Reset input value after alert - Javascript

Question

I have a simple input box where if the number is higher than 2, a popup message will appear.

Here is the code I am using, however I already have an onkeyup command on the input for something else, so I hope that won't be a problem

HTML:

<input id="jj_input23" type="text" value='' onkeyup='changeTransform()' />

Javascript:

if(jj_input23 > 2) {
    alert("Making the scale higher than 2 will make the preview too big");
    document.getElementById('jj_input23').value("");
}

After the aler message has been displayed, and the user has clicked "Ok", I want the input text to reset. How can I do this?

Thanks in advance

if(jj_input23 > 2) {
    alert("Making the scale higher than 2 will make the preview too big");
    document.getElementById('jj_input23').value = "";
}

If you're using jQuery then you almost got it:

$('#jj_input23').val("");

I have tried clearing by replacing the value with (""), however, the input field validation is not resetting back to default. Could you please let me know how to deal with that?

@Anand are you using the built-in HTML required validation or something custom?

.value is a property, not a function.

You want .value = "";.
