我正在使用jQuery Mobile，在用户单击主页上的按钮后，我想将浏览器重定向到另一个页面。 为此，我写道：

$.mobile.changePage("album-search-results.html",{
               data:{area:searchArea, value:searchValue},
               transition: "pop"
           });
它工作正常，加载正确的页面，甚至在URL上输入正确的值。很遗憾，pageshow事件未触发：

$（“#搜索结果”）。在（“页面显示”，函数（事件，用户界面）{
console.log（ui.prevPage）；
});
当我从上一页加载此页时，中的控制台始终为空。怎么了？ 谢谢

解决方案 解决方案很简单，将脚本块移动到页面div中。在这种情况下，脚本块将被丢弃。基本上是这样改变的：

我以为pageshow只是目标文档的一个事件？我以为pageshow只是目标文档的活动？
