我对数据表有一个问题。我也浏览了这个链接，但没有任何结果。我已经包括了将数据直接解析到DOM中的所有先决条件。
脚本
$(document).ready(function() {
$('.viewCentricPage .teamCentric').dataTable({
"bJQueryUI": true,
"sPaginationType": "full_numbers",
"bPaginate": false,
"bFilter": true,
"bSort": true,
"aaSorting": [
[1, "asc"]
],
"aoColumnDefs": [{
"bSortable": false,
"aTargets": [0]
}, {
"bSortable": true,
"aTargets": [1]
}, {
"bSortable": false,
"aTargets": [2]
}],
});
});
In my case, and using ASP.NET GridView, UpdatePanel and with DropDownList (with Chosen plugin where I reset value to zero using a Javascript line), I got this error and tried everything with no hope for days. The problem was that the code of my dropdown in code behind was as follows and when I select a value twice to apply its action to selected grid rows I get that error. I thought for days it's a Javascript issue (again, in my case) and finally the fix was giving zero for the drowpdown value with the update process:
private void ddlTasks_SelectedIndexChanged(object sender, System.EventArgs e)
{
if (ddlTasks.SelectedValue != 0) {
ChangeStatus(ddlTasks.SelectedValue);
ddlTasks.SelectedValue = "0"; //// **This fixed my issue**
}
dvItemsGrid.DataSource = CreateDatasource();
dvItemsGrid.DataBind();
dvItemsGrid.UseAccessibleHeader = true;
dvItemsGrid.HeaderRow.TableSection = TableRowSection.TableHeader;
}
这是我的错:
$('#<%= DropDownList.ClientID%>').val('0').trigger("chosen:updated").chosen();
无法读取未定义的属性'fnSetData'的常见原因是列数不匹配，就像下面的错误代码:
<thead> <!-- thead required -->
<tr> <!-- tr required -->
<th>Rep</th> <!-- td instead of th will also work -->
<th>Titel</th>
<!-- th missing here -->
</tr>
</thead>
<tbody>
<tr>
<td>Rep</td>
<td>Titel</td>
<td>Missing corresponding th</td>
</tr>
</tbody>
下面的代码中，每<td>(列数必须匹配)包含一个<th>:
<thead>
<tr>
<th>Rep</th> <!-- 1st column -->
<th>Titel</th> <!-- 2nd column -->
<th>Added th</th> <!-- 3rd column; th added here -->
</tr>
</thead>
<tbody>
<tr>
<td>Rep</td> <!-- 1st column -->
<td>Titel</td> <!-- 2nd column -->
<td>th now present</td> <!-- 3rd column -->
</tr>
</tbody>
当使用带有colspan但没有第二行的格式良好的标题时，也会出现这种错误。
对于一个有7列的表，下面的不工作，我们看到“不能读取属性'mData' of undefined”在javascript控制台中:
<thead>
<tr>
<th>Rep</th>
<th>Titel</th>
<th colspan="5">Download</th>
</tr>
</thead>
虽然这是有效的:
<thead>
<tr>
<th rowspan="2">Rep</th>
<th rowspan="2">Titel</th>
<th colspan="5">Download</th>
</tr>
<tr>
<th>pdf</th>
<th>nwc</th>
<th>nwctxt</th>
<th>mid</th>
<th>xml</th>
</tr>
</thead>
我遇到了同样的问题，但我是动态生成表。在我的例子中，我的表缺少<thead>和<tbody>标签。
下面是我的代码片段，如果它对某人有帮助的话
//table string
var strDiv = '<table id="tbl" class="striped center responsive-table">';
//add headers
var strTable = ' <thead><tr id="tableHeader"><th>Customer Name</th><th>Customer Designation</th><th>Customer Email</th><th>Customer Organization</th><th>Customer Department</th><th>Customer ContactNo</th><th>Customer Mobile</th><th>Cluster Name</th><th>Product Name</th><th> Installed Version</th><th>Requirements</th><th>Challenges</th><th>Future Expansion</th><th>Comments</th></tr> </thead> <tbody>';
//add data
$.each(data, function (key, GetCustomerFeedbackBE) {
strTable = strTable + '<tr><td>' + GetCustomerFeedbackBE.StrCustName + '</td><td>' + GetCustomerFeedbackBE.StrCustDesignation + '</td><td>' + GetCustomerFeedbackBE.StrCustEmail + '</td><td>' + GetCustomerFeedbackBE.StrCustOrganization + '</td><td>' + GetCustomerFeedbackBE.StrCustDepartment + '</td><td>' + GetCustomerFeedbackBE.StrCustContactNo + '</td><td>' + GetCustomerFeedbackBE.StrCustMobile + '</td><td>' + GetCustomerFeedbackBE.StrClusterName + '</td><td>' + GetCustomerFeedbackBE.StrProductName + '</td><td>' + GetCustomerFeedbackBE.StrInstalledVersion + '</td><td>' + GetCustomerFeedbackBE.StrRequirements + '</td><td>' + GetCustomerFeedbackBE.StrChallenges + '</td><td>' + GetCustomerFeedbackBE.StrFutureExpansion + '</td><td>' + GetCustomerFeedbackBE.StrComments + '</td></tr>';
});
//add end of tbody
strTable = strTable + '</tbody></table>';
//insert table into a div
$('#divCFB_D').html(strDiv);
$('#tbl').html(strTable);
//finally add export buttons
$('#tbl').DataTable({
dom: 'Bfrtip',
buttons: [
'copy', 'csv', 'excel', 'pdf', 'print'
]
});

供参考，数据表需要一个格式良好的表。它必须包含<thead>和<tbody>标签，否则将抛出此错误。还要检查确保包括标题行在内的所有行具有相同的列数。
以下将抛出错误(没有<thead>和<tbody>标签)
<table id="sample-table">
<tr>
<th>title-1</th>
<th>title-2</th>
</tr>
<tr>
<td>data-1</td>
<td>data-2</td>
</tr>
</table>
下面也会抛出一个错误(列数不等)
<table id="sample-table">
<thead>
<tr>
<th>title-1</th>
<th>title-2</th>
</tr>
</thead>
<tbody>
<tr>
<td>data-1</td>
<td>data-2</td>
<td>data-3</td>
</tr>
</tbody>
</table>
