vue.runtime.esm.js:619 [Vue warn]: Error in mounted hook: "TypeError: Cannot read properties of undefined (reading 'get')"

这个错误是由于在Vue的mounted生命周期钩子函数中调用了一个undefined对象的属性get，导致出现了TypeError报错。

解决这个问题的方法是将挂载函数从created生命周期钩子函数中移至mounted生命周期钩子函数中。这样可以确保在组件的DOM元素已经被挂载到页面上后再执行该函数。

此外，需要注意检查相关的数据或方法是否正确定义和初始化，以避免出现undefined的情况。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
