i am creating ahref tag dynamically using javascript to download csv file generated using javascript code. The following code is working fine in chrome but doesn't work in safari or firefox...

var blob = new Blob([str], {'type':'application\/octet-stream'});
a.href = window.URL.createObjectURL(blob);
a.download = 'export.csv';
a.click();

非常感谢您的帮助.

推荐答案

要使其在Firefox中运行，只需将新元素插入DOM(apendChild等).

To make it work in Firefox, just insert the new element into the DOM (apendChild, etc).

我认为这不适用于Safari:

I don't think this will work in Safari:

不支持
• <a download="">(正确)，AFIAK.例如. a.download =不会做您想要的.您仍然可以使用setAttribute，但是Safari仍然会忽略它.
• 我认为Safari确实不支持下载blob:-URI.

• <a download=""> isn't (properly) supported yet, AFAIK. E.g. a.download = will not do what you want. You could still use setAttribute but Safari will still ignore it.
• I don't think Safari does support downloading of blob:-URIs, anyway.
