vbs教程《字符串处理》

rem 拆分字符串
rem dim arr
rem arr = split("xiaohei,xiaobai,xiaoming", ",")
rem for each substr in arr
rem 	msgbox(substr)
rem next

rem 替换字符串
rem msgbox(replace("xiaohei,xiaobai,xiaoming", ",", "|"))

rem 获取子字符串
rem msgbox(mid("xiaohei,xiaobai,xiaoming", 1, 7))

rem 修剪左空格
rem msgbox(ltrim("     xiaohei"))
rem 修剪右空格
rem msgbox(rtrim("xiaohei     "))
rem 修剪左右空格
rem msgbox(trim("     xiaohei     "))

rem 查看子串位置
rem msgbox(instr("xiaohei,xiaobai,xiaobai,xiaoming", "xiaobai"))
rem msgbox(instr(10, "xiaohei,xiaobai,xiaobai,xiaoming", "xiaobai"))
rem msgbox(instr(30, "xiaohei,xiaobai,xiaobai,xiaoming", "xiaobai"))

rem 构造字符串
rem msgbox(string(5, "x"))

rem 构造字符串(空格组成)
rem msgbox("a" & space(5) & "b")

rem 左子串
rem msgbox(left("xiaohei,xiaobai,xiaoming", 7))
rem 右子串
rem msgbox(right("xiaohei,xiaobai,xiaoming", 8))

rem 字符串长度
rem msgbox(len("xiaohei"))

rem 前字母对应的ANSI字符代码
rem msgbox(asc("xiaohei"))

rem ANSI码 to 字符
rem msgbox(chr(120))

rem 转小写
rem msgbox(lcase("XIAOHEI"))

rem 转大写
rem msgbox(ucase("xiaohei"))

rem 连接字符串数组
rem dim arr(3)
rem arr(0) = "xiaohei"
rem arr(1) = "xiaobai"
rem arr(2) = "xiaoming"
rem msgbox(join(arr, ","))

rem 比较字符串(-1,0,1)
rem msgbox(strcomp("xiaohei", "xiaobai"))
rem msgbox(strcomp("xiaohei", "xiaohei"))
rem msgbox(strcomp("xiaobai", "xiaohei"))

rem 反转字符串
rem msgbox(strreverse("xiaohei"))
