為所有的textbox控件增加onblur事件

function addOnblurEvent()

{

         var newopen = function(control)   

        {   

          return function()   

          {   

            CheckInput(control);//該函數(shù)為外部定義的一個(gè)執(zhí)行函數(shù)；   

          }   

        }   

        var inputElements=document.getElementsByTagName("input");

        for( var i in inputElements)

        {

            if( inputElements[i].type=="text")

            {  

                var txtObject=null;

//                var txtValue=null;

                         txtObject=inputElements[i];

//                          txtValue=document.all(txtObject.id).value;

                        if (window.attachEvent)

                        { 

                            //支持 IE

                            txtObject.attachEvent("onblur",newopen(txtObject)); 

                        }

                        else

                        {

                            //支持 FF

                            txtObject.addEventListener("onblur",newopen(txtObject)); 

                         }

            }

        }

}
