left() 函数是 VBScript 的函数,VBScript 将1个汉字看作1个字符,因此用 left()不能得到正确的字符长度。
我自己编写了如下3个函数,用来取代 len()、left()、right(),希望能解决您的问题。
'--------------------------------------------------------
'Name: lenX
'Argument: uStr
'Return:
'Description: 返回字符串的长度,1个中文字符长度为2
'--------------------------------------------------------
function lenX(byval uStr)
dim theLen,x,testuStr
theLen = 0
for x = 1 to len(uStr)
testuStr = mid(uStr,x,1)
if asc(testuStr) < 0 then
theLen = theLen + 2
else
theLen = theLen + 1
end if
next
lenX = theLen
end function
'--------------------------------------------------------
'Name: leftX
'Argument: uStr 待处理的字符串
' uLen 要截取的长度
'Return:
'Description: 返回指定长度的字符串,1个中文字符长度为2
'--------------------------------------------------------
function leftX(byval uStr,byval uLen)
dim i,j,uTestStr,theStr
leftX = ""
j = 0
for i = 1 to len(uStr)
uTestStr= mid(uStr,i,1)
theStr = theStr & uTestStr
if asc(uTestStr) < 0 then
j = j + 2
else
j = j + 1
end if
if j >= uLen then exit for
next
leftX = theStr
end function
'--------------------------------------------------------
'Name: rightX
'Argument: uStr 待处理的字符串
' uLen 要截取的长度
'Return:
'Description: 返回指定长度的字符串,1个中文字符长度为2
'--------------------------------------------------------
function rightX(byval uStr,byval uLen)
dim i,j,uTestStr
rightX = ""
j = 0
for i = len(uStr) to 1 step -1
uTestStr = mid(uStr,i,1)
rightX = rightX & uTestStr
if asc(uTestStr) < 0 then
j = j + 2
else
j = j + 1
end if
