javascript - react native : Passing 2 parameter to onPress event

Question

我需要将两个参数传递给我的处理函数，但我找不到正确的语法，有人可以帮助我吗？

MyHandler = (e) => {
  var Var_1 = e;
  var Var_2 = second_parameter;
}

render() {
  return (
     <Button onPress={(e) => this.MyHandler(e)} title="1">
  );
}

Answer 1

你可以这样做:

MyHandler = (e, second_parameter) => {
  var Var_1 = e;
  var Var_2 = second_parameter;
}

render() {
  return (
     <Button onPress={(e) => this.MyHandler(e, your_second_parameter)} title="1">
  );
}
