1.生命周期函数--监听页面加载(options接收值)

1.1 navigator

1. <!--pages/auction/auction.wxml-->
<view class="container">

  <view class="auction-item" wx:for="{{auctionList}}" wx:for-item="row" wx:key="index">
  <navigator url="/pages/auctionDetail/auctionDetail?auctionId={{row.id}}">


2. // pages/auctionDetail/auctionDetail.js
onLoad: function(options) {
this.setData({
  auctionId: options.auctionId
});

1.2 navigateTo

1. // pages/auctionDetail/auctionDetail.js

wx.navigateTo({
    url: \'/pages/deposit/deposit?itemId=\' + itemId
  })


2. // pages/deposit/deposit.js

onLoad: function(options) {
this.setData({
  itemId: options.itemId
});

2. 绑定点击事件传值

1. <!--pages/auctionDetail/auctionDetail.wxml-->

<block wx:if="{{auctionDetail.deposit.total}}">
  <view class="bottom" bindtap="toBid" data-itemid="{{item.id}}">
    <label>竞 拍</label>
  </view>
</block>

2. // pages/auctionDetail/auctionDetail.js

toBid: function(e) {
  var itemId = e.currentTarget.dataset.itemid;
  if (auth.authentication) {
    wx.navigateTo({
      url: \'/pages/bid/bid?itemId=\' + itemId
  })
    }
  }

3. 双向绑定实时改变值

1. <!--pages/login/login.wxml-->

<view class="form">
<view class="row-group">
    <text>手机</text>
    <input placeholder="请填写手机号码" placeholder-class=\'txt\' maxlength=\'11\' bindinput="bindPhoneInput" value="{{phone}}" />
</view>
<view class="row-group">
    <text>验证码</text>
    <input placeholder="请填写验证码" placeholder-class=\'txt\' maxlength=\'4\' bindinput="bindCodeInput" value="{{code}}" />
    <view class="code" bindtap="onClickCheckCode">获取验证码</view>
</view>
<view>
    <button class="submit" open-type="getUserInfo" bindgetuserinfo="onClickSubmit">登录 | 注册</button>
</view>
</view>



2. // pages/login/login.js

data: {
phone: "15131255089",
code: ""
},

bindPhoneInput: function(e) {
this.setData({
  phone: e.detail.value
});
},
bindCodeInput: function(e) {
this.setData({
  code: e.detail.value
});
}
