JS正则表达式将url转成json格式

var url=‘https://www.baidu.com/s?ie=utf-8&f=8&rsv_bp=1&rsv_idx=1&tn=baidu&wd=js%E6%AD%A3%E5%88%99%E8%A1%A8%E8%BE%BE%E5%BC%8F&oq=js%E6%AD%A3%E5%88%99%E8%A1%A8%E8%BE%BE%E5%BC%8F%20kongge&rsv_pq=e63baa94000c303c&rsv_t=2200EoMMe0fGnSJlPpijBDY2Ww1CAkUxvT8jCE2Bif1gXLJ%2Btzixfz%2BAtLE&rsv_enter=1&inputT=294&rsv_sug3=56&rsv_sug1=15&rsv_sug7=100&rsv_sug2=0&rsv_sug4=772&rsv_sug=2‘; //解析模拟地址栏
// var url = location.search.substr(1);  //这是截取地址栏的情况下，“？”问号以后的内容
var param = {};
url.replace(/([^?&]+)=([^?&]+)/g, function(s, v, k) {
    console.log(‘这个是选出a=b是：‘+s+‘，\n这个是键是：‘+v+‘，\n这个是值是：‘+k+‘。‘);
    param[v] = decodeURIComponent(k);//解析字符为中文
    return k + ‘=‘ +  v;
});
console.log(param);
