Adding a parameter to the handlestatechange(elementID) function

[ghepting]

I am working on a fairly simple implementation of ajax in a php shopping cart system.

 

What I am trying to do is modify the handlestatechange() function to accept a parameter so I can send the xmlHttp.responseText to a dynamically-assigned elementID (instead of assigning the data to the SAME element's innerHTML every time...)

 

I have a productID that php is getting from the mysql query and on the user-form there are 3 drop-menus that are also populated via php/mysql. These options are: Size, Color, & Quantity.

 

When any of the select boxes are changed I am using an xmlHttpRequest object to call a simple php page that queries the database with 4 parameters: The productID (unique and the key index), the size, the color, & the quantity. This returns only one value -- the PRICE of the item that matches the parameters that have been passed.

the handlestatechange()  can not take parameters because of it being an event.  What you must do is create a global level variable in js and then refer to it in the handlestatechange()  function.
