比较两个数组的值——经典的asp

本文介绍了比较两个数组的值——经典的asp的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

例如，如何比较两个数组的值以检查一个数组是否没有另一个数组的元素 -

How can I Compare values of two arrays to check if 1 array does not have an element of another array for example -

array1(0) = 85
array1(1) = 459
array1(2) = 90

array2(0) = 459
array2(1) = 90

我想返回第二个数组中不存在的值?我尝试使用双 for 循环，但对我来说效果不佳.

I want to return the values that are not present in the second array? I tried with double for loops but didn't work out to well for me.

推荐答案

Dim array1(3)
Dim array2(2)

array1(0) = 85
array1(1) = 459
array1(2) = 90

array2(0) = 459
array2(1) = 90

Dim i 'As Integer
Dim j 'As Integer
Dim isFound 'As Boolean

For i = 0 To UBound(array1) - 1
    isFound = False
    For j = 0 To UBound(array2) - 1
        If array1(i) = array2(j) Then
            isFound = True
        End If
    Next 'j
    If Not isFound Then
        Response.Write array1(i) & " not found<br />"
    End If
Next 'i
