Question

对象：1

{
    "sourcePath": "vv",
    "targetPath": "bb"
}

我获得了像对象1这样的键值对，并且我已经拥有了像Object 2这样的嵌套对象

对象：2

{
"user": "hdpsrvc",
"update": "13/06/2016 17:43:22",
"template": "template_1",
"formBody": [
    {
        "tabIndex": 0,
        "type": "text",
        "name": "sourcePath",
        "label": "Source path"
    },
    {
        "tabIndex": 1,
        "type": "text",
        "name": "targetPath",
        "label": "Target path"
    }
],

}

我希望将对象1的键值对推送到如下所示的嵌套对象（请参阅formBody下的红色标记粗体键值对）

{
"user": "hdpsrvc",
"update": "13/06/2016 17:43:22",
"template": "template_1",
"formBody": [
    {
        "tabIndex": 0,
        "type": "text",
        "name": "sourcePath",
        "label": "Source path",
        "sourcePath": "vv"
    },
    {
        "tabIndex": 1,
        "type": "text",
        "name": "targetPath",
        "label": "Target path",
        "targetPath": "bb"
    }
],
}

Answer 1

如果您只有这两个值推，那么只需按照以下方式分配即可轻松完成。

假设JSON 1存储在变量var jsonOne中，而JSON 2存储在变量var jsonTwo中。然后

jsonTwo.formBody[0].sourcePath = jsonOne.sourcePath;
jsonTwo.formBody[1].targetPath = jsonOne.targetPath;

或者，如果您有更多的值要推送，那么您可以编写for循环并形成匹配的算法。在下面的代码中我与标签匹配;

for (i = 0; i < jsonTwo.formBody.length; i++) {
    var temp = jsonTwo.formBody[i].label;
    if (temp === 'Source path') {
        jsonTwo.formBody[i].sourcePath = jsonOne.sourcePath;
    } else {
        jsonTwo.formBody[i].targetPath = jsonOne.targetPath;
    }
}

你可以试试这个：

var obj1 = {
    "sourcePath": "vv",
    "targetPath": "bb"
};

var obj2 = {
"user": "hdpsrvc",
"update": "13/06/2016 17:43:22",
"template": "template_1",
"formBody": [
    {
        "tabIndex": 0,
        "type": "text",
        "name": "sourcePath",
        "label": "Source path"
    },
    {
        "tabIndex": 1,
        "type": "text",
        "name": "targetPath",
        "label": "Target path"
    }
]};

obj2.formBody = obj2.formBody.map((item , ind) => Object.assign(
  item,
  {[Object.keys(obj1)[ind]]: obj1[Object.keys(obj1)[ind]]}
));
console.log(obj2);

甚至：

var obj1 = {
    "sourcePath": "vv",
    "targetPath": "bb"
};

var obj2 = {
"user": "hdpsrvc",
"update": "13/06/2016 17:43:22",
"template": "template_1",
"formBody": [
    {
        "tabIndex": 0,
        "type": "text",
        "name": "sourcePath",
        "label": "Source path"
    },
    {
        "tabIndex": 1,
        "type": "text",
        "name": "targetPath",
        "label": "Target path"
    }
]};

obj2.formBody = obj2.formBody.map(item => Object.assign(
  item,
  {[item.name]: obj1[item.name]}
));
console.log(obj2);
