使用XPath或ID或其他任何通过硒和Python脚本找不到按钮

Question

我很新的使用Python，但是这似乎是一个非常简单的脚本我想写。我已经能够登录到网站正常，但要获得下一步我想点击一个按钮，上面写着“市场快车”。

我能看到的XPath（// [@ ID = “MarketExpress”]），以及按钮的ID（MarketExpress）。当我运行模块I收到此错误：“无法定位元件：// [@ ID =” MarketExpress“]”

我已经使用Firefox插件“的XPath取景器”，以确保我有正确的代码，甚至双重检查中的XPath。

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.keys import Keys
from selenium.webdriver import ActionChains

usernameStr = '***'
passwordStr = '***'

driver = webdriver.Firefox()
driver.get(('https://www.myurl.com'))

username = driver.find_element_by_id('USERID')
username.send_keys(usernameStr)
password = WebDriverWait(driver, 10).until(
    EC.presence_of_element_located((By.ID, 'currentPassword')))
password.send_keys(passwordStr)
nextButton = driver.find_element_by_id('submit-button')
nextButton.click()

password = driver.find_element_by_name('currentPassword')
password.send_keys(passwordStr)
nextButton = driver.find_element_by_name('Submit')
nextButton.click()

marketExpress = driver.find_element_by_xpath('//*[@id="MarketExpress"]').click();

我已经尝试了很多不同的东西，但不能拿到剧本点击此按钮，我希望得到任何帮助！

下面是HTML，其中按钮：

<input class="crtordbtn" type="button" value="Market Express" `id="MarketExpress" onclick="parent.location.href='/OMAPX?userId=051220665&amp;clientId=8&amp;UserType=null&amp;BuyerCookie=null';">`

下面是我相信按钮是表：

 <div id="sidebar-left" height="50%" style="margin-right:10px">
<div id="bar" style="margin-right:-3px"><h1>Select To Order</h1></div>

<div style="width:100%; height:50%; border-left:1px solid #cccccc;border-right:1px solid #cccccc;border-bottom:1px solid #cccccc;margin-bottom:10px;"> 

 <table width="235px" cellspacing="0" cellpadding="0" border="0">

 <!--  <tr align="center">
 <td style="padding: 5px 40px 0px 40px;">


 <input class="crtordbtn" type="button" value="eSysco Express" id="esyscoExpress" onClick="parent.location.href='http://flex2.esysco.net';" />
 </td>
 </tr>
 <tr >
 <td style="padding: 5px 40px 0px 40px;text-align:left">
 <p>Our latest order management application with improved performance and enhanced usability</p>
</td>
</tr>-->

<tbody><tr align="center">

    <td style="padding: 5px 40px 0px 40px;">

            <input class="crtordbtn" type="button" value="Market Express" id="MarketExpress" onclick="parent.location.href='/OMAPX?userId=051220665&amp;clientId=8&amp;UserType=null&amp;BuyerCookie=null';">


    </td></tr>
    <tr>
    <td style="padding: 5px 40px 0px 40px;text-align:left">
        <p>Our latest order management application with improved performance and enhanced usability</p>
    </td></tr>
    <tr>



</tr>

</tbody></table>
 </div>

Answer 1

所需的元件是一个动态元素，以便以找到具有诱导WebDriverWait为元素是可点击的元件并且可以使用下列的解决方案：

• 使用CSS_SELECTOR： WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.crtordbtn#MarketExpress[onclick*='OMAPX?userId']"))).click()
• 使用XPATH： WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='crtordbtn' and @id='MarketExpress'][contains(@onclick, 'OMAPX?userId')]"))).click()
• 注意：您要添加以下的进口：

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC

Answer 2

尝试this.It应该工作。

driver.find_element_by_xpath("//table[@id='esyscoExpress']/tbody/tr//input[@class='crtordbtn']").click()

Answer 3

这或许是用id会工作。希望能帮助到你

driver.find_element_by_id("MarketExpress").click()
