How do I show text in text field? - html

Question

I used <s:iterator> tag to display checkboxs and text fields:
<s:iterator value="paramMapSimple" var="param" status="iteratorStatus">
<tr>
<td>
<input type="checkbox" name="params" key_id="<s:property value="#iteratorStatus.index "/>" value = "<s:property value="#param.key "/>"
<s:iterator value="params" var="app">
<s:if test="#app.substring(0,1)==#param.key">
checked
</s:if>
</s:iterator>/>
</td>
<td>
<input type="text" text_id="<s:property value="#iteratorStatus.index "/>" >
</td>
</tr>
params of type String[] stores the index and input text which have been checked, e.g., if the first and second checkboxes are checked, and the user input "paramName1" and "paramName2" in the text field, respectively, then params is: {1#paramName1, 2#paramName2}, and if the user check a checkbox but doesn't input anything, then default value will be stored, e.g., if the first and second checkboxes are checked, and the user only input "paramName1" for the first checkbox, then params is: {1#paramName1, 2#defaultParamName2}.
What I want is: if a checkbox is checked, then the text field shows the text input by the user (if the user doesn't input, shows the default value), otherwise, shows the default value.

In HTML, you can actually use a textarea:
For example:
<textarea rows="4" cols="50">
The text you want to put here!
</textarea>
You can refer to HTML textarea tag
You can also use a placeholder:
For example:
<form action="submit.php">
<label for="phone">Enter a phone number:</label><br><br>
<input type="tel" id="phone" name="phone" placeholder="123-45-678"
pattern="[0-9]{3}-[0-9]{2}-[0-9]{3}"><br><br>
<small>Format: 123-45-678</small><br><br>
<input type="submit">
</form>
This will generate a hint text in the textbox!
