zTree和SweetAlert插件初探

1.zTree插件简介

zTree是一个依靠 jQuery实现的多功能“树插件”。优异的性能、灵活的配置、多种功能的组合是zTree最大优点。专门适合项目开发，尤其是树状菜单、树状数据的Web显示、权限管理等等。

官网地址：http://www.treejs.cn/v3/main.php#_zTreeInfo

2.zTree资源管理实例

⑴ 引入zTree的js和css文件：

 <script type="text/javascript" src="/assets/scripts/zTree_v3/js/jquery-1.4.4.min.js"></script>
 <script type="text/javascript" src="/assets/scripts/zTree_v3/js/jquery.ztree.core-3.5.js"></script>
 <script type="text/javascript" src="/assets/scripts/zTree_v3/js/jquery.ztree.excheck-3.5.js"></script>
 <link rel="stylesheet" href="/assets/scripts/zTree_v3/css/zTreeStyle/zTreeStyle.css" type="text/css" />

⑵ zTree的页面元素：通过读取隐藏的Input输入框中传递的JSON字符串初始化zTree树。

 <input type="hidden" id="zTreeNodes" value="{{_DATA_.ztreeNodes}}" />
 <span class="resourceSpan" >父资源<label style="color:#ff0000;">*</label>：</span>
 <div id="parentResource" class="ztree"></div>

⑶ js简单初始化zTree树：

var zNodesStr = document.getElementById("zTreeNodes").value;
var zNodes = JSON.parse(zNodesStr);
$.fn.zTree.init($("#parentResource"), setting, zNodes);

⑷ 给Ztree赋初值的java代码:

public UserResourceDTO initNewResources() {
    List<UsersResource> resourceList = new ArrayList<UsersResource>();
    resourceList = usersResourceService.getAllResource();
    JSONArray jsonNodes = new JSONArray();
    for (UsersResource tempRes : resourceList) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("id", tempRes.getId());
        jsonObject.put("pId", tempRes.getParentId());
        jsonObject.put("name", tempRes.getName());
        if (tempRes.getParentId() == 0) {
        jsonObject.put("checked", true);
        jsonObject.put("open", true);
        } else {
        jsonObject.put("open", false);
        }
        jsonNodes.add(jsonObject);
    }
    UserResourceDTO userResourceDTO = new UserResourceDTO();
    userResourceDTO.setZtreeNodes(jsonNodes.toString());

    return userResourceDTO;
    }

⑸ UserResourceDTO代码:

package com.ouc.mkhl.platform.usersAuth.dto;

import java.io.Serializable;

//RBAC权限管理-资源信息
public class UserResourceDTO implements Serializable {

    private static final long serialVersionUID = -889200123123123L;

    private Integer id;   //资源Id

    private String name;   //资源名称

    private String description;   //资源描述

    private String url;  //链接地址

    private String type;  //资源类型：0-URL资源，1-组件资源

    private String status;  //状态：0-隐藏，1-展示

    private String code;  //标识码

    private String configuration;  //配置项

    private String moduleName;  //模块名称

    private Integer orderIndex;   //排序号

    private Integer parentId;  //父资源

    private String ztreeNodes; // 关联资源结点

    public Integer getId() {
    return id;
    }

    public void setId(Integer id) {
    this.id = id;
    }

    public String getName() {
    return name;
    }

    public void setName(String name) {
    this.name = name == null ? null : name.trim();
    }

    public String getDescription() {
    return description;
    }

    public void setDescription(String description) {
    this.description = description == null ? null : description.trim();
    }

    public String getUrl() {
    return url;
    }

    public void setUrl(String url) {
    this.url = url == null ? null : url.trim();
    }

    public String getType() {
    return type;
    }

    public void setType(String type) {
    this.type = type;
    }

    public String getStatus() {
    return status;
    }

    public void setStatus(String status) {
    this.status = status;
    }

    public String getCode() {
    return code;
    }

    public void setCode(String code) {
    this.code = code == null ? null : code.trim();
    }

    public String getConfiguration() {
    return configuration;
    }

    public void setConfiguration(String configuration) {
    this.configuration = configuration == null ? null : configuration
        .trim();
    }

    public String getModuleName() {
    return moduleName;
    }

    public void setModuleName(String moduleName) {
    this.moduleName = moduleName == null ? null : moduleName.trim();
    }

    public Integer getOrderIndex() {
    return orderIndex;
    }

    public void setOrderIndex(Integer orderIndex) {
    this.orderIndex = orderIndex;
    }

    public Integer getParentId() {
    return parentId;
    }

    public void setParentId(Integer parentId) {
    this.parentId = parentId;
    }

    public void setZtreeNodes(String ztreeNodes) {
    this.ztreeNodes = ztreeNodes == null ? null : ztreeNodes.trim();
    }

    public String getZtreeNodes() {
    return ztreeNodes;
    }

}

4.SweetAlert插件简介

SweetAlert是一款不需要jQuery支持的原生js提示框，风格类似bootstrap。它的提示框不仅美丽动人，并且允许自定义，支持设置提示框标题、提示类型、内容展示图片、确认取消按钮文本、点击后回调函数等。

官网地址：http://demo.sc.chinaz.com/Files/DownLoad/webjs1/201410/jiaoben2855/

SweetAlert相关API：

参数	描述
title	提示框标题
text	提示内容
type	提示类型，有：success（成功），error（错误），warning（警告），input（输入）。
showCancelButton	是否显示“取消”按钮。
animation	提示框弹出时的动画效果，如slide-from-top（从顶部滑下）等
html	是否支持html内容。
timer	设置自动关闭提示框时间（毫秒）。
showConfirmButton	是否显示确定按钮。
confirmButtonText	定义确定按钮文本内容。
imageUrl	定义弹出框中的图片地址。

5.SweetAlert警示框实例

⑴ 引入SweetAlert的js和css文件：

<script type="text/javascript" src="/assets/scripts/jquery-1.8.2.min.js"></script>
<script type="text/javascript" src="/assets/scripts/sweet-alert.min.js"></script>
<link rel="stylesheet" type="text/css" href="/assets/styles/sweet-alert.css"/>

⑵ js调用SweetAlert插件：

swal({
       title:"提示",
       text:"您确定要删除此角色吗？",
       type:"warning",
       showCancelButton:"true",
       showConfirmButton:"true",
       confirmButtonText:"确定",
       cancelButtonText:"取消",
       animation:"slide-from-top"
     }, function() {
        $.ajax({
            type : "GET",
            url : "../api/deleteRole?id=1"
        }).done(function(msg) {
           if(msg=="success"){
                swal("操作成功!", "已成功删除数据！", "success");
           }else{
                swal("操作失败!", "该角色已关联到组，请先将其移除组！", "warning");
           }
                window.location.href = "roleList?roleType=1";
           }).error(function() {
                swal("OMG", "删除操作失败了!", "error");
        });
});
