I have a html-form with hidden input elements.

Within JS I use

document.getElementId("xxx").value = "test";

to update hidden form elements.

After updating, I can see the updated content.

alert(document.getElementId("xxx").value);

All good so far.

But when I look in the source code, the element value is NOT changed.

Is this possible at all? If so, how can I change the input-value so it is also reflected in the source code, but without reloading the website.

Thanks, BM

Source code in HTML does not change Only DOM elements is changed You can inspect elements to see the changes of DOM in console
