微信小程序之间的参数传递、获取

一、获取当前页面参数

js

  onLoad: async function (options) {
    var pages = getCurrentPages() //获取加载的页面
    var currentPage = pages[pages.length - 1] //获取当前页面的对象
    var options = currentPage.options //如果要获取url中所带的参数可以查看options
    this.setData({
      contactid: options.contactid//这里的options.表示获取参数，contactid表示参数名称
    })
  },

当前页面参数可以在小程序开发工具的右下角查看

二、单独input文本框参数的获取

wxml：这里的bindconfirm指的是回车事件，也可以使用别的事件

<input class="input_comments" type="text" bindconfirm="comments" placeholder="请输入内容"/>

 js

  comments(e) {
    console.log("参数",e.detail.value) //这里面的值就是获取到文本框在中的值
  },

输出结果：在文本框输入：这是一个测试，回车，得到的结果如下

三、表单获取参数信息（包括多选，下拉列表，文本框，文本域）

案例

 wxml

<form action="" bindsubmit="addcontent_submit">
  <view class="pop1" bindtap="customerselect">
    <view class="pop1_title">
      <text style="color:red;">*</text>

    <view class="customered bright789_view_hide{{showView?'bright789_view_show':''}}">
      <view class="customered1">
        <view class="customered_title">客户名称</view>
        <view class="customered_content" >{{valid.customer_name}}</view>
      </view>
    </view>
  </view>

    <view class="pop4_title">
      <text>职位</text>
    </view>
    <view class="pop4_checkbox">
      <checkbox-group bindchange="handleItemChange">
        <checkbox value="{{item.jobname}}" wx:for="{{list}}" wx:key="id">
          {{item.jobname}}
        </checkbox>
      </checkbox-group>
      <view>选中职位：{{checkedList}}</view>
    </view>
  </view>

  <view class="pop5" bindtap="policymaker">
    <view class="pop5_title">
      <text>是否为关键决策人</text>

      <view class="pop5_input" style="float:left" name="policymaker">
        {{seleNull6?selectDatas6[index6]:'请选择'}}
      </view>
      <view style="font-size:18px;color:#808080;float:right;width:20px;">></view>
    </picker>
  </view>

  <view class="pop6">
    <view class="pop6_title">
      <text>邮箱</text>
    </view>
    <input class="pop6_input" name="contactemail" placeholder="请输入邮箱" />
  </view>

  <view class="pop7">
    <view class="pop7_title">
      <text>备注</text>
    </view>
    <textarea bindblur="bindTextAreaBlur1" class="pop7_input" name="contactremarks" placeholder="请输入"></textarea>
  </view>

  <view class="pop8">
    <view style="padding-top:2%;"> <button style="background-color:#70bdac;width:90%;" form-type="submit">提交</button></view>
  </view>
</form>

      // console.log("为空");
      this.setData({

      // 不加这个方法真机下拉会一直处于刷新状态，无法复位
      wx.stopPullDownRefresh()
    }, 3000)
  },
})

thinkphp(后端)

  //新增联系人
  public function addcontact()
  {
    $time = time(); //获取当前时间戳
    $customer_code = input('post.customer_code'); //客户代号
    $contactname = input('post.contactname'); //姓名
    $contactphone = input('post.contactphone'); //电话
    $checkedList = input('post.checkedList'); //职位
    $policymaker = input('post.policymaker'); //决策人
    $contactemail = input('post.contactemail'); //邮箱
    $contactremarks = input('post.contactremarks'); //备注
    $username = input('post.username'); //负责人
    $business_code = DB::table('fa_crm_user')->where(['username' => $username])->value('business_code');
    $data = [
      'customer_code' => $customer_code,
      'contacts_name' => $contactname,
      'contacts_phone' => $contactphone,
      'contacts_position' => $checkedList,
      'key_decision_makers' => $policymaker,
      'contacts_email' => $contactemail,
      'contacts_remark' => $contactremarks,
      'customer_principal' => $business_code,
      'creation_date' => $time,
      'enable_flag' => 'Y'
    ];
    db::table('customer_contact_xcx')->insert($data);//新增
    //获取联系人数据库中的id
    $maxid = DB::table('customer_contact_xcx')->max('id');
    //向客户动态添加数据
    $data2 = [
      'customer_code' => $customer_code,
      'operation' => '新增联系人',
      'details_id' => $maxid,
      'creation_date' => $time,
      'customer_principal' => $business_code,
    ];
    db::table('schedule_flow')->insert($data2);
  }
//查询所有职务
  public function customejob_select()
  {
    $customer_job = DB::table('customer_job')->select();
    echo json_encode($customer_job);
  }

四、点击表格单元格信息，获取改行id

样式：点击报价单号，跳转到详情页

wxml:

<view style="padding:15px;">
        <view class="table">
          <view class="table-tr">
            <view class="table-th1">报价单号</view>
            <view class="table-th2">客户简称</view>
            <view class="table-th3">客户名称</view>
            <view class="table-th4">金额</view>
            <view class="table-th4">需求日期</view>
            <view class="table-th4">报价日期</view>
            <view class="table-th4">交货日期</view>
          </view>
          <view class="table-tr" wx:for="{{pricelist_item}}" wx:key="unique">
            <view class="table-td1" bindtap="ppricelist_update" data-id="{{item.id}}">{{item.pricelist_num}}</view>
            <view class="table-td2">{{item.customer_code}}</view>
            <view class="table-td2">{{item.customer_name}}</view>
            <view class="table-td2">{{item.amount}}</view>
            <view class="table-td2">{{item.need_time}}</view>
            <view class="table-td2">{{item.offer_time}}</view>
            <view class="table-td2">{{item.delivery_time}}</view>
          </view>
        </view>
      </view>

在报价单的td中，设置方法bindtap="ppricelist_update"

设置需要传递的参数信息data-id="{{item.id}}"

js:执行方法跳转到另外一个页面

//点击报价单号进入详情页
  ppricelist_update(e){
    // console.log(e.currentTarget.dataset.id)//获取到报价单页面的参数
    wx.navigateTo({ //需要修改为wx.navigateTo
      //跳转到新增页面，不销毁原页面
      url: '/pages/price_list_update/price_list_update?pricelist_id=' + e.currentTarget.dataset.id,
    })
  },

e.currentTarget.dataset.id：为前端设置的data-id的数据

?后面的数据即为参数信息pricelist_id=' + e.currentTarget.dataset.id

在新页面获取数据

js:

 //进入页面
    onLoad: async function (options) {
      var pages = getCurrentPages() //获取加载的页面
      var currentPage = pages[pages.length - 1] //获取当前页面的对象
      var options = currentPage.options //如果要获取url中所带的参数可以查看options
      // console.log(options.pricelist_id);//控制台输出页面参数
    },

五、前端页面跳转，传递多个参数

follow_up(e) {
  wx.navigateTo({//跳转到新增页面，不销毁原页面
     url: '/pages/new_followrecord/new_followrecord?customer_code=' + e.currentTarget.dataset.id + "&issent=" + 1 + "&nowDate=" + this.data.nowDate,
    })
},

如上图：有参数customer_code，issent，nowDate

？后面加参数，参数与参数之间&连接文章来源地址https://www.toymoban.com/news/detail-484230.html
