改造的是 http://extjs.com/deploy/ext/docs/index.html Inline editing 这个例子 把数据源换成从数据库取数了，可是界面上显示不出数据来 不知道那里有问题，请，另外顺便在问一句这个例子中 新增加一行记录 怎么把新增加或修改的数据保存到数据库 谢谢
dao里实现如下
public List QueryYhxx(String tj) {
StringBuffer sb =new StringBuffer();
sb.append(" SELECT psuser_uid,psuser_name,psuser_zznm,psuser_cjrq,psuser_cjr ");
sb.append(" From psuser ");

return (List)getJdbcTemplate().query(sb.toString(),new ResultSetExtractor() {
public Object extractData(ResultSet rs)
throws SQLException, DataAccessException {
List lt = new ArrayList();
while (rs.next()) {
test  dbean = new test();
dbean.setBh(rs.getString("psuser_uid"));
dbean.setXm(rs.getString("psuser_name"));
dbean.setTel(rs.getString("psuser_zznm"));
dbean.setAdd(rs.getString("psuser_cjrq"));

lt.add(dbean);
}
return lt;
}
});
}

action 里实现如下
public String getGridJsonData1(ActionForm form,HttpServletRequest request,HttpServletResponse response) throws IOException{
List list=this.getService().QueryYhxx("");
System.out.println("test");
//JSONArray jsonArray = JSONArray.fromObject(list);
//不知道该用  JSONArray.fromObject 还是用 JSONArray.fromCollection((Collection) list) 好象结果是一样的
//System.out.println("test:"+jsonArray.length());
//System.out.println("test:"+jsonArray.toString());

String json=JSONArray.fromCollection((Collection) list).toString();

System.out.println("test:"+json);

response.setContentType("text/html;charset=UTF-8");
response.getWriter().print("{datalist:" + json + "}");

return null;
}

System输出的数据如下:
[{"add":"20070621  ","xm":"test","bh":"001","tel":"山东省组织部","cj":0}]

页面显示数据脚本如下
Ext.onReady(function(){



    function formatBoolean(value){

    };
   
    function formatDate(value){
        return value ? value.dateFormat('M d, Y') : '';

    // shorthand alias
    var fm = Ext.form, Ed = Ext.grid.GridEditor;

    // the column model has information about grid columns
    // dataIndex maps the column to the specific data field in
    // the data store (created below)
    var cm = new Ext.grid.ColumnModel([{

    // by default columns are sortable
    cm.defaultSortable = true;

    // this could be inline, but we want to define the Plant record
    // type so we can add records dynamically
    var Plant = Ext.data.Record.create([
           // the "name" below matches the tag name to read, except "availDate"
           // which is mapped to the tag "availability"
           {name: 'bh', type: 'string'},
           {name: 'xm', type: 'string'},
           {name: 'tel',type: 'string'},
           {name: 'add', type: 'string'}
      ]);

    // create the Data Store
    var ds = new Ext.data.Store({
        // load using HTTP
        proxy: new Ext.data.HttpProxy({url: '/plat/qmys/test/test.do?cmd=getGridJsonData1'}),

    });

    // create the editor grid
    var grid = new Ext.grid.EditorGrid('editor-grid', {
        ds: ds,
        cm: cm,
        //selModel: new Ext.grid.RowSelectionModel(),
        enableColLock:false
    });

    var layout = Ext.BorderLayout.create({
        center: {
            margins:{left:3,top:3,right:3,bottom:3},
            panels: [new Ext.GridPanel(grid)]
        }
    }, 'grid-panel');


    // render it
    grid.render();

   
    var gridHead = grid.getView().getHeaderPanel(true);
    var tb = new Ext.Toolbar(gridHead, [{
        text: '增加',
        handler : function(){
            var p = new Plant({
                bh: 'BH',
                xm: 'XM',
                tel: 'TEL',
                add: 'ADD'
            });
            grid.stopEditing();
            ds.insert(0, p);
            grid.startEditing(0, 0);
        }
    }]);
tb.add('-',
{
text: '修改',
handler :  modify
},
'-',
{
text: '保存',
handler :  savedata
}

)
function modify(){
alert("modify");
}
function savedata(){

}
    // trigger the data store load
    ds.load();
});

发帖也需要责任心

[{"add":"20070621 ","xm":"test","bh":"001","tel":"山东省组织部","cj":0}]

格式不对吧 引号

可以去jstang论坛看看入门例子


api文档上些得还是比较清楚的吧 建议看看javaeye发帖的规则

数据已经显示出来了，现在不知道在页面上新增加的行或修改的数据，如何传到 action ,action 里面如何解析，请，谢谢

向 ksgimi 表示敬意.你写的示例代码非常好.把问题说到点子上了.我也遇到了同样的问题:ds.getModifiedRecords()中竟然不包括新增的记录,使用你那个办法基本可以解决这个问题.我希望未来能将ExtGrd用到Delphi数据感知组件的那种程度:不但能自动显示出数据,而且能自动收集修改过的数据(包括增删改),然后将修改过的数据提交到后台,后台就能自动生成 相应的更新数据Sql语句.这样就能做到在具体的业务逻辑之上实现数据的 CRUD (增删改查).那就爽了.

补充一点:
在 ksgimi 代码的基础上加一行:
ds.getAt(yetCount).set("name",'未命名');  
ds.getAt(yetCount).IsNew = true; //增加一个自定义属性,表明这是一条新增的记录.
这样就能可靠地得知哪些记录是新增的.

有共同语言，集成buffalo extjs,但没有必要考虑struts
