = "http://xxxxx.yyyy.xxxxx.com:14567/yx/someother/foldername/index.html",
testBase = "yx";
console.log(myBase(testUrl, testBase))
;
Output
http://xxxxx.yyyy.xxxxx.com:14567/yx/
