js验证模型自我实现的具体方法(2)

var userInfo = ValidateHelper.initInfo();
        if (userInfo == null) {
            return;
        }

$.ajax({
            type: "post",
            dataType: "text",
            url: "Ajax/Module.aspx",
            timeout: 30000,
            data: { UserName: userInfo.UserName, UserPwd: userInfo.UserPwd },
            success: function(data) {
                alert(data.toString());
            }
        });
    }

这边呢要是在提交数据的时候会调用validateStringValueIsEmpty方法，要是返回的是失败 是不会真的提交给服务器端得。
那上面的情况是一个最简单的处理不为空的情况，要是我们想验证是否是Email 是否是身份证号码，这些复杂的验证实现如下：

复制代码 代码如下:

var 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\-\_\~\!\@\#\$\%\^\&\*\(\)\|\<\>\?\:\;\"\'\.\[\]\{\}\,\+\`\/\\\=]){6,16}$/;
        if (validateReg.test(value)) {
            return true;
        }
        return false;
    },
    isDate: function(strValue) {
        var objRegExp = /^\d{4}(\-|\/|\.)\d{1,2}\1\d{1,2}$/
