參考範例從中取下一段 用在column中 沒啥好說的,都跟範例一樣 { xtype: 'actioncolumn', items: [ { getClass: function(v, meta, eric) { // Or return a class from a function if (eric.get('change') < 0) { this.items[0].tooltip = 'Do not buy!'; return 'approved_changes_3'; } else { this.items[0].tooltip = 'Buy stock'; return 'summary_duetoday_5'; } }, handler: function(grid, rowIndex, colIndex) { var eric = store.getAt(rowIndex); //window.open("http://192.168.3.1/sayhi.html"); //setTimeout("alert('hi'+eric.get('company'));" , 100); alert('hi '+eric.get('company'));
