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 🙏

introduction

让 iframe 父子通信更 easy

  • 不用被 parent、contentWindow 等概念困扰
  • 支持 Promise
  • 支持 Typescript

usage

import { setDefaultSon, setMsgHandler, sendSon, sendDad } from "iframe-msg";

向子 window 发送信息

向子 iframe 发送信息

// 简单发送
sendSon({ name: "wyf", sex: "male" }, "#id");

// 发送后监听响应
sendSon("hello", "#id").then((resp) => {
  console.log("对端响应信息:", resp);
});

向父 window 发送信息

// 简单发送
sendDad([1, 2, 3, 4]);

// 发送后监听响应
sendDad(666).then((res) => {
  console.log(res);
});

监听接受到的信息并回复

setMsgHandler((data, cb) => {
  console.log("父或子iframe发来了信息是:", data);
  cb("收到啦");
});

该监听不区分是来是 父级 还是 子级 的 frame,业务上可以自行区分

更多用法

sendSon 的第二个参数为需要发送的子 iframe,例如可能有多个 iframe,支持 3 中选择器

  • '#id'
  • '.class'
  • name

也可以直接传入 iframe 的 DOM 节点。

另外,可以设置默认子 iframe,这样就不必每次都写了子 iframe 了

setDefaultSon("#id");
sendSon("你好");
sendSon("我很开心");
