Assigning Java variable to javascript variable.

Hi All,

I have a list of objects. I am getting that list in jsp using request object.I want to fetch object from java list object then get a value from that object and assign it to a javascript variable. Is it possible? I have tried following code but Its not working. Also If it is possible how much time it will take if list size is 1500?


<script type="text/javascript"> <% List<CustomObject> customList = (List<CustomObject>)request.getAttribute("customList"); CustomObject customObject=null; if(customList != null) {%> d = new dTree('d'); <% for (Iterator iterator = customList.iterator(); iterator.hasNext();) { customObject = (CustomObject)iterator.next(); %> var id_var = <%=customObject.getId()%>; var parentId_var = <%=customObject.getParentId()%>; var href_var =<%=customObject.getHref()%>; var class_var= <%=customObject.getClazz()%>; var label_var = <%=customObject.getLabel()%>; d.add(parseInt(id_var), parseInt(parentId_var),label_var,href_var,'','',class_var,'','',''); <% } %> document.write(d); <% } %> </script>

Pawan,

I have tried following code but Its not working

is useless and doesn't provide any clue to anybody here.

Check your HTML generated by the code ( View source of web browser) and see if you could figure it out.

Try this

<script type="text/javascript"> function jsFunc(b){ alert(b); } </script>

onclick='javascript:jsFunc("${'Hai'}")'

scriptlet in jsp is discourage . set the value into anyscope on servlet . and use EL to read that . Here i use String "Hai"
for example .

Hope this helps

What you are trying to do is possible but not recommended. As seetharaman has told you, try to use EL

When debugging servlet/jsp/javascript applications it is helpful to use a browser such as FireFox with plugins which let you see EXACTLY what the browser request is actually getting and the JavaScript structures being created.
