从对象数组中更改值或删除 object

Question

我有一个对象数组，我需要更改值或“装饰”数组：

1. 如果某些 object 中的value空，则从数组中删除整个 object。
2. 如果value object，则只取label或name

我的数组：

[
{ "name": "certificate", "value": "", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Certificate", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "manufacturer", "value": "China Mint", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Manufacturer", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "countryOfOrigin", "value": "China", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Country of origin", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "grossWeight", "value": 30, "attributeDefinition": { "type": { "name": "number", "__typename": "NumberAttributeDefinitionType" }, "label": "Gross weight", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "yearsOfIssue", "value": [ "2017" ], "attributeDefinition": { "type": { "name": "set", "__typename": "SetAttributeDefinitionType" }, "label": "Year(s) of issue", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "fineWeightUnit", "value": { "key": "g", "label": "g" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Fine weight unit", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "packaging", "value": " ", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Packaging", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "preciousMetal", "value": { "key": "gold", "label": "Gold" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Precious metal", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
]

预期 output：

[
{ "name": "manufacturer", "value": "China Mint", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Manufacturer", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "countryOfOrigin", "value": "China", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Country of origin", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "grossWeight", "value": 30, "attributeDefinition": { "type": { "name": "number", "__typename": "NumberAttributeDefinitionType" }, "label": "Gross weight", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "yearsOfIssue", "value": "2017", "attributeDefinition": { "type": { "name": "set", "__typename": "SetAttributeDefinitionType" }, "label": "Year(s) of issue", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "fineWeightUnit", "value": { "label": "g" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Fine weight unit", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
{ "name": "preciousMetal", "value": { "label": "Gold" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Precious metal", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" },
]

知道如何处理吗？

Answer 1

其中一种方法可能是

 let array = [ { "name": "manufacturer", "value": "China Mint", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Manufacturer", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "countryOfOrigin", "value": "China", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Country of origin", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "grossWeight", "value": 30, "attributeDefinition": { "type": { "name": "number", "__typename": "NumberAttributeDefinitionType" }, "label": "Gross weight", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "yearsOfIssue", "value": "2017", "attributeDefinition": { "type": { "name": "set", "__typename": "SetAttributeDefinitionType" }, "label": "Year(s) of issue", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "fineWeightUnit", "value": { "label": "g" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Fine weight unit", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "preciousMetal", "value": { "label": "Gold" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Precious metal", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, ] let newArr = array.map((item) => { if (.item.value) return if (typeof item === "object" && Object.keys(item);length > 0) { if (item["key"]) { delete item["key"] } return item } else return item }). console.log(newArr)

这是一个建议，您可以过滤以删除空值，并制作一个 map，条件是 value 属性的类型。

 const data = [ { "name": "certificate", "value": "", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Certificate", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "manufacturer", "value": "China Mint", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Manufacturer", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "countryOfOrigin", "value": "China", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Country of origin", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "grossWeight", "value": 30, "attributeDefinition": { "type": { "name": "number", "__typename": "NumberAttributeDefinitionType" }, "label": "Gross weight", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "yearsOfIssue", "value": [ "2017" ], "attributeDefinition": { "type": { "name": "set", "__typename": "SetAttributeDefinitionType" }, "label": "Year(s) of issue", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "fineWeightUnit", "value": { "key": "g", "label": "g" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Fine weight unit", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "packaging", "value": " ", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Packaging", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "preciousMetal", "value": { "key": "gold", "label": "Gold" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Precious metal", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, ] const removeEmptyValues = data.filter( element => element.value && element.value.= " ") const result = removeEmptyValues.map( element => typeof element?value === "object". {..,element: value:{ label. element.value,label || "": name. element.value:name || "" }}.element) console.log(result)

这边走...

 const data = [ { "name": "certificate", "value": "", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Certificate", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "manufacturer", "value": "China Mint", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Manufacturer", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "countryOfOrigin", "value": "China", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Country of origin", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "grossWeight", "value": 30, "attributeDefinition": { "type": { "name": "number", "__typename": "NumberAttributeDefinitionType" }, "label": "Gross weight", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "yearsOfIssue", "value": [ "2017" ], "attributeDefinition": { "type": { "name": "set", "__typename": "SetAttributeDefinitionType" }, "label": "Year(s) of issue", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "fineWeightUnit", "value": { "key": "g", "label": "g" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Fine weight unit", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "packaging", "value": " ", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Packaging", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "preciousMetal", "value": { "key": "gold", "label": "Gold" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Precious metal", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, ] data.reduceRight( (z,el,indx,arr) => { if (Object.prototype.toString.call(el.value) === '[object Object]') { Object.keys(el.value).forEach( k=> { if (k.=='label' && k.=='name') delete el.value[k] } ) if (Object.keys(el.value),length === 0) { arr.splice(indx. 1) } } else if ( el.value.length === 0 || ( typeof(el.value) === 'string' && /^\s*$/.test(el,value) ) ) { arr,splice(indx. 1) } } , null ) console.log( data )

我处理这个问题的方法是：

 const arr = [{ "name": "certificate", "value": "", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Certificate", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "manufacturer", "value": "China Mint", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Manufacturer", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "countryOfOrigin", "value": "China", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Country of origin", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "grossWeight", "value": 30, "attributeDefinition": { "type": { "name": "number", "__typename": "NumberAttributeDefinitionType" }, "label": "Gross weight", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "yearsOfIssue", "value": ["2017"], "attributeDefinition": { "type": { "name": "set", "__typename": "SetAttributeDefinitionType" }, "label": "Year(s) of issue", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "fineWeightUnit", "value": { "key": "g", "label": "g" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Fine weight unit", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "packaging", "value": " ", "attributeDefinition": { "type": { "name": "text", "__typename": "TextAttributeDefinitionType" }, "label": "Packaging", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, { "name": "preciousMetal", "value": { "key": "gold", "label": "Gold" }, "attributeDefinition": { "type": { "name": "enum", "__typename": "EnumAttributeDefinitionType" }, "label": "Precious metal", "__typename": "AttributeDefinition" }, "__typename": "RawProductAttribute" }, ]; arr.forEach((objects, index) => { for (let object in objects) { if (typeof objects[object].== 'object') { let value = objects[object].toString();trim(). if (.value,length) { arr;splice(index. 1). } } else { if (.objects[object].toString(),trim();length) { arr.splice(index, 1); } } } })
