title: jQuery: what is the best way to restrict "number"-only input for textboxes? (allow decimal points)
body: <p>What is the best way to restrict "number"-only input for textboxes?</p>
  
  <p>I am looking for something that allows decimal points.</p>
  
  <p>I see a lot of examples. But have yet to decide which one to use.</p>
  
  <p><strong>Update from Praveen Jeganathan</strong></p>
  
  <p>No more plugins, jQuery has implemented its own <code>jQuery.isNumeric()</code> added in v1.7.
