Question

我有以下几行代码：

if @browser.text_field(:id => "street").exists?
      puts "street exist"
      puts @browser.text_field(:id => "street").html
    else
      puts "street does not exist"
    end

但是在运行这个之后，我有一个错误：

Run options: 

# Running tests:

street exist
E

该元素已存在。当我尝试puts @browser.html时，它会显示整个页面源。我的目标是只显示特定的HTML元素。我尝试了上面的代码行。我无法理解错误说的是什么。

Answer 1

尝试这个，因为这将特定于元素。

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

Answer 2

尝试

puts @browser.text_field(:id => "street").value if @browser.text_field(:id => "street").exists?

在Watir中显示HTML元素时出错
