Question

我在HTML上创建了2个按钮，按下按钮，它将打开一个模态屏幕。这个eaxmple有两个按钮，但我的目标是一个页面可以有多个按钮。按 X 时，它会关闭模态屏幕。但是，如果你按压模态区域外，它也应该关闭它。这对两个按钮都不起作用。

任何帮助都会受到赞赏，或者如果您知道更简单/更好的方式来使用模态屏幕。： - ）

你有两个window.onclick = function(event)第二个覆盖第一个。

所以你真的应该只有一个window.onclick处理程序：

<!DOCTYPE html>
<html>
<head>
<style>
/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

/* Modal Content */
.modal-content {
    background-color: #fefefe;
    margin: auto;
    padding: 20px;
    border: 1px solid #888;
    width: 80%;
}

/* The Close Button */
.close {
    color: #aaaaaa;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: #000;
    text-decoration: none;
    cursor: pointer;
}
</style>
</head>
<body>
