JQuery禁用浏览器前进、后退按钮

$(document).ready(function () {
		if (window.history && window.history.pushState) {
			$(window).on('popstate', function () {
				// 当点击浏览器的 后退和前进按钮 时才会被触发，
				window.history.pushState('forward', null, '');
				window.history.forward(1);
			});
		}
		window.history.pushState('forward', null, '');  //在IE中必须得有这两行
		window.history.forward(1);
	});
