parse URL with JavaScript or jQuery

Question

Ok lets say I have a URL

example.com/hello/world/20111020 (with or without the trailing slash). What I would like to do is strip from the url the domain example.com.

Answer 1

This should work

var url = 'example.com/hello/world/20111020/';
//get rid of the trailing / before doing a simple split on /
var url_parts = url.replace(/\/\s*$/,'').split('/'); 
//since we do not need example.com
url_parts.shift(); 

Now url_parts will point to the array ["hello", "world", "20111020"].

Answer 2

   <script type="text/javascript">
    function splitThePath(incomingUrl){
     var url = document.createElement("a");
     url.href = incomingUrl;
    //url.hash  Returns the anchor portion of a URL
    //url.host  Returns the hostname and port of a URL
    //url.hostname  Returns the hostname of a URL
    //url.href  Returns the entire URL
    //url.pathname  Returns the path name of a URL
    //url.port  Returns the port number the server uses for a URL
    //url.protocol  Returns the protocol of a URL
    //url.search    Returns the query portion of a URL
    if(url.pathname && url.pathname != ""){
   var pathnameArray = url.pathname.split("/");
 }else{

}


}
</script>

Answer 3

I have created the following regular expression for URLs

^https?://(((0|([1-9][0-9]{0,1}))(\.(0|([1-9][0-9]{0,1}))){3})|([a-zA-Z]([a-zA-Z0-9$\-_@\.&+!*"\'\(\),]|(%[0-9a-fA-F][0-9a-fA-F]))*(\.([a-zA-Z]([a-zA-Z0-9$\-_@\.&+!*"\'\(\),]|(%[0-9a-fA-F][0-9a-fA-F]))*))*))(/|((/([a-zA-Z]([a-zA-Z0-9$\-_@\.&+!*"\'\(\),]|(%[0-9a-fA-F][0-9a-fA-F]))*))*))$

It has been written for MySql - I am sure with a bit of fiddling you can get it you work for your needs.

BTW - I took the idea from an RFC - The number escapes me at this moment

Answer 4

You can use the jQuery-URL-Parser plugin:

var file = $.url.attr("file"); 

In your case you'd probably want to use segment():

var segments = $.url('http://allmarkedup.com/folder/dir/example/index.html').segment(); 

// segments = ['folder','dir','example','index.html']

Answer 5

For parsing URLs, one different approach can be using anchor DOM object.

var a = document.createElement("A");
a.href = 'http://example.com:8080/path/to/resources?param1=val1&params2=val2#named-anchor';

a.protocol; // http:
a.host; // example.com:8080
a.hostname; //example.com
a.port; // 8080 (in case of port 80 empty string returns)
a.pathname; // /path/to/resources
a.hash; // #named-anchor
a.search // ?param1=val1&params2=val2
