富文本编辑器Quill(一)简单介绍

Quill是一个很流行的富文本编辑器,github上star大约21k:

github:https://github.com/quilljs/quill/

官网: https://quilljs.com/

使用

<!-- Include stylesheet -->
<link href="https://cdn.quilljs.com/1.3.6/quill.snow.css" rel="stylesheet">

<!-- Create the editor container -->
<div id="editor">
  <p>Hello World!</p>
  <p>Some initial <strong>bold</strong> text</p>
  <p><br></p>
</div>

<!-- Include the Quill library -->
<script src="https://cdn.quilljs.com/1.3.6/quill.js"></script>

<!-- Initialize Quill editor -->
<script>
  var quill = new Quill('#editor', {
    theme: 'snow'
  });
</script>

下载:

npm install quill@1.3.6

vue中使用:

<template>
  <div>
    <div id="editor">
      <p>Hello World!</p>
      <p>Some initial <strong>bold</strong> text</p>
      <p><br></p>
    </div>
  </div>
</template>

<script>
import Quill from 'quill'

export default {
  name: "QuillEditor",
  mounted () {
    this.initQuill()
  },
  beforeDestroy () {
    this.quill = null
    delete this.quill
  },
  methods: {
    initQuill () {
      const quill = new Quill('#editor', {
        theme: 'snow'
      })
      this.quill = quill
    },
  }
}
</script>

效果

 

创建Quill实例需要两个参数,container与options

Container

container可以是css选择器,也可以是DOM对象:

const editor = new Quill('#editor')

或者

const container = document.getElementById('editor');
const editor = new Quill(container);

Options

包括theme、formats、modules等

const options = {
  debug: 'info',
  modules: {
    toolbar: '#toolbar'
  },
  placeholder: 'Compose an epic...',
  readOnly: true,
  theme: 'snow'
};
const editor = new Quill('#editor', options);

获取与显示编辑内容

富文本编辑器的主要作用是编辑文本、保存、显示等。

获取编辑完成的内容:

const html = document.querySelector('#editor').children[0].innerHTML
console.log(html)

内容:

<p>Hello World!</p><p>Some initial <strong>bold</strong> text</p><p><br></p>

获取内容后置于编辑器中显示:

const html = document.querySelector('#editor').children[0].innerHTML
this.quill.pasteHTML('<h3>add some title</h3>' + html)

显示:

Toolbar

编辑器上方一栏可以设置文本格式部分,即为modules中的toolbar,可以使用默认值,也可以定制。

使用数组:

const toolbarOptions = ['bold', 'italic', 'underline', 'strike'];

const quill = new Quill('#editor', {
  modules: {
    toolbar: toolbarOptions
  }
});

效果:

也可以分组:

const toolbarOptions = [
  ['bold', 'italic', 'underline', 'strike'],        // toggled buttons
  ['blockquote', 'code-block'],

  [{ 'header': 1 }, { 'header': 2 }],               // custom button values
  [{ 'list': 'ordered'}, { 'list': 'bullet' }],
  [{ 'script': 'sub'}, { 'script': 'super' }],      // superscript/subscript
  [{ 'indent': '-1'}, { 'indent': '+1' }],          // outdent/indent
  [{ 'direction': 'rtl' }],                         // text direction

  [{ 'size': ['small', false, 'large', 'huge'] }],  // custom dropdown
  [{ 'header': [1, 2, 3, 4, 5, 6, false] }],

  [{ 'color': [] }, { 'background': [] }],          // dropdown with defaults from theme
  [{ 'font': [] }],
  [{ 'align': [] }],

  ['clean']                                         // remove formatting button
];

const quill = new Quill('#editor', {
  modules: {
    toolbar: toolbarOptions
  },
  theme: 'snow'
});

效果

同一组会置于同一<span>中。

也可以使用css选择器,最全的toolbar

<div id="toolbar">
    <span class="ql-formats">
      <select class="ql-font"></select>
      <select class="ql-size"></select>
    </span>
    <span class="ql-formats">
      <button class="ql-bold"></button>
      <button class="ql-italic"></button>
      <button class="ql-underline"></button>
      <button class="ql-strike"></button>
    </span>
    <span class="ql-formats">
      <select class="ql-color"></select>
      <select class="ql-background"></select>
    </span>
    <span class="ql-formats">
      <button class="ql-script" value="sub"></button>
      <button class="ql-script" value="super"></button>
    </span>
    <span class="ql-formats">
      <button class="ql-header" value="1"></button>
      <button class="ql-header" value="2"></button>
      <button class="ql-blockquote"></button>
      <button class="ql-code-block"></button>
    </span>
    <span class="ql-formats">
      <button class="ql-list" value="ordered"></button>
      <button class="ql-list" value="bullet"></button>
      <button class="ql-indent" value="-1"></button>
      <button class="ql-indent" value="+1"></button>
    </span>
    <span class="ql-formats">
      <button class="ql-direction" value="rtl"></button>
      <select class="ql-align"></select>
    </span>
    <span class="ql-formats">
      <button class="ql-link"></button>
      <button class="ql-image"></button>
      <button class="ql-video"></button>
      <button class="ql-formula"></button>
    </span>
    <span class="ql-formats">
      <button class="ql-clean"></button>
    </span>
  </div>

  

<script>
  const quill = new Quill('#editor', {
    modules: {
      toolbar: '#toolbar'
    }
  });
</script>

  效果:

toolbar里的control与Quill的format是对应的,可以用来添加或者移除format:

formats

我们可以添加定制的handler来改变默认行为:

const toolbarOptions = {
  handlers: {
    // handlers object will be merged with default handlers object
    'link': function(value) {
      if (value) {
        var href = prompt('Enter the URL');
        this.quill.format('link', href);
      } else {
        this.quill.format('link', false);
      }
    }
  }
}

const quill = new Quill('#editor', {
  modules: {
    toolbar: toolbarOptions
  }
});

// Handlers can also be added post initialization
const toolbar = quill.getModule('toolbar');
toolbar.addHandler('image', showImageUI);

可以定制handler来进行图片视频上传。
