form input prefill clearer and reset

Published in: JavaScript 

Plain TextExpand 
  1. // form input prefill clear on focus, and reset on blur (if empty)
  2.  
  3. function prefillClear(field) {
  4.  
  5. if (field.defaultValue==field.value) {field.value = '';}
  6.  
  7. else if (field.value == '') {field.value = field.defaultValue;}
  8.  
  9. }
  10.  
  11. // usage
  12.  
  13. <input type="text" name="input1" value="Enter your data" onfocus="prefillClear(this);" onblur="prefillClear(this);" />
  14.  
  15. // suggest using some further javascript to parse all input fields and apply these functions on domReady. This would save having to put the function calls inline.
