javascript - 如何为可移动 DIVS 创建显示更多/更少按钮

标签 javascript jquery html css

下面的代码由 2 个列表 Total Fruits 和 Random Fruits 组成，我可以将值从一个列表移动到另一个列表，反之亦然。我正在尝试在我的代码中实现显示更少/更多按钮，但很多在线示例似乎不适用于我当前的情况，因为我的 div 是可移动的。

对于我当前的代码，显示更多/更少按钮有效，但在我将所有值移动到另一个列表之后。当我单击“显示更多”时，它不会显示所有值，它会在中途中断。

任何帮助将不胜感激，因为我真的无法在网上找到一个好的例子。 

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'];
