ExtJs4之Grid详细

ExtJs博客前奏

由于这段时间事情比较杂乱,博客就主要以项目中例子来说明编写。

ExtJs4中的Grid非常强大,有展示,选中,搜索,排序,编辑,拖拽等基本功能,这篇博客我就这几个功能做写累述。

1.ExtJs4之Grid详细

2.ExtJs4之TreePanel

<script type="text/javascript">
        Ext.onReady(function () {

function showAlert (){
var selectedData=grid.getSelectionModel().getSelection()[0].data;

Ext.MessageBox.alert("标题",selectedData.cataId);
}
}); 
</script>

注释:

一、gridPanel几个必须配置的项:store(数据格式组织、存储),columns(展示到页面的格式,数据组织)。

      1、store里面有个fields配置,为需要的数据字段,跟读取到的数据(本地,或远程获取的)字段对应。

      2、columns中的text为grid展示的列标题,dataIndex绑定字段与store中fields配置字段的对应。

二、数据获取

 proxy: {
                    type: 'ajax',
                    url: '/Tools/106.ashx?method=getAllCatalog',
                    reader: {   //这里的reader为数据存储组织的地方,下面的配置是为json格式的数据,例如:[{"total":50,"rows":[{"a":"3","b":"4"}]}]
                        type: 'json', //返回数据类型为json格式
                        root: 'rows',  //数据
                        totalProperty: 'total' //数据总条数
                    }
                },
                sorters: [{
                    //排序字段。
                    property: 'ordeId',
                    //排序类型,默认为 ASC 
                    direction: 'desc'
                }],
View Code

     1、传递的参数为:method=getAllCatalog&page=1&start=0&limit=20&sort=[{"property":"ordeId","direction":"desc"}]

     2、传回数据为:{"rows":[{"rowNum":"1","cataId":"852","cataNo":"10000809","cataTitle":"","cataObject":"4","cataObjectName":"华悦购物","cataType":"1","cataTypeName":"默认","cataeditstatus":"2","cataeditstatusName":"待提交","cataPublishStatus":"2","cataPublishName":"已发布","cataRemark":"banner广告","cataObjectType":"2","apptypename":"销售","cataEndDate":"2014-09-27","holyCreateTime":"2013-11-24 16:02:04","holyUpdateTime":"","catapushtime":"","holyCreateUser":"lhcs"}]}

三、分页(不带搜索条件):         

bbar: [{
                xtype: 'pagingtoolbar',
                store: store,
                displayMsg: '显示 {0} - {1} 条,共计 {2} 条',
                emptyMsg: "没有数据",
                beforePageText: "当前页",
                afterPageText: "共{0}页",
                displayInfo: true                 
            }]
View Code

        1、store为grid的store

        2、store中的remoteSort配置为true。

        3、传递参数为:你点的列标题绑定字段+desc/asc,组织格式为:method=getAllCatalog&page=1&start=0&limit=20&sort:[{"property":"cataNo","direction":"DESC"}]

四、选中行

       1、选中行点击事件

  listeners: { 'itemclick': function (view, record, item, index, e) {
               Ext.MessageBox.alert("标题",record.data.cataId);
            }
View Code

       2、外部操作选中行       

 function showAlert (){
             var selectedData=grid.getSelectionModel().getSelection()[0].data;
             Ext.MessageBox.alert("标题",selectedData.cataId);
         }
View Code

       3、外部操作多行选中

  var rows = grid.getView().getSelectionModel().getSelection();
                var msg = "";
                for (var i = 0; i < rows.length; i++) {
                    msg = msg + rows[i].get('cataId') + ',';
                }
View Code

五、列数据格式

  1、时间
{ text: '发布时间', dataIndex: 'catapushtime',xtype:'datecolumn',dateFormat :'Y-m-d H:i:s'}
View Code

     2、金钱

{ text: '订单金额', dataIndex: 'oprice',align:'right', xtype:'numbercolumn',format:'0,000.00'},
View Code

     3、多字段组合

   { text: '毛利率', dataIndex: 'sPrice', minWidth: 20,
                                renderer: function(v, m, r){
                                var puprsaleprice = r.get("sPrice") * r.get("puprsalepricetax")/(1+r.get("puprsalepricetax"));
                                var puprtaxprice = r.get("cPrice") * r.get("puprtax")/(1+r.get("puprtax")); 
                                //var maoprice = (r.get("sprice") - r.get("cprice") - (puprsaleprice-puprtaxprice)- r.get("puprinvoiceprice") - r.get("pfreight") - r.get("sprice") * r.get("fpoint"))/r.get("sprice");    
                                var maoprice = (r.get("sPrice") - r.get("cPrice") - (puprsaleprice-puprtaxprice)- r.get("puprinvoiceprice") - r.get("pfreight") - r.get("sPrice") * r.get("fpoint"))/(r.get("sPrice") / (1+r.get("puprsalepricetax")));                
                                return (maoprice * 100).toFixed(2) + '%';
                            }},
View Code

 六、Grid数据刷新

  1、不传参刷新当前数据
store.load();
View Code

     2、传参刷新数据

store.load({ params: { Id: 123} });
View Code

Grid编辑

注释:

1、标记变色

{
                                header: "名称",
                                width: 200,
                                dataIndex: 'prodNameZh',
                                align: 'left',
                                renderer: function (value, metaData, record) {//自定义列值组合
                                    var path = record.get("prcaImg");
                                    var txt = value;
                                    if (path != "" && path != null) {
                                        txt = '<span style="color:blue;display:table;width:100%;" qtip=\'<img width="280" src="upload/'
                                                 + path.charAt(0) + "/" + path + '">\'>' + txt + '</span>';
                                    }
                                    return txt;
                                },
                                sortable: true
                            },

2、Grid行tip提示

   catalogEditProduct.getView().on("render",function(view){  
                view.tip=Ext.create('Ext.tip.ToolTip',{  
                    target:view.el,  
                    delegate:view.itemSelector,  
                    trackMouse:true,  
                    renderTo:Ext.getBody(),  
                    listeners:{  
                       beforeshow:function(tip){  
                           var record=view.getRecord(tip.triggerElement);  
                           var ucc=record.get("prcaImg").substring(0,1);                          
                           var html="<div ><img width='300px'  src='/upload/"+ucc+"/"+record.get("prcaImg")+"'></div>";  
                           tip.update(html);
                       }  
                    }  
      
                });  
            });  
View Code

附图:

3、Grid行编辑

 var RowEditing = Ext.create('Ext.grid.plugin.RowEditing', { // 行编辑模式
                        clicksToMoveEditor : 2,   //双击编辑  整行修改
                        autoCancel : false,
                        saveBtnText:'确定',
                        cancelBtnText:'取消',
                        errorsText:'错误',
                        dirtyText:'你要确认或取消更改'
                       
            });
View Code

首先上面那段代码加上,然后columns里面配置editor(详见上面代码),最后在 Grid中配置plugins : [RowEditing]。。

 

 

grid就先整理这么多,下一篇预告为:TreePanel。。I hope it'll help you , Thanks for reading..
