Selenium在使用DropDown時選擇不工作，因爲它應該

我在使用硒選擇時遇到了一些問題。我工作的應用程序有60分鐘的時間。所以我不能保持循環運行，因爲它需要2個小時才能完成。Selenium在使用DropDown時選擇不工作，因爲它應該

所以我正在做的是我註銷並再次登錄，以獲得新的會話。

但是我登錄後，Selenium Select沒有從下拉列表中選擇可見的文本。雖然循環完美。

如果任何人有任何想法，它會如何工作罰款請分享。

謝謝， Varun。

這是我的代碼;

你嘗試過什麼到目前爲止，和你得到了什麼異常？告訴我們你的代碼。 –

嘿亞歷山大，謝謝你的迴應，我已經發布了我的代碼.. – user3020548

什麼行爲的預期和你得到什麼？ –

好了，似乎重新加載頁面後，你actualy 得到的StaleElementReferenceException @這些線路當你抓住它時你什麼都不做。

for (String sTextTime : sListItemTextListBox3) { 

      iCountGeo++; 

      iAttempts = 0; 
      while (iAttempts < 5) { 
       try { 
        oList3.selectByVisibleText(sTextTime); 
        break; 
       } catch (StaleElementReferenceException e) { 
       } 
       iAttempts++; 
      } 
     }

的POIN是，在DropDownValidation()方法限定oList的是錯誤的。這部分

if (iCountGeo == 2) { 

       iCountGeo = 0; 
       dev.navigate().to("http://www.google.com"); 
       dev.navigate().to(sHomeURL); 
       continue; 
      }

僅適用於sListItemTextListBox3和sListItemTextListBox4選項的選擇。重新加載頁面後，oList3和oList4會變陳舊。因此，我建議將這些零件（oList3 = new Select(dev.findElement(By.id("tool3")));）移動到oList3.selectByVisibleText(sTextTime);之前，這些for陳述中的每個都位於try-catch塊內。

for (String sTextProduct : sListItemTextListBox4) { 

       iAttempts = 0; 
       while (iAttempts < 5) { 
        try { 
         oList4 = new Select(dev.findElement(By.id("tool4"))); //here 
         oList4.selectByVisibleText(sTextProduct); 
         break; 
        } catch (StaleElementReferenceException e) { 
        } 
        iAttempts++; 
       }

PS在Python上嘗試了這一點，但邏輯是一樣的。

UPDATE順便說一句，這樣做，你也應該能夠在DropDownValidation()擺脫這些聲明：

iAttempts = 0; 
while (iAttempts < 5) { 
    try { 
     oList1 = new Select(dev.findElement(By.id("tool1"))); 
     break; 
    } catch (StaleElementReferenceException e) { 
    } 
    iAttempts++; 
}

Selenium在使用DropDown時選擇不工作，因爲它應該
