Jsp defines the value

<script type="application/javascript"> var dataList= "${data.dataList}"; </script>

In the connected js choose

 $(document).ready(function(){ console.log(dataList); }

In the console as a result

 [ru.test.TestClass@253d1594, ru.test.TestClass@59cfed2c, ru.test.TestClass@525614c0, ru.test.TestClass@47381287]

What am I doing wrong? I need the values ​​of the object list. How to process the list of values?

  • Possibly override the toString method of your TestClass - JVic

In the current implementation, you call the default method toString of the dataList object, which, apparently, is an object of the ArrayList class.

In order to fulfill your plans, you need:

  • either create a class from ArrayList, and override the toString method
  • or convert the dataList to a string in the form of JSON (or to the js array type), and only then transfer it to jsp
  • either bypass the dataList right in jsp
