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 🙏

描述

模拟复合组件的失去焦点

安装

npm i --save @kne/use-simulation-blur

概述

一个用来模拟失去焦点事件的钩子

为何需要使用?

在某些场景中,比如表单字段组件中,有两个输入框组合而成的复合字段,我们希望程序在用户完成两个文本框的输入时执行表单字段校验。 我们不能利用两个输入框任何一个的onBlur事件来触发校验,因为这样时不符合用户直觉和使用逻辑的。

这种情况,我们通过用户进入复合字段组件区域,完成输入,然后点击此区域外的地方来模拟触发onBlur事件来完成交互过程。

示例

示例样式

.container {
  display: inline-block;
  background: #cccccc;
  padding: 20px;
}

示例代码

  • 基本示例
  • 灰色区域为组件内部,在两个输入框输入完成后点击灰色区域外面触发失去焦点事件
  • _useSimulationBlur(@kne/use-simulation-blur),input(antd/lib/input),space(antd/lib/space),_message(antd/lib/message)
const { default: useSimulationBlur } = _useSimulationBlur;
const { default: Input } = input;
const { default: Space } = space;
const { default: message } = _message;

const BaseExample = () => {
  const ref = useSimulationBlur(() => {
    message.success('失去焦点');
  });
  return <div className='container' ref={ref}>
    <Space>
      <Input type='text' />
      <Input type='text' />
    </Space>
  </div>;
};

render(<BaseExample />);

API

const ref = useSimulationBlur(callback, options);

注意:返回的ref必须传给一个dom的ref

|属性名|说明|类型| 默认值 | | --- | --- | --- |--------------------| |callback|模拟的失去焦点事件触发后执行的回调|function| - | |options|{strictMode} strictMode为是否开启严格模式,如果开启严格模式,只有容器内部的组件触发focus事件才会开启监听,通常还会监听容器的点击事件|object| {strictMode:false} |
