使用Angularjs从前端导出excel文件当通过插件js-xlsx编写excel文件时，得到一个不寻常的内容错误

在打开excel文件时，导出为.xlsm格式的文件，出现以上错误

请在控制器中查看下面的代码，写入excel文件

使用js-xls插件的angular度控制器function。 使用两个名为js-xls和filesaver.js的插件作为blob函数

$scope.exportData = function(){ function Workbook() { if(!(this instanceof Workbook)) return new Workbook(); this.SheetNames = []; this.Sheets = {}; } function sheet_from_array_of_arrays(data, opts) { var ws = {}; var range = {s: {c:10000000, r:10000000}, e: {c:0, r:0 }}; for(var R = 0; R != data.length; ++R) { for(var C = 0; C != data[R].length; ++C) { if(range.sr > R) range.sr = R; if(range.sc > C) range.sc = C; if(range.er < R) range.er = R; if(range.ec < C) range.ec = C; var cell = {v: data[R][C] }; if(cell.v == null) continue; var cell_ref = XLSX.utils.encode_cell({c:C,r:R}); /* TEST: proper cell types and value handling */ if(typeof cell.v === 'number') cell.t = 'n'; else if(typeof cell.v === 'boolean') cell.t = 'b'; else if(cell.v instanceof Date) { cell.t = 'n'; cell.z = XLSX.SSF._table[14]; cell.v = datenum(cell.v); } else cell.t = 's'; //ws['!cols'][C].wch = cell.v.length; ws[cell_ref] = cell; } } /* TEST: proper range */ if(range.sc < 10000000) ws['!ref'] = XLSX.utils.encode_range(range); return ws; } var newArr = [[1,2],[3,4]]; var ws = sheet_from_array_of_arrays(newArr); var wb = new Workbook(); wb.SheetNames.push('DemoSheet'); wb.Sheets['DemoSheet'] = ws; console.log('Object of workbook'); console.log(ws); //var stereotypes = Object.keys($scope.childrenAttrsMap); //console.log(stereotypes); var wopts = { bookType:'xlsm', bookSST:false, type:'binary' }; var wbout = XLSX.write(wb,wopts); console.log(wbout); function s2ab(s) { var buf = new ArrayBuffer(s.length); var view = new Uint8Array(buf); for (var i=0; i!=s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF; return buf; } /* the saveAs call downloads a file on the local machine */ saveAs(new Blob([s2ab(wbout)],{type:"application/octet-stream"}), "Gen_Safe1_data.xlsm"); }
