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标签定义了一个多行纯文本编辑控件。由于文本空间可以容纳无限数量的字符(通常是Courier),所以文本以固定宽度字体显示。在表单中,textarea通常用于收集用户输入,例如评论或评价。在提交表单后,表单数据中的引用将需要name属性。

Let’s look into the following examples to know more about how do we display a textarea in HTML.

Example 1

在下面的示例中,我们使用了多行输入控件。

<!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>

在运行上述脚本时,输出窗口弹出,显示了用于输入姓名的输入字段和用于自我介绍的文本区域,以及一个提交按钮。如果您点击提交按钮,表单将被提交。

Example 2:使用JavaScript

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>
当脚本被执行时,它会生成一个输出,其中包含一个填充有文本的地址字段的文本区域,以及一个点击更改按钮

If the user clicks on the button, the text in the textarea gets changed.

Example 3

的中文翻译为:

让我们考虑另一个例子,我们正在使用textarea标签

<!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.
