Question

我有一段代码，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，我的浏览器地址栏会系统地更新网址。有谁知道是否有可能不更新网址栏，但仍能实现我的要求（即显示正文）？

是的，你可以这样做。您在URL中使用了{name}。这就是它每次都在改变文件名的原因。将文件名作为$ stateParams中的参数传递，并从URL中删除name参数。

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

不要更新URL
