如何使用js触发'contenteditable'元素进入编辑状态？

Question

我想使用“contenteditable”属性实现元素就地编辑。是否可以通过鼠标事件模拟而不是用户单击进入编辑状态？

function triggerEvent(element, eventType) {
    let rect = element.getBoundingClientRect();
  console.log(rect);

    let event = new MouseEvent(eventType, {
    clientX: rect.left + 20,
    clientY: rect.top + 10,
    view: window,
    buttons: 1,
    bubbles: true,
  });
  element.dispatchEvent(event);
}

document.getElementById('btn').addEventListener('click', (event) => {
    let editArea = document.getElementById('edit-area');
  editArea.setAttribute('contenteditable', true);

  triggerEvent(editArea, 'mousedown');
});

你只需要focusdiv：

let div = document.querySelector('div');

div.focus();

<div contenteditable="true">Div Content</div>
