本章节为微信小程序weui开放的最后一个组件，searchbar搜索栏的实现，详情如下：
一、引入小程序weui css样式库，请参考第一章
二、在pages目录中新建目录searchbar以及文件searchbar.wxml，并添加如下代码
<view class="page">
<view class="page__hd">
<view class="page__title">SearchBar</view>
<view class="page__desc">搜索栏(www.vxzsk.com V型知识库原创)</view>
</view>
<view class="page__bd">
<view class="weui-search-bar">
<view class="weui-search-bar__form">
<view class="weui-search-bar__box">
<icon class="weui-icon-search_in-box" type="search" size="14"></icon>
<input type="text" class="weui-search-bar__input" placeholder="搜索" value="{{inputVal}}" focus="{{inputShowed}}" bindinput="inputTyping" />
<view class="weui-icon-clear" wx:if="{{inputVal.length > 0}}" bindtap="clearInput">
<icon type="clear" size="14"></icon>
</view>
</view>
<label class="weui-search-bar__label" hidden="{{inputShowed}}" bindtap="showInput">
<icon class="weui-icon-search" type="search" size="14"></icon>
<view class="weui-search-bar__text">搜索</view>
</label>
</view>
<view class="weui-search-bar__cancel-btn" hidden="{{!inputShowed}}" bindtap="hideInput">取消</view>
</view>
<view class="weui-cells searchbar-result" wx:if="{{inputVal.length > 0}}">
<navigator url="" class="weui-cell" hover-class="weui-cell_active">
<view class="weui-cell__bd">
<view>实时搜索文本</view>
</view>
</navigator>
<navigator url="" class="weui-cell" hover-class="weui-cell_active">
<view class="weui-cell__bd">
<view>实时搜索文本</view>
</view>
</navigator>
<navigator url="" class="weui-cell" hover-class="weui-cell_active">
<view class="weui-cell__bd">
<view>实时搜索文本</view>
</view>
</navigator>
<navigator url="" class="weui-cell" hover-class="weui-cell_active">
<view class="weui-cell__bd">
<view>实时搜索文本</view>
</view>
</navigator>
</view>
</view>
</view>三、在根目录app.json配置文件中配置searchbar文件路径，保存后会自动生成对应的js、css等文件
"pages/searchbar/searchbar",
四、searchbar.wxss代码实现
.searchbar-result{
margin-top: 0;
font-size: 14px;
}
.searchbar-result:before{
display: none;
}
.weui-cell{
padding: 12px 15px 12px 35px;
}五、searchbar.js代码实现
Page({
data: {
inputShowed: false,
inputVal: ""
},
showInput: function () {
this.setData({
inputShowed: true
});
},
hideInput: function () {
this.setData({
inputVal: "",
inputShowed: false
});
},
clearInput: function () {
this.setData({
inputVal: ""
});
},
inputTyping: function (e) {
this.setData({
inputVal: e.detail.value
});
}
});六、效果
如上图红色圈圈部分，点击搜索框，会出现实时搜索文本，类似于百度搜索一样，体验很好。
