Steps for setting all textareas on a website to "readonly" mode

My website contains numerous textareas but they currently do not have the read-only attribute. It would be very time-consuming to manually add the readonly attribute to each one. Is there a more efficient method to make all textareas read-only?

Answer №1

One way to control the accessibility of textareas on a webpage is by using JavaScript to select all the textareas and then looping through them to set the readonly attribute to true.

/** ES6 VERSION **/
{
  let textareas=document.getElementsByTagName("textarea"),
      x=textareas.length;
  while(x--)
    textareas[x].readOnly=1;
}
/** ES5 VERSION
(function(){
  var textareas=document.getElementsByTagName("textarea"),
      x=textareas.length;
  while(x--)
    textareas[x].readOnly=1;
})();
**/

<textarea></textarea>
<textarea></textarea>
<textarea></textarea>

* It's important to note that this method may not be foolproof, as it can be easily bypassed by disabling JavaScript in the browser. A more secure approach would be manually setting the readonly attribute for each textarea in the code. However, even this could potentially be overridden by someone with knowledge of their browser's developer tools.

If you're working with VanillaJS, this snippet of code will do the trick:

const textAreas = document.getElementsByTagName("textarea");

for (let i = 0; i < textAreas.length; i++) {
    textAreas[i].readOnly = true;
}

But if you prefer using jQuery:

$('textarea').attr('readonly', true);

If you want to disable all your textareas, one approach is to wrap them in a fieldset and then disable the fieldset itself:

var myFieldset = document.getElementById("fieldset");
disableAll.onclick = function () { myFieldset.disabled = true; }
enableAll.onclick = function () { myFieldset.disabled = false; }

<button id="disableAll">Disable all</button>
<button id="enableAll">Enable all</button>

<form>
    <fieldset id="fieldset">
        <div>
            <input type="text" value="example text"/>
        </div>
        <div><textarea>your content</textarea></div>
        <div><input type="button" value="a button"/></div>
    </fieldset>
</form>

An alternative method using jQuery would be:

$('input[type=text], textarea').attr('readonly', true);
