js关于监听浏览器后退事件详解

<script>
 $(document).ready(function (e) {
 var counter = 0;
 if (window.history && window.history.pushState) {
 $(window).on('popstate', function () {
 window.history.pushState('forward', null, '#');
 window.history.forward(1);
 // alert("不可回退"); //如果需在弹框就有它
 self.location="orderinfo.html"; //如查需要跳转页面就用它
 });
 }

 window.history.pushState('forward', null, '#'); //在IE中必须得有这两行
 window.history.forward(1);
 });
</script>
