使用 jQuery 获取当前的 URL？

I am using jQuery. How do I get the path of the current URL and assign it to a variable?

Example URL:

http://localhost/menuname.de?foo=bar&number=0

To get the path, you can use:

var pathname = window.location.pathname; // Returns path only
var url      = window.location.href;     // Returns full URL
var origin   = window.location.origin;   // Returns base URL

You'll want to use JavaScript's built-in window.location object.

If you need the hash parameters present in the URL, window.location.href may be a better choice.

window.location.pathname
=> /search

window.location.href 
 => www.website.com/search#race_type=1

Just add this function in JavaScript, and it will return the absolute path of the current path.

function getAbsolutePath() {
    var loc = window.location;
    var pathName = loc.pathname.substring(0, loc.pathname.lastIndexOf('/') + 1);
    return loc.href.substring(0, loc.href.length - ((loc.pathname + loc.search + loc.hash).length - pathName.length));
}

I hope it works for you.

In pure jQuery style:

$(location).attr('href');

The location object also has other properties, like host, hash, protocol, and pathname.

For the host name only, use:

window.location.hostname

This is a more complicated issue than many may think. Several browsers support built-in JavaScript location objects and associated parameters/methods accessible through window.location or document.location. However, different flavors of Internet Explorer (6,7) don't support these methods in the same way, (window.location.href? window.location.replace() not supported) so you have to access them differently by writing conditional code all the time to hand-hold Internet Explorer.

So, if you have jQuery available and loaded, you might as well use jQuery (location), as the others mentioned because it resolves these issues. If however, you are doing-for an example-some client-side geolocation redirection via JavaScript (that is, using Google Maps API and location object methods), then you may not want to load the entire jQuery library and write your conditional code that checks every version of Internet Explorer/Firefox/etc.

Internet Explorer makes the front-end coding cat unhappy, but jQuery is a plate of milk.

This will also work:

var currentURL = window.location.href;

I have this to strip out the GET variables.

var loc = window.location;
var currentURL = loc.protocol + '//' + loc.host + loc.pathname;

 var currenturl = jQuery(location).attr('href');

You can log window.location and see all the options, for just the URL use:

window.location.origin

for the whole path use:

window.location.href

there's also location.__

.host
.hostname
.protocol
.pathname

This will return the absolute URL of the current page using JavaScript/jQuery.

• document.URL

• $("*").context.baseURI

• location.href

If there is someone who wants to concatenate the URL and hash tag, combine two functions:

var pathname = window.location.pathname + document.location.hash;

To get the URL of the parent window from within an iframe:

$(window.parent.location).attr('href');

NB: only works on same domain

window.location is an object in javascript. it returns following data

window.location.host          #returns host
window.location.hostname      #returns hostname
window.location.path          #return path
window.location.href          #returns full current url
window.location.port          #returns the port
window.location.protocol      #returns the protocol

in jquery you can use

$(location).attr('host');        #returns host
$(location).attr('hostname');    #returns hostname
$(location).attr('path');        #returns path
$(location).attr('href');        #returns href
$(location).attr('port');        #returns port
$(location).attr('protocol');    #returns protocol

// get current URL

$(location).attr('href');
var pathname = window.location.pathname;
alert(window.location);

java-script provides many methods to retrieve current URL which is displayed in browser's address bar.

URL

Authentication url with username:password, If usernaem/password contains @ symbol
like:

Username = `my_email@gmail`
password = `Yash@777`

then You need to URL encode the @ as %40. ^Refer...

http://my_email%40gmail.com:Yash%40777@www.my_site.com

var newURL = window.location.protocol + "//" + window.location.host + "/" + window.location.pathname;

You can simply get your path using js itself, window.location or location will give you the object of current URL

console.log("Origin - ",location.origin);
console.log("Entire URL - ",location.href);
console.log("Path Beyond URL - ",location.pathname);
