js前端解析excel文件

使用纯Javascript解析excel文件。

使用的是开源的解析excel的js库：sheetjs。github地址：https://github.com/SheetJS/js-xlsx

首先引用JS库

<script src="od.js"></script>

<script src="jszip.js"></script>

<script src="xlsx.js"></script>

放置页面组件

<body>

    <div id="drop">Drop an XLSX / XLSM / XLSB / ODS / XLS / XML file here to see sheet data</div>

    <p><input type="file" name="xlfile" id="xlf" /> ... or click here to select a file</p>

</body>

页面效果如下：

给dom元素添加监听

function addLis() {

    var xlf = document.getElementById('xlf');

    var drop = document.getElementById('drop');

    drop.addEventListener("dragenter", handleDragover, false);

    drop.addEventListener("dragover", handleDragover, false);

    drop.addEventListener("drop", onDropDown, false);

    if(xlf.addEventListener) xlf.addEventListener('change', handleFile, false);

}

addLis();

function handleDragover(e) {

    e.stopPropagation();

    e.preventDefault();

    e.dataTransfer.dropEffect = 'copy';

}

function onDropDown(e) {

    e.stopPropagation();

    e.preventDefault();

    var files = e.dataTransfer.files;

    var f = files[0];

    readFile(f);

}

function handleFile(e) {

    var files = e.target.files;

    var f = files[0];

    readFile(f);

}

读取文档并输出到控制台：

function readFile(file) {

    var name = file.name;

    var reader = new FileReader();

    reader.onload = function (e) {

        var data = e.target.result;

        var wb = XLSX.read(data, { type: "binary" });

        console.log(wb);

    };

    reader.readAsBinaryString(file);

}

输出示例：
