I'm in need of assistance with updating HTML code similar to the following:
<textarea name="message"></textarea>
Specifically, I want to make a modification so that it appears as follows:
<textarea maxlength="300" name="message"></textarea>
I'm searching for a way to achieve this using JavaScript. Despite attempting various solutions sourced from different places, none have proven successful thus far. If necessary, I am also open to utilizing CSS code.
If you're not utilizing jQuery (which is highly advised), this is the approach:
let element = document.getElementsByName('input-field')[0];
element.setAttribute('maxLength', 250);
Check out the jsFiddle example
Identify the tag element with jQuery and apply the .attr() method.
If you prefer not to use jQuery:
<textarea id="input" name="content"></textarea>
var textArea = document.getElementById("input");
textArea.setAttribute("maxlength","500");
Using the document.querySelector method to target the 'message' input and setting its maximum character length to 300.
$('textarea').setAttribute('maxlength', 300);
