如何在Laravel中的javascript中使搜索工作 [英] How to make search work in javascript in laravel

问题描述

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

I have a problem in how to make table search working in the javascript code. I have a different scenario. I am getting data through ajax So I need to add table thread in the javascript rather than in the html. But now I want a search for the table. I write also code for that to search but that's only working when my thread is in the html. Below is my code and it will give you a clear view. Try to read it in the editor because its a more complicated :). It is a search for each column

//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>';

          $.each(data, function(key, value) {

            markup += '<tr> <td><input class="checkBoxes" type="checkbox" name="checkBoxArray[]"></td> <td><input type="hidden" value="' + value.id + '" name="id[]">' + value.id + '</td> <td><input type="hidden" value="' + value.student_id + '" name="student_id[]">' + value.student_id + '</td> <td><input type="hidden" value="' + value.first_name + '" name="first_name[]"><input type="hidden" value="' + value.last_name + '" name="last_name[]">' + value.first_name + ' ' + value.last_name + '<td><input type="hidden" value="' + value.attendance + '" name="attendance[]">' + value.attendance + '</td>' + '<td><input type="hidden" value="' + value.created_at + '" name="created_at[]">' + value.created_at + '</td>' + '<td style=" width=12%" class="text-center"> <a><button title="Edit" class="btn btn-outline-primary"><span class="fas fa-pencil-alt"></span></button></a> </td>' + '</td> <tr>';

          });
          $('table[id="studentsData"]').html(markup);
        }
      });
    }
  });
});

推荐答案

工作示例.

Working sample.

尝试使用事件委托on()代替:

Try to use event delegation on() instead like :

var body = $('body');

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

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