Javascript-将CSV下载为文件 [英] Javascript - Download CSV as File

问题描述

我正在弄乱一些JavaScript，以下载一些csv文本:

I'm messing with some javascript to download some csv text:

<script>
var data = '"Column One","Column Two","Column Three"';
window.location.href = 'data:text/csv;charset=UTF-8,' + encodeURIComponent(data);
</script>

到目前为止，这是可行的，但是当浏览器提示我保存文件时，没有文件名，也没有扩展名.

So far this is working, but as the browser prompts me to save the file, there is no filename, nor extension.

如何在window.location.href内预先确定文件名及其扩展名?

How can I predetermine the name of the file and it's extension, inside the window.location.href ?

推荐答案

function downloadFile(fileName, urlData) {

    var aLink = document.createElement('a');
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent("click");
    aLink.download = fileName;
    aLink.href = urlData;
    aLink.dispatchEvent(evt);
}

var data = '"Column One","Column Two","Column Three"';
downloadFile('2.csv', 'data:text/csv;charset=UTF-8,' + encodeURIComponent(data));
