js获取链接地址参数

function getParameter(name) {
    var query = window.location.search;
    var iLen = name.length;
    var iStart = query.indexOf(name);
    if(iStart == -1)
        return "";
    iStart += iLen + 1;
    var iEnd = query.indexOf("&", iStart);
    if(iEnd == -1)
        return query.substring(iStart);
}
           

直接上代码了！
