微信小程序实现不同按钮跳转同一个页面显示不同内容

<view >
<view wx:for="{{proList}}" wx:key="{{index}}">
<navigator url="/pages/anniu/anniu?goodsId={{index}}">
<button class="anniuer" type="primary">{{item}}</button>
</navigator>
</view>
</view>

Page({
data: {
proList:[
'按钮一',
'按钮二'
]
},
})

<view>
<view>标题:{{showTitle}}</view>
<view>内容:{{showContent}}</view>
</view>

Page({
  data: {
   showTitle:'', /**定义内容 */
   showContent:'',
   showProList:[
     {title:'我是标题一',content:'我是内容一'},
     {title:'我是标题二',content:'我是内容二'},
   ]
  },
  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {
    var goodsId = options.goodsId
    //  console.log(goodsId);
    this.setData({
      showTitle:this.data.showProList[goodsId].title, 
      showContent:this.data.showProList[goodsId].content,
    })
  }, 
})
