一:搜索框功能实现
1.在首页做一个搜索框的样式并实现跳转到搜索页面
<view class='page_row' bindtap="suo">
<view class="search">
<view class="df search_arr">
<icon class="searchcion" size='20' type='search'></icon>
<input class="" disabled placeholder="请输入关键字" value="{{searchValue}}"/>
</view>
</view>
<view class='sousuo'>搜索</view>
</view>

.search{
width: 80%;
}
.search_arr {
border: 1px solid #d0d0d0;
border-radius: 10rpx;
margin-left: 20rpx;
}
.search_arr input{
margin-left: 60rpx;
height: 60rpx;
border-radius: 5px;
}
.bc_text {
line-height: 68rpx;
height: 68rpx;
margin-top: 34rpx;
}

.sousuo {
margin-left: 15rpx;
width: 15%;
line-height: 150%;
text-align: center;
border: 1px solid #d0d0d0;
border-radius: 10rpx;
}
.page_row{
display: flex;
flex-direction: row
}
.searchcion {
margin: 10rpx 10rpx 10rpx 10rpx;
position: absolute;
left:25rpx;
z-index: 2;
width: 20px;
height: 20px;
text-align: center;
}

js.点击跳转到搜索的页面

suo: function (e) {
wx.navigateTo({
url: '../search/search',
})
},
2.搜索页面实现搜索功能
<!--pages/search/search.wxml-->
<view class="search page_row">
<input class="df_1" placeholder="请输入你有搜索的内容" value="{{searchValue}}" bindinput="searchValueInput" />
<button bindtap="suo" data-id='1'>
媒婆
</button>
<button bindtap="suo" data-id='2'>
单身
</button>
</view>
<view class="search_no" wx:if="{{!centent_Show}}">
<text>很抱歉,没有找到您要搜索的资料/(ㄒoㄒ)/~~</text>
</view>
<import src="../index/card/card.wxml" />
<template is="nanshen_card" data="{{nanshen_card,img}}" />

var app = getApp();
var searchValue =''
// pages/search/search.js
Page({
data: {
centent_Show: true,
searchValue: '',
img: '',
nanshen_card:''
},
onLoad: function () {
},
searchValueInput: function (e) {
var value = e.detail.value;
this.setData({
searchValue: value,
});
if (!value && this.data.productData.length == 0) {
this.setData({
centent_Show: false,
});
}
},
suo:function(e){
var id= e.currentTarget.dataset.id
var program_id = app.program_id;
var that = this;
wx.request({
url: 'aaa.php',//这里填写后台给你的搜索接口
method: 'post',
data: { str: that.data.searchValue, program_id: program_id, style:id },
header: {
'content-type': 'application/x-www-form-urlencoded'
},
success: function (res) {
if(res.data.length ==0){
that.setData({
centent_Show: false,
});
}
that.setData({
nanshen_card: res.data,
});
},
fail: function (e) {
wx.showToast({
title: '网络异常！',
duration: 2000
});
},
});
}
});
