【解决方案1】：

您可以对某些特定内容使用显式等待。等待所有元素并不理想。没有特定的方法来检查所有 Ajax 元素是否已加载。如果由于 Ajax 加载而无法使用显式等待访问某些特定元素，请回答。

【讨论】：

你能给出一个代码示例吗？我不知道如何使用它
WebElement 元素= null;布尔未找到=真； int numberOfTries = 0; while ( notFound && 尝试

【解决方案2】：

使用此代码

WebElement element= null;
  boolean notFound= true;
  int numberOfTries= 0;
  while ( notFound && numberOfTries < 60 ) 
 {
    numberOfTries += 1;
     try 
     {
      element =  driver.findElement( locator );
      if(element.isDisplayed && element.isClickable)//Desired condition
       {         
      notFound = false; //Element identified
       }
    } 
  catch ( Exception e ) 
    {                       
      system.out.println("Exception occured")
      notFound = true;
 }
