（纯前台）读取、解析并展示xls/xlsx

写一个当时让我弄了好几天的东西吧..

纯前台读取、解析Excel 表格，并展示在页面上的一个插件。（需要自行修改代码）。

地址是：

http://www.uedsc.com/js-xlsx.html

我通过修改了一些代码后，展示如图：

话不多说..我把他的代码拿上来

});
});
})
$("#out").on('dblclick','.duoCXTR',function(){
$(this).children("td").eq(7).children('a').click()
})
}

这里主要修改的代码是：

var excelarr = output[1].split(",");
var j = Math.ceil(excelarr.length/6);
if(out.innerText === undefined) out.textContent = output;
else{
var k=1;
$("#duocxresult").css("display","block");
$(".excelbody").empty();
for(var i = 1;i<j-1;i++){
if(excelarr[6*i].substring(1,excelarr[6*i].length)!==""||excelarr[6*i+1]!==""||excelarr[6*i+2]!==""||excelarr[6*i+3]!==""||excelarr[6*i+4]!==""||excelarr[6*i+5]!=="")
{$(".excelbody").append("<tr class='duoCXTR' duospid='' duoresultxml=''><td>"+k+"</td><td class='duoBCXRXM'>"+excelarr[6*i].substring(1,excelarr[6*i].length)+"</td><td class='duoZJZL'>"+excelarr[6*i+1]+"</td><td class='duoZJHM'>"+excelarr[6*i+2]+"</td><td class='duoQZHZMH'>"+excelarr[6*i+3]+"</td><td class='duoZL'>"+excelarr[6*i+4]+"</td><td class='duoFCID'>"+excelarr[6*i+5]+"</td><td><a class='duoRESULTCOUNT'></a></td></tr>")
k++}
}

我是通过console.log(output)，发现了规律，从而对output进行修改，将其改成我需要的格式，然后动态添加进table中。

大部分内容我是一点都没动，（因为我看不懂）。不过还好我会用脑子...感觉现在写代码全靠脑子啊，因为基础不够。

我忘记了output的形式了...后面会补上
