JavaScript無刷新修改url： ``` var keyword = '11'; var originUrl=window.location.href; var valiable = originUrl.split("?")[0]; window.history.pushState(null, null, valiable+"?keyword="+keyword+""); ``` JavaScript重定向跳转到指定参数值： ``` varoriginUrl\=window.location.href; varvaliable = originUrl.split("?")\[0\];  window.location.href = valiable+"?keyword=""; ```
