预期的一个[String，Regexp]，在页面对象中得到1：Fixnum（TypeError）

Question

我正在尝试查找图像，我正在使用带有图像exists?的if条件，然后执行删除操作。如果不是则添加。这样做我收到以下错误..

HTML：

<div class="xicGridViewport">
<table id="patetrnGrid-100228" class="xicGrid xicGridLoaded" cellspacing="0" cellpadding="0">
    <colgroup>
        <thead>
            <tbody>
                <tr id="id328" class=" xicGridRow0">
                    <td>
                        <td>
                            <td>
                                <td>
                                    <td>
                                        <td>
                                            <td style="text-align: center;">
                                                <td style="text-align: center;">
                                                    <a id="cellIconLink2a" href="#" onclick="var wcall=wicketSubmitFormById('form9', '?wicket:interface=:0:form:multiplePatternBuilderGroupBox:patternGroupbox:patetrnGrid:gridCheckGroup:xicGridContainer:xicGrid:rows:3:cells:8:cell:cellIconLink::IActivePageBehaviorListener:0:-1&wicket:ignoreIfNotActive=true', 'multiplePatternBuilderGroupBox:patternGroupbox:patetrnGrid:gridCheckGroup:xicGridContainer:xicGrid:rows:3:cells:8:cell:cellIconLink' ,null,null, function() {return Wicket.$$(this)&&Wicket.$$('form9')}.bind(this));;; return false;">
                                                        <img class="xicIcon xicIconLoaded xicIconDelete" xic:size="S" xic:icon="delete" src="/uit/xicola/2.3/img/spacer.png"> <!-- Here, where i am using if condition -->
                                                    </a>
                                                </td>
                </tr>
            </tbody>
            <tfoot>
</table>
</div>

代码：

pattern_builder_page.rb

        class BuilderPage
        include PageObject

        text_field(:area, name: /area/)
        select_list(:load_type, name: /loadType/)
        checkbox(:link_power, name: /linkPower/)
        image(:plus, css: ".xicIcon.xicIconLoaded.xicIconAdd")
        image(:delete_icon, css: ".xicIcon.xicIconLoaded.xicIconDelete")
        button(:delete, text: 'Delete')

        def create_pattern(category, place, destination)
            train_category_element.when_present
            self.train_category = category
            fac_place_element.when_present
            self.fac_place = place
            fac_destination_element.when_present
            self.fac_destination = destination
            wait_element.when_not_visible
            refresh_element.when_present
            refresh
            wait_element.when_not_visible
            if delete_icon_element.exists?
                delete
                yes_element.when_present.click
            end
    end
end

错误：

    expected one of [String, Regexp], got 1:Fixnum (TypeError)
      ./lib/pages/pattern_builder_page.rb:22:in `create_pattern'
      ./features/step_definitions/bulk_steps.rb:30:in `/^I select "(.*?)", "(.*?)" and "(.*?)" facility and submit$/'
      features\pattern_builder.feature:11:in `When I select "<category>",
 "<place>" and "<destination>" facility and submit'

Answer 1

根据异常消息，它来自Watir-Webdriver's ElementLocator：

VALID_WHATS = [String, Regexp]

def check_type(how, what)
  case how
  when :index
    unless what.kind_of?(Fixnum)
      raise TypeError, "expected Fixnum, got #{what.inspect}:#{what.class}"
    end
  else
    unless VALID_WHATS.any? { |t| what.kind_of? t }
      raise TypeError, "expected one of #{VALID_WHATS.inspect}, got #{what.inspect}:#{what.class}"
    end
  end
end

此方法显示定位器值只能是:index定位器的数字。

这意味着在您的某个定位器中，您传递的数字不是:index的定位器。例如，你有：

# An invalid accessor:
div(:field_name, :id => 1)

# Or what is ultimately called by Watir-Webdriver:
browser.div(:id => 1).text

根据评论，有一个xpath: 1定位器而不是index: 1定位器。
