이벤트가 사람에 의해 트리거되는지 확인

이벤트가 사람에 의해 트리거되는지 확인

---

이벤트에 처리기가 연결되어 있으며 trigger () 메서드가 아닌 사람이 트리거하는 경우에만 실행하고 싶습니다. 차이점을 어떻게 알 수 있습니까?

예를 들어

$('.checkbox').change(function(e){
  if (e.isHuman())
  {
    alert ('human');
  }
});

$('.checkbox').trigger('change'); //doesn't alert

---

당신은 확인할 수 있습니다 e.originalEvent: 그것이 정의 된 경우 클릭은 인간입니다 :

바이올린 http://jsfiddle.net/Uf8Wv/를보십시오

$('.checkbox').change(function(e){
  if (e.originalEvent !== undefined)
  {
    alert ('human');
  }
});

바이올린에서 내 예 :

<input type='checkbox' id='try' >try
<button id='click'>Click</button>

$("#try").click(function(event) {
    if (event.originalEvent === undefined) {
        alert('not human')
    } else {
        alert(' human');
    }


});

$('#click').click(function(event) {
    $("#try").click();
});

---

위보다 더 똑바로 :

$('.checkbox').change(function(e){
  if (e.isTrigger)
  {
    alert ('not a human');
  }
});

$('.checkbox').trigger('change'); //doesn't alert

---

이 작업을 수행하는 유일한 방법 trigger은 설명서 에 따라 호출시 추가 매개 변수를 전달하는 것 입니다.

$('.checkbox').change(function(e, isTriggered){
  if (!isTriggered)
  {
    alert ('human');
  }
});

$('.checkbox').trigger('change', [true]); //doesn't alert

수락 된 답변이 효과가 없었습니다. 6 년이 지났으며 jQuery는 그 이후로 많은 변화를 겪었습니다.

For example event.originalEvent returns always true with jQuery 1.9.x. I mean object always exists but content is different.

Those who use newer versions of jQuery can try this one. Works on Chrome, Edge, IE, Opera, FF

if ((event.originalEvent.isTrusted === true && event.originalEvent.isPrimary === undefined) || event.originalEvent.isPrimary === true) {
    //Hey hooman it is you
}

You can use onmousedown to detect mouse click vs trigger() call.

---

I would think about a possibility where you check the mouse position, like:

• Click
• Get mouse position
• Overlaps the coords of the button
• ...

Incase you have control of all your code, no alien calls $(input).focus() than setFocus().

Use a global variable is a correct way for me.

var globalIsHuman = true;

$('input').on('focus', function (){
    if(globalIsHuman){
        console.log('hello human, come and give me a hug');
    }else{
        console.log('alien, get away, i hate you..');
    }
    globalIsHuman = true;
});

// alien set focus
function setFocus(){
    globalIsHuman = false;
    $('input').focus();
}
// human use mouse, finger, foot... whatever to touch the input

If some alien still want to call $(input).focus() from another planet. Good luck or check other answers

Currently most of browsers support event.isTrusted:

if (e.isTrusted) {
  /* The event is trusted: event was generated by a user action */
} else {
  /* The event is not trusted */
}

From docs:

The isTrusted read-only property of the Event interface is a Boolean that is true when the event was generated by a user action, and false when the event was created or modified by a script or dispatched via EventTarget.dispatchEvent().
