如何关闭Selenium脚本运行中弹出的弹窗？点击报错解决方案

使用Selenium脚本处理页面弹窗时，无法关闭弹窗，报错信息如下：

color="accent" class="mat-focus-indicator mat-button mat-button-base mat-accent">... is not clickable at point (684, 847). Other element would receive the click:

针对弹窗关闭失败的问题，可从以下几个方向优化：

1. 修正弹窗定位逻辑，避免固定ID #

弹窗ID（如mat-dialog-3）是动态生成的，多次打开弹窗后ID会变化，改用通用类名定位弹窗容器：

# 替换原固定ID的弹窗定位
popup_element = WebDriverWait(driver, 10).until(
    EC.visibility_of_element_located((By.CLASS_NAME, "mat-dialog-container"))
)

2. 精确定位弹窗内的关闭按钮 #

结合弹窗容器缩小定位范围，避免匹配到页面其他位置的同类按钮：

close_button = WebDriverWait(popup_element, 10).until(
    EC.element_to_be_clickable((By.XPATH, ".//button[contains(@aria-label, 'Close dialog')]"))
)

3. 处理元素遮挡问题 #

报错提示按钮被其他元素遮挡，可先将按钮滚动到可视区域，再尝试点击：

# 滚动到按钮位置
driver.execute_script("arguments[0].scrollIntoView(true);", close_button)
# 优先尝试原生点击，失败再用JS点击
try:
    close_button.click()
except:
    driver.execute_script("arguments[0].click();", close_button)

4. 替换固定等待，用显式等待提升稳定性 #

去掉time.sleep(2)，改用等待弹窗内关键元素（如表格）加载完成：

# 等待弹窗内的表格出现，确认弹窗加载完成
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.ID, "customers")))

优化后的核心代码片段 #

for listss in lists:
    try:
        listss.click()
        # 等待弹窗内表格加载完成，替代固定sleep
        WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.ID, "customers")))
        
        # 动态定位弹窗容器
        popup_element = WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.CLASS_NAME, "mat-dialog-container")))
        
        # 爬取表格数据（原逻辑不变）
        table = popup_element.find_element(By.ID, "customers")
        rows = table.find_elements(By.TAG_NAME, "tr")
        table_data = []
        for row in rows:
            cells = row.find_elements(By.TAG_NAME, "td")
            row_data = [cell.text for cell in cells]
            table_data.append(row_data)

        # 写入CSV（原逻辑不变）
        with open("mmei.csv", mode='a', newline='') as file:
            writer = csv.writer(file)
            writer.writerows(table_data)

        # 定位并关闭弹窗
        close_button = WebDriverWait(popup_element, 10).until(
            EC.element_to_be_clickable((By.XPATH, ".//button[contains(@aria-label, 'Close dialog')]"))
        )
        driver.execute_script("arguments[0].scrollIntoView(true);", close_button)
        try:
            close_button.click()
        except:
            driver.execute_script("arguments[0].click();", close_button)
            
    except Exception as e:
        print("Error processing popup:", e)
        pass
