<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>modal</title> <script type="text/javascript" src="jquery-3.3.1.min.js"></script> <script type="text/javascript" src="bootstrap-4.0.0-dist/js/bootstrap.bundle.min.js"></script> <link rel="stylesheet" type="text/css" href="bootstrap-4.0.0-dist/css/bootstrap.min.css"> </head> <body> <!-- css自带弹窗处理 --> <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"> 弹窗1 </button> <!-- Modal --> <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> </div> <div class="modal-body"> ... </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div> </body> </html>
自己使用jquery控制弹窗
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>modal</title> <script type="text/javascript" src="jquery-3.3.1.min.js"></script> <script type="text/javascript" src="bootstrap-4.0.0-dist/js/bootstrap.bundle.min.js"></script> <link rel="stylesheet" type="text/css" href="bootstrap-4.0.0-dist/css/bootstrap.min.css"> </head> <body> <!-- css自带弹窗处理 --> <!-- <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal"> 弹窗1 </button> --> <!-- js控制弹窗 --> <button id="myModal" class="btn btn-info">弹窗2</button> <!-- Modal --> <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="exampleModalLabel">Modal title</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> </div> <div class="modal-body"> ... </div> <div class="modal-footer"> <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button> <button type="button" class="btn btn-primary">Save changes</button> </div> </div> </div> </div> <script type="text/javascript"> $('#myModal').on('click', function () { $('#exampleModal').modal('show'); }) </script> </body> </html>
