我正在努力将子行添加到数据表中，但对于在不同表和页面上完美运行的一行代码，出现“类型错误：未定义不是函数”。有任何想法吗？
HTML:
<div class="table-responsive">
<h2 class="sub-header">Account Users <a href="?q=support"><span class="glyphicon glyphicon-question-sign"></span></a></h2>
<table id="users_table" class="table table-striped embedded_table">
<thead>
<tr class="text-center">
<th></th>
<th>User Name</th>
<th>Full Name</th>
<th>User Type</th>
<th>Assigned Device</th>
<th>Date Added</th>
<th>Action</th>
</tr>
</thead>
</table>
</div>
JavaScript/jQuery：
<script>
function format ( d ) {
var html = '<table id="child_table" class="text-right" cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">'+
'<tr>'+
'<td>Email Address:</td>'+
'<td>'+ d.email_address +'</td>'+
'<td>Time Zone:</td>'+
'<td>'+ d.timezone +'</td>'+
'</tr>'+
'<tr>'+
'<td>Create Date:</td>'+
'<td>'+ d.create_date +'</td>'+
'<td>Last Login:</td>'+
'<td>'+ d.last_login +'</td>'+
'</tr>'+
'</table>';
return html;
}
$(document).ready(function() {
username = "<?php echo($_SESSION["username"]); ?>";
userType = "<?php echo($_SESSION["user_type"]); ?>";
var table = $('#users_table').dataTable({
order: [1, 'asc'],
"ajax": {
"url": "/s/user_data.php",
"dataSrc" : ""
},
"language": {
"search": "Search: "
},
"columns": [
{"data": null, "class": "details-control", "orderable": false, "defaultContent": "", "width": "2%"},
{"data": "username", "name": "username", "width": "20%"},
{"data": "fullName", "name": "fullName", "width": "20%"},
{"data": "type", "name": "type", "width": "15%"},
{"data": "cal_color", "name": "cal_color", "width": "15%"},
{"data": "create_date", "type": "date", "name": "create_date", "visible": false},
{"data": "time_zone", "name": "time_zone", "visible": false},
{"data": "last_login", "type": "date", "name": "last_login", "visible": false},
{"data": "email_address", "name": "email_address", "visible": false},
{"data": "uid", "name": "uid", "visible": false}
]
});
// Add event listener for opening and closing details
$('#users_table').find('tbody').on('click', 'td.details-control', function () {
var tr = $(this).closest('tr');
var td = $(this).closest('td');
var row = table.row(tr);
console.log(tr);
console.log(td);
console.log(row);
if(row.child.isShown())
{
// This row is already open - close it
row.child.hide();
tr.removeClass('shown');
td.removeClass('shown');
}
else
{
// Open this row
row.child(format(row.data())).show();
tr.addClass('shown');
td.addClass('shown');
}
});
});
生成错误的代码行如下。它位于脚本底部三分之一的注释“添加用于打开和关闭详细信息的事件侦听器”下方。
var row = table.row(tr);
就像我说的，我在另一个表上使用相同的侦听器，并且这条线在那里不是问题。我多次检查了标点符号，没有发现缺少任何逗号、分号或引号。您可以看到我有 3 行写入控制台日志。如果我注释掉有问题的行，我会得到以下结果：
[tr.even, prevObject: n.fn.init[1], context: td.details-control, jquery: "1.11.0", constructor: function, selector: ""…]
[td.details-control, prevObject: n.fn.init[1], context: td.details-control, jquery: "1.11.0", constructor: function, selector: ""…]
我不是一个强大的 javascript 或 jQuery 开发人员。欢迎所有意见和建议。
Thanks.
