我有一段代码，它显示文件名列表。单击每个文件名会在右侧显示其正文。我们可以将文件添加到列表中。

点击每个文件名后，我的浏览器地址栏中的 url 会系统更新。有谁知道是否可以不更新网址栏，但仍能满足我的要求（即显示正文）？

是的，你可以这么做。您在 URL 中使用了 {name}。这就是为什么它每次都更改文件名的原因。将文件名作为 $stateParams 中的参数传递，并从 URL 中删除名称参数。

$stateProvider
        .state('file', {
            url: '/file',
            template: "{{file.body}}",
            controller: 'FileCtrl',
            params: {name: null}
        });
