Vue利用flex佈局實現TV端城市清單
vue中城市清單和搜尋很常見,這篇部落格就來說說咋實現搜尋和城市列表
1.實作搜尋佈局代碼:
<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" alt="一文詳解Vue+flex佈局實現TV端城市列表" > <span class="index-root-search-text-view-css" ref="textViewCity">{{searchDefaultKeyWord}}</span> </div>
2.搜尋佈局css樣式程式碼:
.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.城市清單佈局代碼:
<div> <div> <div> <img alt="一文詳解Vue+flex佈局實現TV端城市列表" > <img alt="一文詳解Vue+flex佈局實現TV端城市列表" > </div> <span>{{item.cityName}}</span> </div> <p><strong>4.城市清單css樣式代碼:</strong></p> <pre class="brush:php;toolbar:false">.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.城市清單取得焦點的事件:
主要是在div設定:focusable="true"和@focus="onFocus"
<div> <div> <img alt="一文詳解Vue+flex佈局實現TV端城市列表" > <img alt="一文詳解Vue+flex佈局實現TV端城市列表" > </div> <p><strong>6.設定焦點背景顏色和字體效果:</strong></p> <p>主要是設定:duplicateParentState="true"當文字獲得焦點時顏色不受父佈局影響,還可以設定焦點放大和帶邊框效果</p> <pre class="brush:php;toolbar:false">: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
焦點效果的樣式: :style="{focusColor: focusHotTextColor,fontSize: textFontSize,fontWeight: textFontWeight,}
<span>{{item.cityName}}</span>
7.搜尋框輸入事件:
//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.搜尋框取得焦點的事件:
onFocus(e) { this.focused = e.isFocused; this.$emit("onButtonFocused", e.isFocused); },
9.預設彈出TV軟鍵盤:
mounted() { this.hotCity = hotCity; this.showHot = true; this.pageLoading = true //弹出软键盘 this.$refs.searchInput.focus() //搜索框默认获取焦点 this.setHideLoading() },
10.完整程式碼如下:
<script>import searchImage from "@/assets/search_focus.png";import searchBackGroundImage from "@/assets/index-bg-qing.jpg";import {hotCity} from '@/views/contsants';import {ESLaunchManager} from "@extscreen/es-core";export default { name: "city_list", props: { searchKeyWord: { type: String, default: '', }, focusTextColor: { type: String, default: '#000000' }, focusHotTextColor: { type: String, default: '#00EFFF' }, textColor: { type: String, default: '#FFFFFF' }, textFontSize: { type: String, default: '30px' }, textFontWeight: { type: Number, default: 400 }, focusBackground: { orientation: 'TL_BR',//TOP_BOTTOM,TR_BL, RIGHT_LEFT, BR_TL, BOTTOM_TOP,BL_TR,LEFT_RIGHT,TL_BR, cornerRadius: [40, 40, 40, 40], normal: ['#00000000', '#00000000'], focused: ['#F5F5F5', '#F5F5F5'], }, }, data() { return { pageLoading: false, text: 'search city', search: '', searchIcon: searchImage, searchImageData: searchBackGroundImage, searchTitle: "切换城市", searchDefaultKeyWord: '搜索', searchDefault: '请输入城市名称首字母或全拼', focusColor: '#f5f5f5', citySearchResult: "", hotCity: [], cityName: "", cityId: "", showHot: true, params: '', } }, activated() { }, deactivated() { this.resetModel() }, mounted() { this.hotCity = hotCity; this.showHot = true; this.pageLoading = true //弹出软键盘 this.$refs.searchInput.focus() //搜索框默认获取焦点 this.setHideLoading() }, methods: { setHideLoading() { setTimeout(() => { this.pageLoading = false }, 500) }, onFocus(e) { this.focused = e.isFocused; this.$emit("onButtonFocused", e.isFocused); }, //输入内容之后请求城市 endEditing(e) { console.log("--resultData--", this.citySearchResult) }, onBackPressed() { ESLaunchManager.finishESPage(); }, resetModel() { this.citySearchResult = ""; this.hotCity = []; this.pageLoading = false; this.searchTitle = ""; this.searchDefaultKeyWord = ""; this.searchDefault = ""; }, } }</script>{{ searchTitle }}{{searchDefaultKeyWord}}<span>{{item.cityName}}</span>没有搜索结果~
