找不到Java-Selenium WebElement錯誤

Question

我硒有問題。

我想將一些String content發送到ID =“ source”的Web上的某個元素，並將其提交給我，這是我的代碼

driver.get("http://hiriji.com/");
        WebElement viet = driver.findElement(By.id("source"));
        viet.sendKeys(content);
        viet.submit();

效果很好，直到內容太大為止。

后

viet.sendKeys(content);

網絡突然更改為404錯誤頁面。 所以它在出現錯誤

viet.submit();

我的問題是如何忽略此錯誤並繼續以下代碼。 我不需要將所有內容發送到網絡，如果太大，則可以忽略...

stacktrace說：

Answer 1

只需檢查內容的長度。如果長度超出限制，請勿提交表單。

if(content.length()<=acceptableLimit)
viet.sendKeys(content);
    viet.submit();

Answer 2

可能原因：手術后

driver.get("http://hiriji.com/");

您沒有獲得應該在頁面上加載的所有元素。 添加隱式等待driver.manage().timeouts().implicitlyWait(5,TimeUnit.SECONDS); 驗證我是否正確

driver.get("http://hiriji.com/");
driver.manage().timeouts().implicitlyWait(5,TimeUnit.SECONDS);
 WebElement viet = driver.findElement(By.id("source"));
        viet.clear();
        viet.sendKeys(content);
        viet.submit();//or as alternative try to click on 'submit' button
