微信小程序实现富文本编辑器

Rolan 2021-10-13 00:45

最近学习了微信小程序,于是乎,研究了一下评论功能。首先我们的环境是:微信小程序+thinkphp6上代码微信小程序 jwt 登录:https://blog.csdn.net/lh25946/article/details/119044247?spm=1001.2014.3001.5501表字段 ...

1.参考官方文档

  https://developers.weixin.qq.com/miniprogram/dev/component/editor.html

  在文档最下方有示例代码,如下图:

  点击“在开发者工具中预览效果”

2.将示例代码保存至桌面,以便后期操作

3.文件甲中有一下文件,如下图,我们主要使用前两个文件夹

4.将前两个文件甲复制到你项目的根目录下

5.写代码

  wxml代码:

复制代码
 1 <view class="container" style="height:{{editorHeight}}px;">
 2   <editor id="editor" class="ql-container" placeholder="{{placeholder}}" bindstatuschange="onStatusChange" bindready="onEditorReady">
 3   </editor>
 4 </view>
 5 
 6 <view class="toolbar" catchtouchend="format" hidden="{{keyboardHeight > 0 ? false : true}}" style="bottom: {{isIOS ? keyboardHeight : 0}}px">
 7   <i class="iconfont icon-charutupian" catchtouchend="insertImage"></i>
 8   <i class="iconfont icon-format-header-2 {{formats.header === 2 ? 'ql-active' : ''}}" data-name="header" data-value="{{2}}"></i>
 9   <i class="iconfont icon-format-header-3 {{formats.header === 3 ? 'ql-active' : ''}}" data-name="header" data-value="{{3}}"></i>
10   <i class="iconfont icon-zitijiacu {{formats.bold ? 'ql-active' : ''}}" data-name="bold"></i>
11   <i class="iconfont icon-zitixieti {{formats.italic ? 'ql-active' : ''}}" data-name="italic"></i>
12   <i class="iconfont icon-zitixiahuaxian {{formats.underline ? 'ql-active' : ''}}" data-name="underline"></i>
13   <i class="iconfont icon--checklist" data-name="list" data-value="check"></i>
14   <i class="iconfont icon-youxupailie {{formats.list === 'ordered' ? 'ql-active' : ''}}" data-name="list" data-value="ordered"></i>
15   <i class="iconfont icon-wuxupailie {{formats.list === 'bullet' ? 'ql-active' : ''}}" data-name="list" data-value="bullet"></i>
16 </view>

  wxss代码:(注:前两行的路径要自行修改)

复制代码

46   border: 1px solid #ECECEC;
47   border-left: none;
48   border-right: none;
49 }
复制代码


json代码:

1 {
2   "navigationBarTitleText": "发表文章",
3   "disableScroll": true
4 }

6.然后依次保存就好

7.最后点击真机调试,用手机扫描二维码便可以使用了。
