锚标记下载属性无效:Chrome 35.0.1916.114中的错误 [英] Anchor tag download attribute not working :Bug in Chrome 35.0.1916.114
问题描述
我正尝试参考此代码,我们正在点击下载CSV文件一条链接。
I am trying to refer to this code where a we are downloading a CSV file on click of a link.
$(document).ready(function () {
function exportTableToCSV($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
});
});
但不知何故,下载的文件被命名为 download $ c $在Chrome v35.0.1916.114中没有扩展名的情况下,一种解决方法是将数据:application / csv更改为data:text / csv,但这只有助于在下载的文件中正确获取扩展名,即现在以
download.csv
。
But somehow, the downloaded file is named as download
without extension in Chrome v35.0.1916.114 , one workaround was to change data:application/csv to data:text/csv, but that only helped in getting the extension correct in the downloaded file i.e. it now downloads as download.csv
.
下载属性的问题仍然存在。我想将我的文件命名为 export.csv
,但它仍然给我 download.csv
。
The issue with the download attribute still remains. I wanted to name my file as export.csv
, but it still gives me download.csv
.
推荐答案
所以你应该改变它:
So you should change this:
// Data URI
csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);
$(this)
.attr({
'download': filename,
'href': csvData,
'target': '_blank'
});
至此
// Data URI
//csvData = 'data:text/csv;charset=utf-8,' + encodeURIComponent(csv), //old way
blob = new Blob([csv], { type: 'text/csv' }); //new way
var csvUrl = URL.createObjectURL(blob);
$(this)
.attr({
'download': filename,
'href': csvUrl
});
它应该可以工作!
