Bootstrap Modal不起作用
[英]Bootstrap Modal isn't working
問題描述
我正在嘗試在窗口顯示時加載模態，但我唯一看到的是背景內容不可見。 我也在嘗試使用會話存儲。
jQuery(document).ready(function(){ // Start // sessionStorage.getItem('key'); if (sessionStorage.getItem("story") !== 'true') { // sessionStorage.setItem('key', 'value'); pair sessionStorage.setItem("story", "true"); // Calling the bootstrap modal $("#myModal").modal('show'); } // End // Do not include the code below, it is just for the 'Reset Session' button in the viewport. // This is same as closing the browser tab. $('#reset-session').on('click',function(){ sessionStorage.setItem('story',''); }); });
<div class="modal" tabindex="-1" role="dialog" id="myModal"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title">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"> <p>Modal body text goes here.</p> </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>

這是一個工作示例。 確保使用以下命令正確加載了Bootstrap ：
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">

編輯 -代碼段：
$(document).ready(function(){ // Calling the bootstrap modal $("#myModal").modal('show'); });

我嘗試通過使用Bootstrap單擊圖像來實現模態，但是它不起作用
