使用指定的字符集下载 BLOB 内容 [英] Download BLOB content using specified charset

问题描述

真的可以更改 Blob 字符集吗?我尝试了几个小时，但它不起作用.看到这个.

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 文件才能在 Excel 上打开，但它总是以 UTF-8 格式保存，Excel 无法处理.

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

我在发帖之前找到了解决方案.

字符集的更改实际上还没有解决.但是，我为下载过程发送了 UTF-8 标头，Excel 能够正确理解文件格式.感谢 Erik Töyrä 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]);
