元素已存在。当我尝试放置@browser.html时，它会显示整个页面的源代码。我的目标是只显示一个特定的HTML元素。我试过上面的代码行。我不明白错误是怎么说的。

试试这个，因为这是特定于元素的

@browser.find_element(:id, "street")

试一试

查找元素方法对于Watir是未定义的。另一种方法是@browser.element（：id，“street”）。但是我犯的错误还是一样的。你想做什么

将文本放入文本\u字段
？很难说你在问什么。我在问元素的具体页面来源。你在使用FF35吗？听起来像。如果是这样的话，它已经有了，所以你可能想降级到FF34@browser.text_字段（：id=>“foo”）.html
应返回特定元素的html，而@browser.text_字段（：id=>“foo”）.value应返回文本字段中的文本。目前Firefox 35的YMMV.execute_脚本已被破坏，只要WebDriver 2.45发布，修复程序就会准备就绪。实际上，您需要@browser.text_field（：id=>“foo”）.text来返回文本字段中的文本。如果标记中有value属性，value将返回该属性。FF35？那是火狐35版吗？对我正在用那个。但是我怎样才能把它降到FF34呢？
puts @browser.text_field(:id => "street").value if @browser.text_field(:id => "street").exists?
