Never mind, I just made a constructor instead:
def js_default_text(default_txt):
js_clear_default = "if (this.value=='%s') this.value=''" %
default_txt
js_restore_default = "if (this.value=='') this.value='%s'"
% default_txt
return dict(
default=default_txt,
attrs=dict(
onFocus=js_clear_default,
onBlur=js_restore_default,
),
)
description = TextArea('description',
label='Work description',
rows=5, cols=80,
validator=UnicodeString(not_empty=True, strip=True),
**js_default_text(request_default_txt)
)
As long as the pieces of js I attach are fairly simple, it should be
fine for my needs.
