我有这个JSON数据:
{
"employees": [
{
"firstName": "John",
"lastName": "Doe"
},
{
"firstName": "Anna",
"lastName": "Smith"
},
{
"firstName": "Peter",
"lastName": "Jones"
}
]
}
假设我不知道我有多少列和行的员工,如何在JavaScript中创建此对象(没有连接字符串)?假设我在“onGeneratedRow”方法中获取每一行,并且我需要将每一列(firstName,lastName)推送到“{}”括号。
var viewData = {
employees : []
};
var rowNum = -1;
function onGeneratedRow(columnsResult)
{
rowNum = rowNum + 1;
viewData.employees.push({});
columnsResult.forEach(function(column) {
var columnName = column.metadata.colName;
viewData.employees[rowNum][columnName] = column.value; });
}

这就是你所需要的!
function onGeneratedRow(columnsResult)
{
var jsonData = {};
columnsResult.forEach(function(column)
{
var columnName = column.metadata.colName;
jsonData[columnName] = column.value;
});
viewData.employees.push(jsonData);
}

也许这些信息会对您有所帮助。
var sitePersonel = {};
var employees = []
sitePersonel.employees = employees;
console.log(sitePersonel);
var firstName = "John";
var lastName = "Smith";
var employee = {
"firstName": firstName,
"lastName": lastName
}
sitePersonel.employees.push(employee);
console.log(sitePersonel);
var manager = "Jane Doe";
sitePersonel.employees[0].manager = manager;
console.log(sitePersonel);
console.log(JSON.stringify(sitePersonel));

本主题,尤其是Xotic750的答案对我非常有帮助。我想生成一个json变量,使用ajax将其传递给php脚本。我的值存储在两个数组中,我希望它们采用json格式。 这是一个通用的例子:
valArray1 = [121, 324, 42, 31];
valArray2 = [232, 131, 443];
myJson = {objArray1: {}, objArray2: {}};
for (var k = 1; k < valArray1.length; k++) {
var objName = 'obj' + k;
var objValue = valArray1[k];
myJson.objArray1[objName] = objValue;
}
for (var k = 1; k < valArray2.length; k++) {
var objName = 'obj' + k;
var objValue = valArray2[k];
myJson.objArray2[objName] = objValue;
}
console.log(JSON.stringify(myJson));
控制台日志中的结果应该是这样的:
{
"objArray1": {
"obj1": 121,
"obj2": 324,
"obj3": 42,
"obj4": 31
},
"objArray2": {
"obj1": 232,
"obj2": 131,
"obj3": 443
}
}

JavaScript
var myObj = {
id: "c001",
name: "Hello Test"
}
Result(JSON)
{
"id": "c001",
"name": "Hello Test"
}
