目标:
1、通过layout布局
2、通过tree加载菜单
3、通过菜单去打开不同的tab页
ui框架:
easyui=jquery+html4(用来做后台的管理界面)
bootstrap=jquery+html5
layui
导包:

导入需要的工具类:

下载程序库并导入EasyUI的CSS和Javascript文件到您的页面。
一定要严格按照顺序
<link rel="stylesheet" type="text/css" href="easyui/themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="easyui/themes/icon.css"> <script type="text/javascript" src="easyui/jquery-1.7.2.min.js"></script> <script type="text/javascript" src="easyui/jquery.easyui.min.js"></script>
一旦你导入了EasyUI必须的文件,你就可以通过标记或Javascript定义一个EasyUI组件。例如:定义一个带可折叠功能的面板,你需要写的HTML代码如下:
<div data-options="region:‘north‘,border:false"
style="height:60px;background:#B3DFDA;padding:10px">north region</div>
<div data-options="region:‘west‘,split:true,title:‘West‘"
style="width:150px;padding:10px;">
菜单管理
<ul id="tt"></ul>
</div>
<div data-options="region:‘east‘,split:true,collapsed:true,title:‘East‘" style="width:100px;padding:10px;">east region</div>
<div data-options="region:‘south‘,border:false" style="height:50px;background:#A9FACD;padding:10px;">south region</div>
<div data-options="region:‘center‘,title:‘Center‘"></div>
实体类:
TreeNode.java
作用是通过TreeNode类转换成 tree_data1.json
package com.huang.entity;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class TreeNode {
private String id;
private String text;
private Map<String, Object> attributes = new HashMap<>();
private List<TreeNode> children = new ArrayList<>();
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public Map<String, Object> getAttributes() {
return attributes;
}
public void setAttributes(Map<String, Object> attributes) {
this.attributes = attributes;
}
public List<TreeNode> getChildren() {
return children;
}
public void setChildren(List<TreeNode> children) {
this.children = children;
}
public TreeNode(String id, String text, Map<String, Object> attributes, List<TreeNode> children) {
super();
this.id = id;
this.text = text;
this.attributes = attributes;
this.children = children;
}
public TreeNode() {
super();
}
@Override
public String toString() {
return "TreeNode [id=" + id + ", text=" + text + ", attributes=" + attributes + ", children=" + children + "]";
}
}
tree_data1.json
