前言:
今天小伙伴们对“jquery表格筛选xls”大体比较关心,朋友们都想要剖析一些“jquery表格筛选xls”的相关知识。那么小编在网络上网罗了一些有关“jquery表格筛选xls””的相关文章,希望咱们能喜欢,各位老铁们一起来了解一下吧!纯jquery 前端导入 Excel数据 减少服务端压力
前提是要导入jq库在这里就不再累述
重要的是导入xlsx.core.min.js
我根据xlsx.core.min.js编写自己的工具类
这里是导入数据解析的方法
function parseXlsx( workbook, sheetName, jsonObjects, callback ) {
// 遍历每张表读取
if (workbook.Sheets.hasOwnProperty(sheetName)) {
jsonObjects= XLSX.utils.sheet_to_json(workbook.Sheets[sheetName]);
}else
jsonObjects = [];
//处理每条数据
callback(JSON.stringify(jsonObjects), 0 );
}

将excel的file读取成json的格式(此处只能用于非IE浏览器)
function readXlsxFileFromLocal( file, sheetName, jsonObjects, callback ) {
var reader = new FileReader();
reader.onload = function(e) {
var data = e.target.result;
var workbook = XLSX.read(data, {type: 'binary'});
parseXlsx(workbook, sheetName, jsonObjects, callback);
};
reader.readAsBinaryString(file);
}

将excel的sheet读取成sheet1,sheet2,sheet3的字符串(此处只能用于非IE浏览器)
function readXlsxFilesheetNameSFromLocal( file, callback ) {
var reader = new FileReader();
reader.onload = function(e) {
var data = e.target.result;
var workbook = XLSX.read(data, {type: 'binary'});
if(callback)callback( workbook.SheetNames );
};
reader.readAsBinaryString(file);
}

这里是IE浏览器环境下调取方法同上不再累述
function readXlsxFilesheetNameSFromLocalforIE( file, callback ) {
var binary = "";
var pt = this;
var reader = new FileReader();
reader.onload = function (e) {
var bytes = new Uint8Array(reader.result);
var length = bytes.byteLength;
for (var i = 0; i < length; i++) {
binary += String.fromCharCode(bytes[i]);
}
pt.content = binary;
$(pt).trigger('onload');
var workbook = XLSX.read(binary, {type: 'binary'});
if(callback)callback( workbook.SheetNames );
}
reader.readAsArrayBuffer(file);
}
function readXlsxFileFromLocalforIE( file,sheetName,jsonObjects,callback ) {
var binary = "";
var pt = this;
var reader = new FileReader();
reader.onload = function (e) {
var bytes = new Uint8Array(reader.result);
var length = bytes.byteLength;
for (var i = 0; i < length; i++) {
binary += String.fromCharCode(bytes[i]);
}
pt.content = binary;
$(pt).trigger('onload');
var workbook = XLSX.read(binary, {type: 'binary'});
parseXlsx(workbook, sheetName, jsonObjects, callback);
}
reader.readAsArrayBuffer(file);
}

使用时判断是否是IE浏览器
if (!FileReader.prototype.readAsBinaryString) {
console.log("IE");
}else{
console.log("Other");
}
