“弹出框”是什么意思?浏览器或文档中的元素发出警报?
对于提醒:您需要像这样使用JavaScript:
<button onclick="alert('Message goes here');"></button>
对于文档中的box元素:您也应该使用JavaScript,如下所示:
function popBox(id) {
if (document.getElementById("pop" + id)) return;
var myBox = document.createElement("div");
// Style your div element as you wish, with JS, in <style></style>, in an external stylesheet
myBox.id = "pop" + id;
myBox.innerHTML = "Hey.";
document.getElementById("imgwrap").appendChild(myBox);
}
整个文件:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<style>
.imagewrap {
display: inline-block;
position: relative;
z-index: 1;
}
#button1 {
position: absolute;
bottom: 0;
left: 25%;
}
#button2 {
position: absolute;
bottom: 0;
right: 0;
}
#button3 {
position: absolute;
right: 50%;
top: 50%;
}
#pop1, #pop2, #pop3 {
position: absolute;
z-index: 3;
width: 50px;
height: 50px;
}
#pop1 {
right: 10%;
top: 10%;
background-color: #FFF;
}
#pop2 {
right: 20%;
top: 20%;
background-color: #888;
}
#pop3 {
right: 30%;
left: 30%;
background-color: #000;
}
</style>
</head>
<body>
<div class="imagewrap" id="imgwrap">
<img src="https://www.google.com/logos/2012/opening_ceremony-2012-hp.jpg" />
<div id="pop">
<button id="button1" onclick="popBox(1);">אודות</button>
<button id="button2" onclick="popBox(2);">ערוץ היוטיוב</button>
<button id="button3" onclick="popBox(3);">פייסבוק</button>
</div>
</div>
<script>
function popBox(id) {
if (document.getElementById("pop" + id)) return;
var myBox = document.createElement("div");
// Style your div element as you wish, with JS, in <style></style>, in an external stylesheet
myBox.id = "pop" + id;
myBox.innerHTML = "Hey.";
document.getElementById("imgwrap").appendChild(myBox);
}
</script>
</body>
</html>
我推荐使用button
元素而不是input
,因为它不是表单,而是按钮。
编辑:
我刚刚看到你的评论说你想使用 only CSS 。您至少需要最少的JavaScript。我们的想法是创建您的div
元素,根据需要设置样式,然后添加display: none;
。然后,您必须使用JavaScript将其更改为display: block;
:
<button id="button1" onclick="document.getElementById('pop1').style.display = 'block';">etc</button>
