firefox上的Comparevalidator问题

这是ASP.NET 3.5及更早版本的客户端验证脚本中的错误。(该脚本在旧版本的Internet Explorer中正常工作,但在新的符合标准的浏览器中无法正常工作。)

Microsoft已修复了ASP.NET 4.0中的错误。

如果无法升级到ASP.NET 4.0,则可以从.NET 4.0附带的system.web.dll版本中导出webuivalidation.js资源,然后在页面的 PreRender 事件:

this.ClientScript.RegisterClientScriptInclude(
    typeof(System.Web.UI.WebControls.BaseValidator), "WebUIValidation.js",
    "url-to-the-4.0-WebUIValidation.js-script");

或者,您也可以覆盖马车 ValidatorConvert 通过将以下内容添加到 <script type="text/javascript"> 在页面上阻止:

function ValidatorConvert(op, dataType, val) {
    function GetFullYear(year) {
        var twoDigitCutoffYear = val.cutoffyear % 100;
        var cutoffYearCentury = val.cutoffyear - twoDigitCutoffYear;
        return ((year > twoDigitCutoffYear) ? (cutoffYearCentury - 100 + year) : (cutoffYearCentury + year));
    }
    var num, cleanInput, m, exp;
    if (dataType == "Integer") {
        exp = /^\s*[-\+]?\d+\s*$/;
        if (op.match(exp) == null)
            return null;
        num = parseInt(op, 10);
        return (isNaN(num) ? null : num);
    }
    else if(dataType == "Double") {
        exp = new RegExp("^\\s*([-\\+])?(\\d*)\\" + val.decimalchar + "?(\\d*)\\s*$");
        m = op.match(exp);
        if (m == null)
            return null;
        if (m[2].length == 0 && m[3].length == 0)
            return null;
        cleanInput = (m[1] != null ? m[1] : "") + (m[2].length>0 ? m[2] : "0") + (m[3].length>0 ? "." + m[3] : "");
        num = parseFloat(cleanInput);
        return (isNaN(num) ? null : num);
    }
    else if (dataType == "Currency") {
        var hasDigits = (val.digits > 0);
        var beginGroupSize, subsequentGroupSize;
        var groupSizeNum = parseInt(val.groupsize, 10);
        if (!isNaN(groupSizeNum) && groupSizeNum > 0) {
            beginGroupSize = "{1," + groupSizeNum + "}";
            subsequentGroupSize = "{" + groupSizeNum + "}";
        }
        else {
            beginGroupSize = subsequentGroupSize = "+";
        }
        exp = new RegExp("^\\s*([-\\+])?((\\d" + beginGroupSize + "(\\" + val.groupchar + "\\d" + subsequentGroupSize + ")+)|\\d*)"
                        + (hasDigits ? "\\" + val.decimalchar + "?(\\d{0," + val.digits + "})" : "")
                        + "\\s*$");
        m = op.match(exp);
        if (m == null)
            return null;
        if (m[2].length == 0 && hasDigits && m[5].length == 0)
            return null;
        cleanInput = (m[1] != null ? m[1] : "") + m[2].replace(new RegExp("(\\" + val.groupchar + ")", "g"), "") + ((hasDigits && m[5].length > 0) ? "." + m[5] : "");
        num = parseFloat(cleanInput);
        return (isNaN(num) ? null : num);
    }
    else if (dataType == "Date") {
        var yearFirstExp = new RegExp("^\\s*((\\d{4})|(\\d{2}))([-/]|\\. ?)(\\d{1,2})\\4(\\d{1,2})\\.?\\s*$");
        m = op.match(yearFirstExp);
        var day, month, year;
        if (m != null && (((typeof(m[2]) != "undefined") && (m[2].length == 4)) || val.dateorder == "ymd")) {
            day = m[6];
            month = m[5];
            year = (m[2].length == 4) ? m[2] : GetFullYear(parseInt(m[3], 10));
        }
        else {
            if (val.dateorder == "ymd"){
                return null;
            }
            var yearLastExp = new RegExp("^\\s*(\\d{1,2})([-/]|\\. ?)(\\d{1,2})(?:\\s|\\2)((\\d{4})|(\\d{2}))(?:\\s\u0433\\.|\\.)?\\s*$");
            m = op.match(yearLastExp);
            if (m == null) {
                return null;
            }
            if (val.dateorder == "mdy") {
                day = m[3];
                month = m[1];
            }
            else {
                day = m[1];
                month = m[3];
            }
            year = ((typeof(m[5]) != "undefined") && (m[5].length == 4)) ? m[5] : GetFullYear(parseInt(m[6], 10));
        }
        month -= 1;
        var date = new Date(year, month, day);
        if (year < 100) {
            date.setFullYear(year);
        }
        return (typeof(date) == "object" && year == date.getFullYear() && month == date.getMonth() && day == date.getDate()) ? date.valueOf() : null;
    }
    else {
        return op.toString();
    }
}

也许这对您有帮助(最后一篇文章,只需要datatype==“date”就行了),但我还没有测试过它: http://forums.asp.net/t/1358621.aspx

我的解决方案是创建一个继承自 BaseValidator 并覆盖 ControlPropertiesValid(), EvaluateIsValid() and OnPreRender(EventArgs e) . 如果你有其他想法,请开枪。

使用自定义验证器

Imports System.Globalization

  Private Sub CustomValidator1_ServerValidate(source As Object, args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
    Dim dateResult As Date
    If Date.TryParse(TextBox1.Text, CultureInfo.CreateSpecificCulture("zh-CN"), DateTimeStyles.None, dateResult) Then
        args.IsValid = True
    Else
        args.IsValid = False
    End If
End Sub

如果愿意的话,可以在JS的客户端使用等效的。
