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开发者_开发百科 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()
?
Change your function like this:
function delete_row(e)
{
e.parentNode.parentNode.parentNode.removeChild(e.parentNode.parentNode);
}
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
node.parentNode.parentNode.removeChild(node.parentNode)
Edit: You need to to delete parent of parent, so add one more .parentNode
node.parentNode.parentNode.parentNode.removeChild(node.parentNode.parentNode)
Or for those who like a one-liner
<button onClick="this.parentNode.parentNode.removeChild(this.parentNode);">Delete me</button>
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);
}

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:
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
}
}
<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>
Simple function to do this with ES6:
const removeImgWrap = () => {
const wrappedImgs = [...document.querySelectorAll('p img')];
wrappedImgs.forEach(w => w.parentElement.style.marginBottom = 0);
};
I know it's a little too late, but someone else might find it useful.
e.target.parentElement.parentElement.parentElement.remove()
<div>
<span>1<button onclick="removeParents(this);">X</button></span>
<span>2<button onclick="removeParents(this);">X</button></span>
<span>3<button onclick="removeParents(this);">X</button></span>
<span>4<button onclick="removeParents(this);">X</button></span>
</div>
<script>
function removeParents(e) {
var root = e.parentNode;
root.parentNode.removeChild(root);
console.log(root);
}
</script>
working sample
If you want to delete whatever is inside the <tr>
tags, by clicking on the "Delete", give that span a class name (whatever you want).
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 .whatever 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 because you can delete a DOM element just using CSS class and a bit of JS.
