title: Jquery select item from popup and post back to parent
body: <p>In one of my projects, I have many different sections where I need to filter some data and select the required, for example - On newsletter page where I need to click a link to "add users" which opens up a popup window where I can search users by name, ID etc then check the checkboxes and click "Select". This adds their IDs (or maybe emails) in the hidden form on the Newsletter page. </p>
  
  <p>Similarly, I need to attach a file to newsletter then I click on an another link which opens up a popup with list of files which I can search and then finally select one. I have similar other requirements in other sections of the website which means I have to write similar type of code again and again. </p>
  
  <p>I won't mind duplicating code if it were to be used at one or two places. But I have more than 8-9 different sections where I have to select users, files, some other items etc so I was thinking if there was a generic plugin sort of tool which takes a url of the search page and returns the data back in a specific format to the parent opener window then I just include that code on each of these pages and just have to maintain one/two files only. </p>
  
  <p>How would you handle this sort of requirement? Is there any JQuery plugin available which does similar thing?</p>
