将 hashmap 从 javascript 传递给 servlet [英] Passing hashmap from javascript to servlet

问题描述

I created a simplehashmap using the accepted solution in this question: How to create a simple map using JavaScript/JQuery

I however need to send this var to a servlet and retrieve them onto a Java HashMap. How do I do that.

The key is a string while the value is an array, say like:

`[1,'apple,orange, banana'],[2,'apple,peach, banana']` ...

I need the keys 1,2 and the array loaded onto a Java HashMap.

I tried to post it using jquery. where selectedrows is my map

$.post(url, { id: selectedrows });

解决方案

I creates a JSON string and then sent it via an ajax post to the servlet and build the HashMap there.
