如何将类型对象的数据转换为JSON对象

Question

嗨，我使用angularjs，当我打印此行

 console.log(JSON.stringify($scope.data));

我正在浏览器控制台中获取以下数据

"FirstName,LastName,CII Number,Document Path\r\nJohn1,Rambo1,bulktest1,D:/MyDOJ/input_2/1000.pdf\r\nJohn2,Rambo2,bulktest2,D:/MyDOJ/input_2/1020.pdf\r\nJohn3,Rambo3,bulktest3,D:/MyDOJ/input_2/1010.pdf\r\nJohn4,Rambo4,bulktest4,D:/MyDOJ/input_2/5010.pdf\r\n"

我想将此数据形成为JSON对象，如下所示

[{ "FirstName":"John1" , "LastName":"Rambo1" ...},
{ "FirstName":"John2" , "LastName":"Rambo2" ...},
{ "FirstName":"John3" , "LastName":"Rambo3" ...}] etc

请建议我该怎么做。

$scope.data是包含逗号分隔值的字符串，您必须首先将其转换为对象。

function parseCSV(csv) {
    var rows = csv.split('\r\n'), //Split the CSV into rows
        keys = rows.shift().split(','), //First row contains keys, so we take that out of rows
        out = []; //output array
    rows.forEach(function (row) {
        var obj = {}; //object for our row
        row.split(',').forEach(function (value, index) {
            obj[keys[index]] = value; //use the key in keys and set the value
        });
        out.push(obj); //add object to out
    });
    return out;
}
var object = parseCSV($scope.data);
console.log('object', object);
console.log('json string', JSON.stringify(object));
