我面临一个挑战,我需要改变全球价值。请参阅下面的代码,每当用户单击#first时,它将计算时间并存储在服务器端。但是,我希望实现这一点,如果我点击第二个,全局值变为1.因此,当我再次点击#first时,它再次从1开始。我怎么能实现这一点,欣赏?

var count=1;//global value

$('#first').on('click',function(){	
     count++			
});

$('#second').on('click',function(){	
     //count--(minus)?? make the global value 
     //become 1 no matter how many time I have clicked #first		
});

Javascript

var count=1;//global value

    $('#first').on('click',function(){  
             count++ ;          
    });

    $('#second').on('click',function(){ 
             count=1; //make the global value become 1 no matter how many time I have clicked #first        
    });
