一个很不错的JS获取地址栏传值

function GetUrlParam( paramName )
{
    var oregex = new RegExp( '[\?&]' + paramName + '=([^&]+)', 'i' ) ;
    var oMatch = oregex.exec( window.top.location.search ) ;

    if ( oMatch && oMatch.length > 1 )
      return decodeURIComponent( oMatch[1] ) ;
    else
      return '' ;
}

var sConnUrl = GetUrlParam( 'Connector' ) ;

function getParam(name) {
        return location.href.match(new RegExp('[?#&]' + name + '=([^?#&]+)', 'i')) ? RegExp.$1 : '';
}
var centerParam = getParam('center');
