jquery.wordexport.js和FileSaver使用方法
1.引用文件，这里的代码默认打开word为页面视图。一开始打开为Web视图，找了好久的问题才知道原来有视图的说法
<script type="text/javascript" src="js/jquery.js"></script>
<script src="js/FileSaver.js"></script>
<script src='js/wordexport/jquery.wordexport.js'></script>
jquery.wordexport.js源码，直接复制就能使用，这个代码可以导出图片

(function($) {
$.fn.wordExport = function(fileName,style) {
fileName = typeof fileName !== 'undefined' ? fileName : "jQuery-Word-Export";

2.html代码
<div id="exportinfo" style="display: none;">
<table width="100%" border="0" cellspacing="0" cellpadding="0" style="border: #333 solid 1px;">
//里面放表格内容
</table>
</div>
<div onclick='tableToWord()'>导出</div>
3.js代码，在这里修改导出word样式，style中的样式不生效，我这里的样式导出为word中的表格样式，可以直接使用
function tableToWord(){
//将文件名赋值为当天日期
var date = new Date();
var year = date.getFullYear();
var month = date.getMonth() + 1;
var day = date.getDate();
month = (month > 9) ? month : ("0" + month);
day = (day < 10) ? ("0" + day) : day;
var today = year + month + day;
let styles = "table th{border-right: 1px #676767 solid;border-bottom: 1px #676767 solid;font-size: 15px;}table td{border-right: 1px #676767 solid;border-bottom: 1px #676767 solid;font-size: 15px;text-align:center}"
//两个参数，导出文件名以及样式
$("#exportinfo").wordExport(today+"文档",styles);
}
导出文件合并单元格
由于表格数据都是后端给的，所以合并单元格本来是在js中使用hide也就是display:none进行的，用这个导出发现，无法识别display:none，导出时会多很多个空白格，所以要将hide，改为remove，下面贴出合并单元格代码
//给想合并的列的<td>标签里定义class
function table_rowspan(classname) {
var first_td = "";
var current_td = "";
var row_num = 0;
$("."+classname).each(function (i) {
if (i == 0) {
first_td = $(this);
row_num = 1;
} else {
var j = i -1;
current_td = $(this);
//将判断的值放在td的value中
if ((first_td.attr("value") == current_td.attr("value"))){
row_num++;
current_td.remove();
first_td.attr("rowspan", row_num);
}
else {
first_td = $(this);
row_num = 1;
}
}
})
}
导出文件表头问题
导出时发现word文档每页都有一个表头，用户不需要这个样式，将table中的thead和tbody标签去掉就解决了
导出文件页边距修改
1.将目标格式的word文件另存为html文件，找到其中style，如图所示
2.将代码然后复制到项目代码里去，我这里的代码页边距为“适中”
function tableToExcel(){
var date = new Date();
var year = date.getFullYear();
var month = date.getMonth() + 1;
var day = date.getDate();
month = (month > 9) ? month : ("0" + month);
day = (day < 10) ? ("0" + day) : day;
var today = year + month + day;
let styles = "@page{mso-page-border-surround-header:no;mso-page-border-surround-footer:no;}@page Section0{margin-top:72.0000pt;margin-bottom:72.0000pt;margin-left:54.0000pt;margin-right:54.0000pt;size:595.3000pt 841.9500pt;mso-header-margin:42.5500pt;mso-footer-margin:49.6000pt;}div.Section0{page:Section0;}table th{border-right: 1px #333 solid;border-bottom: 1px #333 solid;font-size: 14px;}table td{border-right: 1px #333 solid;border-bottom: 1px #333 solid;font-size: 14px;text-align:center}"
$("#exportinfo").wordExport(today+"检测结果汇总",styles);
}
3.修改jquery.wordexport.js文件，如图所示红色区域
body: "<body><div class='Section0'>_body_</div></body>"
