Ext grid

1. grid 添加行点击事件
 grid.addListener('cellclick',function(grid,rowIndex,columnIndex,e){
    if(columnIndex== 1){
    varrecord = grid.getStore().getAt(rowIndex).data;
    AddWin(record,1);
   }
  
 }); 

2. grid 添加右键功能
grid.on('rowcontextmenu',function(grid,index,e){
     var data =grid.getStore().getAt(index).data;
    
   varfirstLegal = {
            text: '一one',
            handler : function(){
                           }
        };
        
        var firstIllegal = {
            text: '一two',
            handler : function(){
                           }
        };
        
        var secondLegal = {
            text: '二one',
            handler : function(){
                           }
        };
        
        var secondIllegal = {
            text: '二two',
            handler : function(){
            }
        };
        
  
             menu = new Ext.menu.Menu([
     secondLegal,
     secondIllegal,
     '-'
   ]);
   menu.showAt(e.getPoint());
     
     // 阻止浏览器弹出右键餐单
     e.preventDefault();
  });
 
3. //再Grid 中添加展开行
 var expander = new Ext.grid.RowExpander({
tpl: new Ext.Template('<divstyle="padding-left:45px;font-size:12px;"><br><p><b&gt;描述:</b><br/>{programmeIntro}</p><b</div>')
});

4.
  var store = newExt.data.JsonStore({
    root:'root',
    totalProperty:'sum',
    url:'url',
    remoteSort:true,
    
    fields:[
     {name: 'name' , mapping: 'name' },
     {name: 'num' , mapping: 'num' }
    ]
   });
   
   store.setDefaultSort('num','DESC');
   store.on('beforeload',function(store, options){
      options.params = Ext.apply(options.params,{
       method: 'grid',
       taskId:Ext.getDom('taskId').value
      });
     });

   varpagingBar = new Ext.PagingToolbar({
    pageSize:50,
    store:store,
    displayInfo:true,
    emptyMsg:'没数据',
    items:['-',
     {text: '' },'-',
     '<divid=""></div>',
     '<divid=""></div>'
    ]
   });
  
   
   var sm = newExt.grid.CheckboxSelectionModel();

 

3. 分页变序号
   Ext.grid.PagedRowNumberer = function(config){
    Ext.apply(this, config);
    if(this.rowspan){
        this.renderer = this.renderer.createDelegate(this);
    }
  };
  
  Ext.grid.PagedRowNumberer.prototype= {
     width:20,
     sortable:false,
     fixed:false,
     hideable:false,
     rowspan: undefined,
     
     renderer : function(v, p, record, rowIndex, colIndex, store){
         if(this.rowspan){
             p.cellAttr = 'rowspan="'+this.rowspan+'"';
         }
         var i = store.lastOptions.params.start;
         if (isNaN(i)) {
             i = 0;
         }
         i = i + rowIndex + 1;
         i = Number(i).toString();
         return i;
     }
  };

4.  改变行高
renderer:function(value,p,record){
 return '<divstyle="height:15px">'+ value +'</div>';
}
