Export to CSV issue - html

Question

Hi I am trying to export dynamic table in the form of csv file. I am facing two issue
Only the first page of the table is getting displayed in the exported file. As it is a dynamically filled table there can be multiple pages. I am allowing 10 items per page.
The file that is getting exported is not in csv format . It is in some default file format.
If somebody could help. Let me know if you need any other details:
Code:
function exportTableToCSV() {
var tab = $('#searchObjectTableTabs').tabs('getSelected');// selecting the table
var tabIndex = $('#searchObjectTableTabs').tabs('getTabIndex', tab);
var data;
var rows;
if (tabIndex == '0') // first index of the tab under which the table will be displayed
{
data = $('#dg').first(); //Only one table
rows = $('#dg').datagrid('getRows');
} else if (tabIndex == '1') // second index
{
data = $('#doc').first(); //Only one table
rows = $('#doc').datagrid('getRows');
}
var csvData = [];
var tmpArr = [];
var tmpStr = '';
data.find("tr").each(function () {
if ($(this).find("th").length) {
$(this).find("th").each(function () {
tmpStr = $(this).text().replace(/"/g, '""');
tmpArr.push('"' + tmpStr + '"');
});
csvData.push(tmpArr);
}
tmpArr = [];
$.each(exportArray, function (index, value) {
csvData.push(exportArray[index].ID + "," + exportArray[index].itemrev + "," + exportArray[index].type + "," + exportArray[index].status + "," + exportArray[index].desc + "," + exportArray[index].owner + "," + exportArray[index].ogrp);
});
csvData.push(tmpArr.join('\n'));
// printObject(tmpArr);
});
var output = csvData.join('\n');
var uri = 'data:application/csv;charset=UTF-8,' + encodeURIComponent(output);
window.open(uri);
}

Please try this one:
$(document).ready(function () {
function exportTableToCSV($table, filename) {
var $rows = $table.find('tr:has(td)'),
// Temporary delimiter characters unlikely to be typed by keyboard
// This is to avoid accidentally splitting the actual contents
tmpColDelim = String.fromCharCode(11), // vertical tab character
tmpRowDelim = String.fromCharCode(0), // null character
// actual delimiter characters for CSV format
colDelim = '","',
rowDelim = '"\r\n"',
// Grab text from table into CSV formatted string
csv = '"' + $rows.map(function (i, row) {
var $row = $(row),
$cols = $row.find('td');
return $cols.map(function (j, col) {
var $col = $(col),
text = $col.text();
return text.replace(/"/g, '""'); // escape double quotes
}).get().join(tmpColDelim);
}).get().join(tmpRowDelim)
.split(tmpRowDelim).join(rowDelim)
.split(tmpColDelim).join(colDelim) + '"',
// Data URI
csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);
$(this)
.attr({
'download': filename,
'href': csvData,
'target': '_blank'
});
}
// This must be a hyperlink
$(".export").on('click', function (event) {
// CSV
exportTableToCSV.apply(this, [$('#dvData>table'), 'export.csv']);
// IF CSV, don't do event.preventDefault() or return false
// We actually need this to be a typical hyperlink
});
});

Answer 2

Thanks for the answer. I have done some editing and now I am able to retrieve the csv file. However I am only getting the values for the first page. For ex: If I have 20 pages in my table grid. the export is happening only for the first page
Is it because of this part of the code: Can we have a different syntax
{
data = $('#dg').first(); //Only one table
rows = $('#dg').datagrid('getRows');
}
Full Code:
function exportTableToCSV(filename) {
var tab = $('#searchObjectTableTabs').tabs('getSelected');// selecting the table
var tabIndex = $('#searchObjectTableTabs').tabs('getTabIndex', tab);
var data;
var rows;
alert('inside');
if (tabIndex == '0') // first index of the tab under which the table will be displayed
{
data = $('#dg').first(); //Only one table
rows = $('#dg').datagrid('getRows');
} else if (tabIndex == '1') // second index
{
data = $('#doc').first(); //Only one table
rows = $('#doc').datagrid('getRows');
}
var csvData = [];
var tmpArr = [];
var tmpStr = '';
data.find("tr").each(function ()
{
if ($(this).find("th").length) {
$(this).find("th").each(function () {
tmpStr = $(this).text().replace(/"/g, '""');
tmpArr.push('"' + tmpStr + '"');
});
csvData.push(tmpArr);
}
tmpArr = [];
$.each(exportArray, function (index, value)
{
csvData.push(exportArray[index].type + "," + exportArray[index].status + "," + exportArray[index].ID + "," + exportArray[index].itemrev + "," + exportArray[index].desc + "," + exportArray[index].owner + "," + exportArray[index].ogrp);
});
csvData.push(tmpArr.join('\n'));
// printObject(tmpArr);
});
alert('before this');
var output = csvData.join('\n');
csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(output);
$(this)
.attr({
'download': filename,
'href': csvData,
'target': '_blank'
});
alert('done');
}
$(".export").on('click', function (event) {
// CSV
exportTableToCSV.apply(this,['export.csv']);
});
