如何禁用可拖动按钮的 onclick 事件？

Question

I have a draggable div, inside it is a button, this button will popup a modal on clicked. But whenever i click on that div in order to drag it, it triggers the onclick event of the button as well. I want to disable that button if i were dragging, it should only be trigger when i simply click on it.

 dragElement(document.getElementById("fdivAdd")); function dragElement(elmnt) { var pos1 = 0, pos2 = 0, pos3 = 0, pos4 = 0; if (document.getElementById(elmnt.id + "header")) { /* if present, the header is where you move the DIV from:*/ document.getElementById(elmnt.id + "header").onmousedown = dragMouseDown; } else { /* otherwise, move the DIV from anywhere inside the DIV:*/ elmnt.onmousedown = dragMouseDown; } function dragMouseDown(e) { e = e || window.event; e.preventDefault(); // get the mouse cursor position at startup: pos3 = e.clientX; pos4 = e.clientY; document.onmouseup = closeDragElement; // call a function whenever the cursor moves: document.onmousemove = elementDrag; } function elementDrag(e) { e = e || window.event; e.preventDefault(); // calculate the new cursor position: pos1 = pos3 - e.clientX; pos2 = pos4 - e.clientY; pos3 = e.clientX; pos4 = e.clientY; // set the element's new position: elmnt.style.top = (elmnt.offsetTop - pos2) + "px"; elmnt.style.left = (elmnt.offsetLeft - pos1) + "px"; } function closeDragElement() { /* stop moving when mouse button is released:*/ document.onmouseup = null; document.onmousemove = null; } }

 #fdivAdd { width: 80px; height: 80px; position: fixed; right: 45px; bottom: 93px; cursor: pointer; z-index: 9; background-color: #007bff; border-radius: 40px; } #fbtnAdd { width: 80px; height: 80px; border-radius: 40px; /* margin: 0; position: absolute; top: 50%; left: 50%; -ms-transform: translateY(-50%) translateX(-50%); transform: translateY(-50%) translateX(-50%); */ font-size: 25px; color: white; }

 <div id="fdivAdd"> <p id="fbtnAdd" data-toggle="modal" data-target="#exampleModal" data-whatever="@getbootstrap">Add</p> </div>

Use a boolean and make life easy:

var moving = false;
if(moving == true) {
   disableBtn("Button Id");
} else {
  // Do what you did before
}

function disbaleBtn(btnId) {
  console.log(btnId);
  document.getElementById(btnId).onclick = "return false";
}

Set the bool to true in your dragging code, and false while not. Add the if statement to where the onclick is otherwise used
