這篇文章主要介紹了微信小程序搜索框樣式并實(shí)現(xiàn)跳轉(zhuǎn)到搜索頁面(小程序搜索功能),需要的朋友可以參考下

一:搜索框功能實(shí)現(xiàn)

1.在首頁做一個(gè)搜索框的樣式并實(shí)現(xiàn)跳轉(zhuǎn)到搜索頁面

 <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="請輸入關(guān)鍵字" 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.點(diǎn)擊跳轉(zhuǎn)到搜索的頁面

 suo: function (e) {
 wx.navigateTo({
  url: '../search/search',
 })
 },

2.搜索頁面實(shí)現(xiàn)搜索功能

<!--pages/search/search.wxml-->
<view class="search page_row">
 <input class="df_1" placeholder="請輸入你有搜索的內(nèi)容" value="{{searchValue}}" bindinput="searchValueInput" />
 <button bindtap="suo" data-id='1'>
 媒婆
 </button>
 <button bindtap="suo" data-id='2'>
 單身
 </button>
</view>
<view class="search_no" wx:if="{{!centent_Show}}">
 <text>很抱歉,沒有找到您要搜索的資料/(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',//這里填寫后臺給你的搜索接口
  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: '網(wǎng)絡(luò)異常！',
   duration: 2000
  });
  },
 });
 }
});

/* pages/search/search.wxss */
@import "../index/card/card";
.searchcion{
 width: 24px;
 height: 24px;
 text-align: center;
 margin-top: 5rpx
}
.search{
 padding: 1% 3%;
 background: #D0D0D0;
}
.search input{
 width: 85%;
 border-radius: 5px;
 background: #fff;
 border: none;
 font-size: 12px;
 padding:1% 2.5%;
 margin-right: 5px;
 }
.search button{
 line-height:30px;
 text-align: center;
 border: none;
 font-size: 28rpx;
 background: white
}

php實(shí)現(xiàn)代碼

<?php
 header("Content-Type:text/html;charset=utf8"); 
 header("Access-Control-Allow-Origin: *"); //解決跨域
 header('Access-Control-Allow-Methods:POST');// 響應(yīng)類型 
 header('Access-Control-Allow-Headers:*'); // 響應(yīng)頭設(shè)置 
 $link=mysql_connect("localhost","root","root"); 
 mysql_select_db("shige", $link); //選擇數(shù)據(jù)庫
 mysql_query("SET NAMES utf8");//解決中文亂碼問題
 $str = $_POST['str'];
 
 //SQL查詢語句 SELECT * FROM 表名 LIKE 模糊搜索的變量
 $q="SELECT * FROM curriculum WHERE CONCAT_WS('',school,college,major,mtype,title) LIKE '%{$str}%'";
 
 $rs = mysql_query($q); //獲取數(shù)據(jù)集
 if(!$rs){die("數(shù)據(jù)庫沒有數(shù)據(jù)!");}
 
 //循環(huán)讀取數(shù)據(jù)并存入數(shù)組對象
 $dlogs;$i=0;
 while($row=mysql_fetch_array($rs))
 {
  $dlog['title']= $row["title"];
  $dlog['mtype']= $row["mtype"];
 $dlog['name']= $row["name"];
 $dlog['mfile']= $row["mfile"];
 $dlog['myear']= $row["myear"];
 $dlog['school']= $row["school"];
 $dlog['college']= $row["college"];
 $dlog['major']= $row["major"];
 $dlog['time']= $row["time"];
  $dlogs[$i++]=$dlog;
 }
 //以json格式返回html頁面
 echo urldecode(json_encode($dlogs));
?>
