设计:

第一次下拉:

<select id="MainContent_drpVehicleType" style="width:175px;" name="ctl00$MainContent$drpVehicleType">
<option value="">- SELECT -</option>
<option value="1" title="AUTO">AUTO</option>
<option value="2" title="HD">HD</option>
<option value="3" title="MARINE">MARINE</option>
</select> 

第二次下拉:

<select id="MainContent_drpMake" style="width:175px;" name="ctl00$MainContent$drpVehicleType">
<option value="1" title="ACURA">ACURA</option>
<option value="2" title="ALFA ROMEO">ALFA ROMEO</option>
<option value="74" title="ALLIS CHALMERS LIFT TRUCK">ALLIS CHALMERS LIFT TRUCK</option>
<option value="75" title="ALLIS CHALMERS TRACTOR">ALLIS CHALMERS TRACTOR</option>
<option value="4" title="AMERICAN MOTORS">AMERICAN MOTORS</option
</select>

用于执行的代码:

b.select_list(:id, "MainContent_drpVehicleType").select("AUTO")

b.select_list(:id, "MainContent_drpMake").select("ACURA")

并尝试过

`b.select_list(:id, "MainContent_drpMake").wait_until_present.option(:text, 'ACURA')`

**我的问题是从第一次下拉菜单中选择"自动"并且无法从第二次下拉菜单中选择"ACURA"

执行时出错:
