  console.log(num)
 }
}]);

4. formlayoutdirective.js

'use strict';
angular.module('form.layout', [])
/**
 * 定义布局的服务
 * @method
 * @param {Object} ) this.defaultTemplate [布局的模板]
 * @return {[type]}  [description]
 */
.provider('formLayout', function(){
 // 定义布局构造函数 
 function FormLayoutFn(){
  /**
   * 定义表单元素的模板
   * @type {{text: string, radio: string, checkbox: string, remember: string, range: string, time: string, date: string, datetime: string, search: string, select: string}}
   */
  this.elementTemplate = {
    text : '\
