LayUI拓展组件:TreeSelect树形下拉选择器

项目介绍

基于 layui和ztree的树形下拉选择器。支持异步加载,提供点击回调和加载完成后的回调,支持搜索、占位符修改、手动选中节点以及刷新树结构,更多功能参见使用文档。 使用文档:https://wujiawei0926.gitee.io/treeselect/docs/doc.html

使用示例

<input type="text" id="tree" lay-filter="tree" class="layui-input">

<script>
    layui.use(['treeSelect','form'], function () {
        var treeSelect= layui.treeSelect;

        treeSelect.render({
            // 选择器
            elem: '#tree',
            // 数据
            data: 'data/data3.json',
            // 异步加载方式:get/post,默认get
            type: 'get',
            // 占位符
            placeholder: '修改默认提示信息',
            // 是否开启搜索功能:true/false,默认false
            search: true,
            // 点击回调
            click: function(d){
                console.log(d);
            },
            // 加载完成后的回调函数
            success: function (d) {
                console.log(d);
//                选中节点,根据id筛选
//                treeSelect.checkNode('tree', 3);

//                获取zTree对象,可以调用zTree方法
//                var treeObj = treeSelect.zTree('tree');
//                console.log(treeObj);

//                刷新树结构
//                treeSelect.refresh();
            }
        });
    });
</script>

提示

  • 返回数据中的open属性用来判断是否自动展开节点
  • 返回数据格式与ztree要求的格式相同
