Question

我正在尝试使用Selenium WebDriver和Ruby实现拖放功能。为了实现我的目标：

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :firefox

driver.get "myurl"

source = driver.find_element(:id, '19026240')
target = driver.find_element(:xpath, "//div[@id='rootLabelChildren']/div/div")

driver.action.drag_and_drop(source, target).perform

这不会导致任何错误，如无法定位元素，元素未附加到DOM等。但这会导致超时错误：

手动，拖放工作正常。什么可能是超时错误的原因？

Firefox版本：21 Selenium WebDriver：2.33.0

HTML code：

目标

<div id="rootLabelChildren" class="children">
<div class="label " labelid="74ce292d65844af7b4e480782d8e9b38" labelname="0106">
<div class="labelName terminal" draggable="true">0106</div>
<div class="children"> </div>
</div>

对于来源

<table class="dataGridHeader">
<div class="dataGridScrollbarContainer scrollable" style="">
<div class="dataGridContents" style="min-height: 12880px;">
<table class="buffer" style="margin-top: 0px;">
<tbody>
<tr id="19026240" class="selected" draggable="true">

根据CHANGELOG

Selenium WebDriver：2.33.0 不支持 Firefox版本：21 。因此将其降级为 Firefox版本：19 或 Firefox版本：20 。

这将处理错误：rescue in rbuf_fill。

要拖放元素，请尝试以下操作：

require 'selenium-webdriver'

driver = Selenium::WebDriver.for :firefox
driver.get "myurl"
source = driver.find_element(:css, 'tr#19026240')
target = driver.find_element(:css, 'div#rootLabelChildren>div>div')
driver.action.drag_and_drop(source, target).perform

对于拖放功能，我得到了一个很好的链接HTML5 Drag and Drop with Selenium Webdriver。它会帮助你。

drag_and_drop因超时错误而失败
