Export data from jqxgrid - jqxgrid

Question

I want to export all data in my jqxgrid into json and send it to another page via AJAX.
My problem is when I click export button, the data in the grid and data before export was not the same. It change float number to Interger. Here is my code:
Javascript:
$('#export_bt').on('click', function(){
var row = $("#jqxgrid").jqxGrid('exportdata', 'json');
$('#debug').html(row);
console.log(row);
});
var tableDatas = [
{"timestamp":"06:00:00","A":99.49,"B":337.77,"C":155.98},
{"timestamp":"07:00:00","A":455.67,"B":474.1,"C":751.68},
{"timestamp":"08:00:00","A":1071.02,"B":598.14,"C":890.47}
];
var tableDatafields = [
{"name":"timestamp","type":"string"},
{"name":"A","type":"number"},
{"name":"B","type":"number"},
{"name":"C","type":"number"}
];
var tableColumns = [
{"text":"Times","datafield":"timestamp","editable":"false","align":"center","cellsalign":"center","width":150},
{"text":"A","datafield":"A","editable":"false","align":"center"},
{"text":"B","datafield":"B","editable":"false","align":"center"},
{"text":"C","datafield":"C","editable":"false","align":"center"}
];
function setTableData(table_data,table_column,table_datafields)
{
sourceTable.localdata = table_data;
sourceTable.datafields = table_datafields;
dataAdapterTable = new $.jqx.dataAdapter(sourceTable);
$("#jqxgrid").jqxGrid({columns:table_column});
$("#jqxgrid").jqxGrid('updatebounddata');
$('#jqxgrid').jqxGrid('sortby', 'timestamp', 'asc');
$("#jqxgrid").jqxGrid('autoresizecolumns');
for(var i=0;i<table_column.length;i++){
$('#jqxgrid').jqxGrid('setcolumnproperty',table_column[i].datafield,'cellsrenderer',cellsrenderer);
}
}
var cellsrenderer = function (row, columnfield, value, defaulthtml, columnproperties) {
if (value||value===0) {
return value;
}
else {
return '-';
}
};
var sourceTable ={ localdata: '', datatype: 'array'};
var dataAdapterTable = new $.jqx.dataAdapter(sourceTable);
dataAdapterTable.dataBind();
$("#jqxgrid").jqxGrid({
width: '500',
autoheight:true,
source: dataAdapterTable,
sortable: true,
columnsresize: false,
selectionmode: 'none',
columns: [{ text: '', datafield: 'timestamp', width:'100%' , editable: false, align:'center'}]
});
setTableData(tableDatas,tableColumns,tableDatafields);
Html:
<div id="jqxgrid"></div>
<button id="export_bt">Export</button>
<div id="debug"></div>

Answer 1

You can add the data type in your source object as below.
datafields: [{ "name": "timestamp", "type": "number" }]
And also I suggest you to apply cellsformat in your column definition.
{ text: 'timestamp', datafield: 'timestamp', cellsalign: 'right', cellsformat: 'd' }
The possible formats can be seen here.
Hope that helps

Answer 2

You can export data in very fast way just like it is id jqxGrid with
var rows = $("#jqxGrid").jqxGrid("getrows");
It will be json array.
