Detailed Description#

Warning

The QJSValueIterator constructor takes a QJSValue as argument. After construction, the iterator is located at the very beginning of the sequence of properties. Here’s how to iterate over all the properties of a QJSValue :

object = QJSValue()
...
it = QJSValueIterator(object)
while it.hasNext():
    it.next()
    print(it.name(), ": ", it.value().toString())

The next() advances the iterator. The name() and value() functions return the name and value of the last item that was jumped over.

Note that QJSValueIterator only iterates over the QJSValue ‘s own properties; i.e. it does not follow the prototype chain. You can use a loop like this to follow the prototype chain:

obj = ... # the object to iterate over
while obj.isObject():
    it = QJSValueIterator(obj)
    while it.hasNext():
        it.next()
        print(it.name())

    obj = obj.prototype()
