20个必会的JavaScript面试题(小结)

问题1:JavaScript 中 undefined 和 not defined 的区别 JavaScript 未声明变量直接使用会抛出异常：var name is not defined，如果没有处理异常，代码就停止运行了。但是，使用typeof undeclared_variable并不会产生异常，会直接返回 undefined。 var x; // 声明 x console.log(x); //output: undefined console.log(typeof y); //output: undefined console.log(z); // 抛出异常: Referen

根据引用的内容，问题出现在代码中的"options"变量未定义。请检查代码中是否有定义"options"变量，并确保代码中引用的变量名与定义的变量名一致。123 #### 引用[.reference_title] - *1* [Uncaught ReferenceError: axois is not defined](https://blog.csdn.net/qq_41425646/article/details/129861414)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v92^chatsearchT3_1"}}] [.reference_item style="max-width: 33.333333333333336%"] - *2* [echarts树状图报错option](https://blog.csdn.net/weixin_45738653/article/details/107007645)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v92^chatsearchT3_1"}}] [.reference_item style="max-width: 33.333333333333336%"] - *3* [微信小程序ReferenceError：xxx is not defined报错](https://blog.csdn.net/henry594xiaoli/article/details/129966373)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v92^chatsearchT3_1"}}] [.reference_item style="max-width: 33.333333333333336%"] [ .reference_list ]
