jQuery无法识别点击

Question

I am building a webapp (I'm new to javascript), and jquery refuses to do anything when I click on something that has a .click listener attached to it. In addition, it won't animate. I am doing something wrong, and can't figure what.

Code:

 function loadTabBar()
{
    person = false;
    sale = false;
    current = false;
    wine = false;
    if(!person && !sale && !current && !wine)
    {
        justOpened();
    }

    function useTabBar(){

    $('#PersonDiv').click(function()
    {
        alert('hi')
        activatePerson();
    });
    $('#Current').click(function()
            {
                activateCurrent();
            });
    $('#Sale').click(function()
            {
                activateSale();
            });
    $('#Wine').click(function()
            {
                activateWine();
            });

    function activatePerson()
    {
        if(!person)
        {
            var newImg="#Person";
            if(sale)
            {
                var oldImg="#Sale"
                changeImg(oldImg, newImg);
            }
            if(wine)
            {
                var oldImg="#Sale"
                changeImg(oldImg, newImg);
            }
            if(current)
            {
                var oldImg="#Sale"
                changeImg(oldImg, newImg);
            }
            person = true;
            current = false;
            wine = false;
            sale = false;

        }
    }
    function activateSale()
    {
        if(!sale)
        {
            var newImg="#Sale"
            if(person)
            {

                var oldImg="#Person"
                changeImg(oldImg, newImg);
            }
            if(wine)
            {
                var oldImg="#Wine"
                changeImg(oldImg, newImg);
            }
            if(current)
            {
                var oldImg="#Current"
                changeImg(oldImg, newImg);
            }
            person = false;
            current = false;
            wine = false;
            sale = true;
        }
    }
    function activateWine()
    {
        if(!wine)
        {
            var NewImg = "#Wine"
            if(sale)
            {
                var oldImg="#Sale"
                changeImg(oldImg, newImg);
            }
            if(person)
            {
                var oldImg="#Person"
                changeImg(oldImg, newImg);
            }
            if(current)

                changeImg(oldImg, newImg);
            }
            if(wine)
            {
                var oldImg="#Wine"
                changeImg(oldImg, newImg);
            }
            if(person)
            {
                var oldImg="#Person"
                changeImg(oldImg, newImg);
            }
            person = false;
            current = true;
            wine = false;
            sale = false;
        }
    }
    function changeImg(oldImg, newImg)
    {
            $(oldImg).fadeOut('fast', function()

Answer 1

You will have to call loadTabBar() or instead of that you can put your code in ready instead of loadTabBar().

$(document).ready(function(){

//code goes here

});

Answer 2

You aren't ever calling loadTabBar() . I'm not sure why you have everything wrapped inside it?

Answer 3

You have to call your loadTabBar() function before you can use any of the stuff inside. Try calling your function, then the clicks should work...
