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

tethys

这是一个微型的库,包含最常用的dom操作,压缩后只有4KB

起源

自从 angularvue 这类框架出现之后,我们终于不用再面对业务逻辑dom操作混杂的代码。

但是,在极少的时候,特别是在组件中,我们仍然想要对页面元素进行直接的处理。

可是,你又不想仅仅为了用到几个方法,就去引入几十K的zepto或上百K的jquery

这种情况下,tethys是一个不错的选择。

它包含以下实例方法:

和以下静态方法:

安装

如果在Node.js环境中使用,通过以下命令安装它。

npm i tethys

https://www.npmjs.com/package/tethys

引用

标签引入:

<script src="https://raw.githubusercontent.com/hapjs/tethys/master/tethys.min.js"></script>

如果通过script方式引入,你可以通过全局变量tethys来调用它。

如果全局变量$没有被其它库或者变量占用的话,那么$会指向tethys

CommonJS/CMD/AMD引入:

var $ = require('tethys');

ES6引入:

import $ from 'tethys';

查找元素

通过选择器查找

$('#id');
$('.class');

直接传入元素

$(document.body);

指定查找范围

$('style', document.head);

与jQuery类似,你将得到一个包含查找到的节点的数组,这个数组有下列方法供你操作:

find

查找子元素

$('head').find('script'); // 查找<head>中的所有<script>

each

遍历

$('script').each(function(script, index){
    // console.log(this.getAttribute('type'));
});

on

事件绑定

$('button').on('click', function(){
    // this.style.color = 'red';
});

trigger

触发元素上绑定的事件监听函数

$('button').trigger('click');

可以触发的事件包括:

focus
blur
select
change

和所有鼠标事件:

mousedown
mouseup
mousemove
click
dblclick
mouseover
mouseout
mouseenter
mouseleave
contextmenu

css

查询实际样式(computedStyle)

$('button').css('color'); // red

设置样式

$('button').css('color', 'red');
$('button').css({
    display: 'block',
    border: '1px solid green'
});

style

查询内联样式,如果没有内联样式,返回空字符串

$('button').style('color');

width

设置或查询宽度,参数或返回值均不带单位且是数值类型

$('button').width();
$('button').width(200);

height

设置或查询高度,参数或返回值均不带单位且是数值类型

$('button').height();
$('button').height(200);

attr

设置单个属性

$('button').attr('maxlength', 16);

设置多个属性

$('button').attr({
    'maxlength': 16
});

取属性:

$('button').attr('maxlength'); // 16

class

添加class

$('button').addClass('active');

删除class

$('button').removeClass('active');

判断是否存在指定class

$('button').hasClass('active'); // true

show/hide

显示

$('button').show();

隐藏

$('button').hide();

html

修改文档的innerHTML

$('button').html('<p>Hello world!</p>');

append

追加子元素

$('button').append('<p>Hello world!</p>');

delay

延时执行一个函数

$('button').addClass('fade-out').delay(1000, function(){
    this.hide();
});

链式调用

$('button')
    .css('color', 'red')
    .addClass('active')
    .each(function(){ })
    .on('click', function(){ });

获得原生节点

栗子1:获得第一个script标签

$('script')[0]; // <script>...</script>

栗子2:遍历所有style标签

$('style').each(function(){
    // <style>...</style>
})

静态方法

除了上述实例方法以外,还有下面的静态方法可以使用。

extend

浅层复制

$.extend(obj1, obj2);

$.extend(obj1, obj2, obj3);

深层复制

$.extend(true, obj1, obj2)
