Jquery读取URL参数小例子

$(document).ready(function(){ 
function getQueryString(name) { 
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i"); 
var r = window.location.search.substr(1).match(reg); 
if (r != null) return unescape(r[2]); return null; 
} 
if (getQueryString("SignUp") == 1) 
{ 
$("#divLogon").css({ top: "auto", left: "auto", position: "absolute" }); 
$('#registerModal1').modal('show'); 
} 
})
