Question

extjs 如何单击下让GridPanel里某一行的复选框选中

Answer 1

var sm = new Ext.grid.CheckboxSelectionModel({
//singleSelect: true,
listeners:{
//选中
"rowselect": function (grid,rowIndex,e) {
//使用这种方法会在先点击最后一组数据的时候报错
//var row=grid.getSelections();
//var val=row[rowIndex].get("id");

var grid = Ext.getCmp("shopGrid");
var val = grid.getStore().getAt(rowIndex).get("id");
sendUsersId.push(val);//存放用户id
//alert(sendUsersId.toString());
},
//取消选中
"rowdeselect": function (grid, rowIndex, e) {
var grid = Ext.getCmp("shopGrid");
var val=grid.getStore().getAt(rowIndex).get("id");
sendUsersId.remove(val);//移除用户id
//alert(sendUsersId.toString());
}
}
});
