Question

我在如何使表搜索在javascript代码中有效时遇到问题。我有不同的情况。我正在通过ajax获取数据，所以我需要在javascript中而不是在html中添加表线程。但是现在我要搜索表格。我还编写了用于搜索的代码，但这仅在我的线程位于html中时才有效。下面是我的代码，它将为您提供清晰的视图。尝试在编辑器中阅读它，因为它更复杂:)。这是对每一列的搜索

// Javascript

$(document).ready(function() {

  $(document).ready(function() {
    $.ajaxSetup({
      headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
      }
    });
  });

  $('select[name="class_id"]').on('change', function() {
    var classID = $(this).val();
    if (classID) {

      $.ajax({

        url: '/attendance/ajax/' + classID,
        type: "GET",
        dataType: "json",
        success: function(data) {

          var markup = '';
          markup += '<tr><th style="width: 2%" class="align-middle text-center"><input type="checkbox" id="options"></th><th style="width: 2%" class="align-middle text-center">#</th> <th style="width: 15%" class="text-center">Student ID<input type="text" class="form-control" disabled></th> <th style="width: 15%" class="text-center">Student Name<input type="text" class="form-control" disabled></th> <th style="width: 15%" class="text-center">Attendance<input type="text" class="form-control" disabled></th> <th style="width: 15%" class="text-center">Date<input type="text" class="form-control" disabled></th> <th style="width: 15%;" class="align-middle text-center">Actions</th> <tr>';

Working sample。

尝试使用事件委托on()代替：

var body = $('body');

body.on('click', '.filterable .btn-filter', function() {
    alert('----1');
});

body.on('input', '.filterable .filters input', function(e) {
    alert('----2');
});
