使用指定的charset下载BLOB内容 [英] Download BLOB content using specified charset

问题描述

有可能真的改变Blob charset吗？我正在尝试几个小时，但它不起作用。 查看此 。

Is possible to change the Blob charset really? I'm trying it for hours but it doesn't workds. See this.

jQuery("#download").click(function() {
    var csv_content = jQuery("#csv").val(),
        download = document.createElement("a"),
        blob = new Blob([csv_content], { type: "text/csv;charset=ISO-8859-1" });

    download.href = window.URL.createObjectURL(blob);
    download.download = "test.csv";

    var event = document.createEvent("MouseEvents");
    event.initMouseEvent(
        "click", true, false, window, 0, 0, 0, 0, 0
        , false, false, false, false, 0, null
    );
    download.dispatchEvent(event);    
});

我需要导出一个CSV才能在Excel上打开，但它总是以UTF-8和Excel保存无法处理它。

I need export a CSV to open on Excel, but it always is save with UTF-8 and Excel can't handle it.

推荐答案

我发现之前的解决方案。

事实上，charset的变化尚未得到解决。但是，我发送了UTF-8标头用于下载过程，Excel能够正确理解文件格式。 感谢ErikTöyrä的回复。

The change of charset has not been resolved, in fact. However, I sent the UTF-8 header for the download process and Excel was able to understand the file format correctly. Thanks to this response of Erik Töyrä.

blob = new Blob(["\ufeff", csv_content]);
