数据如下，每一项的image根据attributeValue来赋值,所有的arrtibuteValue1相同值的image是一样的，比如第一项attributeValue1的值是"P.Ⅰ", 并且这一条的image是有值的话那么所有attributeValue1 等于p.I 的image都被赋值，attributeValue1的值会有多个，相同值的image是一样的，如果attributeValue1的image都没有值得话，以此类推attribute2,3,4... 优先级按照数字的顺序,应该如何修改，感谢各位
let arr = [

"uniqueCategoryKey": "11,21,31",
"attributeName1": "种类1",
"attributeValue1": "P.Ⅰ",
"attributeName2": "强度2",
"attributeValue2": "32.5",
"attributeName3": "其他",
"attributeValue3": "免税"
},

"attributeValue1": "P.Ⅱ",
"attributeName2": "强度2",
"attributeValue2": "32.5",
"attributeName3": "其他",
"attributeValue3": "缓凝"
}
]
想要的数据格式，相同attributeValue1这一项的image是相同的，优先去找attributeValue1的image如果没有继续往下找，以此类推
