解决导出EXCEL自动将长的数字的字符串变成E+的科学计数法
|
导出Excel时候出现一个问题:
比如是"订单号"、“手机号”、“身份证”等等,他是一个一长串的数字组成的字符串,导出到EXCEL之后office傻不拉几的自以为是的将这串数字字符串转成"科学计数法",变成如下:
此外，EXCEL还会自动将日期转为英文日期格式，如：
如何解决呢？？ 解决的方法一:导出这个数字字符串的时候,在这串数字前面加一个: 英文的 全角的 单引号 ＇
有了这个单引号' 之后, EXCEL 就认为这个值是字符串了,就不会当做他是数字了,也就不会科学计数法了! 最后再说一遍： 给你的 一长串 数字的 字符串 前面加上: 英文的 全角的 单引号 ＇ 解决的方法二:或者在每个里添加样式: style='mso-number-format:\"\@\";' 7894561230123456789也能实现这个效果 附上完整 table2excel.js 代码(已添加: style='mso-number-format:\"\@\";' , 见112行 ): /* 调用方法: * $('#test_table').table2excel({//'#test_table' table的id * subtotal: 1,//可选参数(可删除此行),默认值:0 * width:200,//导出excel表格的宽度百分比的值(不含%号),可删除此行(默认100%) * filename: 'excel_' + new Date().getTime() + '.xls', //excel文件名称,扩展名:.xlsx 或者.xls * }); */ (function ($, window, document, undefined) { var pluginName = "table2excel", defaults = { exclude: ".noExl", name: "Table2Excel", filename: "table2excel", fileext: ".xls", exclude_img: true, exclude_links: true, exclude_inputs: true, preserveColors: false, subtotal: 0,//"合计"行所在的行号(不包括标题行),0表示没有合计行... width: 100,//表格宽度百分比,默认100% }; //插件配置 function Plugin(element, options) { this.element = element; this.settings = $.extend({}, defaults, options); this._defaults = defaults; this._name = pluginName; this.init(); } Plugin.prototype = { init: function () { var e = this; var w = getWidth(e.settings);//导出EXCEL表格的宽度,默认100% var utf8Heading = ""; e.template = { head: "" + utf8Heading + "", table: { head: " ",//的边框&宽度 tail: " " }, foot: "" }; e.tableRows = []; //读取原始表 var rowNumber = 0;//行号 $(e.element).each(function (i, o) { var tempRows = "";//table的html $(o).find("tr").not(e.settings.exclude).each(function (i, p) { //的样式 var trStyles = "";//整行样式 //开始创建一行表格 if (trStyles) { tempRows += "";//内容居中：align='center' } else { tempRows += "";//内容居中：align='center' } //读取原始的表头行(表头必须是！表头如果是的话则会当做普通数据行处理...) $(p).find("th").not(e.settings.exclude).each(function (i, q) { //的样式: var thStyles = "background-color: cornflowerblue; color:white;"; var rc = { rows: $(this).attr("rowspan"), cols: $(this).attr("colspan"), flag: $(q).find(e.settings.exclude) }; if (rc.flag.length > 0) { tempRows += " "; //空格! } else { tempRows += "" + $(q).html() + "";//内容 } }); //读取原始的数据行 $(p).find("td").not(e.settings.exclude).each(function (i, q) { //的样式 var tdStyles = "background-color:yellow;";//合计行的样式 var rc = { rows: $(this).attr("rowspan"), cols: $(this).attr("colspan"), flag: $(q).find(e.settings.exclude) }; if (rc.flag.length > 0) { tempRows += " "; //空格！ } else { tempRows += "" + $(q).html() + ""; } }); tempRows += "";//生成一行结束 rowNumber++;//行号+1 }); // exclude img tags if (e.settings.exclude_img) { tempRows = exclude_img(tempRows); } // exclude link tags if (e.settings.exclude_links) { tempRows = exclude_links(tempRows); } // exclude input tags if (e.settings.exclude_inputs) { tempRows = exclude_inputs(tempRows); } e.tableRows.push(tempRows); }); e.tableToExcel(e.tableRows, e.settings.name, e.settings.sheetName); }, tableToExcel: function (table, name, sheetName) { var e = this, fullTemplate = "", i, link, a; e.format = function (s, c) { return s.replace(/{(\w+)}/g, function (m, p) { return c[p]; }); }; sheetName = typeof sheetName === "undefined" ?
