[jira] Commented: (WICKET-995) getMarkupId generates ID which contains special characters which should be escaped or replaced

Ryan Holmes commented on WICKET-995:
------------------------------------

The period is a valid character in an HTML ID. See http://www.w3.org/TR/html4/types.html#type-id.

To refer to an HTML ID with a period in a CSS selector context, the period must be escaped. If JQuery does not support this, it is a JQuery bug and should be filed with them.

The automatic transformation of certain characters by a framework is exactly the kind of magic behavior that confuses users and therefore I think the recommended "fix" is a bad idea.

Furthermore, since no actual bug has been reported here, this issue should probably be resolved as invalid.

> This is about how wicket generates dynamically markupID.
> I have, for instance, the following markup component:
> <input wicket:id="quantity.noOfUnits" />
> The generated markupId for this component looks like the following: quantity.noOfUnits1232 .
> I suggest to escape any css valid specifiers from the generated markupId, by replacing them with something else (for instance '_' character).
> The problem appear when I am trying to identify the component by it's id using some js library (like jQuery) and as a consequence the result of this query: $("#quantity.noOfUnits1232") is invalid.
