I am trying to implement an export to CSV functionality inside my asp.net mvc. So i added the following link inside a partial view:-
<a href="#" class="export">Export Table data into Excel</a>
and inside the _layout view i call the following script:-
$(document).ready(function () {
function exportTableToCSV($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('"', '""'); // 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
});
});
i am using the table2CSV plugin as follow:-
jQuery.fn.table2CSV = function (options) {
var options = jQuery.extend({
separator: ',',
header: [],
delivery: 'popup' // popup, value
},
options);
var csvData = [];
var headerArr = [];
var el = this;
//header
var numCols = options.header.length;
var tmpRow = []; // construct header avalible array
if (numCols > 0) {
for (var i = 0; i < numCols; i++) {
tmpRow[tmpRow.length] = formatData(options.header[i]);
}
} else {
$(el).filter(':visible').find('th').each(function () {
if ($(this).css('display') != 'none') tmpRow[tmpRow.length] = formatData($(this).html());
});
}
row2CSV(tmpRow);
// actual data
$(el).find('tr').each(function () {
var tmpRow = [];
$(this).filter(':visible').find('td').each(function () {
if ($(this).css('display') != 'none') tmpRow[tmpRow.length] = formatData($(this).html());
});
row2CSV(tmpRow);
});
if (options.delivery == 'popup') {
var mydata = csvData.join('\n');
return popup(mydata);
} else {
var mydata = csvData.join('\n');
return mydata;
}
function row2CSV(tmpRow) {
var tmp = tmpRow.join('') // to remove any blank rows
// alert(tmp);
if (tmpRow.length > 0 && tmp != '') {
var mystr = tmpRow.join(options.separator);
csvData[csvData.length] = mystr;
}
}
function formatData(input) {
// replace " with “
var regexp = new RegExp(/["]/g);
var output = input.replace(regexp, "“");
//HTML
var regexp = new RegExp(/\<[^\<]+\>/g);
var output = output.replace(regexp, "");
if (output == "") return '';
return '"' + output + '"';
}
function popup(data) {
var generator = window.open('', 'csv', 'height=400,width=600');
generator.document.write('<html><head><title>CSV</title>');
generator.document.write('</head><body >');
generator.document.write('<textArea cols=70 rows=15 wrap="off" >');
generator.document.write(data);
generator.document.write('</textArea>');
generator.document.write('</body></html>');
generator.document.close();
return true;
}
};
But currently when i user clicks on the link, nothing will happen. but if i move the link to be inside the main view instead of inside the partial view the script will fire. but on the main view no data will be displyed , so i want the "Export Table data into Excel" to be rendered whenever the partial view is rendered,, so can anyone adivce on this please?
