解決Echart報錯Uncaught?TypeError:Cannot?read?properties?of?undefined(reading?‘type‘)問題

更新時間：2025年11月22日 14:00:56 作者：毛三仙

使用ECharts時,通過ResizeObserver監(jiān)聽父元素寬高變化可能會導致報錯,這是因為ECharts在Vue內(nèi)部被轉(zhuǎn)換為響應式對象,導致在resize時無法正確獲取響應式API,解決方法是使用`markRaw`標記對象為不可響應,或者升級ECharts版本至5.3.2及以上,以修復相關(guān)bug

Echart報錯Uncaught TypeError:Cannot read properties of undefined(reading ‘type‘)

報錯情況，使用了ResizeObserver監(jiān)聽了echart父元素寬高變化，然后就出現(xiàn)了以下兩種報錯。

使用echart 報錯 Uncaught TypeError: Cannot read properties of undefined (reading ‘type’)

報錯截圖

echart會被在vue內(nèi)部轉(zhuǎn)換成響應式對象，從而在resize 的時候獲取不到

使用 vue3的API , markRaw，標記一個對象，使其不能成為一個響應式對象

import { markRaw } from "vue";

let myChart = ref(null)
let chartElement = document.getElementById(“chart”)
myChart.value = markRaw(echarts.init(chartElement))

鼠標放在圖表上或者拖拽底部minMax欄也會報錯；“echarts”: “^5.3.2”
