我想解析一個.csv文件,該文件將位於使用JavaScript中Papa Parse的已知本地目錄中。如果我有一個機制來要求用戶瀏覽文件,它就像一個魅力。但我無法弄清楚如何讓它在給定的位置自動訪問文件。我覺得我缺少一些簡單的東西,但我不確定是什麼。到目前爲止我的代碼:無法使用Papa Parse對CSV解析進行硬編碼的文件目錄

var data;
// var file = evt.target.files[0];
var file = "\\files\\telemetryData.csv";
Papa.parse(file, {
//makes sure the first line is interpreted as a header, not data
header: true,
//allows stuff to be typed as their respective primitive types instead of only strings. turned off in this case
dynamicTyping: false,
//allows you to define the delimiter if not a default comma
delimiter: ",",
//allows you to define a comment line, which would be skipped by the parser
comments: "//",
//turns on fastmode, quicker but assumes no quoted fields is present
fastmode: true,
download: true,
step: function(results){
console.log(results.data);
}
});

你不能這樣做,理由很充分。如果任何網站上的腳本可以隨意訪問任何訪問者的計算機上的任何文件,那將是非常糟糕的。 –
我明白了。會有解決方法嗎? – YazanLpizra
是的,用戶必須從一個''元素中選擇它,否則你必須通過傳遞一個URL來下載它。 – Matt
