[p]实现函数:[br]function ischarsinbag (s, bag)[br]{ [br]var i,c;[br]for (i = 0; i < s.length; i++)[br]{ [br]c = s.charat(i);//字符串s中的字符[br]if (bag.indexof(c) > -1) [br]return c;[br]}[br]return "";[br]}[br]检查函数:[br]function ischinese(s)[br]{[br]var errorchar;[br]var badchar = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz0123456789><,[]{}?/+=|\'"":;~!#$%()`";[br]errorchar = ischarsinbag( s, badchar)[br]if (errorchar != "" )[br]{[br]report=report+"请重新输入中文 ";[br]return false;[br]} [/p]
[p]return true;[br]}[br]就这么简单:)其实还输入日语,晕[/p]
