今天遇到一种服务端响应的参数,key是动态的 就像这样 我们一般静态key取值就是直接 data.data.id.username 但这种id是动态的 我们就只能用for in的方式取值了 var data

有一段时间没用sqoop了,今天打开进行测试的时候,发现命令行总是出现下面这样的警示信息: Warning: /opt/module/sqoop/bin/…/…/hcatalog does not exist...Warning: /opt/module/sqoop/bin/…/…/accumulo does not exist! Accumulo imports will fail.
例如:const obj = { key: 'value'}; console.log('key' in obj); // trueconsole.log('anotherKey' in obj);...例如:const obj = { key: 'value'}; console.log(obj.hasOwnProperty('key')); // trueconsole.log(obj.hasOwnProperty...anotherKey')); // false3.使用Object.keys方法:Object.keys返回一个给定对象自身可枚举属性的字符串数组,然后可以通过数组的includes方法判断是否包含某个key...例如:const obj = { key: 'value'}; console.log(Object.keys(obj).includes('key')); // trueconsole.log(Object.keys
1.解决ie浏览器的兼容性问题 // 通过map的value找key(ps:obj是js中的map对象 value就是map中的value) function findKey (obj,value...find()方法还是解决ie不兼容问题 return compare(obj[k],value); }); } 2.直接使用lambda表达式 // 通过map的value找key...(ps:obj是js中的map对象 value就是map中的value) function findKey (obj,value, compare = (a, b) => a === b) {...return Object.keys(obj).find(k => compare(obj[k], value)) } 值得注意的地方: 1、参数obj就是你的map对象,value就是你要查找key
