如何通过Selenium和Python将文本发送到搜索字段 [英] How to send text to the search field through Selenium and Python

问题描述

我正在尝试使用Python中的Selenium将参数传递给HTML代码中的搜索文本:

I am trying to pass arguments to a search text in a HTML code using Selenium in Python:

我正在处理以下HTML代码:

I am working on the following HTML code:

</form><form class="search-box-inner">
    <div class="input-container">
        <input type="text" class="typeahead search-box-input left" autocomplete="off" placeholder="Search ratings, research, analysts, and more..." maxlength="900"></div>
</form>

该代码没有ID或名称.它仅按类具有元素.

The code does not have id or name. It has elements by class only.

我尝试了以下

self.driver.find_elements_by_class_name('search-box-inner').send_keys("HSBC Bank plc")  

但是出现以下错误:

AttributeError: 'list' object has no attribute 'send_keys'

然后，我尝试使用以下代码获取列表的第一个元素并发送密钥:

Then I tried to fetch first element of the list and send keys by using the following code:

self.driver.find_elements_by_class_name('search-box-inner')[0].send_keys("HSBC Bank plc")

我收到以下错误:

"selenium.common.exceptions.WebDriverException: Message: unknown error: cannot focus element"

我也尝试过上述两种方法，用于预先输入左侧搜索框输入"类.它会引发相同的错误.以下是我用于此的代码:

I have tried both the above methods for "typeahead search-box-input left" class as well. it throws the same error. following is the code I used for this:

self.driver.find_elements_by_xpath("//*[@class='typeahead search-box-input left']").send_keys("HSBC Bank plc")

我再次遇到以下错误:

AttributeError: 'list' object has no attribute 'send_keys'

然后，我尝试使用以下代码获取列表的第一个元素:

Then I tried to fetch the first element of the list with the following code:

self.driver.find_elements_by_xpath("//*[@class='typeahead search-box-input left']").[0].send_keys("HSBC Bank plc")  

我再次遇到以下错误:

selenium.common.exceptions.ElementNotVisibleException: Message:
element not interactable

我还尝试了以下方法:

element = wait.until(Ec.visibility_of_element_located((By.XPATH, "//*[@placeholder='Search ratings, research, analysts, and more...']")))

但是无法将参数/键发送到搜索栏.
任何建议都会非常有帮助.

But could not sent the argument/keys to the search bar.
Any suggestions will be really helpful.

推荐答案

find_elements_by_xpath返回Web元素的列表，因此这就是您不能直接在其上使用send_keys方法的原因.如果需要在元素上使用send_keys，则需要使用find_element_by_xpath或find_elements_by_xpath("xpathExpression")[0].

find_elements_by_xpath returns a list of webelement so that is the reason you cant use the send_keys method directly on that. You need to use find_element_by_xpath or find_elements_by_xpath("xpathExpression")[0] if you need to use send_keys on the element.

请尝试以下建议解决您的问题:

Please try the below suggestions to solve your problem:

1. 尝试使用xpath self.driver.find_element_by_xpath("//div[@class='input-container']")而不是您正在使用的xpath.

1. Try the xpath self.driver.find_element_by_xpath("//div[@class='input-container']") instead of the xpath you are using.

即使在使用上述xpath后如果得到ElementNotVisibleException，也请检查该元素是否在iframe中，如果是，则切换到iframe，然后在该元素上使用send_keys.

Even after using the above xpath if you get ElementNotVisibleException then please check if the element is in iframe, if yes, then switch to the iframe and then use send_keys on the element.

要切换到iframe，您可以使用:driver.switch_to.frame(driver.find_element_by_tag_name('iframe'))，然后使用提到的xpath在元素上使用send_keys，如果要切换回默认内容，可以使用driver.switch_to.default_content()

To switch to iframe you can use: driver.switch_to.frame(driver.find_element_by_tag_name('iframe')) and then send_keys on the element using the mentioned xpath and if you want to switch back to the default content, you can use driver.switch_to.default_content()
