通过 JSP 在脚本上获取 textarea 编辑的文本

Question

I need to get the text a user enters in a textarea, in a script from JSP. I tried this code but get null value:

<label for="userText"></label>
<textarea name="userText" id="userText">text edited by the user</textarea>
<button onclick="myFunction()">Ok</button>

function myFunction() {
    <%System.out.print(request.getParameter("userText"));%>
}

I can i get it?

You will have to use Java Script for this

var message = $('textarea#userText').val();
