示例代码
01
JQ实现
代码语言:javascript复制$(".ion-ios-search").click(function() {
if (!$(".search").hasClass("active")) {
$(".search").addClass("active");
}
})
$(".ion-ios-close-empty").click(function() {
$(".search").removeClass("active");
})
JQ的实现主要是操作DOM,$选择器,判断一个元素里面有没有class类,可以用hasClass方法
给一个元素添加类名使用addClass('类名'),而移除元素的类名使用removeClass('类名')
02
Js实现
代码语言:javascript复制var ionIosEarch = document.querySelector(".ion-ios-search");
var ionIosCloseEmpty = document.querySelector(".ion-ios-close-empty");
var searchDom = document.querySelector(".search");
ionIosEarch.addEventListener("click", function() {
searchDom.classList.add('active');
}
ionIosCloseEmpty.addEventListener("click", function() {
searchDom.classList.remove('active');
}
原生Js,主要是获取元素,使用document.querySelector()获取元素,给元素添加类名使用元素.classList.add('类名')
而移除元素的类名使用元素.classList.remove('类名')
03
Vue实现
代码语言:javascript复制<template>
<div>
<div class='background'>
<div class='main'>
<div :class='{active: isActive}' class="search">
<input placeholder='Search' type='text'>
<i @click="handleSearch" class='icon el-icon-search ion-ios-search'></i>
<i @click="handleClose" class='icon el-icon-close ion-ios-close-empty'></i>
</div>
<div class='results'></div>
</div>
</div>
</div>
</template>
<script>
export default {
name: "transformMatrix3d",
data(){
return {
isActive:false,
}
},
methods: {
handleSearch() {
this.isActive = true;
},
handleClose() {
this.isActive = false;
}
}
}
</script>
<style lang="scss" scoped>

@keyframes hide {

}
100% {
transform: rotate(0deg) matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1);

transform: rotate(10deg) matrix3d(1.1, 0, 0, 0, 0, 1.1, 0, 0, 0, 0, 1, 0, 0, 10, 1, 1);
}
80% {
transform: rotate(-5deg) matrix3d(1, 0.1, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1);
}
100% {
transform: matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 1, 1);
}
}
</style>
在Vue里面,主要逻辑控制里,是通过data下面的isActive的boolean值,动态添加active类型
在模板里动态绑定class,实现逻辑的控制
利用transform:matrix3d()矩阵变换和动画变换
