Get widgetVar by Id
I have many cases in my apps where I needed to get the widgetVar object in Javascript by the component Id.
I have made this helpful function in order to achieve that goal .
function getWidgetVarById(id) {
for (var propertyName in PrimeFaces.widgets) {
if (PrimeFaces.widgets[propertyName].id === id) {
return PrimeFaces.widgets[propertyName];
}
}
}
Usage
getWidgetVarById('form:dialogId');
This will return the object, in the previous case a dialog widgetVar object is returned, to show it simply call show() right away.
getWidgetVarById('form:dialogId').show();
– Conclusion
All the widgetVars are stored in the PrimeFaces.widgets. namespace.
Iterating over that namespace and comparing the given Id with the object’s is the way to find your widgetVar.
Note: this equals to the expression #{p:widgetVar(‘form:dialogId’)} (Server-side evaluation)
