【问题描述】:
我试图在卡片列表中显示一些元素,当我点击卡片时,我需要在该卡片上显示弹出消息。现在它出现在最上面的卡片上。但我需要它显示在我点击的卡片上。
这是我用于显示卡片元素和弹出窗口的 html 代码:
<a class="external" ng-repeat="card in cardData" ng-click="popUpFunction()">
<div class="card">
<img class="card-image" src="{{card.thumbNail_image}}" alt="">
<div class="popup">
<span class="popuptext" id="myPopup">A Simple Popup!</span>
</div>
<div class="card-infos">
<h2 class="card-title">{{card.contentDescription}}</h2>
</div>
</div>
</a>
这是css代码:
.popup {
position: relative;
display: inline-block;
cursor: pointer;
height:0px;
width:0px;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
/* The actual popup */
.popup .popuptext {
visibility: hidden;
width: 160px;
background-color: #555;
color: #fff;
text-align: center;
border-radius: 6px;
padding: 8px 0;
position: absolute;
z-index: 1;
margin-left: 80px;
}
/* Popup arrow */
.popup .popuptext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #555 transparent transparent transparent;
}
/* Toggle this class - hide and show the popup */
.popup .show {
visibility: visible;
-webkit-animation: fadeIn 1s;
animation: fadeIn 1s;
}
/* Add animation (fade in the popup) */
@-webkit-keyframes fadeIn {
from {opacity: 0;}
to {opacity: 1;}
}
@keyframes fadeIn {
from {opacity: 0;}
to {opacity:1 ;}
}
这是js代码:
$scope.popUpFunction = function () {
var popup = document.getElementById("myPopup");
popup.classList.toggle("show");
}
