I'm looking to create a textarea that automatically types in all capital letters, regardless of the user's input or whether they are holding down the shift key. I want it to accept any input and convert it to uppercase on the fly without showing the lowercase version first. Most of my ideas for achieving this seem cumbersome and would display the lowercase characters before conversion.
Does anyone have suggestions or strategies to achieve this?
To change the text in a textarea to uppercase using CSS:
textarea { text-transform: uppercase; }
Keep in mind that this will only visually render as uppercase on the browser. If you need the text to be in all caps when injected into a script or database, you'll have to utilize JavaScript's toUpperCase(); method before insertion or form submission.
Here is an example of how to accomplish this with code:
HTML:
<textarea>I really like jAvaScript</textarea>
CSS:
textarea{
text-transform: uppercase;
}
JavaScript:
var myTextArea = document.getElementsByTagName('textarea');
for(var i=0; i<myTextArea.length; i++){
console.log('Textarea ' + i + ' output: ' + myTextArea[i].innerHTML); //I really like jAvaScript
console.log('Textarea ' + i + ' converted output: ' + myTextArea[i].innerHTML.toUpperCase()); //I REALLY LIKE JAVASCRIPT
}
CSS Styling:
textarea { text-transform: uppercase; }
Hello Quintin,
To improve the text appearance, consider adding this style to your CSS:
textarea{ text-transform:uppercase; }
Consider implementing the following CSS code:
textarea{
text-transform: uppercase;
}
This will transform the input in the text area to uppercase style.
Include and acquire it CSS:
textarea { text-transform: uppercase; }
To convert text to uppercase using the oninput attribute, you can implement it like this:
<textarea oninput="this.value = this.value.toUpperCase()">
<label for="upperCaseTextArea" style="display:block;">
Upper Case Text Area
</label>
<textarea
id="upperCaseTextArea"
name="upperCaseText"
rows="5"
cols="15"
oninput="this.value=this.value.toUpperCase()"
>
