示例:

Ext.onReady(function() {
var testData = [
['1','xxxxx'],
['2','aaaa'],
['3','xxyyy'],
['4','bbbb']
];

var selectValue = ['bbbb','aaaa']

var store = new Ext.data.SimpleStore({
  fields:['id','name']
});

var sm = new Ext.grid.RowSelectionModel({
listeners:{
'rowselect':function(sm,rowIndex,r){
Ext.log("select",rowIndex,r.get('name'))
}
}
});
var grid = new Ext.grid.GridPanel({
width: 800,
height: 500,
autoScroll: true,
store: store,
sm:sm,
columns: [
sm,
{ header: '序号', dataIndex: 'id', sortable: true },
{ header: '名字', dataIndex: 'name', sortable: true }
]
});
var v = new Ext.Viewport({
items:[grid]
});
store.on('load',function(store,records,options){
var arr=[];
for(var i=0;i<records.length;i++){
var record = records[i];
var isMatch = selectValue.indexOf(record.get('name'))!=-1;
if(isMatch){
arr.push(record);
}
}
sm.selectRecords(arr);
},this,{delay:1000})
store.loadData(testData);
