wxml中的绑定

 <textarea placeholder="文本类型"   bindblur='no_focus' bindfocus="focus" data-name= "c"></textarea>
 <input placeholder="input类型"  bindblur='no_focus' bindfocus="focus" data-name= "p"></input>
其他类型可以通过赋值的形式进行赋值传递 this.data.formData;

绑定事件

focus(e) {
      let name = e.currentTarget.dataset.name
      let value = e.detail.value;
      this.setData({
        ["formData." + name ]: value
      })
    },

    no_focus(e) {
      let name = e.currentTarget.dataset.name
      let value = e.detail.value;
      this.setData({
        ["formData." + name ]: value
      })
    },
