Formatting input while values are typed-CodePudding

I'm trying to format the values typed by the user in realtime, I'm doing this for some data types but the only one that I cannot make it work is with currency (number). Based on my other data types I'm trying to solve it with the following code:

<input type="number" onkeypress="return parseFloat(this.value).toFixed(2).toLocaleString() " />

<input type="number" onkeypress="something(this.value);" />

function something(val) {
    return parseFloat(val).toFixed(2).toLocaleString();
}

function something(val) {
  return parseFloat(val).toFixed(2).toLocaleString();
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>



<input type="number" onkeypress="return parseFloat(this.value).toFixed(2).toLocaleString() " />

<input type="number" onkeypress="something(this.value);" />

What I'm trying to is that for example: if my user is trying to type 25999.84125 change the input value to 25999.84 but, any of my code examples are working.

How can I solve this? I'll prefer to keep the event function inside the input tag (example 1) but if the solution is writing a custom function it's okay. Also I'm open to use Regex.

For using changing the value real-time, don't return the data in the function, just set the value to the input ! Also you cannot do it exactly real-time with JS, you need to use onChange function like this:

function something(val, input) {
    document.getElementById(`input${input}`).value = parseFloat(val).toFixed(2).toLocaleString();
}

<input id="input1" type="number" onChange="something(this.value, 1);" />

<input id="input2" type="number" onChange="something(this.value, 2);" />

finally, if you want to do it exactly real time, use Vue js

I cannot vote as I am new here but the "Raymond Shafiee" answer is correct and acceptable otherwise if you jump into Vue (which i definitely suggest you) you can simply bind values to key and watch it for changes and change it as per required
