What is innerHTML on input elements?
Solution 1
Setting the value
is normally used for input/form elements. innerHTML
is normally used for div, span, td and similar elements.
value
applies only to objects that have the value attribute (normally, form controls).
innerHtml
applies to every object that can contain HTML
(divs, spans, but many other and also form controls).
They are not equivalent or replaceable. Depends on what you are trying to achieve
Solution 2
First understand where to use what.
<input type="text" value="23" id="age">
Here now
var ageElem=document.getElementById('age');
So on this ageElem
you can have that many things what that element contains.So you can use its value
,type
etc attributes. But cannot use innerHTML because we don't write anything between input tag
<button id='ageButton'>Display Age</button>
So here Display Age
is the innerHTML content as it is written inside HTML tag button.
Solution 3
Using innerHTML on an input tag would just result in:
<input name="button" value="Click" ... > InnerHTML Goes Here </input>
But because an input tag doesn't need a closing tag it'll get reset to:
<input name="button" value="Click" ... />
So it's likely your browsers is applying the changes and immediatly resetting it.
Solution 4
do you mean something like this:
$('.activeElement').val('Some text');
Solution 5
<input id="input" type="number">
document.getElementById("input").addEventListener("change", GetData);
function GetData () {
var data = document.getElementById("input").value;
console.log(data);
function ModifyData () {
document.getElementById("input").value = data + "69";
};
ModifyData();
};
My comments: Here input field works as an input and as a display by changing .value

I'm just trying to do this from the chrome console on Wikipedia. I'm placing my cursor in the search bar and then trying to do
document.activeElement.innerHTML += "some text"
but it doesn't work. I googled around and looked at the other properties and attributes and couldn't figure out what I was doing wrong.The
activeElement
selector works fine, it is selecting the correct element.Edit: I just found that it's the
value
property. So I'd like to change what I'm asking. Why doesn't changinginnerHTML
work on input elements? Why do they have that property if I can't do anything with it? -
