摘要： Vue.js开发中常见的Property or method is not defined错误通常是由于未在data中定义响应式数据、未在methods中定义方法、拼写错误或作用域问题导致的。解决方案包括：1) 在data中预先定义所有响应式数据；2) 在methods中明确定义方法；3) 检查属性/方法名称的拼写一致性；4) 正确处理v-for循环作用域。文章通过代码示例和对比表格详细分析了错误原因及解决方法，强调严谨的数据定义和使用Vue开发者工具的重要性，帮助开发者有效避免这类响应式数据问题。

报错翻译：属性或方法“password”未在实例上定义，但在渲染过程中被引用。通俗来讲就是，你在html中用了password属性，但是在js部分没有定义。解决措施：在 script 中的 data 或 method 中添加相关属性。或者是检查 template 部分的属性引用是否正确，层级关系是否正确。这里以调用element-ui中的input标签为例，检查属性是否定义，检查属性层级是否正确。以下标红框的是报错的根源。

如果xxx 方法确实已经定义在 Vue 组件的方法选项中，那么这通常意味着该方法所在的组件实例没有正确地挂载或初始化。如果以上步骤都没有解决问题，建议检查整个组件的代码，特别是 methods 部分和模板部分，确保所有部分都正确无误。确保在模板中调用 xxx 方法的地方拼写正确，并且没有拼写错误。确保xxx 方法位于 Vue 组件的 methods 选项中。如果你在父组件中使用了这个子组件，确保子组件已正确注册并导入。报错信息意为：报错信息提示xxx 方法未定义，确认 xxx 方法没有被其他同名方法覆盖。
