在我的角度应用中,我有两个数组,如下所示:
$scope.data = ["val 10,val 11,val 12", "val 20,val 21,val 22", "val 30,val 31,val 32"];
$scope.fields = [ "key1", "key2", "key3" ];
现在我需要使用以下格式将数组($scope.data
)的每个数据发送到服务器:
{
key1: 'val 10',
key2: 'val 11',
key2: 'val 12',
}
{
key1: 'val 20',
key2: 'val 21',
key2: 'val 22',
}
{
key1: 'val 30',
key2: 'val 31',
key2: 'val 32',
}
但问题是:当我向服务器发送数据时,我只获得$scope.data
的最后一个值。我的代码如下:
// $scope.data = ["val 10,val 11,val 12", "val 20,val 21,val 22", "val 30,val 31,val 32"];
_.each($scope.data, function(result, index) {
var dataArray = result.split(","); // ["val 10" ,"val 11", "val 12"]
// ["val 20" ,"val 21", "val 22"]
// ["val 30" ,"val 31", "val 32"]
_.each(dataArray, function(info, position) {
if( info !== null || info !== '' || info.length > 0 ) {
$scope.data[ $scope.fields[position] ] = info; // { key1: 'val 10', key2: 'val 11', key2: 'val 12' }
// { key1: 'val 20', key2: 'val 21', key2: 'val 22' }
// { key1: 'val 30', key2: 'val 31', key2: 'val 32' }
}
});
$http
.post(url + '/import-data', {
"data": $scope.data
})
.then(function (res) {
console.log(res); // in server I always get the following object
// { key1: 'val 30', key2: 'val 31', key2: 'val 32' }
// { key1: 'val 30', key2: 'val 31', key2: 'val 32' }
// { key1: 'val 30', key2: 'val 31', key2: 'val 32' }
}, function (error) {
console.log("error : ", error);
})
});
我该如何解决这个问题?在此先感谢...

我为你创建了一个名为$scope.serverdata
的新变量。将其传递给服务器。
$scope.data = ["val 10,val 11,val 12", "val 20,val 21,val 22", "val 30,val 31,val 32"];
$scope.fields = ["key1", "key2", "key3"];
$scope.serverdata = [];
angular.forEach($scope.data, function(result) {
var dataArray = result.split(",");
var value = {};
angular.forEach($scope.fields, function(field, index) {
if (value[field] == undefined) {
value[field] = dataArray[index];
};
});
$scope.serverdata.push(value);
});
});
$scope.serverdata
现在看起来像
{
key1: 'val 10',
key2: 'val 11',
key3: 'val 12',
}
{
key1: 'val 20',
key2: 'val 21',
key3: 'val 22',
}
{
key1: 'val 30',
key2: 'val 31',
key3: 'val 32',
}

使用
拨打电话$http
.post(url + '/import-data', {
"data": $scope.serverdata
})
.then(function (res) {
console.log(res);
}, function (error) {
console.log("error : ", error);
})

试试这个:
_.each($scope.data, function(result, index) {
var dataArray = result.split(",");
$http
.post(url + '/import-data', {
"data": _.object( $scope.fields, dataArray)
})
.then(function (res) {
console.log(res);
}, function (error) {
console.log("error : ", error);
})
});
