Jquery获取URL参数值

function Request(paras) {

var url = location.href;

var paraString = url.substring(url.indexOf("?") + 1, url.length).split("&");

var paraObj = {}

for (i = 0; j = paraString[i]; i++) {

paraObj[j.substring(0, j.indexOf("=")).toLowerCase()] = j.substring(j.indexOf("=") + 1, j.length);

}

var returnValue = paraObj[paras.toLowerCase()];

if (typeof (returnValue) == "undefined") {

return "";

} else {

return returnValue;

}

}
