Question

我对硒有一些问题。

我想将一些String content发送到我网站上的ID =“source”的元素并提交这是我的代码

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

效果很好，直到内容太大。

后

viet.sendKeys(content);

网页突然变为404错误页面。所以它在

时出错了

viet.submit();

我的问题是如何忽略此错误并继续下面的代码。我不需要将所有内容发送到网络，如果它太大就可以忽略......

堆栈跟踪说：

Answer 1

只检查内容的长度。如果超出限制，请不要让表单提交。

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

Answer 2

可能的原因：手术后

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

您没有获得应该在页面上加载的所有元素。添加隐式等待driver.manage().timeouts().implicitlyWait(5,TimeUnit.SECONDS);以验证我是对还是

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

找不到Java-Selenium WebElement错误
