代碼如下:
//字符處理;
//去左右空格;
function trim(s){
return rtrim(ltrim(s));
}
//去左空格;
function ltrim(s){
return s.replace( /^/s*/, "");
}
//去右空格;
function rtrim(s){
return s.replace( //s*$/, "");
}
//驗證信息;
//空字符值;
function isEmpty(s){
s = trim(s);
return s.length == 0;
}
//Email;
function isEmail(s){
s = trim(s);
var p = /^[_/.0-9a-z-]+@([0-9a-z][0-9a-z-]+/.){1,4}[a-z]{2,3}$/i;
return p.test(s);
}
//數字;
function isNumber(s){
return !isNaN(s);
}
//顏色值;
function isColor(s){
s = trim(s);
if (s.length !=7) return false;
return s.search(//#[a-fA-F0-9]{6}/) != -1;
}
//手機號碼;
function isMobile(s){
s = trim(s);
var p = /13/d{9}/;
return p.test(s);
}
//身份證;
function isCard(s){
s = trim(s);
var p = /^/d{15}(/d{2}[xX0-9])?$/;
return p.test(s);
}
//URL;
function isURL(s){
s = trim(s).toLowerCase();
var p = /^http:////[A-Za-z0-9]+/.[A-Za-z0-9]+[//=/?%/-&_~`@[/]/':+!]*([^<>/"/"])*$/;
return p.test(s);
}
//Phone;
function isPhone(s){
s = trim(s);
var p = /^((/(/d{3}/))|(/d{3}/-))?(/(0/d{2,3}/)|0/d{2,3}-)?[1-9]/d{6,7}$/;
return p.test(s);
}
//Zip;
function isZip(s){
s = trim(s);
var p = /^[1-9]/d{5}$/;
return p.test(s);
}
//Double;
function isDouble(s){
s = trim(s);
var p = /^[-/+]?/d+(/./d+)?$/;
return p.test(s);
}
//Integer;
function isInteger(s){
s = trim(s);
var p = /^[-/+]?/d+$/;
return p.test(s);
}
//English;
function isEnglish(s){

var p = /^[A-Za-z]+$/;
return p.test(s);
}
//中文;
function isChinese(s){
s = trim(s);
var p = /^[/u0391-/uFFE5]+$/;
return p.test(s);
}
//雙字節
function isDoubleChar(s){
var p = /^[^/x00-/xff]+$/;
return p.test(s);
}
//含有中文字符
function hasChineseChar(s){
var p = /[^/x00-/xff]/;
return p.test(s);
}
function hasAccountChar(s){
var p = /^[a-zA-Z0-9][a-zA-Z0-9_-]{0,15}$/;
return p.test(s);
}
function limitLen(s,Min,Max){
s=trim(s);
if(s=="") return false;
if((s.length<Min)||(s.length>Max))
return false;
else
return true;
}
