如何禁用链接？你要增加的是一门课吗？属性？
# Check for a link that has a "disabled" class:
page.should have_css("a.my_link.disabled")
page.should have_xpath("//a[@class='disabled']")
# Check for a link that has a "disabled" attribute:
page.should have_css("a.my_link[disabled]")
page.should have_xpath("//a[@class='disabled' and @disabled='disabled']")
# Check that the element is visible
find("a.my_link").should be_visible
find(:xpath, "//a[@class='disabled']").should be_visible
The actual xpath selectors may be incorrect. I don't use xpath often!
