I need to pass input field value from visual force page to the controller. This input value is not belongs to any object. It just a normal input value.

The bindings doesn't require an object to work, just getters and setters. Let's suppose you want to ask for the user name, and store it in a variable.

The controller has to have the variable to store the name:

public String userName {get;set;}

And the visualforce page just need to have an apex:inputfield pointing to that variable:

<apex:inputfield value="{!userName}" />

If you want to pre populate that variable so the input displays something when the page loads just set the value on the constructor.

I am struggling with the same issue today and still haven't found a general solution to that which I can simply set the value in javascript. However, this blog post: http://bobbuzzard.blogspot.com.au/2011/07/passing-parameters-to-apex-method-from.html will probably help.

Create a controller extension class and in the extension class create a property for your variable.

Essentially use a wrapper class. You can then access the value in VF using

{!var}

and in your extension class, you can access it as var.
