Get value from jstl text field through jQuery

Question

I am working on a project in spring with jstl and jQuery. I have a text field in jsp page as -

<form:input path="suv.userName" cssClass="textField" placeholder="Username (Email-Id)"/>

Problem is - when i am trying to get the field value through jQuery as - alert($("#suv.userName").val()); I am getting the undefined message. But when i am trying with javascript as -

alert(document.getElementById("suv.userName").value);

I am getting the proper value. I think there is something problem in suv.userName haveing a '.' between. Please help how to get the value in jQuery.

@Felix kling The question that you have linked looks like a vague one.. :( — Rajaprabhu Aravindasamy, Jun 14 '14 at 07:21
@RajaprabhuAravindasamy: Really? I think it's pretty clear. The other question is about using an ID containing a `.` in a jQuery selector. What's vague about that? — Felix Kling, Jun 14 '14 at 07:23
@FelixKling yeah, I agree with it now. I just had a closer look.. — Rajaprabhu Aravindasamy, Jun 14 '14 at 07:26

Since . is a meta-character you have to escape it with \\ in order to make that selector valid.

Try,

alert($("#suv\\.userName").val());
