먼저layui에 대해 알아봅시다
layui(동음어: UI와 유사)는 자체 모듈 사양을 사용하여 작성된 프런트엔드 UI 프레임워크로 네이티브 HTML/CSS의 작성 및 구성 형식을 따릅니다. /JS. 임계값이 매우 낮으며 사용할 준비가 되었습니다. 외부는 미니멀하지만 내부는 꽉 차 있습니다. 크기가 가볍고 구성 요소가 풍부합니다. 핵심 코드부터 API까지 모든 세부 사항이 신중하게 제작되어 빠른 인터페이스 개발에 매우 적합합니다.

이번에 사용한 jar 패키지
index.js
$(function () { $.ajax({ type: "post", url: "menuAction.action?methodName=treeMenu", dataType: "json", /*data: {// 传给servlet的数据, role_id: MenuHid, right_code: "-1", d: new Date() },*/ success: function (data) { console.info(data); layui.tree({ elem: '#demo',// 传入元素选择器 nodes: data, // spread:true, click: function (node) {// 点击tree菜单项的时候 var element = layui.element; var exist = $("li[lay-id='" + node.id + "']").length;//判断是不是用重复的选项卡 if (exist > 0) { element.tabChange('tabs', node.id);// 切换到已有的选项卡 } else { if (node.attributes.menuURL != null && node.attributes.menuURL != "") {// 判断是否需要新增选项卡 element.tabAdd( 'tabs', { title: node.name, content: '<iframe scrolling="yes" frameborder="0" src=" ' + node.attributes.menuURL + ' " width="100%" height="100%"></iframe>'// 支持传入html , // width="99%" height="99%" id: node.id }); element.tabChange('tabs', node.id); } } } }); } }); })
