触发鼠标在随机元素上输入 [英] trigger mouse enter on random element

问题描述

我有这个javascript:

I have this javascript:

$('.foto').filter(function(index) {
    return index == Math.floor(Math.random() * 8) + 1;
}).trigger('mouseover');

我想在照片上模拟悬停效果，但是滤镜功能不起作用. 我也尝试过

I want to simulate a hover effect on a photo, but somehow the filter function does not work. I also tried

$('.foto:random').trigger('mouseover');

推荐答案

尝试一下:

$.fn.rand = function(){
    return this.eq(Math.floor(Math.random()*this.length));
};
$(".foto").rand().trigger("mouseover");

注意:，您只需定义一次$.fn.rand，通常只需在包含jquery之后即可.

Note: you only have to define $.fn.rand once, usually right after including jquery.
