In joomla php there I can use $this->baseurl
to get the base path, but I wanted to get the base path in jquery.
The base path may be any of the following example:
http://www.example.com/
http://localhost/example
http://www.example.com/sub/example
The example
may also change.
This one will help you...
var getUrl = window.location;
var baseUrl = getUrl .protocol + "//" + getUrl.host + "/" + getUrl.pathname.split('/')[1];
I think it will ok for you
var base_url = window.location.origin;
var host = window.location.host;
var pathArray = window.location.pathname.split( '/' );
这将获得基本网址
var baseurl = window.location.origin+window.location.pathname;
This is an extremely old question, but here are the approaches I personally use ...
As many have already stated, this works for most situations.
var url = window.location.origin;
However, this simple approach can be used to strip off any port numbers.
var url = "http://" + location.host.split(":")[0];
Edit: To address the concern, posed by Jason Rice , the following can be used to automatically insert the correct protocol type ...
var url = window.location.protocol + "//" + location.host.split(":")[0];
As a bonus -- the base URL can then be redefined globally.
document.head.innerHTML = document.head.innerHTML + "<base href='" + url + "' />";
document.baseURI
返回基本 URL 也尊重<base/>

在 JavaScript 中获取基本 url 的最简单方法
window.location.origin
This is not possible from javascript, because this is a server-side property. Javascript on the client cannot know where joomla is installed. The best option is to somehow include the value of $this->baseurl
into the page javascript and then use this value ( phpBaseUrl
).
You can then build the url like this:
var loc = window.location;
var baseUrl = loc.protocol + "//" + loc.hostname + (loc.port? ":"+loc.port : "") + "/" + phpBaseUrl;
Had the same issue a while ago, my problem was, I simply needed the base url. There are a lot of detailed options here but to get around this, simply use the window.location
object. Actually type this in the browser console and hit enter to select your options there. Well for my case it was simply:
window.location.origin
var getUrl = window.location;
var baseurl = getUrl.origin; //or
var baseurl = getUrl.origin + '/' +getUrl.pathname.split('/')[1];
But you can't say that the baseurl() of CodeIgniter(or php joomla) will return the same value, as it is possible to change the baseurl in the .htaccess file of these frameworks.
For example :
If you have an .htaccess file like this in your localhost :
RewriteEngine on
RewriteBase /CodeIgniter/
RewriteCond $1 !^(index.php|resources|robots.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
The $this->baseurl() will return http://localhost/CodeIgniter/
I've run into this need on several Joomla project. The simplest way I've found to address is to add a hidden input field to my template:
<input type="hidden" id="baseurl" name="baseurl" value="<?php echo $this->baseurl; ?>" />
When I need the value in JavaScript:
var baseurl = document.getElementById('baseurl').value;
Not as fancy as using pure JavaScript but simple and gets the job done.
You can easily get it with:
var currentUrl = window.location.href;
or, if you want the original URL, use:
var originalUrl = window.location.origin;
Here's a short one:
const base = new URL('/', location.href).href; console.log(base);
I would recommend for everyone to create HTML base tag in development, then assign the href dynamically, so in production whatever host a client uses, it will automacically addapt to it:
<html>
<title>Some page title</titile>
<script type="text/javascript">
var head = document.getElementsByTagName('head')[0];
var base = document.createElement("base");
base.href = window.document.location.origin;
head.appendChild(base);
</script>
</head>
...
So if you are in localhot:8080, you will reach every linked or referenced file from the base, eg: http://localhost:8080/some/path/file.html
If you are in www.example.com, it will be http://www.example.com/some/path/file.html
Also note that, every location you're on, you should not use references like globs in hrefs, eg: Parent location causes http://localhost:8080/
not http://localhost:8080/some/path/
.
Pretent you reference all hyperlinks as full sentenced without the bas url.
The format is hostname/pathname/search
So the url is :
var url = window.location.hostname + window.location.pathname + window.location.hash
For your case
window.location.hostname = "stackoverflow.com"
window.location.pathname ="/questions/25203124/how-to-get-base-url-with-jquery-or-javascript"
window.location.hash = ""
So basically the baseurl = hostname = window.location.hostname
I am surprised that non of the answers consider the base url if it was set in <base>
tag. All current answers try to get the host name or server name or first part of address. This is the complete logic which also considers the <base>
tag (which may refer to another domain or protocol):
function getBaseURL(){
var elem=document.getElementsByTagName("base")[0];
if (typeof(elem) != 'undefined' && elem != null){
return elem.href;
}
return window.location.origin;
}
Jquery format:
function getBaseURL(){
if ($("base").length){
return $("base").attr("href");
}
return window.location.origin;
}
Without getting involved with the logic above, the shorthand solution which considers both <base>
tag and window.location.origin
:
Js:
var a=document.createElement("a");
a.href=".";
var baseURL= a.href;
Jquery:
var baseURL= $('<a href=".">')[0].href
Final note: for a local file in your computer (not on a host) the window.location.origin
only returns the file://
but the sorthand solution above returns the complete correct path.
window.location.origin+"/"+window.location.pathname.split('/')[1]+"/"+page+"/"+page+"_list.jsp"
与 Jenish 的答案几乎相同,但要短一些。
I was just on the same stage and this solution works for me
In the view
<?php
$document = JFactory::getDocument();
$document->addScriptDeclaration('var base = \''.JURI::base().'\'');
$document->addScript('components/com_name/js/filter.js');
?>
In js file you access base
as a variable for example in your scenario:
console.log(base) // will print
// http://www.example.com/
// http://localhost/example
// http://www.example.com/sub/example
I do not remember where I take this information to give credit, if I find it I will edit the answer
Easy
$('<img src=>')[0].src
Generates a img with empty src-name forces the browser to calculate the base-url by itself, no matter if you have /index.html
or anything else.
Here's something quick that also works with file://
URLs.
I came up with this one-liner:
[((1!=location.href.split(location.href.split("/").pop())[0].length?location.href.split(location.href.split("/").pop())[0]:(location.protocol,location.protocol+"//" + location.host+"/"))).replace(location.protocol+"//"+location.protocol+"//"+location.protocol+"://")]
var getUrl = window.location;
var baseUrl = getUrl .protocol + "//" + getUrl.host + "/" + getUrl.pathname.split('/')[1];
You mentioned that the example.com
may change so I suspect that actually you need the base url just to be able to use relative path notation for your scripts. In this particular case there is no need to use scripting - instead add the base tag to your header:
<head>
<base href="http://www.example.com/">
</head>
I usually generate the link via PHP.
In case anyone would like to see this broken out into a very robust function
function getBaseURL() {
var loc = window.location;
var baseURL = loc.protocol + "//" + loc.hostname;
if (typeof loc.port !== "undefined" && loc.port !== "") baseURL += ":" + loc.port;
// strip leading /
var pathname = loc.pathname;
if (pathname.length > 0 && pathname.substr(0,1) === "/") pathname = pathname.substr(1, pathname.length - 1);
var pathParts = pathname.split("/");
if (pathParts.length > 0) {
for (var i = 0; i < pathParts.length; i++) {
if (pathParts[i] !== "") baseURL += "/" + pathParts[i];
}
}
return baseURL;
}
Getting the base url |Calls controller from js
function getURL() {
var windowurl = window.location.href;
var baseUrl = windowurl.split('://')[1].split('/')[0]; //split function
var xhr = new XMLHttpRequest();
var url='http://'+baseUrl+'/url from controller';
xhr.open("GET", url);
xhr.send(); //object use to send
xhr.onreadystatechange=function() {
if(xhr.readyState==4 && this.status==200){
//console.log(xhr.responseText); //the response of the request
document.getElementById("id from where you called the function").innerHTML = xhr.responseText;
}
}
}
一个更简单的答案在这里, window.location.href = window.location.origin;
Split and join the URL:
const s = 'http://free-proxy.cz/en/abc'
console.log(s.split('/').slice(0,3).join('/'))
Put this in your header, so it will be available whenever you need it.
var base_url = "<?php echo base_url();?>";
You will get http://localhost:81/your-path-file
or http://localhost/your-path-file
