模数如果否则算错误

Question

function expand(div_block_id, expansion_class, original_class, time, callback_function_original, callback_function_expand) {
        console.log("entered expand");
        var id = '#' + div_block_id; //ID received by function
        counter = counters[div_block_id + '_counter']; //Associates the counter per div block respectively 

        //Original ID of style
        $(id).click(function () {
            console.log("entered expand on click");
            //If the click counter is even then animate back to original state
            $("#dialog").remove();
            console.log(counter);
            if (++counter % 2 == 0) {
                console.log('counter =>'+counter);
                console.log('counter array index value ='+ counters[div_block_id + '_counter']);
                counters[div_block_id + '_counter'] = counter;
                console.log("entered expand if");
                $(this).animate(original_class, {
                    duration: time, //animation duration
                    start: callback_function_original //make animation happen symultaneously with callback
                });
                console.log("animated original class");
                console.log(counters);
            } else {
                //++counter;
                counters[div_block_id + '_counter'] = counter;
                console.log("entered expand else");
                //Expand to desired css
                $(this).animate(expansion_class, {
                    duration: time,
                    start: callback_function_expand //make animation happen symultaneously with callback
                });
                console.log("animated expand class");
                console.log(div_block_id + '=' + counters[div_block_id + '_counter']);
                //Reset counter on every uneven click so it wont get bigger
                //counters[div_block_id + '_counter'] = 0;
            }
            console.log("exited expand");
        });
    };
}

我有一个基本的if else情况，它假设检测偶数和奇数点击

$(id).click(function(){
     if(++counter % 2 == 0){
        ...add some animations
     }else{
       do some other animation
     }

但是当我打开两个或更多个div时，计数器会失去计数，但是当我看到控制台时，数组会显示出来。我想要做的就是点击任何div，如果主div打开然后你可以展开那个div，但如果你关闭主div与其他div打开所有它们应该关闭。

我知道得到它有点难，你可以看到这个fiddle
