Get rid of the span tags and enclose the content within a parent <td> tag

Question

Get rid of the span tags and enclose the content within a parent <td> tag

i have this example:

<td "class=name">
    <span class="removed">one</span>
    <span class="added">two</span>
</td>

or maybe this:

<td class=name> one
    <span class="removed">two</span>
    <span class="added">three</span>
</td>

or even this:

<div>
    one
    <span class="added">two</span>
    three four 
    <span class="removed">five</span>
    six
</div>

and I aim to transform it with JavaScript (no JQuery) into this:

<td "class=name">
    two
</td>

or possibly something like this:

<td class=name> 
    one
    three
</td>

or perhaps this:

<div>
    one
    two
    three
    four
    six
</div>

I am struggling to find a solution. I've only come across many jquery solutions like replaceWith, but I require plain javascript for this task.

Answer №1

If you're looking for the most efficient way to remove unnecessary elements with just one line of code using jQuery, look no further:

$('.added').contents().unwrap();

Here's what each part of this code does:

$('.added') = Finds and selects the element that has the class added.
.contents() = Retrieves the text content inside the selected element.
.unwrap() = Removes unnecessary wrapping tags like <span> and </span>, leaving just the content intact in its original position.

If you have a bunch of span tags with classes "removed" or "added" that you want to remove, and you don't want it to affect the rest of your HTML, you can give this code a try:

var spans = document.getElementsByTagName("span");

for(var i=0; i<spans.length;i++)
{
  if(spans[i].className == "added")
  {
     var container = spans[i].parentNode;
     var text = spans[i].innerHTML;
     container.innerHTML += text;
     container.removeChild(spans[i]);
  }
  else if(spans[i].className == "removed")
  {
      var container = spans[i].parentNode;
      container.removeChild(spans[i]);
  }
}

If not, you may need to identify the containers of the span tags by ID or class name, and perform something similar. Here's an example:

var myDiv = document.getElementById("myDiv");
var spans = myDiv.getElementsByTagName("span");   

for(var i=0; i<spans.length;i++)
{
  if(spans[i].className == "added")
  {
     var text = spans[i].innerHTML;
  }
  myDiv.innerHTML += text;
  myDiv.removeChild(spans[i]);
}

I hope this explanation is helpful!

UPDATE

You might find using a getElementsByClassName() function useful for simplifying this task. This function returns an array similar to getElementsByTagName(), allowing for easier iteration.

If you need to strip HTML classes from elements, consider implementing the following JavaScript function:

<div id="targetElement">Apple<span class="added">Banana</span>Cherry Pear<span class="removed">Grape</span>Kiwi</div>

<script type="text/javascript">
function removeHtmlClass(classname, targetElement){
        var content = document.getElementById(targetElement).innerHTML;
        var start = content.indexOf("<" + classname);
        while (start > -1) {
            end = content.indexOf(">", start);
            if (end > -1) {content = content.substr(0, start) + content.substr(end + 1, content.length);}
            end = content.indexOf("</" + classname + ">", start);
            if (end > -1){content = content.substr(0, end) + content.substr(end + 3 + classname.length, content.length);}
            start = content.indexOf("<" + classname, start);
        }document.getElementById(targetElement).innerHTML = content;}
</script>

<a href="javascript:removeHtmlClass('span', 'targetElement')">Remove span class</a>

</script>
