Here you go.. this script is length but it very generic

<html>
<body>
<form>
<input type="text" name="txt1" value=""></br>
<input type="text" name="txt2" value=""></br>
<input type="text" name="txt3" value=""></br>
<input type="text" name="txt4" value=""></br>
<input type="text" name="txt5" value=""></br>
<input type="text" name="txt6" value=""></br>
<input type="text" name="txt7" value=""></br>
<input type="text" name="txt8" value=""></br>
<input type="button" name="btn" value="Validate" onClick="validate()"></br>
</form>
<script language="javascript">
function validate(){
 var arryInput=document.getElementsByTagName("input");
 var arryLength=arryInput.length;
 var aryAllowedVals=new Array("1","2","3","4","5","6","7","8");
 var blnAllowedVal =false;
 var errMsg="";

 for(var i=0;i<arryLength;i++){
   if(arryInput[i].type=="text"){
      for(var k=0;k<aryAllowedVals.length;k++){
            blnAllowedVal=false
             if(arryInput[i].value==aryAllowedVals[k]){
                aryAllowedVals.splice(k,1);
                blnAllowedVal=true;
                break;
              }
      }
      if(!blnAllowedVal){
        errMsg +="A Bad value or duplicate value was entered in :" + arryInput[i].name + "\n";        
      }
   }
  }

if(errMsg!=""){
      errMsg +="The following values were not entered:" + aryAllowedVals.toString()
      alert(errMsg);
      return false;
}
if(aryAllowedVals.length!=0){
  alert("The following values were not entered:" + aryAllowedVals.toString());
  return false;
