Question

我試着點擊以下元素：

選擇專業...

我用下面的代碼：

嘗試＃1：

new Actions(driver).moveToElement(driver.findElement(By.xpath("//div[@class='dropbox_input holder']"))).perform(); 

driver.findElement(By.xpath("//div[@class='dropbox_input holder']")).click(); 

嘗試＃2：

new Actions(driver).moveToElement(driver.findElement(By.xpath("//div[contains(@class,'dropbox_input') and contains(@class, 'holder')]"))).perform(); 
      driver.findElement(By.xpath("//div[contains(@class,'dropbox_input') and contains(@class, 'holder')]")).click(); 

Attempt #3: 

new Actions(driver).moveToElement(driver.findElement(By.cssSelector("div.strong div.dropbox_arrow"))).perform(); 
      driver.findElement(By.cssSelector("div.strong div.dropbox_arrow")).click(); 

預期產量是多少？你看到了什麼呢？ 預計會看到耗盡下拉菜單，但看到空白頁面的新Chrome窗口。

相同的代碼工作以及在Firefox。

Answer 1

您在Chrome v30上使用ChromeDriver v2.1。

更新您的ChromeDriver到最新版本2.1不支持Chrome瀏覽器30

的影響將是任何電話，包括導航，是行不通的，因此任何發現元話費就出錯了。

Answer 2

首先，你的xpath或selector真正起作用的，如果你選擇了它在，比方說，螢火蟲？如果是的話，試試這個選項

new Actions(driver).moveToElement(driver.findElement(By.cssSelector("selector"))) 
    click.perform();
