returning value from jQuery

[Mukhi Vla]

Hi all,

Can any one help in how to get value back from jQuery function?

My purpose is to get a selected value from list box when Button is clicked.

When I click on the button I am invoking a function , in that function i am able to alert the selected valu. But I want that value on .jsp page to set the selected value to session.

My code in .jsp page

<select id="width" name="width">
	<option value="12">12"</option>
	<option value="13">13"</option>
	<option value="14">14"</option>
	<option value="15">15"</option>
</select>

<button id="save" type="submit"> Save </button>

code from .js file

com.action.scaleWidth = (function (){
    $('#save').click(function (e){
	alert(' save clicked ' + $('#width').val());

    });

}());

how to get the selected width back to jsp file?

What do you mean by "back to the JSP file"?

I want to get the selected value on jsp page from the javascript function. To set that value to session.

By the time any JavaScript code runs on the client, the JSP that ran on the server is long gone.

You need to understand how JSP works to see why what you are asking makes no sense. Please read this article.

You'll need to call the server to set anything in session, either via Ajax or a form submission. As Bear says it'll be a good idea to understand the various life cycles involved in web apps before going too much further.

I got it. I will have to try AJAX. In my jsp I don't have any form submission. There is a href link that is redirected to a controller class. But before going to the controller I should have this value set.

Thanks
