Question

I have group of check-boxes and corresponding text-boxes with them. I can get each checkbox one by one, but how do I get the group of textboxes so I can validate them?

Here is my javascript code below:

function validate_orderform(proform) 
{           
var flag=0;
for (var i = 0; i < proform.chk.length; i++) {
   if (proform.chk[i].checked && proform.quant[i].value=="") {       
        flag=1;
   }
}

if(flag==1){
return false;
}

return true;
}

and my html code:

<td><input type="checkbox" id="chk1" name="chk"></td>
<td><input type="text" size="10" id="quant1" name="quant1"></td>...and so on

If name of textboxes are different then you can access all textboxes by

 var txtObjList = document.getElementsByTagName("input");
 for(var i=0; i < txtObjList.length; i++){
    if(txtObjList[i].getAttribute("type") == "text" && this.value != ""){
      // success for i+1 textbox
   }
 }

Or you can give common class name to all textboxes and then can access by

 var txtObjList = document.getElementsByClassName("classname");
 for(var i=0; i < txtObjList.length; i++){
    if(this.value != ""){
      // success for i+1 textbox
   }
 }

Remember by using javascript library such as jquery, prototype your work will be simpler.
