经典ASP-尝试在另一个字符串变量中搜索一个字符串. (替代InStr函数) [英] Classic ASP - Trying to search a string in another string variable. (Alternative to InStr function)

问题描述

在下面的代码currentregion = 'BC'和Regions = 'ABC'中.

我正在尝试在Regions中找到currentregion，通常因为if条件为false，它应该会按else.

I am trying to find the currentregion in the Regions and normally it should hit else as the if condition is false.

但是它返回true，因为InStr搜索部分字符串而不是字符串vs字符串.因此，BC是ABC的一部分，因此进入if循环.

But it returns true as InStr searches part of the string not string vs string. So BC being part of ABC it enters the if loop.

Classic ASP中有一个函数，我可以将字符串与字符串进行比较，但不能像InStr函数那样将字符串作为字符串的一部分.

Is there a function in Classic ASP that I can compare a string to string but not part of the string like InStr function.

RegionSQL = "SELECT * FROM Regions Where Auth <= " & Session("U_Auth") & ";"                
Set rsRegion=Server.CreateObject("recordset")
rsRegion.Open RegionSQL,TheDB

If NOT rsRegion.EOF And NOT rsRegion.BOF Then
    rsRegion.MoveFirst
    While Not rsRegion.Eof 
        'Grab Current Region
        currentregion = rsRegion("RegionCodeShort")   

        If InStr(Regions,currentregion) > 0 Then
            checked = "checked"
        Else
            checked = ""
        End If

推荐答案

拆分首先将字符串放入数组，然后遍历并比较每个元素

Split the string into an array first, then loop through and compare each element
