Method to get address bar parameters using JavaScript

/**

 *   Gets the address bar parameter 

 *

 * @example GetUrlString('id')

 *

 * @desc     Add judgment to the call to ensure that the program does not fail 

 *             var myurl = GetUrlString('id');

 *             if (myurl != null && myurl.toString().length > 1) {

 *                  alert(GetUrlString("id"));  

 *             }

 *

 * @param String  param  To get the parameter name in the address bar 

 * @return String Value

 * @type String

 *

 * @name GetUrlString()

 *

 */

function GetUrlString(param) {

    var sValue = location.search.match(new RegExp("[\?\&]" + m + "=([^\&]*)(\&?)", "i"));

    return sValue ? decodeURI(sValue[1]) : decodeURI(sValue);

}

Call when 1 to make such a judgment, to avoid you do not pass parameters, such as your address is abc

window.onload = function() {    

    var myurl = GetParm("id");

    if (myurl != null && myurl.toString().length > 1) {

        alert(GetParm("id"));

    }

}

So you don't report an error!

Note: ECMAScript v3 has removed the unescape() function from the standard and objects to its use, so decodeURI() and decodeURIComponent() should be used instead.
