EasyUI DataGrid中loadFilter 属性的用法

来源：互联网发布：js 向数组添加对象编辑：程序博客网时间：2024/04/27 06:45

DataGrid属性中有一个用于过滤数据的属性loadFilter

可以根据需求进行过滤，示例如下：

$('#dg_fc').datagrid({
fit : true,
method : 'post',
url : rootPath + 'overdue_query_list.xhtml',
rownumbers : true,
toolbar :'#toolbar_fc', //指定toolbar
singleSelect : true,
nowrap : true,
striped : true,
remoteSort :false,
pagination : true,
pageSize : 15,
pageList : [5,10,15,20,25,30,35,40,45,50],
frozenColumns:[[{field:'id', checkbox:true}]],
columns : columns_fc,
loadFilter : function(data){
//过滤数据
var value={
total:data.total,
rows:[]
};
var x=0;
for (var i = 0; i < data.rows.length; i++) {
if(data.rows[i].tranModel.productType=="01"){
value.rows[x++]=data.rows[i];

}
}
return value;
},
onLoadSuccess : function() {
//在数据加载成功的时候触发
$('#dg_fc').datagrid('clearChecked');
$("#dg_fc").datagrid('tooltip'); //数据过长会浮动显示
}

}};

中：

loadFilter : function(data){
//过滤数据
var value={
total:data.total,
rows:[]
};
var x=0;
for (var i = 0; i < data.rows.length; i++) {
if(data.rows[i].tranModel.productType=="01"){
value.rows[x++]=data.rows[i];

}
}
return value;
}

可以使用自己逻辑进行过滤数据，用于在data中展示。

原数据如下：

{
"total": 1,
"rows": [
{
"tid": "30",
"name": "小四",
"no": "500240198408085770",
"surplusamount": null,
"maxamount": null,
"creditpoint": null,
"phone": "12300000000",
"tranModel": {
"id": 30,
"userId": 1,
"state": 8,
"errorMsg": null,
"loanInitRate": 0.0005,
"loanRealRate": 0.0005,
"loanInitManageRate": 0.001333,
"loanRealManageRate": 0.001333,
"loanReceipts": "tjk012016011500006",
"transReceipts": "075598712016000000027-013",
"loanPrincipal": 1000,
"loanDate": 1452443160000,
"planRepayDays": 7,
"planRepayDate": 1452960000000,
"planRepayInterest": 54.99,
"planRepayAccrual": 15,
"planRepayFee": 39.99,
"planRepayAmount": 1054.99,
"fixThirdpartyCost": 2,
"loanSysCardID": 1,
"loanUserCardID": 1,
"reviewDate": 1452788760000,
"reviewSysUser": 9999,
"transferDate": 1452443160000,
"transferSysUser": 9999,
"leftAmount": 1000,
"leftRepayInterest": 0,
"realRepayDate": null,
"realRepayDays": 9,
"realRepayInterest": null,
"realRepayAccrual": null,
"realRepayFee": null,
"realRepayOverDueAccrual": null,
"realRepayOverDueFee": null,
"realRepayAmount": null,
"realRepayPrincipal": null,
"realThirdpartyCost": null,
"repaySysCardID": null,
"failCause": null,
"contractSignature": "",
"contractState": 1,
"oldState": null,
"repayReceipts": null,
"discountAmount": 0,
"discountType": null,
"couponNo": null,
"comments": null,
"version": 1,
"productType": "01",
"overdueRate": 0.0002,
"overdueManageRate": 0.0005332,
"phasedNums": null,
"repayTimes": 0,
"isLoanNormCheck": 1,
"illegalUseAdd": null,
"overDueAdd": null,
"iVersion": 2,
"thirdpartyRepayFeeRate": null
},
"bankCard": "中国银行尾号0000",
"bankCode": 3,
"accountNo": "6212480000000000",
"msgCount": null,
"apartDay": null,
"loanPoundage": 54.99,
"overdueAmount": 5.13,
"overdueDay": 3,
"bankName": "中国银行",
"prmList": null,
"reviewSysUserStr": null,
"apartDayFQ": null,
"currentTime": null
}
]
}

该例子中以字段json中productType进行过滤，返回满足条件的数据，去除不符合条件数据。

注意:这个函数必须返回包含'total'和'rows'属性的标准数据对象。
