本文介绍三种在QuickTest Professional (QTP)中使用不同方法实现列表框元素选择的自定义函数，包括利用正则表达式进行精确匹配及模糊匹配的方法1和方法2，以及采用VBS脚本InStr和Mid方法进行字符串匹配的选择方法3，并对比了它们的执行效率。

方法1：

Function RegexSelectQTP(Object, sPattern)

Dim oRegExp, arrAllItems, ix

'Create RegExp Object

Set oRegExp = New RegExp

oRegExp.IgnoreCase = False

oRegExp.Pattern = sPattern

'Split Object's all_items property

arrAllItems = Split(Object.GetROProperty("all items"), ";")

For ix = LBound(arrAllItems) To UBound(arrAllItems)

'If RegExp pattern matches list item, we're done!

If oRegExp.Test(arrAllItems(ix)) Then

Object.Select "#" & ix

Set oRegExp = Nothing

Exit Function

End If

'Select Item #1 by default

Object.Select "#0"

End Function

RegisterUserFunc "WebList", "RegexSelectQTP", "RegexSelectQTP"

使用的例子：

Browser("").Page("").WebList("").RegexSelectQTP "London - Heathrow" 'Select London-Heathrow

Browser("").Page("").WebList("").RegexSelectQTP "London - Heath.*" 'Select London-Heathrow

Browser("").Page("").WebList("").RegexSelectQTP "London - /D+" 'Select London-Heathrow

方法2：

Function RegexSelectDOM(Object, sPattern)

Dim oRegExp, oOptions, ix

'Create RegExp Object

Set oRegExp = New RegExp

oRegExp.IgnoreCase = False

oRegExp.Pattern = sPattern

'DOM options

Set oOptions = Object.Object.Options

For ix = 0 to oOptions.Length - 1

'If RegExp pattern matches list item, we're done!

If oRegExp.Test(oOptions(ix).Text) Then

Object.Select "#" & ix

Set oRegExp = Nothing

Exit Function

End If

'Select Item #1 by default

Object.Select "#0"

End Function

RegisterUserFunc "WebList", "RegexSelectDOM", "RegexSelectDOM"

使用的例子：

方法3：

这种方法并没有使用正则表达式，而是使用了VBS中的InStr和Mid方法

Public Function VBSSelect(Object, sString)

Dim sAllItems, varLocation, varEnd, varBeginning

'Retrieve Object's all_items property

sAllItems = Object.GetROProperty("all items")

'Verify if the supplied string is found in list's all_items property

varLocation = InStr(1, sAllItems, sString)

'If found:

If varLocation > 0 Then

varEnd = InStr(varLocation, sAllItems, ";")

If varEnd = 0 Then varEnd = Len(sAllItems) + 1

varBeginning = InStrRev(sAllItems, ";", varLocation)

Object.Select "" & Mid(sAllItems, varBeginning + 1, varEnd - varBeginning - 1)

Exit Function

End If

'Select Item #1 by default

Object.Select "#0"

End Function

RegisterUserFunc "WebList", "VBSSelect", "VBSSelect"

使用的例子：

Browser("").Page("").WebList("").VBSSelect "London - Heathrow" 'Select London-Heathrow

Browser("").Page("").WebList("").VBSSelect "London - Heath" 'Select London-Heathrow

Browser("").Page("").WebList("").VBSSelect "London - " 'Select London-Heathrow

三种方法的执行效率比较：

Run Mode	Normal	Fast
RegexSelectQTP	0.44 s	0.38 s
RegexSelectDOM	0.45 s	0.40 s
VBSSelect	0.39 s	0.35 s
