jQuery编辑后如何更新数据表行? [英] jquery how to update datatable row after edit?

问题描述

当我在编辑模式中编辑某些字段时，我正在尝试更新 datatable .下面是我的 modal ，添加行和 btnSubmit 函数以获取已编辑的字段.

I am trying to update my datatable when I edit some fields in my edit modal. Below is my modal, add row and btnSubmit function to get the edited fields.

 <div class="modal" id="myModal">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title">Close</h4>
            </div>
            <div class="modal-body">
                <p>
                    <label for="name">Name:</label>
                    <input type="text" id="name1" placeholder="Name">
                </p>
                <p>
                    <label for="name">E-mail#:</label>
                    <input type="email" class="input-sm" id="email1" placeholder="Email">
                </p>
                <p>
                    <label for="name">Contact#:</label>
                    <input type="text" class="input-sm" id="cno1" placeholder="Contact">
                </p>
                <p>
                    <label for="name">Date Of Birth:</label>
                    <input type="date" class="input-sm" id="dob1" placeholder="DOB">
                </p>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" id="btnsubmit" class="btn btn-primary">Save changes</button>
            </div>
        </div>
        <!-- /.modal-content -->
    </div>
    <!-- /.modal-dialog -->
</div>

$('.add-row').on('click', function() {
            name = $("#name").val();
            email = $("#email").val();
            cno = $("#cno").val();
            bdy = $("#bday").val();
            
            t.row.add([
                name,
                email,
                cno,
                bdy,
                "<button class ='btn btn-danger del'>Delete</button>" + " " + "<button class='btn btn-warning upd'>Edit</button>"





            ]).draw(false);
            $("#name").val('');
            $("#email").val('');
            $("#cno").val('');
            $("#bday").val('');

        });
        

$("#btnsubmit").click(function () {
                var new_name = $("#name1").val();
                var new_email = $("email1").val();
                var new_cno = $("#cno1").val();
                var new_dob = $("#dob1").val();
                
            
                $("#myModal").modal("hide");
            })

更新1

我试图制作一个数组，然后绘制它.

I have tried to make an array and then draw it.

//save change button click evnet
         $("#btnsubmit").click(function () {
            var table = $('#example').DataTable();
            var tableRow = $(this).parents('tr');
            
                var new_name = $("#name1").val();
                var new_email = $("email1").val();
                var new_cno = $("#cno1").val();
                var new_dob = $("#dob1").val();
                var rData = [
                    
                        new_name,
                        new_email,
                        new_cno,
                        new_dob,
                        
                    
                ];
                table
                .row(tableRow)
                .data(rData)
                .draw();
                $("#myModal").modal("hide");
            });

现在我出错了

> datatable.js:430 Uncaught TypeError: Cannot set property '_aData' of undefined
  at D.<anonymous> (datatable.js:430)
    at D.data (datatable.js:371)
    at HTMLButtonElement.<anonymous> (form1_datatable.html:194)

更新2

因此，在做出一些努力之后，我终于能够更新该行.但是现在我遇到了一个问题.每当我尝试更新它时，它总是更新第一行.下面是我的保存按钮代码

So after doing some efforts I am finally able to update the row. But now I am getting an issue. Whenever I tried to update it, it always updates the 1st row. Below is my code for save button

//save change button click evnet
         $("#btnsubmit").on('click',function () {
            var table = $('#example').DataTable();
            var tableRow = $(this).closest('tr');
            
                var new_name = $("#name1").val();
                var new_email = $("#email1").val();
                var new_cno = $("#cno1").val();
                var new_dob = $("#dob1").val();

                var rData = [
                    
                        new_name,
                        new_email,
                        new_cno,
                        new_dob,
                        "<button class ='btn btn-danger del'>Delete</button>" + " " + "<button class='btn btn-warning upd'>Edit</button>"
                    
                ];
                console.log(tableRow);
                 table
                 .row()
                 .data(rData)
                 .draw();
                 $("#myModal").modal("hide");
            });

更新3

按照 Vahap 的答案，我更新了代码

As per Vahap answer I updated my code

$('.add-row').on('click', function() {
            id = 0;
            name = $('#name').val();
            email = $('#email').val();
            cno = $('#cno').val();
            bdy = $('#bday').val();
            
            t.row.add([
                name,
                email,
                cno,
                bdy,
                '<button class ="btn btn-danger del">Delete</button>' + '' + '<button class="btn btn-warning upd" data-id="'+$('#example').DataTable().rows().count()+'">Edit</button>'





            ]).draw(false);
            $("#name").val('');
            $("#email").val('');
            $("#cno").val('');
            $("#bday").val('');

        });

//save change button click evnet
         $("#btnsubmit").on('click',function (e) {
             // Prevent event propagation
            e.stopPropagation();
            var new_name = $("#name1").val();
                var new_email = $("#email1").val();
                var new_cno = $("#cno1").val();
                var new_dob = $("#dob1").val();
              
            const id = $(this).attr("data-id");
            console.log(id);
            var temp = $('#example').DataTable().row(id).data();
            temp[0] = new_name;
            temp[1] = new_email;
            temp[2] = new_cno;
            temp[3] = new_dob;
            $('#example').DataTable().row(id).data( temp ).draw(false);
       
                $("#myModal").modal("hide");
            });

但是它仍然总是更新第一行.我也得到 undefined ，因为 const id = $(this).attr("data-id");console.log(id);

But it still updating the 1st row always. Also I am getting undefined for const id = $(this).attr("data-id"); console.log(id);

我能够添加新行，将其删除并打开用于编辑它的模式.现在我想问的是，如何将更新的值设置到当前的 datatable 行中?任何帮助将不胜感激.

I am able to add a new row, delete it and open a modal for editing it. Now I want to ask is that how can I set the updated values into my current datatable row? Any help would be highly appreciated.
