layui checkbox 样式

layui  checkbox扩展插件：

 一、新建  checkbox.css 样式文件

.checkBox .block{float:left; margin:5px;padding:6px 6px;width:80px;height:18px;text-align:center; border:1px solid #ccc;position:relative;cursor:pointer;overflow:hidden;}
.checkBox .block .choice{position:absolute;right:0px;bottom:0px;display:none;}
.checkBox .block.on{border:1px solid #1E9FFF;}
.checkBox .block.on .choice{position:absolute;right:0px;bottom:0px;display:block;}
.checkBox .block.on .choice .triangle{position:absolute;right:0px;bottom:0px;border-bottom:18px solid #1E9FFF;border-left: 18px solid transparent;}
.checkBox .block.on .choice .right{position:absolute;right:5px;bottom:5px;width:10px;height:10px;}
.checkBox .block .del{width:18px; height:18px; background:#fff; border:0px solid #ccc; border-radius:3px; overflow:hidden; cursor:pointer; position:absolute; bottom:-20px; right:0px; transition: background .3s ease, border .2s ease, bottom .2s ease;display:block;}
.checkBox .block .del:hover{background:#FF5722; border:1px solid #FF5722;}
.checkBox .block:hover .del{bottom:0px;}
.checkBox .block.on .del{display:none}

 二、新建  checkbox.js 文件

layui.define('jquery', function(exports){
    "use strict";
    var $ = layui.$
    ,hint = layui.hint();
    var CheckBox = function(options){
        this.options = options;
    };
    //初始化
    CheckBox.prototype.init = function(elem){
        var that = this;
        elem.addClass('checkBox'); //添加checkBox样式
        that.checkbox(elem);
    };
    //树节点解析
    CheckBox.prototype.checkbox = function(elem,children){
        var that = this, options = that.options;
        var nodes = children || options.nodes;
        layui.each(nodes, function(index, item){
            var li = $(['<li class="block'+(item.on?' on':'')+'" value="'+item.name+'" onmouseover="layui.layer.tips(\''+item.type+'\',this,{tips:2})" onmouseout="layui.layer.closeAll(\'tips\');">'+item.name,'<i class="choice"><i class="triangle"></i><i class="right layui-icon layui-icon-ok"></i></i><i class="del"><i class="layui-icon layui-icon-delete"></i></i><span class="hide">'+(item.on?'<input type="hidden" name="'+item.name+'" value="'+item.type+'">':'')+'</span></li>'].join(''));
            elem.append(li);
            //触发点击节点回调
            typeof options.click === 'function' && that.click(li, item);
            //触发删除节点回调
            typeof options.del === 'function' && that.del(li, item);
        });
    };
    //点击节点回调
    CheckBox.prototype.click = function(elem, item){
        var that = this, options = that.options;
        elem.on('click', function(e){
            elem.toggleClass("on");
            if(elem.hasClass("on")){
                item.on = true;
                elem.children("span.hide").html('<input type="hidden" name="'+item.name+'" value="'+item.type+'">');
            }else{
                item.on = false;
                elem.children("span.hide").html('');
            }
            layui.stope(e);
            options.click(item);
        });
    };
    //点击节点回调
    CheckBox.prototype.del = function(elem, item){
        var that = this, options = that.options;
        elem.children('i.del').on('click', function(e){
            var index = layer.confirm('确定删除 ['+item.name+'] 吗？', {
                btn: ['删除','取消']
            }, function(){
                layer.close(index);
                if(options.del(item)){
                    elem.closest(".block").remove();
                    layui.stope(e);
                }
            });
            return false;
        });
    };

    //暴露接口
    exports('checkbox', function(options){
        var checkbox = new CheckBox(options = options || {});
        var elem = $(options.elem);
        if(!elem[0]){
            return hint.error('layui.checkbox 没有找到'+ options.elem +'元素');
        }
        checkbox.init(elem);
    });
}).link('checkbox.css','checkboxcss');

三、index.html 代码

<div id="testbox"></div>

四、index.js 引用

    $("#testbox").children("li").remove();
        checkbox({
            elem: "#testbox"
            , nodes: [
                { "id": 1, "name": "全域企业", "type": "区域碳排放量", "on": true }
                , { "id": 2, "name": "太阳谷企业", "type": "太阳谷产业园区企业", "on": false }
            ]
            , click: function (node) {
                //id: 1, name: "碳排放", on: false, type: "区域碳排放量"

            }
            , del: function (node) {
                console.log("删除", node);
                return true;
            }
        });
