分页不起作用？？ - jQuery 或 Javascript答案

【问题标题】：Pagination not working?? - jQuery or Javascript分页不起作用？？ - jQuery 或 Javascript
【发布时间】：2019-11-05 05:14:17
【问题描述】：

我只是使用分页创建动态表，但分页不适用于该表..

我正在使用带有 jquery 的引导表。

我希望只显示 5 行，其余行是分页的。

这是我的小提琴

FIDDLE HERE..

动态添加行时如何分页。

这是一个示例代码。

$(document).ready(function() {
  $("#add_Row").on("click", function() {
    var counter = 0;
    var idVal = $('#tab_logic tr:last').find('td:first').html();
    var matches = idVal.match(/\d+/g);
    if (matches != null) {
      counter = Number(matches) + counter + 1;
    }
    // alert(counter);
    var newRow = $("<tr>");
    var cols = "";
    cols += '<td class="cashpay_led" style="display:none;"><input type="number" class="form-control" id="table_ledger' + counter + '" name="ledgerno" placeholder="ledger number"/></td>';
    cols += '<td><input type="number" class="form-control sel_text" id="cashAcctcode' + counter + '" name="acctcode" placeholder="Account code"/></td>';
    cols += '<td><select class="form-control sel_sel status" id="accountName' + counter + '" name="accountName"><option>Choose A/c Name</option></select></td>'
    cols += '<td><textarea class="form-control pname required price" name="narr" placeholder="Enter your text here" id="acc_narrat' + counter + '" maxlength="200"/></textarea></td>';
    cols += '<td><input type="text" class="form-control" id="cashdeb' + counter + '" data-action="sumDebit" name="debit" placeholder="Debit amount"/></td>';
    cols += '<td><input type="number" class="form-control comment" id="crditCash' + counter + '" data-action="sumCredit" name="credit" placeholder="Credit amount" tabindex="-1" readonly/></td>';

    cols += '<td><button type="button" class="adRow ibtnDel" style="width:70%;">x</button></a></td>';

    newRow.append(cols);

    $("table.order-list").append(newRow);
    setValCashVal('accountName'.concat(counter));
    bindScript();
    counter++;
  });

});

// pagination

$(function() {
  $('#tab_logic').DataTable({
    'paging': true,
    'lengthChange': false,
    'searching': true,
    'ordering': true,
    'info': false,
    'autoWidth': false,
    'pageLength': 5
  })
});

我做错了什么？

如何在动态添加行中设置分页。

谢谢

【问题讨论】：

您是否添加了Datatable CDN。因为没有 DATATABLE CDN 。并且第一个选择列表没有值
是的！我正在使用 jQuery 1.10.20 cdn
你好，检查这个答案stackoverflow.com/a/28141195/7943457你需要让数据表知道行已经改变，所以请重新渲染
@Piyush 但它不适合我

标签： javascript jquery

【解决方案1】：

您的代码 sn-p 有一些错误： 1.在表 th 标签小于 td ，您正在附加 2.Jquery定义前调用Datatable

如果你想在动态添加行中设置分页，那么你必须销毁它并重新初始化它。我删除了一些隐藏的属性只是为了检查，你可以隐藏它们添加类 "columnDefs": [{ "class": "hide", "targets": 3 } ] 要么 “columnDefs”：[{“目标”：[2]，“可见”：假}] 希望对你有帮助

【讨论】：

我面临两个错误妈妈，第一个是 “无法读取未定义的属性 'mData'” 第二个是 “无法读取属性 'parentNode' of null”
"无法读取未定义的属性 'mData'" -- 由于标签与附加 td 不同。计算你的 th 和 td 标签使它们等于 count.refere this -- jsfiddle.net/AishwaryaDomde/hvu5kwbo/7/#save 另外“DataTables 不支持表体中的 rowspan / colspan”
妈妈，这是我目前的问题.. 请检查一下 -jsfiddle.net/gz3jbcyf/2
