java - Spring MVC passing object to JSP and back -

i've controller class initialize method adding list of string model , view.

@requestmapping(value = "/my-site", method = requestmethod.get) public modelandview dostuff(httpservletrequest request){      modelandview modelandview = new modelandview("do-stuff");         ...      list<string> list = arrays.aslist("abc", "cba");     modelandview.addobject("mylist", list);     return modelandview; } 

question number 1: how access list in jsp file , use later in java script? trying like:

var mylist = []; <c:foreach var="entry" items="'${mylist}'">         mylist.push("${entry}");     </c:foreach> 

but reason inside mylist object instead of having 2 elements: "abc" , "cba" have "[abc", " cba]" contains symbols. why? doing wrong , how fix issue?

question number 2: have input button.

<input type="button" id="executebtn" name="executebtn" value="execute"> 

i want on button click fire event , send mylist object controller. please provide example method of js side , controller's method.

thanks lot!

why ${mylist} el expression quoted? rid of single quotes

var mylist = []; <c:foreach var="entry" items="${mylist}">     mylist.push("${entry}"); </c:foreach> 

i want on button click fire event , send mylist object controller

the mylist no longer exists in java form. exists serialized format in mylist var object. you'll need serialize format web application can understand: form object, comma separated list, json, xml, etc.
