javascript - Selenium: "is not clickable at point"如何等待所有脚本加载完毕

Question

我有 3 次等待:

wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//*[@id='pagecontrols']/input[1]")));
wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//*[@id='pagecontrols']/input[1]")));
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//*[@id='pagecontrols']/input[1]")));

对于相同的元素，但等待之后，当我想点击时

driver.findElement(By.xpath("//*[@id='pagecontrols']/input[1]")).click();

我有:

"Element (...) is not clickable at point"

我试图通过添加此部分来等待 JavaScript 完全加载

public void waitForLoad(WebDriver driver) 
{
  ExpectedCondition<Boolean> pageLoadCondition = new ExpectedCondition<Boolean>() 
  {
    public Boolean apply(WebDriver driver) 
    {  
      return ((JavascriptExecutor)driver).executeScript("return document.readyState").equals("complete");
    }
  };
  WebDriverWait wait = new WebDriverWait(driver, 30);
  wait.until(pageLoadCondition);
}

但是这不起作用(这在不同的地方有帮助，所以通常这在某些情况下有帮助)，也许我做错了什么？ 我想我也应该等待 jQuery，但说实话，我确实知道怎么做(我已经找到了一些解决方案，但它们对我不起作用)

Exception in thread "main" org.openqa.selenium.WebDriverException: unknown error: Element <input type="button" class="btn btn-default" data-toggle="modal" data-target="#adduser" data-localize="adduser" value="Add user"> is not clickable at point (1397, 97). Other element would receive the click: <div class="blockUI blockOverlay" style="z-index: 1000; border: none; margin: 0px; padding: 0px; width: 100%; height: 100%; top: 0px; left: 0px; background-color: rgb(0, 0, 0); cursor: wait; position: absolute; opacity: 0.304712;"></div>

还有一件事:当我添加时 线程.sleep(500); 在单击元素之前它正在工作，但我想摆脱这些 sleep

避免这种“烟雾”UI 阻塞的唯一真正有效的方法是使用 Thread.sleep(); 3000 毫利斯，瞧!
