Hi ,

I am validating using javascript where two dropdown has the same value it should through the error. If sel1 and sel 2 has the value 0 it should through error otherwise not. If both are 1 or 2 it should not through error the JS function for this which I am using is

<script type="text/javascript" >
    function check_val(id1,id2) {
     var first_val = document.getElementById(id1).value;
     var sec_val = document.getElementById(id2).value;
     if ( first_val == 0 && sec_val == 0) {
     alert("Sorry please Select Another Choice");
     }   
    }
    </script>

and HTML
<select name="sel1" id="sel1" onchange="check_val('sel2', 'sel1')" >
            <option value="">Select</option>
            <option value="0" >Option 0</option>
            <option value="1" >Option 1</option>
            <option value="2" >Option 2</option>
            <option value="3" >Option 3 </option>
            <option value="4" >Option 4</option>
            <option value="5" >Option 5</option>
            <option value="6" >Option 6</option>
            <option value="7" selected="selected">Option 7</option>
          </select>

<select name="sel2" id="sel2" onchange="check_val('sel2', 'sel1')" >
            <option value="">Select</option>
            <option value="0" >Option 0</option>
            <option value="1" >Option 1</option>
            <option value="2" >Option 2</option>
            <option value="3" >Option 3 </option>
            <option value="4" >Option 4</option>
            <option value="5" >Option 5</option>
            <option value="6" >Option 6</option>
            <option value="7" selected="selected">Option 7</option>
          </select>

If this is work along with jquery.validate.js means it will be very helpful.

Thanks in advance
