以上是html代码片段

我正在尝试使用以下 xpath :

driver.findElement(By.xpath("//*[@id=\"attachment-trigger-ember1000\"]")).click();

但它不起作用。

错误消息:

element not found exception

您可能想使用 By.id 来代替: https://seleniumhq.github.io/selenium/docs/api/java/org/openqa/selenium/By.html#id-java.lang.String-

driver.findElement(By.id("attachment-trigger-ember1000")).click();
