js 判断数组中对象是否存在某个值 应用到some()方法

let arr = [{"pmdm": "502429","wzpm": "16绶带","year": ,"isBinding": false,"shelfTotal": 114,"tmpShelfTotal": 0,"printNum": 0},{"pmdm": "502429","wzpm": "16绶带2","year": ,"isBinding": false,"shelfTotal": 114,"tmpShelfTotal": 0}]

数组如上，对象下的printNum = 0 或者printNum不存在，进行弹窗提示

let result = arr.some(function (el, index) {//判断属性值是否存在或者是否等于0if (!el.hasOwnProperty("printNum") || el.printNum == 0) {return true;}});if (result) {this.$message("请选中打印标签物资");} else {alert("打印");}
