Changing Text to Uppercase or Lowercase

From SmartWiki
Jump to: navigation, search

You can change the case of the text entered in a custom field by writing this code in HTML Tag box in the custom field settings.

To convert entered text to Uppercase

onChange="javascript:this.value=this.value.toUpperCase();"

To convert entered text to lowercase

onChange="javascript:this.value=this.value.toLowerCase();"


The code gets executed as soon as the user enters a value and clicks anywhere outside the field (even without having to hit SAVE).


You can also use onBlur instead of onChange

onblur="this.value=this.value.toUpperCase()"
  • onBlur runs when the focus moves away from the current field
  • onChange runs when the content of the field has changed
