如何从Javascript FileReader获取文件名？ [英] How to get the filename from the Javascript FileReader?

问题描述

我正在使用Javascript FileReader在浏览器中加载图片：

I'm using the Javascript FileReader to load an image in the browser:

e = e.originalEvent;
e.dataTransfer.dropEffect = 'copy';
this.documentFile = e.dataTransfer.files[0];

var reader = new FileReader();
reader.onloadend = function () {
    if (reader.result) {
        console.log(reader);
        $('#theImage').attr('src', reader.result);
    }
};
reader.readAsDataURL(this.documentFile);

这很好用。我现在想获得图像的原始文件名，但我不知道如何在互联网上查找我也找不到任何东西？

This works fine. I now want to get the original filename of the image, but I've got no clue how and looking around the internet I can't find anything either?

有人知道如何通过FileReader获取文件名吗？欢迎提出所有建议！

Does anybody know how I can get the filename through the FileReader? All tips are welcome!

推荐答案

这不是最佳解决方案，但它对我有用。

This is prob not the best solution, BUT it worked for me.

var reader = new FileReader();
reader.fileName = file.name // file came from a input file element. file = el.files[0];
reader.onload = function(readerEvt) {
    console.log(readerEvt.target.fileName);
};

不是最好的答案，而是一个有效的答案。

Not the best answer, but a working one.
