python - 如何在 selenium (Python) 中将密钥发送到没有 id 和/或名称的表单

问题描述

我正在从网站获取数据，每当我单击链接以获取电话号码时，都会打开一个模态表单以首先询问我的电话号码，然后向我显示电话号码。

我现在面临的挑战是，我想将键发送到输入字段，所以因为输入字段没有名称或 ID，我使用 xpath 找到了输入字段：

xxx = driver.find_element_by_xpath("//input[@placeholder='081xxxxxxxx']")

我打印了这个，它返回了一些硒对象，但是当我尝试发送如下键时：

xxx.send_keys('08100000000')

下面是一段 html 代码：

<div class="row">
<div class="medium-12 columns">
    <div class="guest-text">
        One step closer! <br />
        <span>Please provide your contact number to view business contact details</span>
    </div>

    <form action="" data-abide="ajax" novalidate="novalidate">
        <div id="txtUserPhoneNumber" ng-show="!isLoggedIn && collectUserPhone == ''" class="guest-no">
            <label>
                <div class="guest-label">Phone Number</div>
                <input type="text" placeholder="081xxxxxxxx" ng-model="UserPhoneNew" required data-invalid="" aria-invalid="true" maxlength="11">

            </label>
        </div>
    </form>
</div>

我试过了：

xxx = driver.find_element_by_xpath("//input[@placeholder='081xxxxxxxx']")
xxx.send_keys('08100000000')

dummy_number = driver.find_element_by_xpath("//div[contains(@class, 'modal small guest')]/div[contains(@class, 'guest-modal-wrapper')]//form[1]//input[1]")
dummy_number.send_keys('081000000')

我收到错误消息：

    RunAutomation.instantiatechrome()

欢迎您的意见。

解决方案

错误消息说该元素不可见。所以你必须明确地等到它变得可见。使用这里描述的 ExpectedCondition。

最后，您的代码可能如下所示（最多等待 120 秒）：

from selenium.webdriver.support import expected_conditions as EC

...

wait = WebDriverWait(driver, 120)
element = wait.until(EC.visibility_of_element_located((By.XPATH, "//input[@placeholder='081xxxxxxxx']")))
element.send_keys('08100000000')
