react常用技巧

<Input placeholder="请输入用户名"
                  value={this.state.form.username}
                  onChange={(e) => this.handdleChange(e, "username")}
                  allowClear={true}
                />
  handdleChange = (e, name) =>{  ==>es写法可以获取this对象的值
    console.log(name);
   // this.state.form[name] = e.target.value;
    let data = this.state.form;
    data[name] = e.target.value;
    this.setState({
      form:data
    })
  }

如 this.state = {
  type:'',
  form:{
     name:'',
           age:''
        }
  }
  handdleChange = (e, name) =>{  ==>es写法可以获取this对象的值
    console.log(name);
    let data = this.state.form;
    data[name] = e.target.value;
    this.setState({
      form:data
    })
  }
