Question

I have four divs in my html page something like this: the working fiddle implementation is here: http://jsfiddle.net/GxaCK/3/

 <div class="first">
    <p> First </p>
    </div>
    <div class="second">
    <p> Second </p>
    </div>
    <div class="third">
    <p> Third </p>
    </div>
    <div class="fourth">
    <p> Fourth </p>
    </div>

以及随后的 j:

$(function() {
    var firstCnt = 0,
        secondCnt = 0,
        thirdCnt = 0,
        fourthCnt = 0;
    $(".first").live("click", function(){
        firstCnt += 1;
        $(".first p").text(firstCnt);
    });

     $(".second").live("click", function(){
        secondCnt += 1;
        $(".second p").text(secondCnt);
    });

});

现在可以这样做。如果四舍五入点被点击或奇数倍,则将获得一定百分比。

I have the following doubt: 1. is this a goodway of implementation, in a project? 2. is there anything like even odd selector for clicks as well, as exists in css3

即使是奇迹,也可使用toggle 。见更新的jsfiddle here。
