我有一张通过Thymeleaf生成的表格。我想使用jQuery刷新表的内容。
<table class="table table-hover" id="main-table">
<thead class="thead-inverse">
<tr>
<th class="col-md-2 text-center">Network Id</th>
<th class="col-md-2 text-center">Rep date</th>
<th class="col-md-2 text-center">Hashrate [KH/s]</th>
</tr>
</thead>
<tbody>
<tr th:each="networkHashrate : ${networkHashrates}" th:onclick="'javascript:openPoolModal(\''+ ${networkHashrate.id} + '\');'">
<td class="text-center" id="hashrateId" th:text="${networkHashrate.id}"> Sample id</td>
<td class="text-center" id="repDate" th:text="${@findAndDisplayDataService.formatDate(networkHashrate.repDate)}">Sample rep-date</td>
<td class="text-center" id="hashrate" th:text="${@findAndDisplayDataService.formatHashrate(networkHashrate.hashrate)}">Sample hashrate</td>
</tr>
</tbody>
</table>
我已经提出了这样的功能来每8秒更新一次表格内容:
$(document).ready(function() {
var table = $('#main-table').DataTable({
ajax: {
url: '/refresh',
dataSrc:''
},
paging: true,
lengthChange: false,
pageLength: 20,
stateSave: true,
info: true,
searching: false,
"aoColumns": [
{ "orderSequence": [ "asc", "desc" ] },
{ "orderSequence": [ "asc", "desc" ] },
{ "orderSequence": [ "desc", "asc" ] }
],
"order": [[ 0, "asc" ]]
});
setInterval(function(){
table.ajax.reload();
}, 8000);
});
这是JSON的回应:
[{
"id":1,
"repDate":{
"offset":{ },
"nano":880042000,
"year":2018,
"monthValue":4,
"dayOfMonth":25,
"hour":12,
"minute":58,
"second":53,
"month":"APRIL",
"dayOfWeek":"WEDNESDAY",
"dayOfYear":115
},
"hashrate":5114926.0
},...more entries
]
打印一张空表,我不断收到错误:
Uncaught TypeError: Cannot read property 'reload' of undefined
还有一个警告弹出窗口说:
Data Tables warning: table id=main-table - Requestem unknown parameter '0' for row 0 column 0. For more information about this error, please see: http://datatables.net/tn/4

我将表声明移到了函数之外。现在我一直在收到警告。

我按照您的说法做了,数据一直在刷新,但仍然存在一些问题。
首先,我的stateSave: true
属性停止工作,所以当重新加载表格时,它总会返回到第一页。
其次,我丢失了原本位于class="text:center"
文件中的所有样式(例如on:click
)和html
属性。
答案 0 :(得分:1)
尝试在$(document).ready:
之前声明表var table;
$(document).ready(function() {
table = $('#main-table').DataTable({"serverSide": true, ...})
setInterval(function(){
table.ajax.reload();
}, 8000);
})
错误与列定义有关,请尝试这种方式来定义列:
"columnDefs": [
{
"targets": 0,
"data": "id",
},
{
"targets": 1,
"data": "repDate",
},
{
"targets": 2,
"data": "repDate",
}
]
