首先我发布我的代码

import { Injectable } from '@angular/core';
import { Http, Headers, Response } from '@angular/http';

@Component({
 styles: [],
 template: ""
})
export class PageService {


constructor(private http: Http) {}


    getAllPage() {
            //noinspection TypeScriptUnresolvedFunction
            return this.http.get(window.location.origin + "/app/json/profile.json").map(res => res.json());
    }
}

JSON：

[  
   {  
      "groupID":1,
      "groupName":"GESTORE_PRATICHE",
      "groupDescr":"GESTORE PRATICHE",
      "functionList":[
         {  
            "id":1,
            "value":"canViewFolderManagement"
         }
         ] 

   },
   {  
      "groupID":2,

            "id":1,
            "value":"canViewFolderManagement"

         {  
            "id":2,
            "value":"canViewAdministrationManagement"
         },
         {

            "id":4,

         {

            "value":"canViewAdministrationManagement"
         }
      ]
   }
]

最后我得到以下结果：

如何在functionList列中查看数据？我的代码不能正常工作，它只保留第一级json数据。感谢

Answer 1

我已使用valuePrepareFunction: (cell,row)修正了此错误。

您可以在列设置中使用以下代码

functionList: {
    title: 'Function List',
    type:'html',
    valuePrepareFunction: (cell,row) => {
        var valueModelList = JSON.parse(row.functionList);
        var htmlEntity ="";
        valueModelList.foreach(valueModel=>{
            htmlEntity += valueModel.id+ " : " + valueModel.value + '<br>';
        })
        return htmlEntity;
    }
}

我希望它有效

Answer 2

您有 2 个选项：使用自定义渲染组件，或映射列的行值。如果是简单的嵌入值，2nd 对我来说更可取。请参阅示例：categoryLabel 和 categoryName：

settings = {
    add: {
        addButtonContent: '<i class="nb-plus"></i>',
        createButtonContent: '<i class="nb-checkmark"></i>',
        cancelButtonContent: '<i class="nb-close"></i>',
    },
    edit: {
        editButtonContent: '<i class="nb-edit"></i>',
        saveButtonContent: '<i class="nb-checkmark"></i>',
        cancelButtonContent: '<i class="nb-close"></i>',
    },
    delete: {
        deleteButtonContent: '<i class="nb-trash"></i>',
        confirmDelete: true,
    },
    columns: {
        categoryLabel: {
            title: 'Category Label',
            valuePrepareFunction: (cell, row) => row.category.label,
        },
        categoryName: {
            title: 'Category Name',
            valuePrepareFunction: (cell, row) => row.category.name,
        },
        likes: {
            title: 'Likes Amount',
        },

表Angular 2（ng2-smart-table） - 从JSON获取所有数据（对于json的每个级别）
