Implementing card flipping effects in WeChat mini programs
In WeChat mini programs, realizing card flipping effects is a common animation effect that can improve user experience and The attractiveness of interface interaction. The following will introduce in detail how to implement the special effect of card flipping in the WeChat applet and provide relevant code examples.
First, you need to define two card elements in the page layout file of the mini program, one for displaying the front content and one for displaying the back content. The specific sample code is as follows:
<!-- 正面内容 --> <text>正面内容</text>
<!-- 背面内容 --> <text>背面内容</text>
at In the style file, define the corresponding style for the card element, including width, height, background color and other attributes. The specific sample code is as follows:
/ index.wxss /
.card {
width: 200rpx;
height: 300rpx;
perspective: 1000rpx; / Set the observer position of the 3D effect/
}
. card-front,
.card-back {
position: absolute;
width: 100%;
height: 100%;
backface-visibility: hidden; / Hide the back Invisible/
transition: transform 0.5s; / Set the transition effect, the duration is 0.5 seconds/
}
.card-front {
background -color: #ff0000;
}
.card-back {
background-color: #0000ff;
transform: rotateY(-180deg); / Initial flip of the back 180 degree hiding/
}
Next, in the script file of the page, write the corresponding code logic to achieve the flipping effect of the card. The specific example code is as follows:
// index.js
Page({
data: {
isFlipped: false // 卡片是否翻转变量
},
flipCard: function() {
var isFlipped = this.data.isFlipped; this.setData({ isFlipped: !isFlipped });
}
})
Code explanation:
- Use the isFlipped variable to control the flipping state of the card. The initial value is false, which means the front content is displayed normally;
- flipCard The function is used to realize the flipping effect of the card. It changes the value of isFlipped through the setData method to control the flipping state of the card;
Finally, bind the click event in the page layout file to trigger the flipping effect. Specifically The sample code is as follows:
<view class="card-front"> <!-- 正面内容 --> <text>正面内容</text> </view> <view class="card-back"> <!-- 背面内容 --> <text>背面内容</text> </view>
< ;/view>
In the style file, set the flip animation effect for the card element. The specific sample code is as follows:
/ index.wxss /
.flipped .card-front {
transform: rotateY(180deg); / Flip front 180 degrees to hide /
}
.flipped .card-back {
transform: rotateY(0deg); / Flip the back back to the front for display/
}
Through the above code, we can The special effect of card flipping is implemented in the program. When the user clicks the "Click to Flip" button, the card will flip from the front content to the back content and be presented to the user through an animated transition.
Summary:
By defining the front and back elements of the card, and combining the code logic in the style file and script file, we can achieve the special effect of card flipping in the WeChat applet. This interactive effect can enhance the user experience and make the interface more vivid and interesting.
