Setting up a bunch of listeners with a looping structure

Setting up a bunch of listeners with a looping structure

Hi everyone,

I'm trying to come up with a better architecture for dealing with multiple listeners in a multi-page questionnaire. Here's the general structure I'm looking to implement:

1. Set up CSS for animation
2. Look for preconditions
3. Initialize listener
4. Execute animation

Some issues to consider:

1. Some questions have dependencies that show or hide depending on what is selected in a parent question.
2. Needs to be IE 6 compatible.
3. It should be simple enough so that all you need to do is add a new question to a JSON object, which is what I have set up right now.

Some code (the looping structure that reads each question):
  1.     var newQ = eval(q);   
       
        $.each(newQ, function () {
            // 1 - Setting CSS for each listener
            $(this.css).css({'width': '1500px', 'float': 'left', 'clear':'both'});
            // 2 - Applying pre-conditions
            if (this.value.length > 1) {
                // handle multiple checkbox conditionals
            }
            else {
                if ($('[name="'+this.name+'"]:checked').attr('value') != this.value) $('#'+this.eid).hide();
            }
        });











An example of a question with dependencies and multiple conditionals. Each value represents a checkbox that needs to be checked to see if it's selected or not.
  1.     {
            'key': '2030',
            'name': 'q2030',
            'value': [
                'value1',
                'value2',
                'value3',
               ...






  2.          'value8'
            ],
            'css': '#_layoutCSS',
            'eid': 'hideme',
            'toggle': 'false'
        },





The problem here is that when I do a console.dir on $.each(this.value.length), it counts each character, as opposed to counting the number of elements in the array. Should I be doing an eval on q? Why or why not? If I could get this up and running, it would make my life 100x easier, as there are hundreds of questions, and I'd want to make this all data driven.

Thanks!
