尝试访问 Select Input Python Splinter 时元素不可见

Question

我正在尝试使用 Python Splinter 在选择下拉列表中单击某些元素。

源代码（示例-原始选项值更多）为：

<div class="row form-group">
     <div class="col s12 m12 l6">
        <label>
        Zeitzone der Website
        </label>
        <div class="select-wrapper">
           <span class="caret">▼</span><input type="text" class="select-dropdown" readonly="true" data-activates="select-options-0388a2bc-2b5c-c534-8870-fc41b27e78c4" value="Wählen Sie eine Stadt">
           <ul id="select-options-0388a2bc-2b5c-c534-8870-fc41b27e78c4" class="dropdown-content select-dropdown ">
              <li class=""><span>Wählen Sie eine Stadt</span></li>
              <li class="optgroup-option "><span>Berlin</span></li>
           </ul>
           <select name="timezone" id="timezone-0" class="initialized">
              <option value="No timezone">Wählen Sie eine Stadt</option>
              <optgroup label="Europe">
                 <option value="Europe/Berlin">Berlin</option>
              </optgroup>
           </select>
        </div>
     </div>
  </div>

我想选择柏林。

我尝试了 browser.find_by_css / text 等，但该元素不可见，我成为异常。

Traceback (most recent call last):
  File "matomo.py", line 598, in <module>
    browser.find_option_by_text('Berlin').first.click()
  File "/usr/lib/python3.6/site-packages/splinter/driver/webdriver/__init__.py", line 562, in click

有任何想法、解决方法或提示吗？ :)

您可以尝试使用显式等待来等待它，

wait = WebDriverWait(driver, 10)
wait.until(EC.element_to_be_clickable(By.XPATH, "//span[contains(text(),'Berlin')]")).click()

Javascript函数的点击事件：

driver.execute_script("arguments[0].click()", ElementToClick)
