Vue利用flex布局实现TV端城市列表
vue中城市列表和搜索很常见，这篇博客就来说说咋实现搜索和城市列表
1.实现搜索布局代码：
<div class="search-bar">
<input class="search-input" v-model="citySearchResult" :placeholder="searchDefault" :key="searchTitle"
@endEditing="endEditing" :focusable="true" ref="searchInput" :duplicateParentState="true"
:enableFocusBorder="true"/>
<img class="index-root-search-image-view-css" :src="searchIcon">
<span class="index-root-search-text-view-css" ref="textViewCity">{{searchDefaultKeyWord}}</span>
</div>
2.搜索布局css样式代码：
.search-bar-root {
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
margin-top: 140px;
}.index-root-search-title-css {
flex-direction: column;
align-items: center;
justify-content: center;
margin-bottom: 40px;
}.search-bar-root .search-bar {
background-color: #ffffff;
width: 1000px;
height: 100px;
display: flex;
justify-content: center;
border-radius: 8px;
}.search-input {
width: 780px;
border-radius: 8px;
font-size: 36px;
font-family: PingFangSC-Regular, PingFang SC;
font-weight: 400;
color: #000000;
margin-left: 40px;
text-indent: 40px;
}.index-root-search-image-view-css {
position: absolute;
width: 32px;
height: 32px;
top: 35px;
bottom: 35px;
right: 0;
margin-right: 102px;
text-align: center;
}.index-root-search-flex-view-css {
display: flex;
flex-wrap: wrap;
flex-direction: row;
width: 1450px;
margin-left: 245px;
margin-right: 245px;
margin-top: 40px;
}.index-root-search-text-view-css {
font-size: 30px;
font-family: PingFangSC-Regular, PingFang SC;
color: #000000;
text-align: center;
font-weight: 400;
top: 0;
bottom: 0;
right: 0;
position: absolute;
margin-right: 30px;
}.index-root-search-title-text-view-css {
font-size: 70px;
font-family: PingFangSC-Regular, PingFang SC;
color: #ffffff;
text-align: center;
opacity: 1.0;
}.search-city-button-view-css {
width: 270px;
height: 100px;
background-color: rgba(0, 0, 0, .1);
margin-right: 20px;
margin-top: 40px;
border-radius: 11px;
border-width: 2px;
border-color: rgba(255, 255, 255, 0.1);
focus-background-color: #fff;
}.search-city-button-view-css .city-sel-box {
border-width: 2px;
border-color: #32C5FF;
}
3.城市列表布局代码：
<div class="index-root-search-flex-view-css" :clipChildren="false" ref="citySearch">
<div class="search-city-button-view-css"
v-for="(item,cityId) in hotCity" :focusable="true"
:key="cityId"
:ref="`hotRef${cityId}`" @focus="onFocus" :clipChildren="false">
<div class="icon-location-reactive" ref="searchLocation" :duplicateParentState="true" style="visibility: visible;margin-right: 20px" v-if="showHot && cityId===0">
<img src="@/assets/location.png" alt="" class="icon-location" showOnState="normal">
<img src="@/assets/location_hot_focus.png" alt="" class="icon-location" showOnState="focused">
</div>
<span class="search-city-hot-text-iew-css" :duplicateParentState="true" showOnState="focused"
ref="searchHotSelected"
:style="{focusColor: focusHotTextColor,fontSize: textFontSize,fontWeight: textFontWeight,}">{{item.cityName}}</span>
</div>
4.城市列表css样式代码：
.index-root-search-flex-view-css {
display: flex;
flex-wrap: wrap;
flex-direction: row;
width: 1450px;
margin-left: 245px;
margin-right: 245px;
margin-top: 40px;
}.index-root-search-text-view-css {
font-size: 30px;
font-family: PingFangSC-Regular, PingFang SC;
color: #000000;
text-align: center;
font-weight: 400;
top: 0;
bottom: 0;
right: 0;
position: absolute;
margin-right: 30px;
}.index-root-search-title-text-view-css {
font-size: 70px;
font-family: PingFangSC-Regular, PingFang SC;
color: #ffffff;
text-align: center;
opacity: 1.0;
}.search-city-button-view-css {
width: 270px;
height: 100px;
background-color: rgba(0, 0, 0, .1);
margin-right: 20px;
margin-top: 40px;
border-radius: 11px;
border-width: 2px;
border-color: rgba(255, 255, 255, 0.1);
focus-background-color: #fff;
}.search-city-button-view-css .city-sel-box {
border-width: 2px;
border-color: #32C5FF;
}.icon-location-reactive {
position: absolute;
width: 26px;
height: 34px;
margin-left: 60px;
margin-top: 30px;
margin-bottom: 30px;
}.icon-location {
width: 26px;
height: 34px;
position: absolute;
left: 0;
top: 0;
z-index: 9;
}.search-city-hot-text-iew-css {
width: 270px;
height: 100px;
background-color: rgba(50, 197, 255, 0.1);
border-radius: 11px;
border: 2px solid #32C5FF;
font-size: 36px;
font-family: PingFangSC-Regular, PingFang SC;
text-align: center;
color: white;
}.search-city-empty {
margin-top: 40px;
width: 425px;
display: flex;
align-items: center;
justify-content: center;
flex-direction: column;
margin-left: 535px;
}.search-city-empty .icon-no-connect {
width: 425px;
height: 307px;
}.search-city-empty .empty-txt {
font-size: 32px;
font-family: PingFangSC-Light, PingFang SC;
font-weight: 300;
color: #FFFFFF;
margin-top: 60px;
}
5.城市列表获取焦点的事件：
主要是在div设置:focusable="true"和@focus="onFocus"
<div class="search-city-button-view-css"
v-for="(item,cityId) in hotCity" :focusable="true"
:key="cityId"
:ref="`hotRef${cityId}`" @focus="onFocus" :clipChildren="false">
<div class="icon-location-reactive" ref="searchLocation" :duplicateParentState="true" style="visibility: visible;margin-right: 20px" v-if="showHot && cityId===0">
<img src="@/assets/location.png" alt="" class="icon-location" showOnState="normal">
<img src="@/assets/location_hot_focus.png" alt="" class="icon-location" showOnState="focused">
</div>
6.设置焦点背景颜色和字体效果：
主要是设置:duplicateParentState="true"当文本获得焦点时颜色不受父布局影响，还可以设置焦点放大和带边框效果
:enableFocusBorder="true"//设置获得焦点时的边框
:focusScale="1.0"//设置焦点放大时的倍数
焦点效果的样式：:style="{focusColor: focusHotTextColor,fontSize: textFontSize,fontWeight: textFontWeight,}
<span class="search-city-hot-text-iew-css" :duplicateParentState="true" showOnState="focused"
ref="searchHotSelected"
:style="{focusColor: focusHotTextColor,fontSize: textFontSize,fontWeight: textFontWeight,}">{{item.cityName}}</span>
7.搜索框输入事件：
//输入内容之后请求城市列表接口刷新数据
endEditing(e) {
console.log("--resultData--", this.citySearchResult)
},
8.搜索框获取焦点的事件：
onFocus(e) {
this.focused = e.isFocused;
this.$emit("onButtonFocused", e.isFocused);
},
9.默认弹出TV软键盘：
mounted() {
this.hotCity = hotCity;
this.showHot = true;
this.pageLoading = true
//弹出软键盘
this.$refs.searchInput.focus()
//搜索框默认获取焦点
this.setHideLoading()
},
10.完整代码如下：

<div class="index-root-search-view-css" :clipChildren="false">
<img class="search-background-view-css" :src="searchImageData"/>
<div class="search-bar-root">
