如何在我的jsp中的javascript中访问来自服务器的Java列表

Question

Plz consider the scenario. I have a java class called Person as below:

Person
---------
Integer Id 
String name
String address

Now through my spring controller I pass a list of persons to my jsp page(neighbors.jsp) like shown below:

List<Persons> persons = new ArrayList<Person>();
.
.
.
return new ModelAndView("/neighbors").addObject("persons", persons);

Now the problem is here. I have the google maps api in javascript format embedded in neighbors.jsp to display the location of the person logged in. This works fine. Google maps also offer comparison of addresses. I want to display markers of addresses of other persons that are within 5 miles range of user's address. Each of the marker is a link to a page that is going to display that particular person's information.

Suppose I access each address in the following format, how do I call the javascript function?

<c:forEach items="${persons }" var="person">

       <!-- I want to pass each address ${person.address} to the javascript functions thats going to compare addresses --> 

</c:forEach>

Can someone help me out here on how to handle to scenario?

Two ways to do it:-

First way ... you can set the value as a hidden field that allows the javascript to access it:-

<c:forEach items="${persons}" var="person" varStatus="i">
   <input id="address${i.count}" type="hidden" value="${person.address}">
</c:forEach>

In your javascript:-

yourJavascriptFunction(document.getElementById("address1").value);

Second way ... use <script> tag in your <c:foreach> tag:-

<c:forEach items="${persons}" var="person" varStatus="i">
   <script>
       yourJavascriptFunction("${fn:replace(person.address, "\"", "\\\"")}");
       ...
   </script>
</c:forEach>
