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"> <div class="index-root-search-title-css"> <span class="index-root-search-title-text-view-css"> {{ searchTitle }}</span> </div> <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> <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> <div class="search-city-empty" v-if="hotCity.length === 0"> <img src="@/assets/no_content.png" alt="" class="icon-no-connect"/> <p class="empty-txt">没有搜索结果~</p> </div> </div> </div> <loading-view style="width: 100px;height: 100px;position: absolute;left:960px;right:960px;top:500px;bottom:500px;align-self: center;align-items: center;justify-content: center" v-show="pageLoading"/> </div> </template> <script> import searchImage from "@/assets/search_focus.png";
