JS gets each parameter of the URL.

JavaScript gets the two methods of the current URL parameter:

　　Returns a string as a parameter, such as:class_id=3&id=2&

function geturlargstr() {

var q=location. Search. Substr(1); 　　     

var qs=q. Split(' & '); 　　     

var argstr='; 　　    

if(qs) {

　　For(var i=0; I<Qs. Length; I+ +) {

 Argstr+=Qs[I].Substring (0,qs[ iindexof ( ' = ' ' = ' +qs[ isubstring (qs[iindexof ( ' = ' ) +< Span class= "lit" >1) + ' & ' ;  

        }     

　　}     

　　return argstr;

} 

Returns the parameter as an object form

function geturlargobject() {

var args=new Object();     

　　var query=location. Search. Substring(1); Get query string

< Span class= "pun" >< Span class= "pun" >      var pairs= query.//disconnects at comma

 For (var i=0; I<pairs. Length; I+ +) {         

　　　　var pos=pairs[i]. IndexOf(' = '); Find Name=value

< Span class= "pun" >< span class= "str" >       if (pos ==-1) {// Skip   if not found;             

continue; 　　　　         

　　}         

　　var argname=pairs[i]. Substring(0,pos); Extract name

var value=pairs[i]. Substring(pos+1); Extract value

args[argname]=unescape(value); Save As Property

　　}    

　　return args; Return object

}

Also list some JavaScript to get a functional approach to each part of the URL:

2. Window. Location.  Host; //Returns the host part of the URL, for example: www.xxx.com
4. Window. Location.  hostname; //Return to www.xxx.com
6. Window. Location.  href; //Returns the entire URL string (in the browser is the full address bar), for example : www.xxx.com/index.php?class_id=3&id=2
8. Window. Location.  Pathname; //Return to/a/index.php or /index.php
10. Window. Location.  Protocol; //Returns the protocol part of the URL, for example: Http:,ftp:,maito: And so on.  
12. Window. Location. the port portion of Ports//url, if the default 80 port is used, then the return value is not the default of 80 but the null character

JS gets each parameter of the URL.
