I have done it like this, and it is working fine:
class MySelect2DropDown(HTML):
def __init__(self, values = None, width = 300, myid = None):
if myid == None:
myid = get_random_id()
self.myid = myid
html = '<select id="%s" style="width:%dpx">' % (myid, width)
for value in values:
html += '<option value="%s">%s</option>' % (value, values[value
])
html += '</select>'
HTML.__init__ (self, html)
def final_setup(self):
myjs = 'parent.jQuery("#%s").select2();' % (self.myid)
Logger("MySelect2DropDown", "Now calling JS: %s" % (myjs))
JS(""" eval(@{{myjs}}) """)
