js修改浏览器地址栏里url的方法

1、更新url某一参数的值

function updateQueryStringParameter(uri, key, value) {if (!value) { return uri }var re = new RegExp("([?&])" + key + "=.*?(&|$)", "i");var separator = uri.indexOf('?') !== -1 ? "&" : "?";if (uri.match(re)) {return uri.replace(re, '$1' + key + "=" + value + '$2');}else {return uri + separator + key + "=" + value;}
}

2、删除url某一参数

function removeQueryStringParameter(uri, key) {var re = new RegExp("([&]?)" + key + "=.*?(&|$)", "i");var separator = uri.indexOf('?') !== -1 ? "&" : "?";if (uri.match(re)) {return uri.replace(re, '');}}

3、使用

let newurl = updateQueryStringParameter(window.location.href, 'projectId', '123');// 更新当前url，没有历史记录
window.history.replaceState({path: newurl
}, '', newurl);

let newurl = removeQueryStringParameter(window.location.href, 'projectId');// 更新当前url，没有历史记录
window.history.replaceState({path: newurl
}, '', newurl);
