小程序:动态监测input和取值

1.输入框失去焦点取值

  wxml:

    <input bindblur="tab" type='text'></input>

  js:

  tab:function(e){

    console.log(e)

  }

2.动态监测input输入的值

  wxml:

    <input type='number' bindinput='change' placeholder="请输入" placeholder-class="placeholder" focus="true"></input>

    focus 进入这个搜索页面后自动获取焦点

  js:

  change: function(r) {

    console.log(r.detail.value)

    this.setData({

      key: r.detail.value

    })

  },
