NativeScript初学者,我一直在网上搜索,但由于过去几个月在基本代码中似乎有很多迭代/更改,我在网上找到的例子非常不一致。
所以这里,我试图从“nativescript-telerik-ui / sidedrawer”实现一个简单的SideDrawer但是失败了。
需要注意以下几点:
以下是我的文件+代码:
的package.json
{
"nativescript": {
"id": "org.nativescript.githubreader",
"tns-ios": {
"version": "1.7.0"
},
"tns-android": {
"version": "1.7.1"
}
},
"dependencies": {
"github-api": "^0.11.2",
"lodash": "^4.10.0",
"nativescript-telerik-ui": "^1.0.1",
"tns-core-modules": "1.7.1"
},
"devDependencies": {
"nativescript-dev-typescript": "^0.3.0",
"typescript": "^1.8.9"
}
}
主要-page.xml
<Page xmlns="http://schemas.nativescript.org/tns.xsd"
xmlns:drawer="nativescript-telerik-ui/sidedrawer"
loaded="loaded"
navigatingTo="navigatingTo">
<drawer:rad-side-drawer id="sideDrawer">
<drawer:rad-side-drawer.mainContent>
<!-- Home page contents -->
<stack-layout>
<image src="https://i.imgur.com/LY3cb3A.png" id="logo" tap="" height="100" margin="20 0 0 0" />
<label text="Welcome to the NativeScript drawer template! This is the home page. Try tapping the logo." margin="20" horizontalAlignment="center" textWrap="true" />
</stack-layout>
</drawer:rad-side-drawer.mainContent>
<drawer:rad-side-drawer.drawerContent>
<widgets:drawer-content />
</drawer:rad-side-drawer.drawerContent>
</drawer:rad-side-drawer>
<StackLayout orientation="vertical">
<Label text="{{ message }}" class="message" textWrap="true"/>
</StackLayout>
</Page>
主要-page.ts
import { EventData } from "data/observable";
import { Page } from "ui/page";
import { MainModel } from "../../models/main-view";
let drawer:any;
// Event handler for Page "navigatingTo" event attached in main-page.xml
export function navigatingTo(args: EventData) {
// Get the event sender
const page = <Page>args.object;
page.bindingContext = new MainModel();
drawer = page.getViewById("sideDrawer");
console.log("navigatingTo");
console.log(drawer);
}
export function loaded(args: EventData) {
const page = <Page>args.object;
drawer = page.getViewById("sideDrawer");
console.log("Loaded");
console.log(drawer);
};
export function toggleDrawer() {
if(drawer) {
drawer.toggleDrawerState();
}
}
我真的被困在那里,真的很感谢一些有经验的人对此事的帮助。
NativeScript看起来很棒,真的很期待能够用它来构建一些好东西。
期待阅读一些答案,感谢您迄今为止的阅读:)
答案 0 :(得分:2)
1。)对于您的模块'ui / drawer-content'未加载问题:
您正在使用小部件:drawer-content 标记,而不对此小部件有任何引用。 您可以创建自定义小部件,而不是加载外部小部件。 例如,用以下代码替换未引用的小部件:
<StackLayout cssClass="drawerContent">
<StackLayout>
<Label text="Navigation Menu"/>
</StackLayout>
<StackLayout cssClass="drawerMenuContent">
<Label text="Primary" />
<Label text="Social" />
<Label text="Promotions" />
<Label text="Labels" />
</StackLayout>
</StackLayout>
2。)至于抽屉id未定义的问题,你应该在main-page.xml中删除代码的以下部分
<StackLayout orientation="vertical">
<Label text="{{ message }}" class="message" textWrap="true"/>
</StackLayout>
在抽屉:RadSideDrawer.mainContent 中实现您的初始页面内容(就像您已经完成的那样)。 原因是:sidedrawer不能与xml-tree中的其他ui元素处于同一级别。
<drawer:RadSideDrawer.mainContent>
<!-- Home page contents -->
<StackLayout>
<Image src="https://i.imgur.com/LY3cb3A.png" id="logo" />
<Label text="Welcome to the NativeScript drawer template! Swipe to show drawer!" margin="20" />
</StackLayout>
</ drawer:RadSideDrawer.mainContent>
