【问题描述】：

我正在尝试将下面数组中的值添加到另一个数组中

[
    {"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": {

    }
]

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>

【解决方案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];
    })
})

【解决方案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])
