Error in v-on handler: "TypeError: Cannot read properties of undefined (reading '$refs')" found in

引用:在Vue中，当使用v-on绑定的事件处理函数中出现"TypeError: Cannot read properties of undefined (reading '$refs')"的错误时，可能是由于在事件处理函数中尝试访问未定义的$refs属性。这通常是因为在事件处理函数中使用了this.$refs来访问组件的引用，但是该组件的引用还未被正确地定义或绑定。引用:解决这个问题的一种方法是确保在访问this.$refs之前，组件的引用已经被正确地定义或绑定。可以通过在组件的mounted生命周期钩子函数中执行相关的绑定操作来确保组件引用的正确性。引用:另外，还需要注意的是，当访问this.$refs时，要确保所访问的组件在模板中已经正确地使用了ref属性并赋予了唯一的标识符。只有这样，才能正确地使用this.$refs来访问组件的引用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
