element-ui + el-dialog + Vue.component 注册的富文本控件 第二次及以后打开dialog出现问题解决方法

Vue.component('my-tinymce', {
    props: ['value'],
    data(){
        return{
            flag:true
        }
    },
    watch:{
        value(val){
            //console.log(val);
            if(this.flag){
                tinymce.activeEditor.setContent(val);
            }
            this.flag = true;
        }
    },
    mounted: function(){
        const self = this;
        tinymce.init({
            target: this.$el.children[0],
            //theme: 'modern',//inlite mobile modern
            language: "zh_CN",
            menubar: false,
            branding: false,
            valid_elements: "p[style],span[style],ul,ol,li,strong/b,em,h1,h2,h3,h4,h5,h6",
            valid_style: {
                "*":"color,font_size,text-align,line-height"
            },
            plugins: [ //配置插件：可自己随意选择，但如果是上传本地图片image和imagetools是必要的

            // images_upload_credentials:true,
            setup: function(editor) {
                editor.on('input undo redo execCommand', function(e) {
                    self.flag = false;
                    self.$emit('input', editor.getContent());
                });
            },
            images_upload_handler: function (blobInfo, success, failure) {
                //console.log(blobInfo);
                //console.log(success);
                //console.log(failure);
                let formData = new FormData();
                formData.append('file', blobInfo.blob(), blobInfo.filename());
                $.ajax({
                    url : basePath()+'/platform/res/upload/img',
                    type : "POST",
                    data : formData,
                    cache : false,
                    async : true,
                    contentType : false, // 这两句需要添加上，否则会跳转页面
                    processData : false,
                    dataType : "json",
                    success : function(obj) {
                        if(obj.code == 0){
                            console.log(obj.data.location);
                            success(obj.data.location);
                        }else{
                            failure('上传出错了');
                        }
                    },
                    error : function () {
                        failure('上传出错了，图片限制上传最大为2M');
                    }
                });
            }
        });
    },
    updated(){

    },
    created(){

    },
    destroyed(){

    },
    template: '<div><textarea style="height:300px" v-model="value"></textarea></div>'
});

自定控件 添加属性  v-if="dialogVisible"  或者使用element-ui较新的话可以在在el-dialog 标签上添加 :destroy-on-close="true"  关闭时dialog销毁dialog内的控件

<el-dialog title="" :visible.sync="dialogVisible" :append-to-body="true">
    <my-tinymce v-model="data" v-if="dialogVisible"></my-tinymce>
</el-dialog>

这样设置是为了关闭dialog时销毁my-editor控件，不销毁的话会出现问题的
