 1 | # VueTagTextarea
 2 | 
 3 | > 可插入自定义标签的 textarea
 4 | 
 5 | ## 安装
 6 | 
 7 | ``` bash
 8 | $ npm install vue-tag-textarea -S
 9 | ```
10 | ## 使用
11 | 
12 | 在 `main.js` 文件中引入插件并注册
13 | 
14 | ``` bash
15 | # main.js
16 | import VueTagTextarea from 'vue-tag-textarea'
17 | import 'vue-tag-textarea/lib/vue-tag-textarea.css'
18 | Vue.use(VueTagTextarea)
19 | ```
20 | 
21 | 在项目中用使用 VueTagTextarea
22 | 
23 | 
24 | ```js
25 | <template>
26 |   <w-textarea v-model="text" />
27 | </template>
28 | <script>
29 |   export default {
30 |     data () {
31 |       return {
32 |         text: 'demo'
33 |       }
34 |     }
35 |   }
36 | </script>
37 | ```
38 | 
39 | 注意：标签为 `<w-textarea>`
40 | 
41 | ## 特点
42 | 1. 可以插入自定义的标签，默认为 `<wise>`
43 | 2. 基于自定义标签，可以满足模版文案的需求
44 | 
45 | ## 参数
46 | 
47 | | 参数 | 说明 | 类型 | 默认值 |
48 | | ------ | ------ | ------ | ------ |
49 | | tag | 自定义标签名 | String | wise |
50 | | tools | 配置工具栏 | Array | [{ type: 'link', text: '添加超链接' }, { type: 'tag', text: '添加模版标签' }] |
51 | | maxlength | 最大字符长度 | String, Number | - |
52 | 
53 | > 自定义 tag 的时候，需要添加该标签的样式
54 | 
55 | 
56 | ## 事件
57 | 
58 | | 事件名称 | 说明 | 回调参数 |
59 | | ------ | ------ | ------ |
60 | | add | 点击工具栏上的“添加xx”按钮时触发 | type |
61 | 
62 | ## Add 事件详解
63 | 工具栏可以通过 tools 参数进行配置，tools 的元素是一个包含 type 和 text 的对象，其中 text 为工具栏按钮的文字。  
64 | 当点击工具栏按钮的时候，触发 add 事件，接收一个 type 参数，该参数为 tools 中定义的 type 属性值。  
65 | 具体的交互逻辑需要自行开发，最后需要通过 $refs 调用 VueTagTextarea 内部的 addLink() 或者 addTag() 方法，完成添加标签。  
66 | 当调用 addTag() 的时候，需要传入一个 text 参数，值为标签的文本内容。  
67 | 当调用 addLink() 的时候，需要传入 url 和 text，其中 url 为超链接地址，text 为超链接文本。  
68 | VueTagTextarea 最终返回的值是一个 innerHTML。
