When a text field should have Clear button?
I'm talking about little cross appearing inside text field after typing a text, espessially for search fields in desktop interfaces. But any considerations about general text fields on any platforms are also appreciated.
Some sites use clear button but others don't. I wonder what are pros and cons of both versions?
Example sites with clear button in search field:
- apple.com/search
- yahoo.com (on search results page)
- pinterest.com
- asos.com
- translate.google.com
And without:
- google.com
- youtube.com
- stackexchange.com
- github.com
- twitter.com
