title: jquery input-validation (number characters and decimal places)
body: <p>I have several javascript functions to validate the input data in textbox, so it will limit the user to type into the textbox a range of numbers (eg. from 0 to 500) an x amount of decimals (eg. 1 or 2 or 3 ....).</p>
  
  <p>I am having some issues with the javascript functions because they are three separate functions and the alerts get a bit mixed up.</p>
  
  <p>I was wondering if there is a jquery function that will make it neat, effective and simple.</p>
  
  <p>Thanks.</p>
