Object doesn't support property or method 'remove'

I know there is some issue with get document.getElementById and IE, but not sure why IE is having a problem with .remove and all other browsers are not. Any help here would be appreciated. I am getting the error

SCRIPT438: Object doesn't support property or method 'remove'

from the error console. The Javascript works in all other browsers. Here is the code:

<script type="text/javascript"><!--
function removeModule() {

    <?php $tab = 1; ?>
    var module_row = <?php echo $module_row; ?>;

    if(!confirm('Are you sure?'))
    {
        return false;
    }

        var x = 1;
        while (x < module_row)
        {
            if (document.getElementById('tab-' + x).checked)
            {           
                document.getElementById('tab-' + x).remove();
                document.getElementById('module-' + x).remove();
                document.getElementById('tab-module-' + x).remove();
            }
            x++;
            <?php $tab++; ?>
        }
        $('#form').submit();

}
//--></script>

This is from an opencart module, it is the tpl file. I've included part of the file here as well so hopefully someone can spot whatever the error is.

remove() as a method on HTMLElements unfortunately is not supported by Internet Explorer.

You could use the workaround in this SO answer for a vanilla javascript solution.

However as you already seem to use jQuery, instead replace

document.getElementById('tab-' + x).remove();

with

$('#tab-' + x).remove();

You should get the parent of the element you are trying to remove and use the remove child method to find and remove the element

element.parentNode.removeChild(element);

this works in all browsers including IE.


You should use this

element.parentElement.removeChild(element);

Supported by all browser and also have some benefits over just a hack to remove child element.

Here is another workaround for keep using .remove() function

Element.prototype.remove = function() {
    this.parentElement.removeChild(this);
}
NodeList.prototype.remove = HTMLCollection.prototype.remove = function() {
    for(var i = this.length - 1; i >= 0; i--) {
        if(this[i] && this[i].parentElement) {
            this[i].parentElement.removeChild(this[i]);
        }
    }
}

And then you can remove elements like this

document.getElementById("my-element").remove();

or

document.getElementsByClassName("my-elements").remove();

Here is Stack Overflow link for further info also source of this answer.


It appears that IE10 also throws this error..

Here one way I tried using the objects outerHTML property:

    if(typeof document.getElementById('id').remove=='function'){
       //If support  is found 
        document.getElementById('id').remove()
    }
    else{
      //If not
       document.getElementById('id').outerHTML='';
   }
