i have table generate reports. need write javascript validation 1 report. unfortunately, javascript weak. have server side validation in place, need have javascript validation. page follows...

<tr> <form name="medicaidresidents" action="medicaid_residents.cfm"  method="post" id='f1' onsubmit="validateform(this.form);"> <td nowrap="nowrap"> medicaid residents </td> <td style="width: 5%;">      <table style="width: 5%;">     <tr>         <td style="width: 5%;"><br><br>         <input type="radio" name="choice" value='1' onclick="check_radio()";>all<br><br>          <input type="radio" name="choice" value='2' onclick="check_radio()";>states<br><br>         <input type="radio" name="choice" value='3' onclick="check_radio()";>communities         </td>         <td style="width: 5%;"> <select name="stateprompt1" multiple="multiple" size="10" id="t1">     <cfloop query="medicaid_states">         <option value="#medicaid_states.state_code#">#medicaid_states.state_code#</option>     </cfloop> </select>     </td>       <td style="width: 10%;">     <select name="houseprompt1" multiple="multiple" size="10" id="t2">     <cfloop query="medicaid_houses">         <option value="#medicaid_houses.ihouse_id#">#medicaid_houses.community# </option>     </cfloop> </select>     </td>     </tr>     </table>    </td> <td> <table style="width: 5%;">     <tr>         <td>              </td>     </tr>     <tr>         <td>      <input type="text" id="txtfromdate" name="dateprompt1">          </td>     </tr>     <tr>             <td>&nbsp;         </td>     </tr>     <tr>         <td>                 </td>     </tr>     <tr>         <td>         <input type="text" id="txttodate" name="dateprompt2">         </td>     </tr> </table> </td> <td> <input type="submit" name="go" value="go" style="font-size: 12; color: navy; height: 20px; width: 60px;"> </td> </form> </tr>

the javascript wrote is...

<script language="javascript"> function validateform(form){  if ( ( form.choice[0].checked == false ) && ( form.choice[1].checked == false ) && ( form.choice[2].checked == false ) )  { alert ( "please first select radiobutton" );  return false; } elseif ( ( form.choice[1].checked == true ) && ( document.getelementbyid("t1").value==""))  { alert ( "please select state" );  return false; } elseif ( ( form.choice[2].checked == true ) && ( document.getelementbyid("t2").value==""))  { alert ( "please select house" );  return false; } elseif ( ( document.dateprompt1.value =="") && ( document.dateprompt2.value==""))  { alert ( "please select 'from' , 'to' dates" );  return false; } } </script>

...but doesn't work. know javascript poorly writen. appreciate in getting work!

rather have series of else statements have if statements because stop return false, , green/passed path/action @ bottom.

function validateform(){      var = document.forms["medicaidresidents"]["choice"].value;    var b = document.forms["medicaidresidents"]["stateprompt1"].value;    var c = document.forms["medicaidresidents"]["houseprompt1"].value;          var d = document.forms["medicaidresidents"]["dateprompt1"].value;      var e = document.forms["medicaidresidents"]["dateprompt2"].value;          if (a == null || == "") {          alert("please first select radiobutton");      return false;    }            if (b == null || b == "") {          alert("please select state");      return false;    }           if (c == null || c == "") {          alert("please select house");      return false;    }          if (d == null || d == "" && e == null || e == "") {          alert("please select 'from' , 'to' dates");      return false;    }           return true;    }
<tr>  <form name="medicaidresidents" action="medicaid_residents.cfm"  method="post" id='f1' onsubmit="return validateform();">  <td nowrap="nowrap">  medicaid residents  </td>  <td style="width: 5%;">       <table style="width: 5%;">      <tr>          <td style="width: 5%;"><br><br>          <input type="radio" name="choice" value='1' onclick="check_radio()">all<br><br>           <input type="radio" name="choice" value='2' onclick="check_radio()">states<br><br>          <input type="radio" name="choice" value='3' onclick="check_radio()">communities          </td>          <td style="width: 5%;">  <select name="stateprompt1" multiple="multiple" size="10" id="t1">      <cfloop query="medicaid_states">          <option value="#medicaid_states.state_code#">#medicaid_states.state_code#</option>      </cfloop>  </select>      </td>        <td style="width: 10%;">      <select name="houseprompt1" multiple="multiple" size="10" id="t2">      <cfloop query="medicaid_houses">          <option value="#medicaid_houses.ihouse_id#">#medicaid_houses.community# </option>      </cfloop>  </select>      </td>      </tr>      </table>     </td>  <td>  <table style="width: 5%;">      <tr>          <td>                </td>      </tr>      <tr>          <td>        <input type="text" id="txtfromdate" name="dateprompt1">           </td>      </tr>      <tr>              <td>&nbsp;          </td>      </tr>      <tr>          <td>                   </td>      </tr>      <tr>          <td>          <input type="text" id="txttodate" name="dateprompt2">          </td>      </tr>  </table>  </td>  <td>  <input type="submit" name="go" value="go" style="font-size: 12; color: navy; height: 20px; width: 60px;">  </td>  </form>  </tr>
