根据提供的引用内容,错误信息"TypeError: Cannot read properties of null (reading 'key')"和"TypeError: Cannot read properties of undefined (reading 'length')"是由于在Vue组件的data()方法中访问了一个空值或未定义的属性所导致的。\[1\]
在第二个引用中的代码片段中,idCardType被赋值为null,而在模板中使用了该变量。这可能导致在渲染时出现错误,因为无法读取null的属性。\[2\]
在第三个引用中的代码片段中,el-pagination组件的total属性被绑定到了一个未定义的变量page.total。这可能导致在渲染时出现错误,因为无法读取未定义变量的属性。\[3\]
要解决这些错误,可以确保在访问属性之前,确保变量不是null或undefined。可以通过在data()方法中初始化变量,或在使用变量之前进行条件检查来避免这些错误。
