Question

大家好，我是 KivyMD 的新手，正在开发我的第一个应用程序。基本上，我需要在单击导航抽屉中的内容时打开一个新屏幕。例如，我的导航抽屉上有一个“新建房间”按钮，我希望在单击它时打开一个新屏幕。

好的，这是我的代码

$testData = [
    '<a href=""><img/></a>',
    '<a href="#"><img/></a>',
    '<a class="button" href="#" rel="nofollow"><img/></a>',
    '<a href=""><img/></a>',
];

foreach ($testData as $test) {
    $d = new DOMDocument();
    $d->loadHTML($test, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
    foreach ($d->getElementsByTagName('a') as $tag) {
        if (in_array(trim($tag->getAttribute('href')), ['#', ''], true)) {
            $tag->setAttribute('href', 'https://example.com');
        }
    }
    echo $d->saveHTML(), PHP_EOL;
}

这是我的字符串

from kivymd.app import MDApp
from kivy.lang import Builder
from kivy.uix.screenmanager import Screen, ScreenManager
from home_page_strings import toolbar


class EMC_WebmaApp(MDApp):
    def build(self):
        screen = Screen()

        # theme settings
        self.theme_cls.primary_palette = 'DeepPurple'
        self.theme_cls.theme_style = 'Dark'
        # end of theme declaration

        # loaded strings
        navigation_bar = Builder.load_string(toolbar)
        # end of loaded strings

        # addition of loaded strings to screen + return screen
        screen.add_widget(navigation_bar)

        return screen
        # end of addition


EMC_WebmaApp().run()

感谢帮助???
