页面上弹出的对话框若是基于iframe，需要进行switch_to_frame操作，若是div形式，则处理更简单
操作有：打开对话框、关闭对话框、操作对话框中的元素
用到的HTML文档
<html> <head> <meta http-equiv="content-type" content="text/html;charset=utf-8" /> <title>modal</title> <script type="text/javascript" async="" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.min.css" rel="stylesheet" /> <script type="text/javascript"> $(document).ready(function(){ $(‘#click‘).click(function(){ $(this).parent().find(‘p‘).text(‘try watir-webdriver right now!‘); }); }); </script> </head> <body> <h3>modal</h3> <div class="row-fluid"> <div class="span6"> <!-- Button to trigger modal --> <a href="#myModal" role="button" class="btn btn-primary" data-toggle="modal" id="show_modal">Click</a> <!-- Modal --> <div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button> <h3 id="myModalLabel">Modal header</h3> </div> <div class="modal-body"> <p>watir-webdriver is better than slenium-webdriver</p> <a href="#" id="click">click me</a> </div> <div class="modal-footer"> <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button> <button class="btn btn-primary">Save changes</button> </div> </div> </div> </div> </body> <script src="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js"></script> </html>
代码
from selenium import webdriver
from selenium.webdriver.support.ui import ui
import time
import os
dr=webdriver.Firefox()
file_path=‘file:///‘+os.path.abspath(‘modal.html‘)
dr.get(file_path)
time.sleep(2)
dr.find_element_by_id(‘show_modal‘).click() #打开对话框
wait=ui.WebDriverWait(dr,10)
wait.until(lambda dr: dr.find_element_by_id(‘myModal‘).is_displayed()) #myModal是点击按钮引发的下拉列表
#点击对话框中的链接，由于对话框中的元素被蒙版遮挡，直接点击会报错，因此用js模拟click
link=dr.find_element_by_id(‘myModal‘).find_element_by_id(‘click‘)
dr.execute_script(‘$(arguments[0]).click()‘,link) #对link元素执行js脚本
time.sleep(2)
buttons=dr.find_element_by_class_name(‘modal-footer‘).find_elements_by_tag_name(‘button‘)
buttons[0].click() #关闭对话框
dr.quit()
