MOOTOOLS JS - Clear input field onClick onFocus on click focus active


 / Published in: JavaScript
 

  1. // 201004291250 - Mootools clear input on focus, return default value if no data entered
  2. // FROM: Clear text field with mootools on focus. - MooTools Users | Google Groups http://bit.ly/cHPev3
  3.  
  4. /*
  5. I've got this snippet that will clear the value on focus and if the value of
  6. the focus is '' it will put the default value again in the input. You will
  7. need the default value to be on an attribute of the input, like alt or
  8. anyother (if you don't bother about validation).
