小程序頂部搜索框怎么實(shí)現(xiàn)
實(shí)現(xiàn)效果如下:
具體代碼:
1、WXML文件
<!--搜索框 --> <view class="weui-search-bar"> <view class="weui-search-bar__form"> <!--點(diǎn)擊之后,出現(xiàn)input框 --> <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" /> <!--輸入款字?jǐn)?shù)大于0,則顯示清除按鈕 --> <view class="weui-icon-clear" wx:if="{{inputVal.length > 0}}" bindtap="clearInput"> <icon type="clear" size="14"></icon> </view> </view> <!--沒(méi)點(diǎn)擊之前,只是一些文字和圖標(biāo) --> <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> <!--動(dòng)態(tài)出現(xiàn)的“取消”鍵 --> <view class="weui-search-bar__cancel-btn" hidden="{{!inputShowed}}" bindtap="hideInput">取消</view> </view>
2、WXSS文件
.weui-search-bar { position: relative; padding: 8px 10px; display: -webkit-box; display: -webkit-flex; display: flex; box-sizing: border-box; background-color: #EFEFF4; border-top: 1rpx solid #D7D6DC; border-bottom: 1rpx solid #D7D6DC; } .weui-icon-search { margin-right: 8px; font-size: inherit; } .weui-icon-search_in-box { position: absolute; left: 10px; top: 7px; } .weui-search-bar__text { display: inline-block; font-size: 14px; vertical-align: middle; } .weui-search-bar__form { position: relative; -webkit-box-flex: 1; -webkit-flex: auto; flex: auto; border-radius: 5px; background: #FFFFFF; border: 1rpx solid #E6E6EA; } .weui-search-bar__box { position: relative; padding-left: 30px; padding-right: 30px; width: 100%; box-sizing: border-box; z-index: 1; } .weui-search-bar__input { height: 28px; line-height: 28px; font-size: 14px; } .weui-icon-clear { position: absolute; top: 0; right: 0; padding: 7px 8px; font-size: 0; } .weui-search-bar__label { position: absolute; top: 0; right: 0; bottom: 0; left: 0; z-index: 2; border-radius: 3px; text-align: center; color: #9B9B9B; background: #FFFFFF; line-height: 28px; } .weui-search-bar__cancel-btn { margin-left: 10px; line-height: 28px; color: #09BB07; white-space: nowrap; font-size: 30rpx; }
3、JS文件
showInput: function () { this.setData({ inputShowed: true }); }, hideInput: function () { this.setData({ inputVal: "", inputShowed: false }); // getList(this); }, clearInput: function () { this.setData({ inputVal: "" }); // getList(this); }, inputTyping: function (e) { //搜索數(shù)據(jù) // getList(this, e.detail.value); this.setData({ inputVal: e.detail.value }); }
