我有4列的表，每列包含文本字段和按钮，每行末尾包含编辑和删除按钮。 我想将表导出为excel格式，但是当我在列标题处执行文本字段和按钮时，编辑和删除按钮也会导出到我不想要的excel文件中。 请问任何人都可以告诉我在javascript中出错的地方。
这是我从网络（http://jsfiddle.net/insin/cmewv/）
获得的jquery代码<script type="text/javascript">
var tableToExcel = (function() {
var uri = 'data:application/vnd.ms-excel;base64,'
, template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
, base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
, format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
return function(table, name) {
if (!table.nodeType) table = document.getElementById(table)
var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}
window.location.href = uri + base64(format(template, ctx))
}
})()
</script>
我的HTML代码如下
<TABLE id="table_id" class="display" align="Center" border="1px" width="80%">
<thead>
<tr>
<th> <b>User_ID </th></b>
<form action="SearchId" method="post">
<input type="hidden" name="hiddenname" value="hidden_uid" >
<input type="text" name="uid" id="uid">
<input type="submit" value="Search">

<td><%=s %></td>
<td><%=itr.next() %></td>
<td><%=itr.next() %></td>
<td><%=itr.next() %></td>
<form id="edit" action="EditRecord" method="post" >

</TABLE>
答案 0 :(得分：3)
尝试使用带有按钮的set标签和带有类的编辑文本来识别此dom的ex：Class ='ignore'。 在这个克隆之后，这个yout表和克隆表删除了你所拥有的所有类的dom。 删除此dom后，将克隆的表传递给将导出为excel的函数。
编辑-------
试试这个。
