Bug? JQueryElement setProp not working with 'data-' attributes

[alwaysbusy]

There seems to be a problem with jQuery when using setProp() and attributes starting with 'data-' e.g. 'data-position'. I haven't been able to test it but I suspect the behaviour will be the same doing it in pure B4J.

This is used in one of my libraries (java):

JQueryElement j = page.ws.GetElementById(ID.toLowerCase());
j.SetProp("data-position", ToolTipPosition);

Behaviour:
The property is not set


I solved it now by creating a function like this:

Java library

public static void SetProperty(ABMPage page, String ID, String name, String value) {
     anywheresoftware.b4a.objects.collections.List Params = new anywheresoftware.b4a.objects.collections.List();
     Params.Initialize();
     Params.Add(ID);
     Params.Add(name);
     Params.Add(value);
     page.ws.RunFunction("SetProperty", Params);
   }

HTML

function SetProperty(id, name, value) {
     $('#' + id).attr(name, value);
}

This is not a bug. SetProp calls the jQuery prop method. You need to instead call the attr method.

You can use the RunMethod for this (with attr as the method value).

Could I make a suggestion jQueryElement gets two new methods SetAttr() and GetAttr() because it is easy to forget attributes with 'data-' in it do not work with SetProp() and GetProp(), while others like 'class' do?
