how to set value in input by JavaScript?

Question

I have input field with id txt1 but I am unable to change the value from JavaScript.

<form action=""> 
First name: <input type="text" id="txt1" onkeyup="showHint(this.value)">
</form>

<script>
  document.getElementById('txt1').value('anyvalue1111');
</script>

Note: I find on stackoverflow how to change input value but could not found any answer. Title of the question save lot of time. It is valid question in this way.

value is a property and not a method.

document.getElementById('txt1').value = 'anyvalue1111';

Try this

<form action=""> 
    First name: <input type="text" id="txt1" onkeyup="showHint(this.value)">
    </form>

    <script>
    document.getElementById('txt1').value = 'Hello world!!';

    </script>

This syntax is for jQuery:

$('#txt1').val('anyvalue1111');

For Javascript use:

document.getElementById('txt1').value = 'anyvalue1111';
