jquery - 使用 jQuery replaceWith(); 在特定班级

Question

我有一个通过 PHP/MySQL 填充的联系人表。每个联系人都在自己的行中，其类名是“line”加上行号，例如“line01”或“line02”。

我有一个 jQuery 模式对话框，用于添加新联系人、编辑当前联系人和删除联系人。我.replaceWith()用于编辑和.append();添加新联系人。我现在的挑战是让编辑功能正常工作，以便它只替换<div>正在编辑的行，而不是所有行。

如何选择要替换的特定元素，或确保被替换的行与正在编辑的行具有相同的 ID？应该很简单，但我只是无法让它正常工作。帮助表示赞赏！

这是我到目前为止的代码：

$("#contact-dialog").dialog({
    autoOpen: false,
    width: 600,
    modal: true,
    buttons: {
            "Add Contact": function() {
                var bValid = true;
                allFields.removeClass( "ui-state-error" );

                bValid = bValid && checkLength( contact_first_name, "first name", 2, 64 );
                bValid = bValid && checkLength( contact_last_name, "last name", 2, 64 );
                bValid = bValid && checkLength( title, "title", 1, 64 );
                bValid = bValid && checkLength( phone, "phone", 6, 30 );
                bValid = bValid && checkLength( email_address, "email_address", 5, 128 );       

                /* Handle edit function */                  
                if (crow.val().length > 0) {
                    if ( bValid ) {
                        if (contact_count % 2) {
                          //$( "#contacts" ).html(

编辑：这是代码edit_contact()：

function edit_contact(contact_line, cid) {
    // $('#contact-dialog-link').val('edit');
    $('#contact-dialog-id').val(cid);
    $('#contact-first-name').val($('.line'+contact_line+' #contact-first-name'+contact_line).val());
    $('#contact-last-name').val($('.line'+contact_line+' #contact-last-name'+contact_line).val());
    $('#title').val($('.line'+contact_line+' #title'+contact_line).val());
    $('#cphone').val($('.line'+contact_line+' #cphone'+contact_line).val());
    $('#email-address').val($('.line'+contact_line+' #email-address'+contact_line).val());
    $('#twitter').val($('.line'+contact_line+' #twitter'+contact_line).val());
    $('#facebook').val($('.line'+contact_line+' #facebook'+contact_line).val());
    $('#linkedin').val($('.line'+contact_line+' #linkedin'+contact_line).val());
    $('#contact-update').val(contact_line);
    $('#contact-dialog-link').trigger('click');
}

编辑：这是处理保存功能的 PHP：

if ($_POST && $_POST['type'] == 'add-to-contacts') {
$fid = $_SESSION['facility_current'];
if ($_POST['input'] == 'edit') {
//  if ($_POST['contact-update'] == ''){
    $dbQuery = sprintf("UPDATE facility_contacts SET fid=%d, first_name='%s', last_name='%s', title='%s', phone='%s', email_address='%s', twitter='%s', facebook='%s', linkedin='%s' WHERE cid = %d;", $fid,$_POST['first_name'],$_POST['last_name'],$_POST['title'],$_POST['phone'],$_POST['email_address'],$_POST['twitter'],$_POST['facebook'],$_POST['linkedin'],$_POST['cid']);
} else {
    $dbQuery = sprintf("INSERT INTO facility_contacts (fid, first_name, last_name, title, phone, email_address, twitter, facebook, linkedin) VALUES (%d,'%s','%s','%s','%s','%s','%s','%s','%s');", $fid,$_POST['first_name'],$_POST['last_name'],$_POST['title'],$_POST['phone'],$_POST['email_address'],$_POST['twitter'],$_POST['facebook'],$_POST['linkedin']);
}
$dbResult = $dbc->query($dbQuery,__FILE__,__LINE__);
unapprove_proof_status();
echo ($dbResult) ? true : false;
exit;

I'm not sure if your selectors for $('#contact-first-name').val() are specific enough. You may need something like $('#contact-first-name', '.line'+contact_line).val() to select the contact input item within a specific <div class="line'+contact_count+'">. I would try this:

$("#contact-dialog").dialog({
    autoOpen: false,
    width: 600,
    modal: true,
    buttons: {
            "Add Contact": function() {
                var bValid = true;
                allFields.removeClass( "ui-state-error" );

                bValid = bValid && checkLength( contact_first_name, "first name", 2, 64 );
                bValid = bValid && checkLength( contact_last_name, "last name", 2, 64 );
                bValid = bValid && checkLength( title, "title", 1, 64 );
                bValid = bValid && checkLength( phone, "phone", 6, 30 );
                bValid = bValid && checkLength( email_address, "email_address", 5, 128 );       

                var alt = contact_count % 2 ? ' gray': '';

                /* Handle edit function */                  
                if (crow.val().length > 0) {
                    if ( bValid ) {
                         $('.line'+contact_count).replaceWith(
                            '<div class="action' + alt + '">' +

function edit_contact(contact_line, cid) {
    $('#contact-dialog-id').val(cid);
    $('#contact-first-name', '.line'+contact_line).val($('.line'+contact_line+' #contact-first-name'+contact_line).val());
    $('#contact-last-name', '.line'+contact_line).val($('.line'+contact_line+' #contact-last-name'+contact_line).val());
    $('#title', '.line'+contact_line).val($('.line'+contact_line+' #title'+contact_line).val());
    $('#cphone', '.line'+contact_line).val($('.line'+contact_line+' #cphone'+contact_line).val());
    $('#email-address', '.line'+contact_line).val($('.line'+contact_line+' #email-address'+contact_line).val());
    $('#twitter', '.line'+contact_line).val($('.line'+contact_line+' #twitter'+contact_line).val());
    $('#facebook', '.line'+contact_line).val($('.line'+contact_line+' #facebook'+contact_line).val());
    $('#linkedin', '.line'+contact_line).val($('.line'+contact_line+' #linkedin'+contact_line).val());
    $('#contact-update').val(contact_line);
    $('#contact-dialog-link').trigger('click');
}

By using $('#itemToUpdate', '#divWhereItLives'), you can set a context for where to find the item to update - see http://api.jquery.com/jQuery/

Edit: should have been var alt = contact_count % 2 ? ' gray': '';. Sorry

jquery - 使用 jQuery replaceWith(); 在特定班级
