我正在使用ngCSV,loDash和PapaParse导出和导入一个嵌套数组的对象数组。
数组如下所示:
[
{
arrival:"15.34.59",
cancelled:"",
comments:[{message: "test", commenttime: "15.34", $$hashKey: "object:552"}]
date:"27/09/2016"
},
{
arrival:"16.32.59",
cancelled:true,
comments:[]
date:"27/09/2016"
}
]
当我点击以下按钮时:
<button
ng-csv="commenttoJson(filteredRecords)"
csv-header="['date', 'comments', 'arrival', 'cancelled']"
filename="{{ createCsvFilename(dates) }}">
Download
</button>
它会触发此功能并下载文件:
$scope.commenttoJson = function(filteredRecords){
return _.map(filteredRecords, function(record){
return _.extend({}, record, {comments: JSON.stringify(record.comments)});
});
}
生成的文件如下所示:
date,comments,arrival,cancelled
27/09/2016,"[{""message"":""testing"",""commenttime"":""14.52"",""$$hashKey"":""object:50""}]",14.52.29,,
27/09/2016,[],,TRUE
然后我继续使用这些函数导入它:
$scope.onFileSelect = function ($files) {
Papa.parse($files[0], {
header: true,
skipEmptyLines: true,
complete: function(results, $files,err) {
if (err) {
console.log('err ', err);
}
$scope.parseddata = results.data;
}
});
};
$scope.importData = function () {
$indexedDB.openStore('records', function(store){
store.insert($scope.parseddata).then(function(e){
store.getAll().then(function(record) {
$scope.recordlist = record;
console.log($scope.recordlist);
$('.import-data').modal('hide');
$scope.deleted = false;
});
});
});
};
问题在于它完全导入所有内容,除了评论之外,现在看起来如下所示,并且显然不会被前端正确阅读:
[
{
arrival:"15.34.59",
cancelled:"",
comments:"[{"message":"test","commenttime":"15.34","$$hashKey":"object:552"}]"
date:"27/09/2016"
}, (...)
显然在这个过程中我遗漏了一些东西,因为所有额外的引号都会弄乱我的代码。
关于如何解决这个问题的任何想法?
$scope.onFileSelect = function ($files) {
Papa.parse($files[0], {
header: true,
skipEmptyLines: true,
complete: function(results, $files,err) {
if (err) {
console.log('err ', err);
}
$scope.filteredRecordsToImport = _.map(results.data, function(item){
return _.extend(item, {comments: item.comments ? JSON.parse(item.comments) : []});
});
console.log($scope.filteredRecordsToImport);
}
});
};
显然我不得不重新解析JSON以反转stringify并摆脱数组中的额外引号!
答案 0 :(得分:1)

return _.extend(item, {comments: item.comments ? JSON.parse(item.comments) : []});
});
console.log($scope.filteredRecordsToImport);
