我正在开发一个仪表板应用程序,我想实现“下载表为.xls”功能。
在此链接上,您可以看到表格的外观 dashboard
我找到了library,其中还包含解释设置的教程。正如您在下面的代码中所看到的,我已经做了或多或少的事情,就像它解释的那样。但是它不起作用,并且由于某种原因,该表将不会被导出。
正如您所看到的,我在资源中包含了jquery.table2excel.js
以及用于此页面的所有其他资源。我还检查了加载页面后.js
文件是否可用,它看起来也不错。
我也试过这个
$(function () {
document.getElementById('btnExport').addEventListener("click", function () {
document.getElementById('myTable').table2excel({
exclude: ".noExl",
name: "Excel Document Name",
filename: "myFileName"
});
});
});
但它也看起来不太好,当我执行该函数时,我在debugg控制台中收到此消息
TypeError: document.getElementById(...).table2excel is not a function
这就是我index.jsp
目前的样子

我真的不确定是什么原因导致这个问题,或者我在jQuery语法中有错误。也可能是lib在.jsp
页面内没有正确输入,但这是过去对我有用的方式。我想我正在使用正确jQuery
版本,因为jQuery datePicker
工作正常。
如果您能够看到可能出现此问题的原因,请帮我解决。如果你有更好的想法如何将表导出为excel文件,请建议。
提前谢谢。修改1:
我已更改了该功能,它看起来像我在下面发布的代码。如果我在console.log("exporting...");
之前或之后执行$(".table2excel").table2excel({ ... });
“exporing ...”将在控制台中打印出来。显然,将jQuery排除在问题的潜在原因之外。
<script>
$(function () {
$('#btnExport').click(function () {
console.log("exporting...");
$(".table2excel").table2excel({
exclude: ".noExl",
name: "Excel Document Name",
filename: "myFileName"
});
});
});
</script>
编辑2:
由于我无法解决这个问题,我试图尝试一些新的东西。我找到了this解决方案,但它仍然有效,但仍然不是我想要的,所以我希望你可以帮助我改进它。
我的表看起来像这样
这就是我得到的结果
首先,如果没有excel网格,它看起来真的很奇怪,你有没有想法为什么没有它导出文件,我该如何添加呢?
第二,我希望在YTD之后移除列,其中显示了附加信息。是否有可能调整下面的tab_text.replace(...)
以实现此
在html中看起来像这样
</td><td width='20px'>
<a class='infobox' href=''>
<img src='img/info.jpg' alt='info' width='18' height='18'>
<span> Service Engineer: ... <br>
Datasource: ...
</span>
</a>
</tr>
JavaScript函数看起来像这样
function exportExcelReport(tblId) {
var tab_text = "<table border='2px'><tr>";
var table = document.getElementById(tblId);
var style;
for (var j = 0; j < table.rows.length; j++) {
style = table.rows[j].className.split(" ");
if (style.length < 2)
tab_text = tab_text + table.rows[j].innerHTML + "</tr>";
}
tab_text = tab_text + "</table>";
tab_text = tab_text.replace(/<a[^>]*>|<\/a>/g, "");
tab_text = tab_text.replace(/<img[^>]*>/gi, "");
tab_text = tab_text.replace(/<input[^>]*>|<\/input>/gi, "");
return window.open('data:application/vnd.ms-excel,' + encodeURIComponent(tab_text));
}
THX!
答案 0 :(得分:1)
在返回之前添加此内容
tab_text = tab_text.replace(/<a class='infobox'[\s\S]*?<\/a>/gi, "");

确保插件的脚本引用位于jQuery之后,并检查两者是否包含在js代码之前。
