Question

这是我的父母

<template>
    <Chart :type="bar" :data="[2,15,3,4,5,1,2,4,10,11]"></Chart>
</template>

<script>
import Chart from "./Chart"

    export default {
     components: {
        Chart
    },
  }

</script>

这是我的孩子部分：

<template>
    <highcharts :options="chartOptions"></highcharts>
</template>

<script>
import {Chart} from 'highcharts-vue'

    export default {
      props: ["data", "type"],
      components: {
      highcharts: Chart 
    },
    data() {
      return {
        chartOptions: {
          chart: {
            type: this.type
          },
          series: [{
            data: this.data, // sample data
            name: "Test Series",
            color: "blue"
          }]
        }
      }
  }
  }
</script>

我能够通过道具传递数据，但不能传递类型。当我将type: this.type更改为type: "bar"时，它可以按预期工作，因此代码本身没有错误。

我收到以下警告：

vue.runtime.esm.js?2b0e:619 [Vue warn]: Property or method "bar" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

我在做什么错了？

Answer 1

您正在尝试将bind prop“类型”动态<Chart type="bar" :data="[2,15,3,4,5,1,2,4,10,11]"></Chart>到 bar ，好像最后一个是变量一样。如果要将其作为字符串传递，请执行以下操作：

import math
from decimal import *

pi = Decimal(3)

two = 2
three = 3
four = 4

times = 10000

for c in range(times):
    pi += Decimal(4)/two * three * four
    pi -= Decimal(4)/two + 2 * three + 2 * four + 2 * three

    two += 2
    three += 2
    four += 4

print(pi)

Answer 2

您使用：type =“ bar”以便Vue寻找一个称为“ bar”的变量。如果要将值作为字符串传递，则应在“类型”之前删除“：”。

<template>
    <Chart type="bar" :data="[2,15,3,4,5,1,2,4,10,11]"></Chart>
</template>

VueJS-无法将道具从父组件传递到子组件
