Ext中Store数据的操作【添加统计行】

var deletelist="";

var addauthlist="";

var addeditlist="";

var adddownloadlist="";

var rowCount = Ext.getCmp("authgrid").store.getCount();

for (var i = 0;i < rowCount; i++) {

var record = Ext.getCmp('authgrid').getStore().getAt(i);

//删除

if (record.data.auth ==
'0' && record.data.authid !=
""){

deletelist +=record.data.authid + ',';

} if (record.data.edit ==
'0'&& record.data.editid !=
"") {

deletelist +=record.data.editid + ',';

} if (record.data.download ==
'0'&& record.data.downloadid.downloadid !=
""){

deletelist +=record.data.downloadid +
',';

}

//添加

if (record.data.authid ==
"" && record.data.auth ==
'1') {

addauthlist +=record.data.guid + ',';

}if (record.data.editid ==
""&& record.data.edit ==
'1') {

addeditlist +=record.data.guid + ',';

}if (record.data.downloadid ==
""&& record.data.download ==
'1') {

adddownloadlist +=record.data.guid +
',';

}

}

添加合计行

gridstore.load({params: { start: 0, limit: pageSize }, callback:
function() { amountsum(); } });
@*-----------合计-----------*@

<script>

function amountsum(){

//var rowCount =Ext.getCmp("financepaymentgrid").store.getCount();

varrowCount = gridstore.getCount();

var p =
newExt.data.Record({ fields: ['id',
'cmp_id',

'amount',

'difference',
'statename',

'paymnet_acc_time',
'paymnet_last_verifi_time',
'paymnet_final_verifi_time',
'pay_appointed_day',
'gen_id'] });//定义一行要插入的record

var amount= 0, verification = 0, difference = 0;

gridstore.each(function (record) {

if(record.data.amount !=
null) {
amount +=Number(record.data.amount);//叠加需要合计的列值返回给sum

}

if(record.data.verification !=
null) {
verification +=Number(record.data.verification);//叠加需要合计的列值返回给sum

}

if(record.data.difference !=
null) {
difference +=Number(record.data.difference);//叠加需要合计的列值返回给sum

}

});

//Ext.getCmp('financepaymentgrid').store.each(function(record) {

// amount += Number(record.data.amount);//叠加需要合计的列值返回给sum

// }

//});
