Javascript-js tutorial

A very good Javascript operation URL function can be added, modified, and deleted. Some methods are summarized to compress it into a function object. There are only dozens of lines of code. The method is simple and clear.
Save as ojbUrl. js

The Code is as follows:

Instructions for using js url functions:
Initialize var myurl = new objURL (); // You can also customize the URL: var myurl = new objURL ('HTTP: // www.jb51.net ');
Read the url parameter value var val = myurl. get ('abc'); // read the value of the parameter abc
Set the url parameter myurl. set ("arg", data); // Add/modify the value of an arg parameter to data
Remove the url parameter myurl. remove ("arg"); // remove the arg Parameter
Obtain the processed URL myurl. url (); // you can directly jump to location. href = myurl. url ();
Debug interface: myurl. debug (); // modify the function for debugging
*/
Function objURL (url ){
Var ourl = url | window. location. href;
Var href = "";//? Previous section
Var params ={}; // url parameter object
Var jing = ""; // # and subsequent sections
Var init = function (){
Var str = ourl;
Var index = str. indexOf ("#");
If (index> 0 ){
Jing = str. substr (index );
Str = str. substring (0, index );
}
Index = str. indexOf ("? ");
If (index> 0 ){
Href = str. substring (0, index );
Str = str. substr (index + 1 );
Var parts = str. split ("&");
For (var I = 0; I Var kv = parts [I]. split ("= ");

Call Method
Instructions for using js url functions:
[Code]
Var myurl = new objURL (); // initialization. You can also customize the URL: var myurl = new objURL ('HTTP: // www.jb51.net '');
Var val = myurl. get ('abc'); // read the value of parameter abc
Myurl. set ("arg", data); // Add/modify the value of an arg parameter as data
Myurl. remove ("arg"); // remove the arg Parameter
Myurl. url (); // obtain the processed URL. Generally, the jump is directly executed: location. href = myurl. url ();
Myurl. debug (); // This is the debugging interface. Modify the Function Method for debugging
