指数化指数定位
原标题:Get element position in index REVERSED

我做了一些格格格外工作,找到了一些非常复杂的解决办法,但只有一种简单的方法,可以让“Query”扭转一个要素指数。

Currently

$( .elementClass ).index(this);

请允许我谈谈“重要地图集”类中被点击的内容,但我需要扭转这一局面! 例如,我有5个“斜线”;一行中,如果第4个点被点击,我想返回的是1个而不是3个(第一个被送回为0)。

最佳回答
var elements = $( .elementClass );
var reversedIndex = (elements.length -elements.index(this))+1;
问题回答

仅将全部内容清单与<代码>elementClass等同起来,并从总数中减去指数。

var elements = $( .elementClass );
elements.click(function() {
    alert(elements.length - elements.index($(this)) - 1);
});

这里的工作实例更新后,第4项内容提醒“1”:。 http://jsfiddle.net/vM3Bb/1/

对我来说,这项工作是:

var element = jQuery(this);                
var reverseIndex = element.parent().children().length-(element.index()+1);
