在前端的项目开发中 下载文件压缩包是很重要的一个环节那么怎么下载多个文件并压缩成ZIP下载呢
二、使用步骤
1、引用库
script typetext/javascript src~/Scripts/comm/jszip.min.js /scriptscript typetext/javascript src~/Scripts/comm/FileSaver.min.js /script
库下载地址https://download.csdn.net/download/u012949335/88088658
2、简单使用方法 var zip new JSZip();
var zipName test;
var fileFolder zip.folder(zipName);
fileFolder.file(fileList[k].name, fileList[k].content, {binary: true //二进制});
zip.generateAsync({type: blob}).then(function(content){saveAs(content, zipName.zip);}); 3、封装高级用法
/**
*批量下载文件
*param { Array } array 待下载数据
*param { String } data 参数需包含属性gndm
*param { String } dg datagrid的id
*param { String } url 请求下载文件url
*param { String } filefolder 压缩文件夹
*param { String } zipname 下载文件名称
*param { String } field 失败显示字段名称
*param { Boolean } tooltips 是否显示提示信息
*example $.ajaxRecursionZipDownFile({ array: infolist, data: { gndm: gndm }, datagrid: XX, url: XXXX, filefolder: XX附件, zipname: XX附件.zip, field: xh });
*/
jQuery.ajaxRecursionZipDownFile function (option) {if (typeof option undefined) throw new Error(Please pass parameters);if (typeof option.url undefined) throw new Error(Please pass parameters url);if (typeof option.array undefined) throw new Error(Please pass parameters array);if (typeof option.field undefined || option.field null) option.field xh;option.data option.data || {};if (option.data.hasOwnProperty(gndm) false) throw new Error(Please pass parameters data-gndm);option.zipname option.zipname || 附件;option.filefolder option.filefolder || 附件;option.tooltips option.tooltips || false;var zip new JSZip();var fileFolder zip.folder(option.filefolder);var fileName ;var _currentIndex 0;var _successIndex 0;var _faileXhInfo ;var _currentTotal option.array.length;pageLoadDown();function _recursionZipDownFiles() {if (_currentIndex _currentTotal) {zip.generateAsync({ type: blob }).then(function (content) {saveAs(content, option.zipname);dispageload();var msg 压缩成功 _successIndex.toString() 个。失败数据 (_faileXhInfo || 无。);if (option.datagrid) $(# option.datagrid).datagrid(clearChecked);if (option.tooltips true) {$.messager.alert(提示, msg, infoxx);if (!this._endmessagertimeout) {window.clearTimeout(this._endmessagertimeout);}this._endmessagertimeout setTimeout($(\.messager-body\).window(close);, 1000);}});return false;}var jsonObject JSON.stringify(option.array[_currentIndex]);var _objdata option.data;_objdata.json jsonObject;axios({method: post,url: option.url,data: _objdata,responseType: blob}).then(function (res) {var data res.data;var reqHeader res.headers;if (reqHeader[content-disposition]) fileName decodeURI(reqHeader[content-disposition]).split(; )[1].split(filename)[1];if (data.size 0) {fileFolder.file(fileName, data, { binary: true });_successIndex;} else {_faileXhInfo option.array[_currentIndex][option.field] ;;}_currentIndex;_changeProcess(Math.round((_currentIndex / _currentTotal) * 100));_recursionZipDownFiles(option.array, option.data.gndm);}, function (err) {_currentIndex;_faileXhInfo option.array[_currentIndex][option.field] ;;_changeProcess(Math.round((_currentIndex / _currentTotal) * 100));});}_recursionZipDownFiles();
}
4、调用示例 function getFilesZipDownInfo(gndm) {var rows $(#dg).datagrid(getChecked);if (rows.length 0) {$.messager.alert(提示, 请选择要下载的数据, error);return;}var infolist [];$.each(rows, function (index, row) {var info new Object();info.idxx row.idxx;info.fjmcxx row.fjmcxx;infolist.push(info);});$.ajaxRecursionZipDownFile({array: infolist,data: { gndm: gndm },datagrid: dg,url: downfile,filefolder: 实验报告附件,zipname: 实验报告附件.zip,field: idxx,tooltips: true});}5、效果展示
