Javascript的Excel表
我有一个HTML页面上有一些graphics。 我想要做的是写一个加载的JavaScript函数，它将从Excel工作表读取值，将它们存储在variables中，并使用HTML页面上的值。 我的问题是有没有处理Excel表格的任何JavaScript API，从Excel表单元格parsing值？
我在javascript中编写了一个xlsxparsing器。 https://gist.github.com/trevordixon/3375836
/* Relies on jQuery, underscore.js, Async.js (https://github.com/caolan/async), and zip.js (http://gildas-lormeau.github.com/zip.js). Tested only in Chrome on OS X. Call xlsxParser.parse(file) where file is an instance of File. For example (untested): document.ondrop = function(e) { var file = e.dataTransfer.files[0]; excelParser.parse(file).then(function(data) { console.log(data); }, function(err) { console.log('error', err); }); } */ xlsxParser = (function() { function extractFiles(file) { var deferred = $.Deferred(); zip.createReader(new zip.BlobReader(file), function(reader) { reader.getEntries(function(entries) { async.reduce(entries, {}, function(memo, entry, done) { var files = ['xl/worksheets/sheet1.xml', 'xl/sharedStrings.xml']; if (files.indexOf(entry.filename) == -1) return done(null, memo); entry.getData(new zip.TextWriter(), function(data) { memo[entry.filename.split('/').pop()] = data; done(null, memo); }); }, function(err, files) { if (err) deferred.reject(err); else deferred.resolve(files); }); }); }, function(error) { deferred.reject(error); }); return deferred.promise(); } function extractData(files) { var sheet = $(files['sheet1.xml']), strings = $(files['sharedStrings.xml']), data = []; var colToInt = function(col) { var letters = ["", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z"]; var col = $.trim(col).split(''); var n = 0; for (var i = 0; i < col.length; i++) { n *= 26; n += letters.indexOf(col[i]); } return n; }; var Cell = function(cell) { cell = cell.split(/([0-9]+)/); this.row = parseInt(cell[1]); this.column = colToInt(cell[0]); }; var d = sheet.find('dimension').attr('ref').split(':'); d = _.map(d, function(v) { return new Cell(v); }); var cols = d[1].column - d[0].column + 1, rows = d[1].row - d[0].row + 1; _(rows).times(function() { var _row = []; _(cols).times(function() { _row.push(''); }); data.push(_row); }); sheet.find('sheetData row c').each(function(i, c) { var $cell = $(c), cell = new Cell($cell.attr('r')), type = $cell.attr('t'), value = $cell.find('v').text(); if (type == 's') value = strings.find('si t').eq(parseInt(value)).text(); data[cell.row - d[0].row][cell.column - d[0].column] = value; }); return data; } return { parse: function(file) { return extractFiles(file).pipe(function(files) { return extractData(files); }); } } })(); 您可以尝试使用ActiveXObject从Excel中读取数据。 有各种实用的方法。
