必要标签

<iframe id="HideFrm" style="display: none"></iframe>  

<div id="div_list">  

 <table id="list4">  

</table>  

</div>  

<button id="export" value="导出">导出</button> 

    那个iframe可要可不要，不要的话导出的时候会弹出一个网页窗口，要的话比较有好一点，反正是display: none的。table是你要转换为jqGrid的,必须要有一个DIV包裹住这个TABLE，因为导出中要取TABLE的列名要用到。然后对button写一个click事件调用getXlsFromTbl这个方法执行导出就好了。

    getXlsFromTbl有四个参数：第一个参数是要转换成JQGRID的table的ID，第二个参数是包裹这个table的DIV的ID，第三个是用来拼接导出文件名的,第四个参数是指示是否JQGRID显示了rownumbers，就是最前面那一串序号123456什么的。如果你的JQGRID参数设置了rownumber:true,那这边参数就填true,反之同理,否则导出的的文件列会对歪一列.
