>  phantomjs因为是无界面的，无法处理动态js渲染的alert弹窗，因此无法使用常规的 switch\_to\_alert() 来处理弹窗，否则将会报错。查阅资料发现其实phantomjs自带了处理弹窗的API，这里只需要在selenium中的调用phantomjs自带的API就行。

browser = webdriver.PhantomJS(executable_path = os.path.join(mypath,"browser\\phantomjs.exe"))
    #selenium调用phantomjs的API来解决alert弹窗问题
            def shutdown_alert(self):
            alert_script = """
                            var page = this ;
                            page.onAlert = function(msg){
                            console.log(msg);};"""
            browser.command_executor._commands['executePhantomScript'] = ('POST', '/session/$sessionId/phantom/execute')
            browser.execute('executePhantomScript', {'script': alert_script, 'args': []})
    
    #该函数需要在触发alert弹窗前执行，否则会因为alert的阻塞效应而失效
    
    
    #同理，对confirm弹窗的处理方式如下：
    
        def shutdown_confirm(self):
            confirm_script = """
                                    var page = this ;
                                    page.onConfirm = function(msg) {
                                    console.log(msg);
                                    return true;
                                    };"""
            browser.command_executor._commands['executePhantomScript'] = ('POST', '/session/$sessionId/phantom/execute')
            browser.execute('executePhantomScript', {'script': confirm_script, 'args': []})

在selenium中调用Phantomjs的API的方法参考：
