title: How can I get the title of a webpage given the url (an external url) using JQuery/JS
body: <p>I am a newbie, so excuse me if this is a silly question .. </p>
  
  <p>So what I was trying is to get the title of a URL using JQuery/JS. I dont want to load the content of the url and then parse  tags in it.</p>
  
  <p>Let me be more clear, I have a set of urls, say 20 for which I want to display the titles .. 
  the urls i am referring to are not the current urls, so I cant use js document.title ..</p>
  
  <p>so i want to do something of the form SOMEFUNC.title(URL) and get its title. Is there any such function?</p>
