我的编辑按钮的ajax无法正常工作

Question

我在用户可以编辑的模式中有我的编辑按钮。 但是，更新部分不起作用。 我觉得问题出在我的控制器部分，但到目前为止，我似乎还无法独自解决。

在开发人员控制台中，ajax的响应为（0）或当我从控制器使用var_dump（$ data）时，响应为一个数组。 我不知道怎么回事。 谁能帮我？ 我已经做了近三天了。 我只是跳过而转到另一个模块。 但是我现在需要完成它。

Ajax代码

  $("#form2").submit(function(e) { var supp_code = $('#supp_codev1').val(); var address1 = $('#address1v1').val(); var address2 = $('#address2v1').val(); var country = $('#countryv1').val(); var description = $('#descriptionv1').val(); var tel_num = $('#tel_numv1').val(); var fax_num = $('#fax_numv1').val(); var contact_person = $('#contact_personv1').val(); var email = $('#emailv1').val(); var consol_agent = $('#consol_agentv1').val(); var disc1 = $('#disc1v1').val(); var disc2 = $('#disc2v1').val(); var disc3 = $('#disc3v1').val(); var disc4 = $('#disc4v1').val(); var disc5 = $('#disc5v1').val(); var last_transaction = $('#last_transactionv1').val(); var old_supplier = $('#old_supplierv1').val(); var sfm_table = $('#datatable-buttons').DataTable(); e.preventDefault(); $.ajax({ url: '<?php echo base_url(); ?>SFM/update', method: 'POST', dataType: 'JSON', data: { 'supp_codev1': supp_code, 'address1': address1, 'address2': address2, 'country': country, 'description': description, 'tel_num': tel_num, 'fax_num': fax_num, 'contact_person': contact_person, 'email': email, 'consol_agent': consol_agent, 'disc1': disc1, 'disc2': disc2, 'disc3': disc3, 'disc4': disc4, 'disc5': disc5, 'last_transaction': last_transaction, 'old_supplier': old_supplier }, success: function(data) { console.log(data); if (data) { $("#sfm_modal_edit").modal('hide'); swal("Data Edited", { icon: "success" }); } else { swal("Error", { icon: "error" }); } } }); }); 

Ajax用于填充表格

  $(document).on("click", ".editBtn", function() { var rowID = $(this).attr('id'); $.ajax({ url: '<?php echo base_url(); ?>SFM/fetch', method: "POST", dataType: "json", data: { 'id': rowID }, success: function(data) { $('#supp_codev1').val(data.fo_supp[0].SUPP_CODE); $('#address1v1').val(data.fo_supp[0].ADDRESS); $('#address2v1').val(data.fo_supp[0].ADDRESS2); $('#countryv1').val(data.fo_supp[0].COUNTRY); $('#descriptionv1').val(data.fo_supp[0].DESCRIPTION); $('#tel_numv1').val(data.fo_supp[0].TEL_NO); $('#fax_numv1').val(data.fo_supp[0].FAX_NO); $('#contact_personv1').val(data.fo_supp[0].CONTACT); $('#emailv1').val(data.fo_supp[0].EMAIL); $('#consol_agentv1').val(data.fo_supp[0].CONS_AGENT); $('#disc1v1').val(data.fo_supp[0].DISC1); $('#disc2v1').val(data.fo_supp[0].DISC2); $('#disc3v1').val(data.fo_supp[0].DISC3); $('#disc4v1').val(data.fo_supp[0].DISC4); $('#disc5v1').val(data.fo_supp[0].DISC5); $('#last_transactionv1').val(data.fo_supp[0].LAST_TRANS); $('#old_supplierv1').val(data.fo_supp[0].SUPP_CODE2); } }); }); 

调节器

  function update() { $data = array( 'SUPP_CODE'=> $this->input->post('supp_codev1'), 'ADDRESS'=> $this->input->post('address1'), 'ADDRESS2'=> $this->input->post('address2'), 'COUNTRY'=> $this->input->post('country'), 'DESCRIPTION'=> $this->input>post('description'), 'TEL_NO'=> $this->input->post('tel_num'), 'FAX_NO'=> $this->input->post('fax_num'), 'CONTACT'=> $this->input->post('contact_person'), 'EMAIL'=> $this->input->post('email'), 'CONS_AGENT'=> $this->input>post('consol_agent'), 'DISC1'=> $this->input->post('disc1'), 'DISC2'=> $this->input->post('disc2'), 'DISC3'=> $this->input->post('disc3'), 'DISC4'=> $this->input->post('disc4'), 'DISC5'=> $this->input->post('disc5'), 'LAST_TRANS'=> $this->input- >post('last_transaction'), 'SUPP_CODE2'=> $this->input->post('old_supplier') ); $supp = $this->input->post('supp_codev1'); $insertReturn2 = $this->system_model->update('fo_supp', $supp ,$data); echo json_encode($insertReturn2); }

Answer 1

找不到名为“ editBtn”的对象类

在文档中创建“ editBtn”对象？
