format json date to mm/dd/yy format before display

问题:

I am trying to display some data in a datatable and the table script I am using is

$('#userData').dataTable({

        "ajax": {
                "url": "${rc.getContextPath()}/module/roles/users-list",
                "dataSrc":  "",
                },

        "columns":[
        {"data": "userId"},
        {"data": "applicationId"},
        {"data": "username"},
        {"data": "firstName"},
        {"data": "userCreated"},
        {"data": "createdTime"},
        {"data": "updatedTime"}
        ],

     });

the data that is received by the table is json and would be something like

[
 {  
      "userId":179,
      "applicationId":"pgm-apn",
      "username":"collaborator.user3",
      "password":"password1",
      "email":"[e-mail]",
      "firstName":"Anthony",
      "lastName":"Gonsalves",
      "enabled":true,
      "userCreated":"sitepmadm",
      "userModified":"sitepmadm",
      "createdTime":1422454697373,
      "updatedTime":1422454697373
   },
   {  
      "userId":173,
      "applicationId":"pgm-apn",
      "username":"consumer.user",
      "password":"password1",
      "email":"[e-mail]",
      "firstName":"sherlock ",
      "lastName":"homes",
      "enabled":true,
      "userCreated":"sitepmadm",
      "userModified":"sitepmadm",
      "createdTime":1422010854246,
      "updatedTime":1422010854246
   }

I want to display the dates as proper datetime.Currently it is getting displayed as teh same sting in the json data.Is there any way to convert that in the datatable

回答1:

You can use "render" property to format your column display http://datatables.net/reference/option/columns.render#function.

For example:

{
    "data": "createdTime",
    "render": function (data) {
        var date = new Date(data);
        var month = date.getMonth() + 1;
        return (month.length > 1 ? month : "0" + month) + "/" + date.getDate() + "/" + date.getFullYear();
    }
}

回答2:

For a nullable date time, DateTime?, you will want to use a different rendering function:

        $('#userData').DataTable({
        columns: [
            { "data": "userId"},
            {"data": "userCreated",
             "type": "date ",
             "render":function (value) {
                 if (value === null) return "";

                  var pattern = /Date\(([^)]+)\)/;
                  var results = pattern.exec(value);
                  var dt = new Date(parseFloat(results[1]));

                  return (dt.getMonth() + 1) + "/" + dt.getDate() + "/" + dt.getFullYear();}
            }
        ]};

i have created demo using moment js and use of render function to convert json data into required format.

jsfiddle demo

also find code below:

testdata = [{
    "id": "58",
        "country_code": "UK",
        "title": "Legal Director",
        "pubdate": "1422454697373",
        "url": "http://..."
}, {
    "id": "59",
        "country_code": "UK",
        "title": "Solutions Architect,",
        "pubdate": "1422454697373",
        "url": "http://..."
}];

$('#test').dataTable({
    "aaData": testdata,
        "aoColumns": [{
        "mDataProp": "id"
    }, {
        "mDataProp": "country_code"
    }, {
        "mDataProp": "title"
    }, {
        "mDataProp": "pubdate"
    }, {
        "mDataProp": "url"
    }],
        "columnDefs": [{
        "targets": 3,
            "data": "pubdate",
            "render": function (data, type, full, meta) {
                console.log('hi...');
            console.log(data);
                console.log(type);
                console.log(full);
                console.log(meta);
            return moment.utc(data, "x").toISOString();
        }
    }]
});

I always use moment.js(http://momentjs.com/) when dealing with dates in js.

The date values returned are in unix timestamp so you need to convert them.

Here's a sample fiddle: http://jsfiddle.net/fws8u54g/

var created = 1422010854246;
moment.utc(created, "x").toISOString();

回答5:

{
  "render": function (data) {
              var d = new Date(data);
              return d.toLocaleString();
}

For dot.net and javascript, you can just use like @David Sopko

 {
                "data": "Date", "type": "date ",
                "render": function (value) {
                    if (value === null) return "";
                    var pattern = /Date\(([^)]+)\)/;//date format from server side
                    var results = pattern.exec(value);
                    var dt = new Date(parseFloat(results[1]));

                    return dt.getDate() + "." + (dt.getMonth() + 1) + "." + dt.getFullYear();
                }, "autoWidth": true
            },

For showing the time along with the date add the code below:

"data": 'Date' , 
                        "render": function (data) {
                            var date = new Date(data);
                            var month = date.getMonth() + 1;
                            return (month.length > 1 ? month : "0" + month) + "/" + date.getDate() + "/" + date.getFullYear() + "&nbsp;&nbsp;" +(date.getHours() < 10 ? ("0"+date.getHours()) : date.getHours())+ ":"+(date.getMinutes() < 10 ? ("0"+date.getMinutes()) : date.getMinutes()) ; 
                            //return date;
                        }
