我不清楚您的问题，但您想在下拉列表中进行验证. >

I didn''t get your question clearly, but you want validation on drop down list right.. just go through this..

<select id="selctionlist" name="Answer to:">
   <option>1</option>
   <option>2</option>
   <option>3</option>
   <option>4</option>
   </select>
   <input type="text" /><input type="checkbox" name="c" /><br />
    <input type="text" /><input type="checkbox" name="c" /><br />
     <input type="text" /><input type="checkbox" name="c" /><br />
      <input type="text" /><input type="checkbox" name="c" /><br />
      <input type="button" onclick="validate()" /></select>

function validate()
        {

            var i = selctionlist.selectedIndex;
            if (c[i].checked == false)
            alert("Please check box" +(i+1));
            
            
       }
