在ionic中向下滚动列表时选中此复选框

Question

我有一个离子选择器，并在ionChange上打开一个带有复选框的警报。可以选择多个选项。 这是我的代码：

MERGE (artifact :ARTIFACT :V_1 :LAKE :EXISTING { blobUid: 'existingArtifact'})
ON CREATE SET
  artifact.uid = 'abc',
  artifact.createdAt = 123,
  artifact.createdBy = 'snekki'
WITH artifact

OPTIONAL MATCH (maybeFileData :FILE_DATA :V_1 :LAKE) -[:DESCRIBES]-> (artifact)
WITH
  artifact,
  maybeFileData,

  CASE
    WHEN maybeFileData IS null THEN [true]
    ELSE []
  END AS isFileDataNull,

  CASE
    WHEN maybeFileData IS null THEN []
    ELSE [true]
  END AS isFileDataNonNull

WITH
  CASE
    WHEN
      maybeFileData IS NOT null
      AND maybeFileData.filename = 'abc.txt'
      AND maybeFileData.checksum = '1a2b3c'
      AND maybeFileData.fileSize = 12345
    THEN
       maybeFileData
    ELSE
      null
  END AS resultForNonNull,
  artifact, maybeFileData, isFileDataNull

UNWIND isFileDataNull AS x
  CREATE (fileData :FILE_DATA :V_1 :LAKE {
    uid: 'xyz',
    createdAt: 123,
    createdBy: 'georgio',
    filename: 'abc.txt',
    checksum: '1a2b3c',
    fileSize: 12345
  }) -[:DESCRIBES]-> (artifact)
WITH artifact, maybeFileData, fileData AS resultForNull, resultForNonNull

RETURN
  CASE
    WHEN maybeFileData IS null THEN [resultForNonNull, artifact]
    ELSE [resultForNull, artifact]
  END AS result

问题在于当用户快速向下滚动选项时，即使滚动触摸也可以选中复选框。 有什么办法吗 谢谢
