Question

这是我已经拥有的架构文件。

function handleFiles(files) {
  for (var i = 0; i < files.length; i++) {
    var file = files[i];
    var imageType = /^image\//;

    if (!imageType.test(file.type)) {
      continue;
    }

    var img = document.createElement("img");
    img.classList.add("obj");
    img.file = file;
    preview.appendChild(img); // Assuming that "preview" is the div output where the content will be displayed.

    var reader = new FileReader();
    reader.onload = (function(aImg) { return function(e) { aImg.src = e.target.result; }; })(img);
    reader.readAsDataURL(file);
  }
}

当我将bewlow两个文件添加到架构中的文件

时

 // defining a mongoose schema 
 // including the module 
  var mongoose = require('mongoose'); 
 // declare schema object. 
 var Schema = mongoose.Schema; 

 var blogSchema = new Schema({ 

 title : {type:String,default:'',required:true }, 
  subTitle : {type:String,default:''}, 
 blogBody : {type:String,default:''}, 
 tags   : [],// name of tags in array 
 created    : {type:Date}, 
 lastModified : {type:Date}, 
 authorInfo  :  {} // information of author in form of obje-ct 
 }); 

 mongoose.model('Blog',blogSchema);

在app.js中保存文件并运行命令节点app.js之后如下所示抛出错误，即使安装了所有软件包

，我也在运行此文件

  userName : {type:String,default:''} ,
  passWord : {type:String,default:''} 

 like

 // defining a mongoose schema 
 // including the module 
 var mongoose = require('mongoose'); 
 // declare schema object. 
 var Schema = mongoose.Schema; 

 var blogSchema = new Schema({ 

 title : {type:String,default:'',required:true}, 
  subTitle : {type:String,default:''}, 
  blogBody : {type:String,default:''}, 
  tags : [],// name of tags in array 
  created : {type:Date}, 
  lastModified : {type:Date}, 
  authorInfo  :  {} // information of author in form of obje-ct 
 userName : {type:String,default:''} ,----------------------------------here
  passWord : {type:String,default:''} ----------------------------------here
 });

在模式文件中添加字段会在执行文件时产生错误
