我正在使用jgGrid绑定从Web服务收到的JSON响应。 我面临排序功能的2个问题 -
1.网格中的数据最初不会使用提供的参数进行排序 -
sortname: "BankName",
sortorder: "asc",
2.列上不显示排序图标。点击列标题都不适合我。
收到的JSON数据:
[{"Id":1,"BankId":2,"BankName":"State bank","EmployeeId":2539,"EmployeeName":"John C.","JoiningDate":"2005-07-05T00:00:00","SalaryAmount":50000.0,"Comments":""},
{"Id":2,"BankId":2,"BankName":"State bank","EmployeeId":2232,"EmployeeName":"xxx","JoiningDate":"2001-12-23T00:00:00","SalaryAmount":30000.0,"Comments":"test"},
{"Id":3,"BankId":4,"BankName":"National bank","EmployeeId":2322,"EmployeeName":"yyyy","JoiningDate":"2002-09-23T00:00:00","SalaryAmount":90000.0,"Comments":""},
{"Id":4,"BankId":3,"BankName":"Punjab bank","EmployeeId":2432,"EmployeeName":"ppp","JoiningDate":"2003-01-31T00:00:00","SalaryAmount":60000.0,"Comments":" "},
{"Id":5,"BankId":1,"BankName":"Bank of Maharashtra","EmployeeId":2892,"EmployeeName":"zzz y.","JoiningDate":"2000-10-11T00:00:00","SalaryAmount":80000.0,"Comments":"test 2"}
]
jqGrid声明和绑定:
<script type="text/javascript">
jQuery(document).ready(function () {
jQuery("#employeeSalarysGrid").jqGrid({
height: 250,
url: 'http://localhost:50570/api/Test/GetEmployeeSalaries',
mtype: "GET",
contentType: "application/json; charset=utf-8",
datatype: "json",
serializeGridData: function (postData) {
return JSON.stringify(postData);
},
jsonReader: {
root: function (obj) { return obj; },
page: function (obj) { return 1; },
total: function (obj) { return 1; },
records: function (obj) { return obj.length; },
id: "0",
cell: "",
repeatitems: false
},
datatype: "json",
colNames: ['Id', 'Bank Name', 'Employee name', 'Joining date', 'Salary amount', 'Comments'],
colModel: [
{ name: 'Id', index: 'Id', align: "center", key: true },
{ name: 'BankName', index: 'BankName', align: "center" },
{ name: 'EmployeeName', index: 'EmployeeName', align: "center" },
{ name: 'JoiningDate', index: 'JoiningDate', align: "center" },
{ name: 'SalaryAmount', index: 'SalaryAmount', align: "center" },
{ name: 'Comments ', index: 'Comments', align: "center" }
],
sortname: "BankName",
sortorder: "asc",
viewrecords: true,
rowNum: 10,
rowList: [10, 15, 20],
pager: '#employeeSalarysPager',
caption: "Employee Salary list"
});
});
</script>
另请注意,这些是我添加到页面的5个文件:
<link href="../Content/jquery.jqGrid/ui.jqgrid.css" rel="stylesheet" />
<link href="../Content/jquery.jqGrid/jquery-ui-custom.css" rel="stylesheet" />
<script src="../Scripts/jquery-1.9.1.min.js"></script>
<script src="../Scripts/jquery.jqGrid.js"></script>
<script src="../Scripts/i18n/grid.locale-en.js"></script>
请帮我弄清楚为什么排序不起作用。
先谢谢,我真的很感谢你的帮助。

答案 0 :(得分:0)
如果您使用datatype: "json"
,那么服务器会将选项sortname: "BankName"
和sortorder: "asc"
中的参数作为sidx
(排序索引)和{{ 1}}(排序方向)。所以服务器负责至少对返回数据进行初始排序。
我建议您添加sord
选项,这意味着您一次从服务器加载所有数据(不只是10行数据,请参阅loadonce: true
选项)没有实现服务器端数据分页。所以服务器只需要进行初始数据排序。 jqGrid会将所有数据保存在内部参数rowNum: 10
和data
中。在第一次加载数据后,它会将_index
从datatype
更改为"json"
。因此,所有以后的分页,排序,过滤(请参阅filterToolbar)或搜索(请参阅here或here)数据都将在客户端实施 。因此,您需要编写最少的JavaScript代码才能获得所需的功能。
其他我建议您从网址中删除"local"
前缀,从http://localhost:50570
的所有项目中移除index
个属性,添加colModel
和gridview: true
选项,考虑使用autoencode: true
和ignoreCase: true
(而不是您当前使用的height: "auto"
)。
我建议您验证是否使用当前版本的jqGrid(版本4.6.0)。您可以从trirand网站下载当前版本。
