[
"criteriaName": "CRITERIA 1",
"criteriaType": "Dependent",
"table": "Table1",
"column": "Column1",
"joinType": "OR",
"operator": ">=",
"valueType": "SQL",
"dataType": "NUMBER",
"format": "Config",
"parameterMandatory": "YES",
"link": "KB",
"sequence": "SEQ1",
"value": "VAL",
"description": "abcde"
]
我试图从上面的数组中将每个值添加到下面的嵌套对象中。
需要将上面数组中的每个值添加到下面数组中的每个模型中 下面是目标数组。
我试图将上面的数组值添加到下面
formFields = [
"title": "Criteria Details",
"columns": 2,
"fields":
"criteriaName":
"type": "text",
"label": "Criteria Name",
"id": 'criteriaName',
"model": "",

v => !!v || 'Criteria Name is required',
]
,

v => !!v || 'Value Type is required',

v => !!v || 'Parameter Mandatory is required',
],
"show": true,

"id": "link",
"options": ["KB"],
"model": "",

,
"sequence":
'type': "text",
"label": "Sequence",
"id": "sequence",

v => !!v || 'Sequence is required',
],

,
'title': "Notes",
"columns": 1,
"fields":
"description":
"type": "description_notes",
"label": "Description",
"id": "description",
"required": false,
"model": '',
"show": true,
]
我怎样才能做到这一点？
谢谢你..
【问题讨论】：
你能举一个预期输出的例子吗？并且不要转储列表 - 可能为了这个问题而简化（减少）数组中的项目数量 - 它更容易推理，并且适用于 2 元素数组的方法也适用于更长的数组。跨度> 【参考方案1】：我相信这就是你想要的：
yourFirstArray.forEach(function(e)
formFields.forEach(function(fF)
var firstKey = Object.keys(e)[0]; // taking first key of each object in your first array (0)
fF[firstKey] = e[firstKey];
)
)
【讨论】：
【参考方案2】：解决方案：
var temp = modelValues.reduce((acc, modelValue) => Object.assign(, acc, modelValue), );
Object.keys(temp).forEach(key => formFields[key].model = temp[key])
注意：modelValues 是你的数组
但是，我建议你像这样改变你的结构？
var modelValues =
criteriaName: "CRITERIA 1",
criteriaType: "Dependent",
table: "Table1",
column: "Column1",
joinType: "OR",
operator: ">=",
valueType: "SQL",
dataType: "NUMBER",
format: "Config",
parameterMandatory: "YES",
link: "KB",
sequence: "SEQ1",
value: "VAL",
description: "abcde"
;
并这样做以映射值
Object.keys(modelValues).forEach(key => formFields[key].model = modelValues[key])
