Error in mounted hook: "TypeError: Cannot read properties of undefined (reading 'getAttribute')"

这个错误是因为在mounted钩子函数中，尝试读取一个未定义的属性'getAttribute'引起的。根据引用的描述，这个错误可能是由于在配置Echarts地图时，使用了错误的元素ID。你可以使用Vue中的ref和$refs来代替document.getElementById()来获取图形容器对象，如引用所示。通过给div元素添加ref属性，然后在mounted钩子函数中使用this.$refs['equan']来获取该图形容器对象。这样可以避免因为ID值错误而导致的属性读取错误。请确保div元素的ref属性与mounted钩子函数中的引用名称一致。另外，根据引用的描述，也要确保div元素的id属性与调用的地图配置中的ID值保持一致。这样就能够正确配置地图并避免TypeError错误的发生。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
