实现Easyui 可编辑表格

一.前端框架使用的easyui框架

二.后端使用的是jfinal

三.效果图

四.html代码

<div id="table_tree" class="easyui-panel" id="div_panel" style="550px;height:350px;padding-top:5px;overflow:auto;" data-options="border:false"> 
      <table class="easyui-treegrid" id="dg"
                data-options="border:false">
            <thead>
                <tr>
                    <th data-options="field:'name',formatter:checkShow"  width="280">
                        <font class="my-datagrid-header">资产名称</font>
                    </th>
                    <th data-options="field:'targetName',editor:{type:'textbox',options:{required:true,validType:'length[1,30]'}}"  width="280">
                        <font class="my-datagrid-header">创建的目标资产名称</font>
                    </th>
                </tr>
            </thead>
        </table> 
</div>
<script type="text/javascript">
function checkShow(value,rowData,rowIndex){
      if(rowData.parent == Globals.Prop.treeRoot){
           return "<input name='tableCheck' type='checkbox' value='"+rowData.id+"'>" + rowData.name;
      }else if(rowData.id == Globals.Prop.treeRoot){
          return "<input name='tableCheckAll' type='checkbox' value='"+rowData.id+"'>" + rowData.name;
      }else{
          return rowData.name;
      }
}
注意：editor:{type:'textbox',options:{required:true,validType:'length[1,30]'}}表示targerName验证规则，长度不能超过30个字符

 五.js代码

var createTable = {};
createTable.editIndex = undefined;//编辑index
//渲染源链接表和字段资产信息（treegrid）
    createTable.two_tableTree = function(data){
        createTable.dg = $("#dg");
        createTable.dg.treegrid({
            idField: 'id',
            treeField: 'name',
            singleSelect: false
        });
        var gridProp = {
                data:data,
                '550px',
                height:'320px',
                pagination:false,//显示分页  
                loadFilter: function(data){
                    return data.pageRow;
                },
                onBeforeExpand: function(row){
                    //点击表名时，加载字段信息 如果row.state = open 说明字段信息已从服务器获取到，不会重复加载数据
                    if(row.parent == 'ROOT'){
                         createTable.dg.treegrid('options').url = Globals.Prop.contextPath + "/meta/import/findColumn.bs";
                    }
                    return true;
                },
                onClickCell:function(field,row){
                    //点击触发编辑表格
                    createTable.onClickCell(row.id, field);
                },
                onLoadSuccess:function(data){
                     //折叠 unselectAll
                    createTable.dg.treegrid('unselectAll');
                    //createTable.dg.treegrid('collapseAll',Globals.Prop.treeRoot);
                    //createTable.dg.treegrid('expand',Globals.Prop.treeRoot);
                    checkAll();
                }
            };
         createTable.dg.treegrid(gridProp);
         //当treegrid height:0px时，处理
         $(".datagrid").find(".datagrid-view2 .datagrid-header").css("height","25px");
         $(".datagrid").find(".datagrid-view2 .datagrid-htable").css("height","25px");
         $(".datagrid").find(".datagrid-view").css("height","330px");
         $("#table_tree").find(".datagrid-body").css("overflow-x","auto");
        
         //全选或反选
         function checkAll(){
             $("input[name='tableCheckAll']").click(function(){
                 var check = $(this).is(":checked");
                 if(!check){
                     createTable.dg.treegrid('unselectAll');
                 }
                 $("input[name='tableCheck']").each(function(){
                     if(check){
                         createTable.dg.treegrid('select',$(this).val());
                     }
                     $(this).prop("checked",check);
                 })
             })
         }
    }
    
    createTable.endEditing = function(){
        if (createTable.editIndex == undefined){return true};
        if (createTable.dg.datagrid('validateRow', createTable.editIndex)){
            createTable.dg.datagrid('endEdit', createTable.editIndex);
            createTable.editIndex = undefined;
            return true;
        } else {
            return false;
        }
    }
    
    /**
     * index:行位置
     * field:字段名称
     * 当选中一行,某字段时触发
     */
    createTable.onClickCell = function(index, field){
        if (createTable.editIndex != index){
            if (createTable.endEditing()){
                if(field == "name" || index == "root") return;
                createTable.dg.treegrid('selectRow', index)
                        .treegrid('beginEdit', index);
                var ed = createTable.dg.treegrid('getEditor',{index:index,field:field});
                if (ed){
                    ($(ed.target).data('textbox') ? $(ed.target).textbox('textbox') : $(ed.target)).focus();
                }
                createTable.editIndex = index;
            } else {
                if (createTable.editIndex == undefined){return};
                createTable.dg.treegrid('selectRow', createTable.editIndex);
            }
        }
    }

六：后台实现
     1> sql    

select 'ROOT' id, '' parent,'test' name,'test' targetName, 'icon-userSchema' iconCls,'open' state,'' label from dual  
      union all  
      select t.id, 'ROOT' parent, t.name, t.name targetName, 'icon-table' iconCls,'closed' state,label   from dmm_meta_table t  where t.schema = ''

      2>实现方法    

List<Record> records = api.find(sql());
List<TableTree> tables = BsModelPropAdapter.adapterList(records, TableTree.class);

       3>model

public class TableTree implements Serializable {

    private static final long serialVersionUID = 1L;
    
    private String id = ID.get();
    
    private String name;
    
    private String targetName;
    
    private String parent;
    
    private String state;
    
    private String label;

    public String getLabel() {
        return label;
    }

    public void setLabel(String label) {
        this.label = label;
    }

    public String getState() {
        return state;
    }

    public void setState(String state) {
        this.state = state;
    }

    /* easyui TreeGrid 匹配字段 */
    @JSONField(name="_parentId") 
    private String _parentId;
    
    private String iconCls;

    public String getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getParent() {
        return parent;
    }

    public void setParent(String parent) {
        this.parent = parent;
    }

    /* 返回Parent */
    public String get_parentId() {
        return parent;
    }

    public void set_parentId(String _parentId) {
        this._parentId = _parentId;
    }
    public String getTargetName() {
        return targetName;
    }

    public void setTargetName(String targetName) {
        this.targetName = targetName;
    }

    public String getIconCls() {
        return iconCls;
    }

    public void setIconCls(String iconCls) {
        this.iconCls = iconCls;
    }
    
}
