I have been working on enhancements to datacontroller. One of the nice things that I want to integrate is client side error detection to reduce roundtrips. It would be a variation on this.
http://www.alvinwang.com/j2/errchk.js The way it works is each field that you want to have checked will have an onblur event that calls a javascript. I will change the library to match the widget datatypes. The problems is that standard widgets have error fields but no ids so I can stuff the error messages into them class TextField(Widget): template = """ <div xmlns:py="http://purl.org/kid/ns#"; py:strip="True"> <input type="text" name="${widget.name}" value="${widget_value}" id="${widget.name}" class="text_field" py:attrs="widget.attrs"/> <span class="field_error" ID="inf_${widget.name}" py:if="widget_error">${str(widget_error)}</span> </div> """ If each widget had the ID="inf_${widget.name}" attribute added to it, I am pretty sure that the widget attr clause could be used to pass in the javascript call. I would also need onsubmit="return validateOnSubmit()" on the form tag. I think I can pass that into the form widget. I guess the question would be if I should create my own set of widgets or should this be included in the standard widgets. Thanks Alvin
