如何使用phantomjs无头浏览器处理selenium中的警报

Question

Selenium版本：3.4.0 phantomjs版本：2.1.1 java：1.8.0_151

我尝试了下面的东西，但它对我没用。

在这里输入代码

1：

webDriver instanceof PhantomJSDriver){
              JavascriptExecutor je = (JavascriptExecutor) driver;
              je.executeScript("window.alert = function(){};");
              je.executeScript("window.confirm = function(){return true;};");    
              System.out.println("Alert has been handled"); }
            else {
                  Alert a1 = driver.switchTo().alert();
                  a1.accept();  
              }

2：

      /*((PhantomJSDriver)driver).executeScript("window.alert = function(){}");
      ((PhantomJSDriver)driver).executeScript("window.confirm = function(){return true;}");*/

3：

      PhantomJSDriver phantom = (PhantomJSDriver) driver;
            phantom.executeScript("window.confirm = function(){return true;};");

4：

    ((JavascriptExecutor)driver).executeScript("window.alert = function(msg){};");
 ((JavascriptExecutor)driver).executeScript("window.confirm = function(msg){return true;};");

5：

PhantomJSDriver phantom = (PhantomJSDriver)driver;
       phantom.executePhantomJS("var page = this;" +
               "page.onAlert = function(msg) {" +
                      "console.log('ALERT: ' + msg);" +
               "};");

       phantom.executePhantomJS("var page = this;" +
               "page.onConfirm = function(msg) {" +
                      "console.log('CONFIRM: ' + msg);"+ "return true;" +"};");

除此之外，请你建议。
