Form condition registry

[anonymous]

I would like to have a framework which can manage a forms state, useful in complex forms management. You provide a name a function or object that provides the condition and then based on the condition add handlers to success and failure. An example which would suite me would be the selection of a radio button hides some form elements and shows others, the more complex situ would be different elements of a drop down box would have a different effect on different parts of the form.

An example of how I was trying to tackle the hide/show was this:

function SetControls?(that){

var ControlArray? = byClass(that.target.id, byId('the_form'));

for(x = 0; x < ControlArray?.length; x++){

var ConrolToChange? = ControlArray?[x];

var ControlClassesArray? = KMI.common.getClassNameArray(ConrolToChange?);

if(!KMI.BasicInformation?.CheckControlInfluences?(ControlClassesArray?, that.target)){

if(ConrolToChange?.style.display == 'inline'){

ConrolToChange?.style.display = 'none';

}else if(ConrolToChange?.style.display == 'none'){

ConrolToChange?.style.display = 'inline';

}

if(ConrolToChange?.style.visible == 'hidden'){

ConrolToChange?.style.display = 'visible';

}else if(ConrolToChange?.style.display == 'visible'){

ConrolToChange?.style.display = 'hidden';

}

}

}

}

KMI.BasicInformation?.CheckControlInfluences? = function(ClassArray?, that){

var isInfluenced = false; KMI.common.Info('Method: KMI.BasicInformation?.CheckControlInfluences?'); try {

for(n = 0; n < ClassArray?.length; n++){

var OtherCBControl = byId(ClassArray?[n]); KMI.common.Info(OtherCBControl.id); if(OtherCBControl.checked && OtherCBControl.id != that.id){

return true;

}

} return false;

} catch(exc) {

KMI.common.Info(exc.message);

}

}

Using this, each of the elements that are hide/shown from the selection of a checkbox have the id of the checkbox in their class name. This only handles one dimensional form structure though and has no way of handling extra logic.

I will check into the IRC regularly if you want to pick my hed, I am on the list too :) I would like to provide input if possible as I have put a lot of thought into the ins and outs of this :)

Sounds like a good idea... any updates on this? (I'm guessing the reporter has long since forgotten this ticket as well...)

pushing out as no one has had time to work on this.

Should we keep this open?

Nathan, is there anything in here that is worth adding to your work on forms?

I think that this functionality might be covered by dojox.form.DropDownStack? or dojox.form.RadioStack?.

I'm going to close this - as it's an old bug, without much interest. Also, the dojox.form widgets I mentioned above perform this same sort of functionality (toggling parts of a form on and of, based on a dropdown/radio button)
