How does one of the objects contained in the DOM object get out?

  node.js, question

Be shaped like

<li>Pretty row 1
 <div class="obj_data">[object Object]   </div>
 Want to take out obj, but can't get it?

In this case, you can’t get it out. You should first use print format instead of directly outputting the object in what language you use at the back end.
