uni-app的editor的富文本编辑器

在官方文档中教程真是也太简单了，  
大家可以在官方代码中找到完整的内容  
https://github.com/dcloudio/hello-uniapp/blob/master/pages/component/editor/editor.vue  
记住editor中的内容需要全部在项目中都有才会显示出来样式，  
可以也修改一下简单的样式  
在然后值得说一下的上传图片和获取输入的内容，着两个在文档没有体现

在这里重点说明一下，因为没有好好看官方文档，只看了组件中的使用，没注意看api中关于富文本上写的，所以在小程序测试的时候报错，真真是气炸了，  
https://uniapp.dcloud.io/api/media/editor-context  
这个官方文档中写的

还有就是这个不能封装为组件用，封装为组件会报错

uni.createSelectorQuery().select('#editor').context((res) => {
    			console.log(res,'----------是空')
    	      this.editorCtx = res.context
    	    }).exec()

在每个使用到富文本编辑器组件的页面，配置 pages.json 文件如下：

{
        "pages": [ 
            {
                "path": "pages/index/index",
                "style": {
                    "navigationBarTitleText": "uni-app",
                    "usingSwanComponents": {
                        "editor": "dynamicLib://editorLib/editor"
                    }
                }
            }
        ]
    }

<view class="editor-wrapper">
    					<editor id="editor" class="ql-container" placeholder="开始输入..." showImgSize showImgToolbar showImgResize
    					 @statuschange="onStatusChange" :read-only="readOnly" @ready="onEditorReady" @input="getText">
    					</editor>
    				</view>
    				//获取内容
    			getText(e){//获取数据
    			    var that = this;
    				getApp().globalData.editor = e.detail.html
    			    // console.log(e.detail.html);//带标签内容
    			    // console.log(e.detail.text);//纯文本内容
    			},
    			//文件上传
    insertImage() {
    				var that = this;
    				uni.chooseImage({
    					count: 1,
    					success: (res) => {
    						console.log('insert image success')
    						const tempFilePaths = res.tempFilePaths;
    						uni.uploadFile({
    							url: url.uploadimageEider,
    							filePath: tempFilePaths[0],
    							name: 'image',
    							success: (uploadFileRes) => {
    								 let data=JSON.parse(uploadFileRes.data)
    								console.log(data,"编辑详情的时候返回照片地址")
    								var url=data.ip + data.data[0]
    								if(data.errno=="0"){
    									that.editorCtx.insertImage({
    										src: url,
    										alt: '图像',
    										success: function() {
    										}
    									})
    								}else{
    									that.showToast(back.msg)
    								}
    							},
    							fail:() =>{
    								uni.hideLoading();
    								that.showToast("图片上传失败，请联系开发！")
    							}
    						});
    					}
    				})
    			}

在官方文档中修改地方editor.vue完整文档
