简单问题：大家帮帮我，关于split取得值

[zhlj2003]

A=request("A")
response.write(A) 显示23,3,,,
txt_A=split(A,",")
但是 for i=1 to 5
txt_A(i)怎么有的不为空呢？？？后面那三个没有值啊
next

你应该知道""和null不是一个意思
上面虽然txt_A(3)..虽然是"" 但不是null

[ygghost]

for i=1 to 5

-->

for i=0 to 4

[jobine]

A=request("A")
txt_A=split(A,",")
for i=lbound(txt_A) to ubound(txt_A)
response.Write txt_A(i)
next

[tiandiqing]

这样你看看！
txt_A = split(A,", ")

如果是从form来的，","后要有个空格吧！

[iamsangster]

那你为什么要到5呢？

删不除呀

[ygghost]

是这样的：
-----------
split是从0开始
比如 23,3,
你输出txt_A(3)是会有错误发生的，
那个空格是 txt_A(2)
----------

[zhlj2003]

关键是那两个,,之间到底是null啊 还是"" 还是空格阿 我都晕了

[jacklinchen]

因为split是用来分割字符串的，然后放进数组的。
你可以用：
for each txt_A1 in txt_A
str=txt_A1
next

[ygghost]

如果还不明白：
就这样：
---------
A=request("A")
response.write(A) 显示23,3,,,
txt_A=split(A,",")
for i=0 to 4
response.write txt_A(i)
response.write "--"
next
---------------

你先对request("A")进行过滤嘛.
A=request("A")
for i=1 to len(A)
A=replace(A,",,",",")
next
注意有时候,,之间是有空格的

[超级大笨狼]

x="23,3,,,"
for i=o to ubound(split(x),",")
reponse.write split(x),",")(i)
next

[超级大笨狼]

<SCRIPT LANGUAGE=vbs>
x="23,3,,,"
for i=0 to ubound(split(x,","))
a=split(x,",")(i)
msgbox a & len(a)
next
</SCRIPT>

[超级大笨狼]

<SCRIPT LANGUAGE=vbs>
x="23,3,,,"
for each a in split(x,",")
msgbox a & len(a)
next
</SCRIPT>

各位似乎有点答非所问

[aspczlover]

下面能正确显示：

A=request("A")
response.write(A) ' 显示23,3,,,
txt_A=split(A,",")
'显示 23 3
for i=0 to ubound(txt_A)
response.write txt_A(i)
next
