eg1（数组中包含的是数组）:

var jsonData = {};

var arr = [[1, 'boy', 'dabing'], [2, 'girl', 'dabing']];

for (var i = 0; i < arr.length; i++) {

    var key = arr[i][1];

    var value = arr[i][2];

    jsonData[key] = value;

}

console.log(jsonData['boy'])// 'dabing'

eg2（数组中包含的是对象）:

var jsonData = {};

var arr = [ { id: 3, name: 'MAN_MIDDLESCHOOL_STUDENT', value: 'predefine' },

            { id: 4, name: 'FEMALE_MIDDLESCHOOL_STUDENT', value: 'predefine' }];

for (var i = 0; i < arr.length; i++) {

    var key = arr[i].name;

    var value = arr[i].value;

    jsonData[key] = value;

}

console.log(jsonData);//{ MAN_MIDDLESCHOOL_STUDENT: 'predefine', FEMALE_MIDDLESCHOOL_STUDENT: 'predefine' }
