javascript - 文件未下载 blob 链接

Question

我有下面的代码片段，可以很好地在 IE11、CHROME 中下载“Test.csv”。但在 FIREFOX 39.0 中没有任何反应

任何帮助将不胜感激。

var blob = new Blob([], { type: 'text/csv' });

/* It will work for IE versions
window.navigator.msSaveBlob(blob, 'Test.csv');
*/

var link = document.createElement("a");

//link.setAttribute("onclick","alert('Click Fired')");   

link.href = URL.createObjectURL(blob);
link.download = 'Test.csv';
link.click();

Answer 1

我似乎必须在单击之前将链接添加到 dom

var blob = new Blob([], { type: 'text/csv' });

/* It will work for IE versions
window.navigator.msSaveBlob(blob, 'Test.csv');
*/

var link = document.createElement("a");

//link.setAttribute("onclick","alert('Click Fired')");   

link.href = URL.createObjectURL(blob);
link.download = 'Test.csv';
document.body.appendChild(link);
link.click();
