Js阻止瀏覽器頁面回退

$(document).ready( function(e) { var counter = 0; if (window.history && window.history.pushState) { $(window).on( 'popstate', function () { window.history.pushState( 'forward', null, '#'); //window.location.href="ad.html"; // 回退時跳轉到新頁面 window.history.forward( 1); alert( "不可回退"); }); } window.history.pushState( 'forward', null, '#'); //在IE中必須得有這兩行 window.history.forward( 1); });
