Javascript - 点击图像时弹出信息框

标签 javascript jquery html

我有一些图像，我需要在它们上有一个点击事件，在每个图像上显示一个信息框。

   $('.show-infobox').on('click', function() {
    // Hide all infoboxes to prevent multiple showing at once
    $('.infobox').addClass('hidden');
    
    // Show infobox background
    $('.infobox-container').removeClass('hidden');
    
    // Show infobox matching last part of ID
    $('#' + this.id.replace('show')).removeClass('hidden');
});

$('.hide-infobox').on('click', function() {
    // Manually hide all infoboxes and background
    $('.infobox-container').addClass('hidden');
    $('.infobox').addClass('hidden');
}).children().on('click', function() {
    return false; 
});
@charset "utf-8";
.container {
	height: 800px;
	width: 1000px;
	margin: 0;
}
body {
    padding:0px;
    width:100%;
}

header
{
	top: 11px;
	width: 100%;
	padding-bottom: 10px;
	
	}
	#wrapper{
	margin-left: auto;
	margin-right: auto;
	width: 1000px;
	}
	
	ol {
	list-style-type: upper-roman;
	
	}
	
H3 {
font-size:16px;
text-shadow: 0px 0px 5px grey;
}	
	
.mainBox
{
	background-color: #F0F0F0;
	width: 700px;
	box-shadow: 0px 0px 15px grey;
	top: 310px;
	border-radius: 20px;
	padding-top: 30px;
	padding-right: 50px;
	padding-left: 50px;
	}

	

.container nav ul {

     cursor:pointer;  
}
.imagePack
{
	float:left;
	height: 300px;
	width: 200px;
	border-style:solid;
}
img.staff {
    cursor: pointer;
    opacity: 0.4;
    filter: alpha(opacity=40); /* For IE8 and earlier */
}

img.staff:hover {
    opacity: 1.0;
    filter: alpha(opacity=100); /* For IE8 and earlier */
}
	
.infobox-container {
    background: rgba(0, 0, 0, .2);
    width: 100%;
    height: 100%;
    position: absolute;
    display: flex;

.show-infobox {

.hidden {
    display: none;

目前我只是想在简单的文本上调出信息框，看看它是否有效。但事实并非如此。只有容器出现，没有实际的信息框。

最佳答案

我只是展示如何做到这一点。您仍然需要大量更改代码。 我建议您通过 w3schools 以获得更好的理解。

这是DEMO 

$(".infobox-container, .infobox").hide();

$(".show-infobox").click(function()
{
var curId = this.id;
if(curId == "show1")
    {
        $(".infobox-container, #infobox-1").fadeIn(100);
    }
if(curId == "show2")
    {
        $(".infobox-container, #infobox-2").fadeIn(100);
    }
});

$(".hide-infobox").click(function()
{  
    $(".infobox-container, .infobox").fadeOut();
});
@charset"utf-8";
 .container {
    height: 800px;
    width: 1000px;
    margin: 0;
}
body {
    padding:0px;
    width:100%;
}
header {
    top: 11px;
    width: 100%;
    padding-bottom: 10px;
}
#wrapper {
    margin-left: auto;
    margin-right: auto;
    width: 1000px;
}
ol {
    list-style-type: upper-roman;
}
H3 {
