Question

我是vue的新手，所以我有几个建议，即时通讯显示了一个表格，其中包含我从Web服务获得的一些数据，问题是，我不一定总是获得相同数量的数据，因此数据会输入数组，例如这样

var todos = [
    {name : "dexter" , color : "orange"},
    {name : "jaime", color : "green" },
    {name : "stack", color : "yellow" },
    {name : "overflow", color : "black" }
]

但是正如我所说，我始终没有得到包含2个项目的回复，现在我必须声明要调用te数组中的项目，并且我想调用数组中的所有项目以显示它们

var todos = [

  {
    name: "dexter",
    color: "orange"
  },
  {
    name: "jaime",
    color: "green"
  },
  {
    name: "stack",
    color: "yellow"
  },
  {
    name: "overflow",
    color: "black"
  }
]



var i = 0;
var sixthTable = new Vue({

  el: '#sevenTable',
  data: {
    currentPage: 1,
    elementsPerPage: 3,
    ascending: false,

      },

        color: todos[3].color
      }
    ]

这是我的完整代码，我知道我的数组实际上不是Web服务响应，我以这种方式“简化”了代码

感谢建议

Answer 1

您可以像这样在您的data中直接分配由Web服务提供的数据

rows: todos

使用vue显示动态数组
