我正在使用JavaScript并在JavaScript函数内部添加新行,我想在创建行时向其添加属性和类名:
Future<String> _uploadImage(File file, int number,{String extension = 'jpg'}) async {
String result;
if (result == null) {
// generating file name
String fileName =
"$number$extension\_${DateTime.now().millisecondsSinceEpoch}.$extension";
AwsS3 awsS3 = AwsS3(
awsFolderPath: awsFolderPath,
file: selectedFile,
fileNameWithExt: fileName,
poolId: poolId,
region: usEast1,
bucketName: bucketName);
setState(() => isFileUploading = true);
displayUploadDialog(awsS3);
try {
try {
result = await awsS3.uploadFile;
debugPrint("Result :'$result'.");
} on PlatformException {
debugPrint("Result :'$result'.");
}
} on PlatformException catch (e) {
debugPrint("Failed :'${e.message}'.");
}
}
Navigator.of(context).pop();
return result;
}
上面您可以看到我将如何更新已有的属性,但是如何首先创建它们?
更新: 我首先需要为每一行创建classNames,因为稍后我需要通过类名查找标签。那么在创建行时如何给他们提供类名?

要将隐藏的数据信息添加到行中,可以使用data()
函数:
var rowNode = myTable.row
.add([results.location_id, location_name.value,
location_streetname.value, add_loc_hotline_phone])
.data({city: location_city.value, streetname: location_streetname.value})
.draw().node();
要添加类,您可以使用createdCell
回调:
$('#container').dataTable( {
// ...
"columnDefs": [ {
"targets": 0, // First column
"createdCell": function (td, cellData, rowData, row, col) {
td.classList.add(`column-id`);
}
} ]
} );
