spring mvc: How Can I give the <form:textarea /

Question

I have a problem with giving the <form:textarea /> tag a default value.
When I created a .jsp file as follow,

<form:textarea path="Content" id="my-text-box" />${content}

jsp parser translate the above line to:

<textarea id="my-text-box" name="Content"></textarea>third hello world!

Also, giving the value attribute does not work.

<form:textarea value="${content}" path="Content" id="my-text-box" />

jsp gives me as html output:

<textarea id="my-text-box" name="Content" value="third hello world!"></textarea>

you can see the <textarea> tag does not have the value attribute.

How can I pass a default value to <form:textarea> tag? Thank you in advance.

You have to use JS along with Spring MVC to make this work. This is what I did:

1. Change your textarea to basic html as below:

    <textarea id="myTextArea" onchange="here();">${content}</textarea>
     OR
    <textarea id="myTextArea" onchange="here();">third hello world!</textarea>
   

2. Add a hidden input field, using spring mvc:

   <form:input type="hidden" id="content" path="Content" value="third hello world!"/>
   

3. Add the following JavaScript:

   <script>
     var text1 = document.getElementById('myTextArea').value;
     function here() {
        text1 = document.getElementById('myTextArea').value;
        document.getElementById("content").value = text1;
     }
   </script>
