Selenium Webdriver找不到单击按钮的元素

Question

I don't know the element used to click the button.

I tried to write like this:

driver.find_element_by_xpath('//*/input[@type="button"]').click()

Error message:

raise exception_class(message, screen, stacktrace) selenium.common.exceptions.ElementNotVisibleException: Message: element not visible

HTML:

<input type="button" name="ctl00$c3$g_6_f947_400a_aa18_59efd84584ae$ctl00$toolBarTbl$RightRptControls$ctl00$ctl00$diidIOSaveItem" value="Save" onclick="if (!PreSaveItem()) return false;if (SPClientForms.ClientFormManager.SubmitClientForm('WPQ2')) return false;WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$ctl33$g_69_f947_400a_aa18_59efd84584ae$ctl00$toolBarTbl$RightRptControls$ctl00$ctl00$diidIOSaveItem&quot;, &quot;&quot;, true, &quot;&quot;, &quot;&quot;, false, true))" id="ctl00_ctl33_g_696_f947_400a_aa18_59efd84584ae_ct0_toolBarTbl_RightRptControls_ctl00_ctl00_diidIOSaveItem" accesskey="O" class="ms-ButtonHeightWidth" target="_self">

Answer 1

Is the 'Save' word visible? if so you can try this:

driver.find_element_by_xpath("//*[contains(text(), 'Save')]").click()

Answer 2

Have you tried looking for the value?

driver.find_element_by_xpath('//*/input[@value="Save"]').click()

If this doesn't work it would be helpful if you could upload the HTML for the page you are testing or provide the URL.

Answer 3

Not sure why you are using //*/input rather using direct //input . Here is the solution.

driver.find_element_by_xpath("//input[@type='button' and @value='Save']").click()

Answer 4

The desired element is a dynamic element so to locate the element you have to induce WebDriverWait for the element to be clickable and you can use either of the following solutions:

• Using CSS_SELECTOR :

   WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.ms-ButtonHeightWidth[value='Save'][name$='SaveItem']"))).click() 

• Using XPATH :

   WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@class='ms-ButtonHeightWidth' and @value='Save'][contains(@name, 'SaveItem')]"))).click() 

• Note : You have to add the following imports :

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