Question

I wrote following piece of code to retrieve value of ‘recipientList’ in array abc but it is not working. Whenever I use

alert(abc[i]);

It returns ‘undefined’.
I need to use this abc[i]’s value as ‘options[]’ index in

document.getElementById(“recipients”).options[i].selected

What am I doing wrong?

var abc;

    <logic:greaterThan value="0" property="ConfigId" name="ConfigForm">
    <%

    ArrayList<RecipientDTO> recipientList= (ArrayList<RecipientDTO>) request.getAttribute("recipientTypesList");
    if (recipientList != null && recipientList.size() > 0) 
    {
            for (int i=0; i < recipientList.size(); i++) 
             {
                RecipientDTO recipientType = (RecipientDTO) recipientList.get(i);%>
                abc = [<%=recipientType.getRecipientType().toString()%>];
    <%  } %> 

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

        document.getElementById("recipients").options[i].selected = true; 

    }       

<% }
    %>
    </logic:greaterThan>

I also used

var abc = new Array();
abc[i] = "<%=recipientType.getRecipientType().toString()%>";

instead of

var abc;
abc = [<%=recipientType.getRecipientType().toString()%>];

but no use 🙁

Answer 1

try replacing var abc with var abc=new Array() and

abc = [<%=recipientType.getRecipientType().toString()%>];

with

abc[<%=i%>] = '<%=recipientType.getRecipientType().toString()%>';
