Techniques for ensuring input validity using JavaScript

One of my form inputs is required:

<input type="text" id="input-id" required>

After the user submits it, I send the value using ajax and then clear it with $("#input-id").val("").
However, after this action, the input appears invalid. I want to reset it to its original look as if the page just loaded. How can I achieve this using JavaScript? Is there a better way to clear the input?

Answer №1

Check out the instructions mentioned here:

document.getElementById(selector).reset();

To reset a specific field, you can use the defaultValue attribute:

function reset() {
  field = document.getElementById('field');
  field.value = field.defaultValue;
}
<input id="field" type="text" required>
<button onclick="reset()">reset field</button>

Alternatively, you can create a form inside another form that only contains the fields you wish to reset, and then reset the inner form.

Answer №2

$(document).ready(function () {
   $("#input-id").val("");
   //If you also want to set innerText:
   var ele = document.getElementById('input-id');
   ele.innerText= $("#input-id").val();
};

When the document finishes loading, the input field will be cleared. You can insert this code snippet wherever you see fit on your page.
