Vue利用flex布局实现TV端城市列表

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：

  
  
  {{searchDefaultKeyWord}}

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：

  

    

      
      
    
    {{item.cityName}}
  

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"

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,}

{{item.cityName}}

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()
},
