解决tableexport导出到excel中有关中文乱码的问题
ableexport中将table中的内容导出到excel,但如果table包含中文的话,导出的就是乱码,需要修改tableexport.js,修改后的tableexport.js如下,使用时,只需引用tableexport.js即可,
页面上加上:
<button class="btn btn-success" onClick ="$('#yourTableId').tableExport({ type: 'excel', escape: 'false' })">导出</button>
tableexport.js修改后的源代码如下:
