如何获取Magento 2的系统配置设置

Question

我需要检索我在Magento插件的system.xml文件中设置的配置设置。

我已经在我的配置文件中设置了插件字段，并尝试在javscript文件中检索它们。这可能吗？

'function
Private Function GetNumbers(ByVal sumValue As Integer) As Integer()
    Dim seqNumbers As Integer() = {1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536}
    Dim seqNumbersInSum As New ArrayList

    'run through all numbers of the sequence.
    For seqIndex As Integer = UBound(seqNumbers) To 0 Step -1

        'don't use numbers of the sequence larger than the current sum value.
        If seqNumbers(seqIndex) > sumValue Then
            Continue For
        End If

        'subtract the current sequence number from sum value. Also add the used sequence number to the array list of used sequence numbers.
        sumValue -= seqNumbers(seqIndex)
        seqNumbersInSum.Add(seqNumbers(seqIndex))

        'in case the sum the result is 0 all sequence numbers are found.
        If sumValue = 0 Then
            Exit For
        End If
    Next

    'return the used sequence numbers.
    Return seqNumbersInSum.ToArray(GetType(Integer))
End Function

'usage
GetNumbers(162) ' {128, 32, 2}
GetNumbers(80)  ' {64, 16}
GetNumbers(64)  ' {64}

以下是我在JavaScript文件中尝试过的内容
