在javascript中读取本地csv文件？

下面是如何使用

readAsBinaryString()

<p>Select local CSV File:</p><input id="csv" type="file"><output id="out">    file contents will appear here</output>

基本上，只需要侦听change事件

<input type="file">

var fileInput = document.getElementById("csv"),    readFile = function () {        var reader = new FileReader();        reader.onload = function () { document.getElementById('out').innerHTML = reader.result;        };        // start reading the file. When it is done, calls the onload event defined above.        reader.readAsBinaryString(fileInput.files[0]);    };fileInput.addEventListener('change', readFile);
