为什么我的JQuery代码不起作用？

Question

I have some code that doesn't seem to work. I would think that this should give me an alert the instant I scroll, but no. Could anyone tell me what is wrong with it?

$(document).ready(function(){
    $(document).scroll(function(){
        alert("hi!");
    )};
});

Answer 1

Syntax error with bracket line 4 - correct code :

$(document).ready(function(){
    $(document).scroll(function(){
        alert("hi!");
    });
});

Answer 2

just typo: )}; should be });

Answer 3

Just tested this and works fine. Any errors in your console?

$(document).on( 'scroll', function(){ console.log('Event Fired'); });

Answer 4

$(document).ready(function(){
    $(document).scroll(function(){
        alert("hi!");
    });<---- please pay attention here!
});

you need a js editer(good editer can help you avoiding simple mistake)
