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

- :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>
- <div class="index-root-search-flex-view-css" :clipChildren="false" ref="citySearch">

- :style="{focusColor: focusHotTextColor,fontSize: textFontSize,fontWeight: textFontWeight,}">{{item.cityName}}</span>
- </div>
- <div class="search-city-empty" v-if="hotCity.length === 0">
