Polymer Iron Flex Mixin 不起作用,但 类 起作用
Polymer Iron Flex Mixin's Don't Work, But Classes Do
我使用 类 让 Polymer iron-flex-layout 在我的 AngularDart 组件中工作。由于它会生成弃用警告,我认为会尝试推荐的替代方案:mixin's。它们不起作用。
目前,我的 artist_component.dart 中有这个导入:
import 'package:polymer_elements/iron_flex_layout.dart';
我也试过将这个添加到我的 index.html
<link rel="import" href="packages/polymer_elements/iron_flex_layout.html">
这与使用 bower 的文档中给出的示例不同。在我的 artist_component.html 中,我有:
<style is="custom-style">
.container {
@apply(--layout-horizontal);
}
.flexchild {
@apply(--layout-flex-3);
}
.flexchild-2 {
@apply(--layout-flex-9);
}
</style>
<section class="container">
<section class="flexchild gutter">
...
我已经尝试将导入内容与样式一起放入 index.html 和我的主 css 文件中,但没有任何影响。考虑到 类 工作你会认为 mixim 也可以。
我一直在挖掘,我找到了答案。我还发现该方法已被弃用。我的 pubspec 定义了这些版本:
polymer: ^1.0.0-rc.17
polymer_elements: ^1.0.0-rc.8
我很确定解决方案是将这行代码添加到我的 index.html:
<link rel="import" href="packages/polymer/polymer.html">
我不肯定这是唯一的要求的原因是我一直在改变很多东西来让它工作。这是我完整的 index.html:
<!DOCTYPE html>
<html>
<head>
<title>Jazz Cat</title>
<script>
window.Polymer = window.Polymer || {};
window.Polymer.dom = 'shadow';
</script>
<!-- For testing using pub serve directly use: -->
<base href="/">
<!-- For testing in WebStorm use: -->
<!-- <base href="/dart/web/"> -->
<link rel="import" href="packages/polymer/polymer.html">
<link rel="import" href="packages/polymer_elements/iron_flex_layout.html">
<link href="master.css" rel="stylesheet" type="text/css" />
<style is="custom-style">
.container {
@apply(--layout-horizontal);
}
.element-index {
@apply(--layout-flex-3);
}
.element-body {
@apply(--layout-flex-9);
}
.element-main {
@apply(--layout-flex-7);
}
.element-sidebar {
@apply(--layout-flex-2);
}
</style>
<script defer src="main.dart" type="application/dart"></script>
<script defer src="packages/browser/dart.js"></script>
</head>
<my-app>Loading...</my-app>
</html>
现在我开始工作了,我会将我的样式移动到一个单独的文件中。这是我使用 mixin 类:
的文件之一
<section class="container">
<section class="element-index">
<h1>{{title}}</h1>
<paper-listbox class="scroll-list" (click)="onScroll()">
<paper-item class="item-height" *ngFor="let artist of artists" [class.selected]="artist == selectedArtist" (click)="onSelect(artist)">
{{artist.first_name}} {{artist.last_name}}

根据 的回答,为 polymer 1.1 创建了一种新方法,该方法已被弃用。
