window.onbeforeunload=函数(evt){
console.log(“*******************”);
} 
现在假设点击索引按钮,我进入example.html页面。单击example.html中的“后退”按钮,它将再次转到index.html。一切正常,但它不打印console.log(“*********”;如果我在index.html上再按一次返回键,它就会打印出来,我想要的是当我在example.html上点击返回按钮时,它就会打印出来


上面的代码有什么问题?为什么会这样?如果您有任何建议,我们将不胜感激。

您所能做的就是在“后退”按钮中添加一个事件

如果您有一个按钮:

<button id="backButton"> Go Back </button>
请记住,如果您单击一个按钮,将出现一篇文章,页面将刷新。因此,您应该在另一页的documentready中添加log函数

因此,如果加载example.html页面,您只需触发此事件

$(function(){
   //All code that starts when the page is fully loaded.
    console.log ("*****************");
});

在jquerymobile标准使用中,您在站点上的孔体验基本上停留在同一页面上。“更改”页面基本上会将内容动态添加到当前文档中,这意味着它不会触发您的
onbeforeunload
事件。 但是,您可以使用,具体使用哪一种取决于您想要采取什么样的行动。很可能您会看到
pagebeforehide
pagehide

$(function(){
   //All code that starts when the page is fully loaded.
    console.log ("*****************");
});
