最近在做一个小程序的页面，搜索框困扰了我很久，今天终于把搜索框给做了出来，记录一下过程
我主要使用的就是wx的if，当我输入框用户点击的时候，我前面的显示界面添加上false属性，然后我搜索页面显示出true的属性，至于模糊搜索，我是直接使用的js的匹配，话不多说，直接看成果和代码
代码
wxml
<view style="display: flex; align-items: center;background-color: rgb(71, 189, 254); margin-top: 200rpx;">
<input placeholder="请输入关键词" focus="{{inputFocus}}" bindfocus="onFocus" bindblur="onBlur" style="border: 1px solid #ccc; padding: 10rpx; border-radius: 10rpx; flex: 1;background-color: rgb(255, 255, 255);" />
<button wx:if="{{showSearch}}"
bindtap="quxiao"
style="margin-left: 10rpx; padding: 5rpx 10rpx; color: #fff; border-radius: 5rpx; width: 140rpx;background-color: rgb(71, 189, 254);"
