Prevent inputting of commas
Is it possible to prevent a content editor from inputting a comma into a text field? Like with
pattern="[a-zA-Z.-]"
on a regular text field.
I have the editors feed the options for a select field of a Perch Form through the backend.
Chances are high, they will input a comma, which will split the options in the wrong place.
Could you replace the comma if it exists using the
replaceattribute?Sounds good.
Unfortunately it doesn't seem to work. Here's my code:
When I enter "Mielke, N." into the text input in the Perch backend, the comma is interpreted as a divider and the Strings "Mielke" and "N." become separate options of the select field.
When I replace something else than the comma, e.g.
it works perfectly.
Ah, the
replaceattribute is comma delimited too. So that's no good.Escaping the comma with a backslash doesn't seem to do the trick either.
Any other ideas?
(Love the possibilities of
replace, though. Thanks for that hint.)Another suggestion would be to add some JavaScript as a UI plugin and check the field that way.
I'll look into that.
Thanks, Drew.
