textarea assignment has a lot of spaces and blank lines

To write this:

<textarea id="planContent" ><c:out value="${planContent }"/></textarea>

 

Note that the textarea does not wrap and cannot be written in the following format

<textarea id="planContent" >

<c:out value="${planContent }"/>

</textarea>

Once the line is changed, it will cause spaces to appear. In addition, textarea has no value attribute and cannot be assigned by value.
