优化selenium .clear()
时间: 2023-07-19 14:46:19 浏览: 76
在使用 Selenium 的 `clear()` 方法时,有时会出现性能问题。下面是一些优化方法:
1. 尽可能在填充输入框之前就清空它们,这样可以避免多次使用 `clear()` 方法。
2. 如果要清空多个输入框,可以使用 JavaScript 代码一次性清空它们。示例代码:
```
driver.execute_script("var inputs = document.getElementsByTagName('input'); for(var i = 0; i < inputs.length; i++) {inputs[i].value='';}")
```
3. 使用 `send_keys(Keys.CONTROL + "a")` 方法来选中文本,然后使用 `send_keys(Keys.BACKSPACE)` 方法删除文本。
4. 如果 `clear()` 方法仍然很慢,可以考虑使用 `driver.execute_script("arguments[0].value = '';", element)` 方法来清空输入框。
这些方法都可以帮助你优化 Selenium 的 `clear()` 方法。

代码中第8行和第9行的XPath表达式缺少元素的标签名,应该补全XPath表达式,例如第8行应该改为:
```python
aaa = driver.find_element(By.XPATH,'//input[@id="kw"]')
```
同时,最后一行代码缺少操作,应该在该行代码之前添加一行,定义一个变量或者进行其他操作,否则最后一行代码会出现语法错误。
另外,建议在对话框中发送消息之前,先判断对话框是否已经打开,可以使用`wx.GetChildren()`方法获取对话框中所有控件,判断控件是否存在来判断对话框是否已经打开。另外,在发送消息之前,可以使用`wx.SendKeys()`方法将消息内容粘贴到输入框中,而不是使用`selenium`的`send_keys()`方法,这样可以避免鼠标焦点的问题。

可以尝试以下优化方式:
1. 使用显式等待代替 time.sleep(),可以更加精准地等待页面元素的加载,提高代码的执行效率。
2. 将重复的元素定位代码提取出来,封装成函数,减少代码冗余。
3. 将多个操作封装成一个函数,提高代码的可读性和可维护性。
下面是优化后的代码:
```python

return WebDriverWait(driver, 10).until(EC.presence_of_element_located(locator))
def click_element(driver, locator):
element = wait_for_element(driver, locator)
element.click()
def set_text(driver, locator, text):
element = wait_for_element(driver, locator)
element.clear()
element.send_keys(text)
def scroll_down(driver):
win32api.mouse_event(win32con.MOUSEEVENTF_WHEEL, 0, 0, -1000)
def set_activity_template(driver):
driver.get("http://cjwxb-test.dianpusoft.cn/new-interact/interact/setActivityTemplate?activityType=10021")
click_element(driver, (By.XPATH, '//*[@id="setActivityTemplate"]/div/div[2]/form/div[3]/div[1]/div'))
click_element(driver, (By.XPATH, '//*[@id="setActivityTemplate"]/div/div[2]/form/div[3]/div[1]/div/div/button'))
