关于常用的验证的一些收藏

以下是一些验证：usingNamespace("Biz.Common")["Validation"]={         textCount:function(field,counter,maxLimit)     {    var message = $(field).val();    if($(field).val().length>maxLimit)                $(field).val(message.substring(0,maxLimit))        //$(counter).text(maxLimit-field.value.length);         },       refreshValidator:function(img,input)       {           $(img).attr('src',$(img).attr('src') + "&r="+Math.random());           $(input).focus();       },    isUrl:function(s){var strRegex =                              /^((http(s)?|ftp|telnet|news|rtsp|mms):\/\/)?(((\w(\-*\w)*\.)+[a-zA-Z]{2,4})|(((1\d\d|2([0-4]\d|5[0-5])|[1-9]\d|\d).){3}(1\d\d|2([0-4]\d|5[0-5])|[1-9]\d|\d).?))(:\d{0,5})?(\/+.*)*$/;                            return strRegex.test(s);},    isDecimal:function(d){var pattern = /^(([1-9]\d{0,12})|0)(\.\d{1,2})?$/;return pattern.test(d);},   isEmail:function(s){var pattern =/^[\w-]+(\.[\w-]+)*@[\w-]+(\.[\w-]+)+$/;return pattern.test(s);},isLowEmail:function(s){var b,e;b=s.indexOf("@");e=s.indexOf(".");if(b<=0)return false;if(e<0 || e==(s.length-1)){return false;}return true;},clearNoNum:function(event,obj){         event = window.event||event;         if(event.keyCode == 37 | event.keyCode == 39){             return;         }         obj.value = obj.value.replace(/[^\d.]/g,"");         obj.value = obj.value.replace(/^\./g,"");         obj.value = obj.value.replace(/\.{2,}/g,".");         obj.value = obj.value.replace(".","$#$").replace(/\./g,"").replace("$#$",".");     },     checkNum:function(obj){         obj.value = obj.value.replace(/\.$/g,"");     },isInteger:function(value){    var integerReg = new RegExp(/^\d+$/);    return integerReg.test(value);},isValidateReg:function(value){    var validateReg =/^([A-Za-z0-9\s\-\_\~\!\@\#\$\%\^\&\*\(\)\|\<\>\?\:\;\"\'\.\[\]\{\}\,\+\`\/\\\=]){6,20}$/;   if(validateReg.test(value))   {    return true;   }   return false;},isDate:function(strValue){   var objRegExp = /^\d{4}(\-|\/|\.)\d{1,2}\1\d{1,2}$/         if(!objRegExp.test(strValue))         return false;         else{         var arrayDate = strValue.split(RegExp.$1);         var intDay = parseInt(arrayDate[2],10);         var intYear = parseInt(arrayDate[0],10);         var intMonth = parseInt(arrayDate[1],10);         if(intMonth > 12 || intMonth < 1) {         return false;         }         var arrayLookup = { '1' : 31,'3' : 31, '4' : 30,'5' : 31,'6' : 30,'7' : 31,         '8' : 31,'9' : 30,'10' : 31,'11' : 30,'12' : 31}         if(arrayLookup[parseInt(arrayDate[1])] != null) {         if(intDay <= arrayLookup[parseInt(arrayDate[1])] && intDay != 0)         return true;         }         if (intMonth-2 ==0) {         var booLeapYear = (intYear % 4 == 0 && (intYear % 100 != 0 || intYear % 400 == 0));         if( ((booLeapYear && intDay <= 29) || (!booLeapYear && intDay <=28)) && intDay !=0)         return true;         }         }         return false; },isZip:function(value){    var validateReg=/^[0-9]{6}$/;   return validateReg.test(value);},checkSpecialChar:function(value){          var validateReg =/([~!@#$%^&*\/\\,.\(\)]){6,16}$/;   return validateReg.test(value);    },    CheckSpecialString :function(value)    {       var validateReg =/[\u0000-\u0008\u000B\u000C\u000E-\u001F\uD800-\uDFFF\uFFFE\uFFFF]/;   return validateReg.test(value);    },    isTel:function(s){            var patrn=/^\d{3,4}-\d{7,8}(-\d{3,4})?$/            if (!patrn.exec(s)) return false           return true       },      isMobile:function(value)    {          var validateReg=/^1\d{10}$/;   return validateReg.test(value);    },    getLength :function(value)    {       return value.replace(/[^\x00-\xff]/g,"**").length;    },    isLicence:function(value){var validateReg=/^[A-Za-z]{10}[0-9]{10}$/;return validateReg.test(value);},isPersonalCard:function(value){var validateReg=/(^\d{15}$)|(^\d{17}(\d|[A-Za-z]{1})$)/;return validateReg.test(value);},isOrganizationCodeCard:function(value){var validateReg=/^[A-Za-z0-9]{9}$/;return validateReg.test(value);},isBankAccount:function(value){var validateReg=/^[1-9]{1}[0-9]*$/;return validateReg.test(value);},    MaxLength:function(field,maxlimit)    {        var j = field.value.replace(/[^\x00-\xff]/g,"**").length;         var tempString=field.value;        var tt="";        if(j > maxlimit)       {        for(var i=0;i<maxlimit;i++)        {         if(tt.replace(/[^\x00-\xff]/g,"**").length < maxlimit)          tt = tempString.substr(0,i+1);         else           break;         }         if(tt.replace(/[^\x00-\xff]/g,"**").length > maxlimit)         {         tt=tt.substr(0,tt.length-1);          field.value = tt;         }       else       {        field.value = tt;        }     }  } };

以下是一些对字符串是否为空，以及去空格的处理：

usingNamespace("Web.Utils")["String"] = {    IsNullOrEmpty: function(v) {        return !(typeof (v) === "string" && v.length != 0);    },    Trim: function(v) {     if (!$String.IsNullOrEmpty(v)) {            return v.replace(/^\s+|\s+$/g, "")        }    },    TrimStart: function(v, c) {        if ($String.IsNullOrEmpty(c)) {            c = "\\s";        };        var re = new RegExp("^" + c + "*", "ig");        return v.replace(re, "");    },    TrimEnd: function(v, c) {        if ($String.IsNullOrEmpty(c)) {            c = "\\s";        };        var re = new RegExp(c + "*$", "ig");        return v.replace(re, "");    },    Camel: function(str) {        return str.toLowerCase().replace(/\-([a-z])/g, function(m, c) { return "-" + c.toUpperCase() })    },    Repeat: function(str, times) {        for (var i = 0, a = new Array(times); i < times; i++)            a[i] = str;        return a.join();    },    IsEqual: function(str1, str2) {        if (str1 == str2)            return true;        else            return false;    },    IsNotEqual: function(str1, str2) {        if (str1 == str2)            return false;        else            return true;    },    MaxLengthKeyUp: function(obj, len) {        var value = $(obj).val();        if (value.length > len) {            $(obj).val(value.substring(0, len));        }    },    MaxLengthKeyDown: function(obj, len) {        if ($(obj).val().length > len) { return false; }        return true;    }};
