后台控制 gridpanel中CheckboxSelectionModel 是否勾选怎么写

你在sotre里加一个selected列，如果要选中在后台把它设置用true
如
{deptname:'aa',carkindsname:'bb',selected:true}
var sm = new ext.grid.checkboxselectionmodel();var cm = new ext.grid.columnmodel([sm, {align : 'center',header : "车属单位",dataindex : "deptname",renderer : zeroornull}, {align : 'center',header : "车种名",dataindex : "carkindsname",renderer : zeroornull}])grid.store.on('load', function(store, records, options) {sm.clearselections();ext.each(records, function(rec) {if (rec.get('selected')) {sm.selectrow(grid.store.indexofid(id),true);}})});
