Asp.net中验证控件扩展，使被验证框高亮

//Rewrite function ValidatorUpdateIsValid in WebUIValidation.js    
function ValidatorUpdateIsValid() {
    var i;
    var item;
    var index=-1;
    var canPass=true;
    var j=0;
    var bannerAD = new Array();
       
    for (i = 0; i < Page_Validators.length; i++) {
        if (!Page_Validators[i].isvalid) {
        //alert(Page_Validators[i].id+'-------a');
         item = document.getElementById(Page_Validators[i].controltovalidate);
         //item.style.borderColor="red";
         bannerAD[j]=item;
         //alert(bannerAD[j]);
         j++;
         //index=i;
         //canPass=false;
            Page_IsValid = false;
            //return;
        }
        else
        {
     //alert(Page_Validators[i].id+'------b');
            item = document.getElementById(Page_Validators[i].controltovalidate);
            item.style.borderColor="#ababab";
            //Page_IsValid = true;
        }
   }
   for( var t=0;t<bannerAD.length;t++)
   {
        //alert(bannerAD[t]);
        bannerAD[t].style.borderColor="red";
   }
   
   for (i = Page_Validators.length-1; i >=0 ; i--) {
        if (!Page_Validators[i].isvalid) {       
         index=i;       
         canPass=false;
        }     
   }
   if(index>=0)
   {
     item = document.getElementById(Page_Validators[index].controltovalidate);
     item.focus();
   }
     if(!canPass)
         return;
   Page_IsValid = true;
}

使用方法：

将上面的代码复制到任何一个使用验证控件的页面，此函数将会覆盖WebUIValidation里的同名函数，达到背景变色的目的

环境：asp.net 1.1，ie(很遗憾，firefox在asp.net1.1环境下，验证控件的客户端验证不会起作用)


ServerSide Code:

public static void SetControl(System.Web.UI.UserControl objUserControl)
                        {
                                    System.Web.UI.WebControls.BaseValidator validator=null;
                                    object controtovalidator=null;
                                    System.Web.UI.WebControls.WebControl wc=null;
                                    foreach( IValidator validator in Page.Validators[0] )
                                    {
                                 
                                          if(!validator.IsValid)
                                          {                                                                       
                                               wc.Attributes.Add("style","border-color:red");
                                           }
                                           else
                                           {
                                                wc.Attributes.Add("style","border-color:");
                                       }
                                    }                       
                        }
 
 
Code example:
 
static public void onRegisterValidation(Registration objRegistration)
                        {
                                    if(objRegistration.Page.IsValid)
                                    {
                                                …
                                    }
                                    else
                                    {                                   
                                                SetControl(objRegistration.InnerRegistrationInstance);
                                                
                                    }
                        
                        }
