菜单

node在五个div之间活动,用ztree落成

2019年8月3日 - CSS/CSS3

贯彻思路:

1、ztree中节点是透过叁个json的Array作为数据源、,所以一贯操作json字符串,然后转为json对象数组。

2、然后用新组成的json数组对象重新早先化ztree对象。

复制代码 代码如下:

<link rel=”stylesheet” href=”demo.css” type=”text/css”>
<link rel=”stylesheet” href=”zTreeStyle.css” type=”text/css”>
<script type=”text/javascript”
src=”jquery-1.4.4.min.js”></script>
<script type=”text/javascript”
src=”jquery.ztree.core-3.5(1).js”></script>
<script type=”text/javascript”>

        var zTreeObj2;
        var leftDivStr = “[“;
        var rightDivStr = “[“;

            edit: {
                enable: false,
                showRemoveBtn: false,
                showRenameBtn: false
            },
            data: {
                simpleData: {
                    enable: true
                }
            },
            callback: {
                //onClick : menuOnClick
            }
        };
        function menuOnClick(event, treeId, treeNode, clickFlag) {

        }
        //注册toSource函数,化解ie不辅助Array的toSource()方法的主题材料
        Array.prototype.toSource = function (){
             var str = “[“;
