How to handle velocity variable in a multiselect custom field

[Alex]

Below is the code for a multiselect custom field:

I am having an issue displaying the selected values when I open the contentlet. If I see the velocityVarName valuable just printing it like this:

$context.get("${field.velocityVarName}") I can see the values all isted as (1,2,3,) ending with a comma.

I have tried using a loop:

 <option value="$con.identifier" 

               #foreach($id in $context.get("${field.velocityVarName}"))

                      #if($id == $con.identifier)selected#end

               #end>$con.name</option>

    

    #end

    </select>

But it does not display the selected values. Any suggestions are welcome!

Thank you,

Alex

<select multiple="multiple" size="scrollable" id="myMultiSelectField" onchange="updatemyMultiSelectField()" style="width: 200px;" ""="">

  

  #foreach($con in $dotcontent.pull("xxxx"))

 

    <option value="$con.indentifier" 

#if($context.get("${field.velocityVarName}") == $con.identifier)selected#end - I have to put this condition through a loop or something.

>$con.name</option>

   

    #end

    

    </select>

##field to store the value

<input type="hidden" id="myMultiSelectFieldId" value="">

    <script type="text/javascript">

        function updatemyMultiSelectField() {

            var myMultiSelectFieldValueList = "";

            var multiselect = $('myMultiSelectField');

            for(var i = 0; i < multiselect.options.length; i++) {

                if(multiselect.options[i].selected) {

                    myMultiSelectFieldValueList += multiselect.options[i].value + ",";

                }

            }

            $('myMultiSelectFieldId').value = myMultiSelectFieldValueList;

        }

        updatemyMultiSelectField();

    </script>

So I don't think you can get the field's velocity var name that way.  We always pass it as a variable set before the rest of the code for the field. 

Here's the code we use for this, we made it generic enough to be reusable since we have a lot of these:

Hope that helps!

Dear Chris:

Thank YOU so much!  This has sparkled so many insights about custom fields!

I modified it a bit and it works great!

I also have custom fields for single select field, but with JQuery.  Do you also have a sample of a single select field?

Regards,

Alex

For single Select we use the dojo FilteringSelect.  I am not sure if this still works or is deprecated at all in the latest version of dotCMS we are still on 4.1.1 and I haven't researched if this needs to be updated for 5.x.  I also included an older one we have using jQuery:
