如何为可移动DIVS创建显示更多/更少显示按钮

时间:2018-06-28 06:53:55

标签: javascript jquery html css

我下面的代码包含2个列表中的“水果总数”和“随机水果”,我可以将值从一个列表移动到另一个列表,反之亦然。我正在尝试在代码中实现“显示更少/更多”按钮,但是由于我的div是可移动的,因此很多在线示例似乎不适用于当前情况。

对于我当前的代码,“显示更多/更少”按钮有效,但是在我将所有值移至其他列表之后。当我单击“显示更多”时,它并不能显示所有值。

任何帮助将不胜感激,因为我真的无法在线找到一个很好的例子。

var redpill = {};
var greenpill = {};
var randompill = {};


var key = "Red Fruits";
redpill[key] = ['Apple', 'Cherry', 'Strawberry', 'Pomegranate', 'Rassberry', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew'];

var key2 = "Green Fruits";
greenpill[key2] = ['Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew'];

var key3 = "Random Fruits";
randompill[key3] = ['Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew', 'Watermelon', 'Durian', 'Avacado', 'Lime', 'Honeydew'];
