Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@wines/backdrop

Backdrop 背景幕

在组件中设置显示蒙层。

使用指南

在 page.json 中引入组件

{
  "navigationBarTitleText": "Backdrop",
  "usingComponents": {
    "wux-button": "@wines/button",
    "wux-backdrop": "@wines/backdrop"
  }
}

示例

该组件主要依靠 JavaScript 主动调用,所以一般只需在 wxml 中添加一个组件,并设置 id 为 #wux-backdrop 或其他,之后在 page.js 中调用 $wuxBackdrop(context, id) 获取匹配到的第一个组件实例对象。

<wux-backdrop id="wux-backdrop" />

<view class="page">
	<view class="page__hd">
		<view class="page__title">Backdrop</view>
		<view class="page__desc">背景幕</view>
	</view>
	<view class="page__bd page__bd_spacing">
		<view class="btn-group">
			<wux-button block type="light" bind:click="retain">保持背景幕 retain</wux-button>
			<wux-button block type="light" bind:click="release">释放背景幕 release</wux-button>
		</view>
		<view class="text-center">背景幕锁:{{ locks }}</view>
	</view>
</view>
import './index.less';
import { $wuxBackdrop, BackdropExports } from '@wines/backdrop';

let wuxBackdrop: BackdropExports;
Page({
  data: {
    locks: 0,
  },
  onLoad() {
    wuxBackdrop = $wuxBackdrop();
  },
  retain() {
    wuxBackdrop.retain();
    this.setData({
      locks: wuxBackdrop.backdropHolds,
    });
  },
  release() {
    wuxBackdrop.release();
    this.setData({
      locks: wuxBackdrop.backdropHolds,
    });
  },
});
