Working with URI in JavaScript

问题

I have a URL like below :

http://localhost:1692/fa/Help.aspx#Help

the code below returns that :

    alert(document.URL);

I only want to get the http://localhost:1692 part of this URL.

How can I get it with jQuery or JavaScript?

回答1:

Try this:

alert( location.protocol + "//" + location.host )

回答2:

location.protocol + '//' + location.host

And, if you want, you have these other properties:

• hash
• search - url querystring
• hostname - only the hostname (without port)
• port - only the port number
• pathname - the local url
