Javascript Solutions

Solution 1 - Javascript

It's actually a simple answer.

Your function is returning a string rather than the div node. appendChild can only append a node.

For example, if you try to appendChild the string:

var z = '<p>test satu dua tiga</p>'; // is a string 
document.body.appendChild(z);

The above code will never work. What will work is:

var z = document.createElement('p'); // is a node
z.innerHTML = 'test satu dua tiga';
document.body.appendChild(z);

Solution 2 - Javascript

This can happen if you accidentally are not dragging the element that does have an id assigned (for example you are dragging the surrounding element). In that case the ID is empty and the function drag() is assigning an empty value which is then passed to drop() and fails there.

Try assigning the ids to all of your elements, including the tds, divs, or whatever is around your draggable element.

Solution 3 - Javascript

You may also use element.insertAdjacentHTML('beforeend', data);

Please read the "Security considerations" on MDN.

Solution 4 - Javascript

In my case, there was no string on which i was calling appendChild, the object i was passing on appendChild argument was wrong, it was an array and i had pass an element object, so i used divel.appendChild(childel[0]) instead of divel.appendChild(childel) and it worked. Hope it help someone.

Solution 5 - Javascript

use ondragstart(event) instead of ondrag(event)

Solution 6 - Javascript

For future readers who want to use React 17 new react/jsx-transform to just use jsx syntax without using any hook:

uninstall react via npm uninstall react
keep your react-dom
update babel config. Add:
```
plugins: [
  ['@babel/plugin-transform-react-jsx', { runtime: 'automatic' }],
]
```
note: you can replace @babel/preset-react with @babel/plugin-transform-react-jsx, as indicated in this code.

change your syntax to

ReactDOM.render(<Comp/>, document.getElementById('fuc_'))
