asp.net 1.1中分组验证的实现

根据验证控件的TabIndex这个几乎没有用的属性来分组

页面Javascript脚本:

 

    <script language="javascript">
    function hideOldValidatorDisplay() 
    {
        var i;
        for (i = 0; i < Page_Validators.length; i++) 
        {
            var val = Page_Validators[i];
            if (typeof(val.display) == "string") 
            {    
                if (val.display == "None") 
                {
                    return;
                }
            }
            if (val.display == "Dynamic") 
            {
                val.style.display = "none";
                return;
            }
            val.style.visibility = "hidden";
        }
    }
    var oldPage_Validators;
    function selectForValidator(tabIndex)
    {
        if(typeof(oldPage_Validators) == "undefined")
        {
            oldPage_Validators = Page_Validators;
        }
        result = new Array();
        for(i = 0;i < oldPage_Validators.length; i++)
        {
            if(oldPage_Validators[i].tabIndex == tabIndex)
            {
                result[result.length] = oldPage_Validators[i];
            }
        }
        hideOldValidatorDisplay();
        Page_Validators = result;
    }
    </script>

        {
            if(!Page.IsPostBack)
            {
                //验证TabIndex为15的验证控件
                this.lbtnSubmit.Attributes["onclick"]="selectForValidator(15);";
                //验证未设TabIndex，即TabIndex=0的验证控件
                this.btnSubmit.Attributes["onclick"]="selectForValidator(0);";
            }
        }
        protected bool ValidateGroup(Int16 validatorTabIndex)
        {
            bool isInputValid = true;

                }
            }
