};
window.history.pushState(state, “title”, “#”);
}
});方法二：
if(window.history && window.history.pushState) {
$(window).on('popstate', function() {
var hashLocation = location.hash;
var hashSplit = hashLocation.split("#!/");
var hashName = hashSplit[1];
if(hashName !== '') {
var hash = window.location.hash;
if(hash === '') {
alert("你点击了返回键");
}
}
});
window.history.pushState('forward', null, './#forward');
