如何解析字符串呢？

[sword1028]

<script language="Javascript">
ss='1111111111111111'
怎样取得 一字符串的前9位?

[tripofdream]

try
<script language="Javascript">
var ss="1111111111111111";
var tmpstr=ss.substring(0,8);
alert(tmpstr);
</script>

[ar7_top]

如上

[lun2001]

<script language="vbscript">
dim ss,tmpstr
ss="1111111111111111"
tmpstr=left(ss,9)
msgboxt mpstr
</script>

[孟子E章]

ss.substr(0,8);

[jamex]

Javascript:
ss.substr(0,8);


vbscript
tmpstr=left(ss,9)

[tripofdream]

错了,应该是
ss.substr(0,9);
或
ss.substring(0,9);

用法:
strVariable.substring(start, end)
stringvar.substr(start [, length ])
第一种方法的参数有点不太好理解,MSDN上有这么一句:
The length of the substring is equal to the absolute value of the difference between start and end.
那么这个end的含义应该是start+length
