用js代码在页面上禁用浏览器的后退按钮

这里使用了jquery, 先引入jquery

function disableBack() {
    if (window.history && window.history.pushState) {
        $(window).on('popstate', function () {
            window.history.pushState('forward', null, '');
            window.history.forward(1);
        });
    }
    window.history.pushState('forward', null, '');
    window.history.forward(1);
}
