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 🙏

跨域 iframe父子页面之间通信

实现了父子页面之间类似 request / response 的通信方式。

例子一

iframe 子页面请求从父业面中获取用户信息



/**
 * iframe 子页面。请求从父业面中获取用户信息
 * @returns {Promise<void>}
 */
async function demo_sender() {
    let userInfo = await corsMsg.sendCorsScript({
        scriptName:'GET_USER_INFO'
    });

    console.log(userInfo)
}


/**
 * iframe 父页面. 响应子页面的请求返回数据
 * @returns {Promise<void>}
 */

corsMsg.acceptCorsScript('GET_USER_INFO', async function () {
        //如果是异步结果,返回Promise对象。
        return {username:'zhangsan',age:3223}
})


例子二

iframe 子页面直接在父业面中执行脚本


/**
 * iframe 子页面。直接在父业面中执行脚本
 * @returns {Promise<void>}
 */
async function demo2_sender() {
    await corsMsg.sendCorsScript({
        scriptName:'SET_USER_INFO',
        scriptString:`window.currentUserInfo=${JSON.stringify({username:'李四',age:18})}` //这段代码实际上在父业面执行
    });
}


/**
 * iframe 父页面. 允许子页面执行SET_USER_INFO脚本
 * @returns {Promise<void>}
 */
corsMsg.acceptCorsScript('SET_USER_INFO');
