<cfif IsDefined("form.MySelect")

I want to to pass the value users select from form.MySelect.

I use

<cfif IsDefined("form.MySelect")

</cfif>

it seems that ColdFusion server does not recognize it.

It works if I use text control.

I would like to know are there anyway to pass select value to ColdFsuion server to use <CFIF IsDefined>

If not, any suggestions or use hidden controls to set the value when user select a value from drop down box.

Your help and information is great appreciated,

Regards,

Iccsi,

    here is html code:

    <input name="cmdSubmit" type="submit" id="ccdSubmit" value="CONFIRMAR"/>

    here are my on submit code ,

    I still do not see the select even I comment event.preventDefault,

    jQuery("#cmdSubmit").click(function(event) {

              

     

      

      <!---  event.preventDefault();--->

       

       if (validate())

       {

      

        if (document.MyForm.MyNumber.value.length == 0)

         {

       document.MyForm.MyNumber.value =

          document.getElementById('MyForm').hidNumber.value;

         }

       

      

      

        jQuery.ajax({

         url:  "/Mycfm.cfc?method=MyMethod&MyNumber="   ("#txtMyNumber").val()),

      

      

         type: "POST",

         success: function(data)

         {

        

          alert( "My Number " + GetMyNumber(jQuery("#txtMyNumber").val()) +

          " for " + GetMyNumber(jQuery("#MyName").val()) +

           " Data update completed");

        

         

         }

        });

       }

       

      });


      <!---  event.preventDefault();--->

    Shouldn't that be /* event.preventDefault(); */ ? Anyway, from what I have read about event.preventDefault(), its purpose is to prevent the default click-action which, in this case, is form submission. So it is actually doing what it is designed to do! Why don't you comment it out?

    Coldfusion does recognize it. Use the value of the name attribute of the select field. For example,

    <cfif isDefined("form.mySelect")>

    form.mySelect: <cfoutput>#form.mySelect#</cfoutput>

    </cfif>

    <cfform action="#cgi.SCRIPT_NAME#">

    <cfselect name="mySelect">

    <option value="1">Yes</option>

    <option value="0">No</option>

    </cfselect>

    <cfinput name="sbmt" type="submit" value="send">

    </cfform>

    I use cfselect like following code,

    "hello" shows when I use <cfif not isDefined>, it does not show isDefined,

    Thanks again,

    Regards,

    <cfif isDefined("form.lstMylst")>

        hello

    </cfif>

    <td>
      <cfselect name="lstMylst" id="lstMylst">

             <cfoutput query="myQuery">
             <option value="#MyQuery.MyID#"
                <cfif (isDefined("form.MyID") AND form.MyID EQ myQuery.MyID)>selected="selected"</cfif>> #MyQuery.MyName# </option>

    The form is probably not submitted, is submitted to a different action page or has method type 'get'. To test, temporarily replace

    <cfif isDefined("form.lstMylst")>

        hello

    </cfif>

    with 

    <cfif isDefined("url.lstMylst")>

        hello

    </cfif>

    <cfdump var="#url#" label="URL scope">

    <cfdump var="#form#" label="Form scope">

    Do you see 'hello'? Are the URL or form variables dumped?
