How to use localize-content with JS?

[Sayed-Mahmoud]

an example:
var button = document.createElement('a'); button.appendChild(document.createTextNode('Delete')); button.setAttribute('onclick', 'removeRow(this)'); button.setAttribute('class', 'btn btn-danger'); td.appendChild(button);

[LazZiya]

Create a hidden HTML item with the localized text, then grab its value with js.

<i style="display:none;" id="txt" localize-content>Delete</i>

<script>
    var delText = document.getElementById("txt").innerText;
    var button = document.createElement('a'); 
    button.appendChild(document.createTextNode(delText));
    ...
</script>
