js正则获取url参数,包含hash[#]和search[?]两种通用

function getQueryString(name) { 
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i"); 
var r = (window.location.hash || window.location.search).substr(1).match(reg); 
if (r != null) return unescape(r[2]); return null; 
}

  

调用:

getQueryString(参数)

  

更新:

const getUrlparam = (param) => {
    const reg = new RegExp('(^|&)' + param + '=([^&]*)(&|$)');
    const r = window.location.search.substr(1).match(reg) || window.location.hash.substring((window.location.hash.search(/\?/)) + 1).match(reg);
    if (r != null) {
        return decodeURIComponent(r[2]);
    }
};
