asp(javascript)全角半角转换代码 dbc2sbc

asp与javascript 全角半角处理代码

asp全角半角转换函数
flag=-1时进行半角转全角
flag=0时进行半角全角互转
flag=1时进行全角转半角

<% Function DBC2SBC(Str, flag) Dim i, sStr If Len(Str)<= 0 Then Exit Function DBC2SBC = "" For i = 1 To Len(Str) sStr = Asc(Mid(Str, i, 1)) Select Case flag Case -1 If sStr>0 And sStr<= 125 Then DBC2SBC = DBC2SBC & Chr(Asc(Mid(Str, i, 1)) -23680) Else DBC2SBC = DBC2SBC & Mid(Str, i, 1) End If Case 0 If sStr>0 And sStr<= 125 Then DBC2SBC = DBC2SBC & Chr(Asc(Mid(Str, i, 1)) -23680) Else DBC2SBC = DBC2SBC & Chr(Asc(Mid(Str, i, 1)) + 23680) End If Case 1 If sStr<0 Or sStr>125 Then DBC2SBC = DBC2SBC & Chr(Asc(Mid(Str, i, 1)) + 23680) Else DBC2SBC = DBC2SBC & Mid(Str, i, 1) End If End Select Next End Function %>

javascript版 全角半角转换函数

function dbc2sbc(sStr){ var dbc2sbc = sStr; for (var i = 65281; i < 65375; i++) { var re = new RegExp(String.fromCharCode(i), "g"); var va = String.fromCharCode(i - 65248); dbc2sbc = dbc2sbc.replace(re, va); } dbc2sbc = dbc2sbc.replace(/　/g, ' '); return dbc2sbc; }

Javascript常用函数 sbc2dbc()

function sbc2dbc(sStr){ var sbc2dbc = sStr; for (var i = 33; i < 127; i++) { stringFromCharCode = String.fromCharCode(i); switch (stringFromCharCode) { case "(": case ")": case "*": case "+": case "/": case "\\": case "[": case "]": case "?": case "$": case ".": case "^": case "|": stringFromCharCode = '\\' + stringFromCharCode; default: break; } var re = new RegExp(stringFromCharCode, "g"); var va = String.fromCharCode(i + 65248); sbc2dbc = sbc2dbc.replace(re, va); } sbc2dbc = sbc2dbc.replace(/ /g, '　'); return sbc2dbc; }
