hi guys, Consider this scenario in relation to a blog posting application.
- a form has been loaded for a user to create a new blog entry - attributes are: title, content, category and sub-category -user goes ahead and fills in text to the title and content attributes - user selects an option from the drop down (select) box representing the 'category' attribute. Possible values are: "politics", "finance" and "entertainment". - upon selecting a category value, the "sub-category" attribute's drop down (select) should be populated. For example, if a user selects "politics", the sub-categories that can be selected are: "US,AU,NZ" whilst when "finance" is selected, the sub-categories that can be selected are: "mining", "bonds" and "interest rates" and when "entertainment" is selected as a category, the sub-categories that can be selected are: "sports", "music" and "theatre". I know that the scenario above would have Ajax as its' solution. Roughly, I figure it would be the case that the onChange javascript attribute is to be used on the category select box. When the value changes, an Ajax request is made to the necessary controller and the controller will return the sub-category values of the selected category. Has anyone got a link to a good tute I can look at? I read the rails books i have but I can't find anything similar to this.
