在 VBScript 中搜索字符串以验证是否包含字符 [英] Search a string in VBScript to verify if contains a character

问题描述

我想看看一个字符串是否包含一个点.

I am trying to see if a string contains a dot.

Set Root_Currency = Root_TaxDataSummary.SlvObject("Currency")   
curr_val = InStr(Root_Currency,".")
If curr_val.exist Then

     pass
else
     fail

我的处理方式有什么问题吗?

Is there anything wrong with the way I am going about this?

推荐答案

InStr 返回一个整数，表示可以在字符串中找到搜索文本的位置.

InStr returns an integer representing the position the searched text can be found in the string.

curr_val.exist 将不起作用，因为整数类型没有 exist 方法.相反:

curr_val.exist won't work because the integer type doesn't have an exist method. Instead:

If curr_val > 0 Then

或者(如果这是该变量的唯一用途):

Or (if this is the only use of that variable):

If InStr(Root_Currency,".") > 0 Then

最后，因为 0 在 VBScript 中被视为 False，所以您不需要包含相等性.要么找到角色的位置，要么返回 0/false:

Lastly, because 0 is treated as False in VBScript, you don't need to include the equality. Either a position is found for the character or you get back a 0/false:

If InStr(Root_Currency,".") Then
