Query the string parameters contained in the url (js elevation notes) and js elevation.

Function getArgs () {var args ={}; // create the object var qs = location. search. length> 0? Location. search. substring (1): ''; // obtain the query string and remove the question mark (var items) = qs. split ('&'); // split the array by & string var item = null, name = null, value = null; // Add each item to The args object one by one for (var I = 0; I <items. length; I ++) {item = items [I]. split ('='); name = item [0]; value = item [1] args [name] = value;} return args;} var args = getArgs (); alert (args ['id']); alert (args ['search']);
