关于uniapp:uniapp开发app使用wangeditor富文本编辑器进行编辑查看

wangeditor 是后盾比拟罕用的一个富文本编辑器，官网链接：https://www.wangeditor.com/

留神：
兼容支流的 PC 浏览器，如 Chrome Firefox Safari Edge 等。
暂不反对挪动端编辑（反对挪动端查看）。
不再反对 IE 浏览器。

我的需要，可能在挪动端编辑、查看，并且可能联动后盾。
我在网上找了很多挪动端的富文本编辑器，都不合乎我的需要，最初应用了 webview 的形式去实现 wagneditor4 版本。

具体实现代码如下：
index.vue 文件代码

<template>
    <view class="initiateContract">
        <div class="headerTip" :style="'margin-top:' + height + 'px;'">
            <div class="title">
                <div class="txt">{{contractDetails.title}}</div>
                <div class="status">
                    <u-tag v-if="contractDetails.flow_status ==='1'":text="contractDetails.flow_status_name"type="info"size="mini" plain></u-tag>
                    <u-tag v-if="contractDetails.flow_status ==='2'":text="contractDetails.flow_status_name"type="warning"size="mini" plain></u-tag>
                    <u-tag v-if="contractDetails.flow_status ==='3'":text="contractDetails.flow_status_name"type="warning"size="mini" plain></u-tag>
                    <u-tag v-if="contractDetails.flow_status ==='5'":text="contractDetails.flow_status_name"type="success"size="mini" plain></u-tag>
                </div>
            </div>
            <div class="info"> 留神：合同签订区的代码英文，如 company_sign、demand_sign、aunt_sign 等英文代码请勿删除 </div>
        </div>

创立富文本编辑器用法：

<!-- 工具栏 -->
<div id="toolbar-container" class="toolbar" style="display: none;"></div>
<!-- 编辑器 -->
<div id="text-container" class="text"></div>

<script>
    // 创立富文本编辑器
    const E = window.wangEditor
    const editor = new E('#toolbar-container', '#text-container')
    // 如果不想显示工具栏，能够将款式设置为 display: none;

    editor.create()        // 创立
    
    editor.disable()    // 禁止编辑
    editor.txt.html()    // 获取文本内容
</script>
