Issue with uppercase letters within a text input field

Question

Issue with uppercase letters within a text input field

Imagine having an <input> and a <textarea> along with some JavaScript code that sends the value of the <input> to the <textarea> with additional text. How can you achieve this task?

The text-transform: capitalize property is set in the style of the <input> element. However, the text from the <input> does not get transferred to the <textarea> with proper capitalization. Applying text-transform: capitalize to the <textarea> makes all words capitalized, which is not desired. How can you work around this issue?

function sendText(){
  var input =document.getElementById("input");
  var textarea =document.getElementById("textarea");
  
  textarea.value ="My name is " + input.value;
  
}

input{
  margin-right:10px;
 float:left;
  text-transform: capitalize;
}
textarea{
  height:30px;
  width:140px;
  float:left;
  
}

<html>
<body>
  <input id="input" onkeyup="sendText()" placeholder="Your Name Here"><textarea id="textarea"></textarea>
</body>
</html>

Answer №1

When it comes to CSS, remember that it only styles the elements and won't change the actual content. You will have to handle value transformations yourself:

function updateText(){
  var input = document.getElementById("input");
  var textarea = document.getElementById("textarea");
  
  textarea.value = "Hello, my name is " + transformText(input.value);
}

function transformText(str) {
  return str.replace(/\b\w/g, function(char) { return char.toUpperCase(); });
}

input{margin-right:10px;float:left;text-transform:capitalize}textarea{height:30px;width:140px;float:left}

<input id="input" onkeyup="updateText()" placeholder="Enter Your Name"><textarea id="textarea"></textarea>

Would you like to give this a shot? I decided to make a simple change in the code by switching the textarea element to contenteditable for better styling. Additionally, I adjusted it to create a new element.

function updateText(){
  var input = document.getElementById("input");
  var editableContent = document.getElementById("editableContent");
    
  
  editableContent.innerHTML = "Hello, my name is <b id='name'>" + input.value + "</b>";
}

input{
  margin-right:10px;
  float:left;
}
#editableContent{
  height:30px;
  width:140px;
  float:left;
  border: 1px solid;
  font-family: Arial;
}
#name{
  text-transform: capitalize;
}

<html>
<body>
  <input id="input" onkeyup="updateText()" placeholder="Insert Your Name" />
  <div contenteditable="true" id="editableContent"></div>
</body>
