菱形背部功能

我在 Rhomobile 中使用后退按钮功能时遇到问题。

我尝试过 url_for(:index, :back => ....) 等各种方法，但似乎没有任何效果。这种方法的问题是（即使它有效）它只允许导航到设定的位置，而不是动态历史记录/返回导航。

我最接近的工作解决方案是在 application_helper: 中使用它

def page_back
    WebView.navigate_back
end

，然后在视图中使用 Back 。

这是可行的，我可以跨视图甚至控制器进行导航。但是，它会生成“加载页面时出错”错误，即使它确实呈现了正确的页面......

有人有任何想法吗？

I'm having a problem getting the back button function to work in Rhomobile.

I've tried various methods of url_for(:index, :back => ....) etc etc and nothing seems to work. The problem with this method is (even if it worked) that it only allows navigation to a set place, rather than a dynamic history/back navigation.

The closest I've come to a working solution is by using this in the application_helper:

def page_back
    WebView.navigate_back
end

and then <a href="page_back">Back</a> in the view.

This works, and i can navigate across views and even controllers. However, it generates a "Error loading page" error, even though it does actually render the right page...

Does anybody have any ideas?

好吧，这就是我最终所做的。我现在决定不使用 rhodes，但这是我针对此问题想到的：

将 data-add-back-btn="true" 添加到：

<div data-role="page" data-add-back-btn="true">

然后：

<div data-role="header" data-position="inline">
    <h1>Title</h1>
    <a href="page_back" class="ui-btn-left" data-theme="a" data-icon="arrow-l" data-rel="back" data-direction="reverse">Back</a>
</div>

Ok this is what I did in the end. I've decided against using rhodes now but here is what I came up with for this problem:

Added data-add-back-btn="true" to:

<div data-role="page" data-add-back-btn="true">

Then:

<div data-role="header" data-position="inline">
    <h1>Title</h1>
    <a href="page_back" class="ui-btn-left" data-theme="a" data-icon="arrow-l" data-rel="back" data-direction="reverse">Back</a>
</div>
