如何使用纯 Javascript 删除父元素

Question

How do I remove the parent element and all the respective nodes using plain JavaScript? I'm not using jQuery or any other library. In other words, I have an element and when user clicks on it, I want to remove the parent of the parent element (as well as the respective children nodes).

<table id='table'>
    <tr id='id'>
        <td>
            Mohit
        </td>   
        <td>
            23
        </td>   
        <td >
        <span onClick="edit(this)">Edit</span>/<span onClick="delete_row(this)">Delete</span>
        </td>   
        <td style="display:none;">
            <span onClick="save(this)">Save</span>
        </td>   
    </tr>   
</table>    

Now,

function delete_row(e)
{
    e.parentNode.parentNode.removeChild(e.parentNode);
}

Will remove only last <td> .

How do I remove the <tr> directly>?

e.parentNode.parentNode.getAttribute('id')

returns the id of the row...

Is there any function like remove() or delete() ?

Answer 1

Change your function like this:

function delete_row(e)
{
    e.parentNode.parentNode.parentNode.removeChild(e.parentNode.parentNode);
}

Answer 2

You can now use node.remove() to remove the whole element so in your case you'd do

function delete_row(e) {
    e.parentElement.remove();
}

You can read more on it here https://developer.mozilla.org/en-US/docs/Web/API/ChildNode/remove

Answer 3

node.parentNode.parentNode.removeChild(node.parentNode)

编辑：您需要删除父级的父级，因此再添加一个 .parentNode

node.parentNode.parentNode.parentNode.removeChild(node.parentNode.parentNode)

Answer 4

或者对于喜欢单线的人

<button onClick="this.parentNode.parentNode.removeChild(this.parentNode);">Delete me</button>

Answer 5

I know it's a little too late, but someone else might find it useful.
Just wrote a function for that.

Change this:

onClick="delete_row(this)"

To this:

onClick="removeParents(this, document.getElementById('id'))"

---

function removeParents(e, root) {
    root = root ? root : document.body;
    var p = e.parentNode;
    while(root != p){
        e = p;
        p = e.parentNode;
    }
    root.removeChild(e);
}

Simple function to do this with ES6:

const removeImgWrap = () => {
    const wrappedImgs = [...document.querySelectorAll('p img')];
    wrappedImgs.forEach(w => w.parentElement.style.marginBottom = 0);
};

Answer 7

我知道这有点太晚了，但其他人可能会发现它很有用。

 e.target.parentElement.parentElement.parentElement.remove()

Answer 8

I know I am too late but I still can't see more accurate answer.

So here you go.

You can specify it even more. Instead of parentElement.parentElement you can do something like this.

static delete_row(element) { 
   element.closest("tr").remove();
}

The other preferred way of handling such scenario would be event propagation instead of adding onclick to html element.

eg

HTML

<tr id='id'>
   <td>Mohit</td>   
   <td>23</td>
   <td > 
      <span class="edit">Edit</span> | 
      <span class="delete">Delete</span>
   </td>   
   <td style="display:none;"><span class="save">Save</span></td>   
</tr>

JavaScript

 document.querySelector("#id").addEventListener("click", (e) => {
   UI.handleEvents(e.target);
 });

 static handleEvents(el){

   if (el.classList.contains("delete")) {
     el.closest("tr").remove();
   }

   if (el.classList.contains("edit")) {
     // do something else
   }
   
   if (el.classList.contains("save")){
     // save records
   }

 }

Answer 9

Great question. This worked for me:

 e.target.parentElement.parentElement.parentElement.remove()

Answer 10

If you want to delete wtvr is inside the 'tr' '/tr' tags, by clicking on the "Delete", give that span a class name, (wtvr you wan't :D) And then in JS code: you basically select the element people will click with the document.querySelector(), add an Event Listener to it & on clicking on that span with that .wtvr class, the element with the ID name "id" will be removed.

 document.querySelector('.wtvr').addEventListener('click', function () { document.getElementById('id').remove(); });

 <table id="table"> <tr id="id"> <td>Mohit</td> <td>23</td> <td><span>Edit</span>/<span class="wtvr">Delete</span></td> <td style="display: none"> <span>Save</span> </td> </tr> </table>

I took the onclick away, dunno what you need them for. Cause you can delete a DOM element just using CSS class and a bit of JS. Hope this helps others if this is not your case. I was specific in explaining so newbies, like me, can understand the logic better.
