java - 找到 Selenium 按钮但未执行单击

Question

我想单击由 xpath 标识的按钮，但它不起作用。

但是，单击操作没有错误。找到按钮，但未执行单击操作。

我尝试了以下解决方案：

解决方案 1

WebElement elem = driver.findElement(By.xpath("//button[@id='btn_M9pg_']"));
Actions actions = new Actions(driver);
actions.moveToElement(elem);
actions.click(elem);
Action a = actions.build();
a.perform();

解决方案 2

driver.findElement(By.xpath("//button[@id='btn_M9pg_']")).click();

你能帮我吗？非常感谢！

请在日志下方找到。btn_D_Ir_未找到按 id 的元素按钮，因为//button[@id='btn_M9pg_']未执行上一次单击 ( )。

You can try use WebDriverWait, like this:

new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("//button[@id='btn_M9pg_']"))).click();

And you can click via js, like this:

WebElement element = driver.findElement(By.id("btn_M9pg_")); 
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", element);
