The task we are going to perform in this article is how do we display a text area in HTML. Let's dive into the article for getting a clear idea on how we display text area.
HTML textarea標籤定義了一個多行純文字編輯控制項。由於文字空間可以容納無限數量的字元（通常是Courier），所以文字以固定寬度字體顯示。在表單中，textarea通常用於收集使用者輸入，例如評論或評價。在提交表單後，表單資料中的參考將需要name屬性。
Let’s look into the following examples to know more about how do we display a textarea in HTML.
在下面的範例中，我們使用了多行輸入控制項。
<!DOCTYPE html>
<html>
<body>
<form action="https://www.tutorialspoint.com/index.htm">
<label for="name">NAME:</label><br>
<input type="text" id="name" name="name"><br>
<p><label for="comment">About Yourself:</label></p>
<textarea id="comment" name="comment" rows="5" cols="35">
I'm from Hyderabad,Telengana
</textarea><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
在執行上述腳本時，輸出視窗彈出，顯示了用於輸入姓名的輸入欄位和用於自我介紹的文字區域，以及一個提交按鈕。如果您點擊提交按鈕，表單將會提交。
Considering the following example we are running script to change the context in the text area.
<!DOCTYPE html>
<html>
<body>
Address:<br>
<textarea id="tutorial">
kavuri incore 9
Hyderabad
</textarea>
<button type="button" onclick="myFunction()">Click To Change</button>
<script>
function myFunction() {
document.getElementById("tutorial").value = "Madhapur , Telangana";
}
</script>
</body>
</html>
If the user clicks on the button, the text in the textarea gets changed.
讓我們考慮另一個例子，我們正在使用textarea標籤
<!DOCTYPE html>
<html>
<head>
<title>HTML textarea Tag</title>
</head>
<body>
<form action = "/cgi-bin/hello_get.cgi" method = "get">
Enter subjects
<br/>
<textarea rows = "5" cols = "50" name = "description"></textarea>
<input type = "submit" value = "submit" />
</form>
</body>
</html>
When the script gets executed, the output window will pop up, providing the input type for textara along with a submit button.
