我正在使用以下代码，以便通过右键单击（在 Selenium 上下文菜单中）显示菜单。
# encoding: utf-8
require 'watir-webdriver'
b = Watir::Browser.new
b.goto 'localhost:8080/swbadmin'
b.text_field(:name => 'wb_username').set 'admin'
b.text_field(:name => 'wb_password').set 'webbuilder'
b.button(:text => 'Login').click
a = b.div(:class => 'dijitTreeNodeContainer').div(:class => 'dijitTreeIsRoot').div(:class => 'dijitTreeRow').span(:class => 'dijitTreeContent')
c= a.span(:text => 'tst')
c.right_click
问题是 dijitTreeNodeContainer 是由道场制作的。所以我必须等到它加载所有信息，我尝试使用 Watir::wait.until{ span(:text => 'tst').visible ?} 但它不起作用。使用此代码没有行
c= a.span(:text => 'tst')
并且使用 c.click，我可以单击默认的 TreeContent，但是当我尝试使用右键单击或双击时，它会引发异常（..cannot preform native interaction...）这是 html 代码
