完整的 VBScript 参考手册
Filter 函数返回一个基于 0 的数组,此数组包含以特定过滤条件为基础的字符串数组的子集。
注意:如果找不到与 value 参数相匹配的值,Filter 函数会返回一个空数组。
注意:如果参数 inputstrings 为 Null 或者不是一维数组,则会发生错误。
语法
Filter(inputstrings,value[,include[,compare]])
参数 | 描述 |

实例
实例 1
Filter:项目包含的 "S":
<script type="text/vbscript">
a=Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
b=Filter(a,"S")
for each x in b
document.write(x & "<br />")
next
</script>
a=Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
b=Filter(a,"S")
for each x in b
document.write(x & "<br />")
next
</script>
以上实例输出结果:
Sunday
Saturday

b=Filter(a,"S",False)
for each x in b
document.write(x & "<br />")
next
</script>
a=Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday")
b=Filter(a,"S",False)
