EasyUI Tree与Datagrid联动

 

1. 效果图

这是一个简单的solr检索的例子

 

输入关键词,显示树

 

选择一个节点,得到该节点下文档信息

 

1. 代码:

JSP:

重点是标红的URL传递

<body>

    <div
class="easyui-panel"
title="Solr">

        <div
style="padding: 10px 60px 20px 60px;">

            <table
cellpadding="5"
align="center">

                <tr>

                    <td>Carrot2:</td>

                    <td><input
class="easyui-validatebox textbox"
type="text"

                        name="q"
data-options="required:true"></input></td>

                    <td><a
href="javascript:void(0)"
class="easyui-linkbutton"

                        onclick="submitForm()">Search</a></td>

                </tr>

            </table>

        </div>

    </div>

    <br />

    <table>

        <tr>

            <td>

                <div
class="easyui-panel"

                    style="padding: 5px; width: 400px; height: 600px;">

                    <ul
id="cluster_tree"
class="easyui-tree"></ul>

                </div>

            </td>

            <td>

                <div
class="easyui-panel"

                    style="padding: 5px; width: 1160px; height: 600px;">

                    <table
id="docs"></table>

                </div>

            </td>

        </tr>

    </table>

    <script>

        function submitForm() {

            $('#cluster_tree').tree(

                    {

                        url : 'tree.do/' + $("input[name='q']").val(),

                        method : 'GET',

                        onClick : function(node) {

                            $('#docs').datagrid(

                                    {

                                        url : 'docs.do/' + node.id + '/'

                                                + $("input[name='q']").val(),

                                        method : 'GET',

                                        width : 'auto',

                                        striped : true,

                                        singleSelect : true,

                                        loadMsg : '数据加载中请稍后……',

                                        rownumbers : true,

                                        columns : [ [ {

                                            field : 'name',

                                            title : '文档编号',

                                            align : 'center'

                                        }, {

                                            field : 'title',

                                            title : '文档名称',

                                            align : 'left'

                                        }, {

                                            field : 'score',

                                            title : '得分',

                                            align : 'left'

                                        } ] ]

                                    });

                        }

                    });

        }

    </script>

</body>

 

JAVA:

这里只提供接口级别的定义

    /**

     * 得到聚类树

     * @param q     检索的字段

     * @return        使用JSONArray生成JSON

     * @throws SolrServerException

     */

    @RequestMapping(value = "tree.do/{q}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)

    @ResponseBody

    public String getTreeList(@PathVariable String q) throws SolrServerException

    {}

 

    /**

     * 得到文档列表

     * @param name     文档的ID

     * @param q     检索的字段,再检索

     * @return        使用JSONArray生成JSON

     * @throws SolrServerException

     */

    @RequestMapping(value = "docs.do/{name}/{q}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)

    @ResponseBody

    public String getDocList(@PathVariable String name, @PathVariable String q) throws SolrServerException

    {}

 

1. 总结:

   需要注意的是,这里虽然使用检索获得Tree,但是并没有采用POST表单的方式得到Tree的数据而是使用GET+参数方式获得.

   EasyUI使的不多,感觉这方面的资料比较少,如果有更好的实现方式请告诉我,谢谢!
