Question

有一个Javascript对象（formData），我需要通过与另一个对象（dataObject）进行比较来替换一些值。两个对象的JSON如下。现在我需要的是，摘录：

主formData对象：

{
                "name": "abNotes",
                "label": "Ab Notes: (Optional)",
                "type": "TEXT_BOX_SINGLE",
                "value": "Example Notes",
                "active": true
}

我需要通过“name”属性将“value”与其他dataObject进行比较，如果它不同则替换。

要与之比较的dataObject：

{
        "name": "abNotes",
        "value": "Example Notes 123456"
}

因此替换的FormData对象将更改为：

{
                    "name": "abNotes",
                    "label": "Ab Notes: (Optional)",
                    "type": "TEXT_BOX_SINGLE",
                    "value": "Example Notes 123456",
                    "active": true
}

需要更换的主要对象

JSON.stringify (formData);

form data::
{
    "name": "Demo",
    "fieldGroupList": [{
        "name": "instructions",
        "label": "Instructions",
        "fieldList": [{
            "name": "INSTRUCTION",
            "instructionList": [{
                "instructionText": "All enabled fields are required."
            }],
            "type": "INSTRUCTION"
        }]
    },
    {
        "name": "ab",
        "label": "Ab",
        "fieldList": [{

            "value": "1425186000000",
            "active": true
        },
        {
            "name": "abNotes",
            "label": "Ab Notes: (Optional)",
            "type": "TEXT_BOX_SINGLE",

    },

            },
            {
                "name": "No",
                "value": "false"
            }],
            "active": true
        },
        {
            "name": "exclusionReasonCode",
            "instructionList": [{
                "instructionText": "Select from the following list of sample:"
            }],
            "type": "SINGLE_FROM_SET",
            "value": "DCS",
            "optionList": [{
                "name": "DCS",
                "value": "Test"
            }],
            "active": true
        }]
    },
    {
        "name": "bDemo",
        "label": "Demo",
        "fieldList": [{
            "name": "mId",
            "label": "M ID:",
            "type": "TEXT_BOX_SINGLE",
            "active": false
        },
        {
            "name": "firstName",
            "label": "First Name:",
            "type": "TEXT_BOX_SINGLE",
            "value": "John",
            "active": true
        },
        {
            "name": "lastName",
            "label": "Last Name",
            "type": "TEXT_BOX_SINGLE",
            "value": "Doe",
            "active": true
        },
        {
            "name": "genderCode",
            "instructionList": [{
                "instructionText": "Gender:"
            }],
            "type": "SINGLE_FROM_SET",
            "optionList": [{
                "name": "FEMALE",
                "value": "FEMALE"
            },
            {
                "name": "MALE",
                "value": "MALE"
            },
            {
                "name": "UNKNOWN",
                "value": "UNKNOWN"
            }],
            "active": true
        },
        {
            "name": "dateOfBirth",
            "label": "Date of Birth:",
            "type": "DATE",
            "value": "-157748400000",
            "active": true
        }]
    },
    {
        "name": "generalComments",
        "label": "General Comments",
        "fieldList": [{
            "name": "comments",
            "label": "Comments: (Optional)",
            "type": "TEXT_BOX_MULTIPLE",
            "value": "Comments Text Example",
            "active": true
        }]
    }],
    "Id": 1,
    "periodId": 2015,
    "orgId": 4,
    "version": 1
}

此对象需要的值：

var dataObject = $('#'+formName).serializeArray();
console.log("data:::"+JSON.stringify(dataObject));

dataObject:::
[{
    "name": "abDate",
    "value": "Sun Mar 01 2015 00:00:00 GMT-0500 (Eastern Standard Time)"
},
{
    "name": "abNotes",
    "value": "Example Notes 123456"
},
{
    "name": "Number",
    "value": "1234567890"
},
{
    "name": "otherNumber",
    "value": "887766"
},
{
    "name": "Yes",
    "value": "true"
},
{
    "name": "No",
    "value": "false"
},
{
    "name": "DCS",
    "value": "Test"
},
{
    "name": "firstName",
    "value": "John"
},
{
    "name": "lastName",
    "value": "Doe"
},
{
    "name": "FEMALE",
    "value": "FEMALE"
},
{
    "name": "MALE",
    "value": "MALE"
},
{
    "name": "UNKNOWN",
    "value": "UNKNOWN"
},
{
    "name": "dateOfBirth",
    "value": "Fri Jan 01 1965 00:00:00 GMT-0500 (Eastern Standard Time)"
},
{
    "name": "comments",
    "value": "Comments Text Example"
}]

修改

到目前为止我尝试过：

$.extend(formData ,dataObject);
deepcopy的：

function deepCopy（src，dest）{ var名称，值， IsArray的， toString = Object.prototype.toString;

// If no `dest`, create one
if (!dest) {
    isArray = toString.call(src) === "[object Array]";
    if (isArray) {
        dest = [];
        dest.length = src.length;
    }
    else { // You could have lots of checks here for other types of objects
        dest = {};
    }
}

// Loop through the props
for (name in src) {
    // If you don't want to copy inherited properties, add a `hasOwnProperty` check here
    // In our case, we only do that for arrays, but it depends on your needs
    if (!isArray || src.hasOwnProperty(name)) {
        value = src[name];
        if (typeof value === "object") {
            // Recurse
            value = deepCopy(value);
        }
        dest[name] = value;
    }
}

return dest;

}

Answer 1

首先，将dataObject从对象数组转换为将名称映射到值的对象。然后浏览主表单数据，替换doHash的相应元素中的值。

var formData = {
  "name": "Demo",
  "fieldGroupList": [{
    "name": "instructions",
    "label": "Instructions",
    "fieldList": [{
      "name": "INSTRUCTION",
      "instructionList": [{
        "instructionText": "All enabled fields are required."
      }],
      "type": "INSTRUCTION"
    }]
  }, {
    "name": "ab",
    "label": "Ab",
    "fieldList": [{
      "name": "abDate",
      "label": "Ab Date",
      "type": "DATE",
      "value": "1425186000000",
      "active": true
    }, {
      "name": "abNotes",
      "label": "Ab Notes: (Optional)",
      "type": "TEXT_BOX_SINGLE",
      "value": "Example Notes",
      "active": true
    }]
  }, {
    "name": "Record",
    "label": "Record",
    "fieldList": [{
      "name": "RecordNumber",
      "label": "Record Number: (Optional)",
