我想填充一个表格并将其导出为 csv。以下是我的代码
<html>
<head>
<title></title>
</head>
<body>
<div class="container">
<h1>Build Table</h1>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<div>
<table id="blacklistgrid">
<tr id="Row1">
<td>Week Number</td>
<td>Oranges Sold</td>
<td>Apples Sold</td>
</tr>
<tr class="Row2">
<td>
<input type="text"/>
</td>
<td>
<input type="text"/>
</td>
<td>
<input type="text"/>
</td>
</tr>
</table>
<button type="button" id="btnAdd">Add Row!</button>
<button><a href="#" class="export">Export Table data into Excel</a></button>
</div>
<script>
jQuery(document).ready(function () {
jQuery('#btnAdd').click(function () {
jQuery( ".Row2" ).clone().appendTo( "#blacklistgrid" );
});
});
$(document).ready(function() {
function exportTableToCSV($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) + '"';
// Deliberate 'false', see comment below
if (false && window.navigator.msSaveBlob) {
var blob = new Blob([decodeURIComponent(csv)], {
type: 'text/csv;charset=utf8'
});
// Crashes in IE 10, IE 11 and Microsoft Edge
// See MS Edge Issue #10396033
// Hence, the deliberate 'false'
// This is here just for completeness
// Remove the 'false' at your own risk
window.navigator.msSaveBlob(blob, filename);
} else if (window.Blob && window.URL) {
// HTML5 Blob
var blob = new Blob([csv], {
type: 'text/csv;charset=utf-8'
});
var csvUrl = URL.createObjectURL(blob);
$(this)
.attr({
'download': filename,
'href': csvUrl
});
} else {
// Data URI
var csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);
$(this)
.attr({
'download': filename,
'href': csvData,
'target': '_blank'
});
}
}
// This must be a hyperlink
$(".export").on('click', function(event) {
// CSV
var args = [$('#blacklistgrid'), 'export.csv'];
exportTableToCSV.apply(this, args);
// If CSV, don't do event.preventDefault() or return false
// We actually need this to be a typical hyperlink
});
});
</script>
</body>
</html>
我可以动态填充表格并添加行。但是，我似乎无法将填充的数据导出到 csv 文件。我做错了什么？
最佳答案
由于您使用的是输入元素，text()方法不起作用 - 本质上你的 <td> 之间没有任何东西元素。相反，您想使用 val()从所述输入元素获取文本的方法。这是一个简单的示例:https://jsfiddle.net/dzy5ktv6/
请注意，我将选择器更改为选择 input元素而不是 td .
关于javascript - 无法将表导出为 csv，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42584150/
