lyy7319 edited a comment on issue #10937: 混合开发，在ios app嵌入带有echarts的页面，退出进入几次后图标消失，页面报错 URL: https://github.com/apache/incubator-echarts/issues/10937#issuecomment-516801067 > 监听退出页面的事件，调用 `chart.dispose()` 监听了 也dispose了 但是页面依然报错 ，使用如下方式监听，然后监听中销毁 ```js pushHistory(); window.addEventListener("popstate", function(e) { alert("我监听到了浏览器的返回按钮事件啦");//根据自己的需求实现自己的功能 }, false); function pushHistory() { var state = { title: "title", url: "#" }; window.history.pushState(state, "title", "#"); } ```
