ruby - Selecting Options one by one Using watir-webdriver- -

b.select_list(:id, "maincontent_drpvehicletype").when_present.options.each |option|     option.select      b.select_list(:id, "maincontent_drpmake").when_present.options.each |option|         option.select          b.select_list(:id, "maincontent_drpmodel").when_present.options.each |option|             option.select              b.button(:id,"maincontent_imgbtnsearch").click         end     end end 

i'm having 3 dropdown each dropdown depends on previous values have select each option 1 one , click button . *while doing getting following error* element no longer attached dom (selenium::webdriver::error::staleelementreferenceerror)

also tried:

 b.driver.manage.timeouts.implicit_wait = 3 

assuming each option unique, try:

1. get last option in dependent list
2. make selection in current list
3. wait option in step 1 no longer appear

the following implements idea (though has not been tested since not have similar page test against):

b.select_list(:id, "maincontent_drpvehicletype").when_present.options.each |option|      #select vehicle type , wait last make option no longer appear     last_make_option = b.select_list(:id, "maincontent_drpmake").when_present.options.last     option.select     last_make_option.wait_while_present      b.select_list(:id, "maincontent_drpmake").when_present.options.each |option|          #select make , wait last model option no longer appear         last_model_option = b.select_list(:id, "maincontent_drpmodel").when_present.options.last         option.select         last_model_option.wait_while_present          b.select_list(:id, "maincontent_drpmodel").when_present.options.each |option|             option.select              b.button(:id,"maincontent_imgbtnsearch").click         end     end end 

note that:

• the code assumes last option of dependent list change. if not true, might need check against options of dependent list.
