Get JavaScript dynamic variable

    Hi. My knowledge of javascript are limited and I bumped into a simple thing today , but it seems that I can get it done.

    I've got a javascript file , and to the top of this I have something like:

    
var options = {
    "background":{
        "colour":"red",
        "pattern":"lines"
    },
    "text":{
        "style":"bold",
        "arrange":"middle"
    }
};
    Code (markup):
    So , what I'm trying to do is to take each key's value: Eg. options -> background -> colour and I should get "red".

    It works well if I use with an alert like:

    alert(options.background['colour']);
    Code (markup):
    but how would I get that value to this (eg. flexslider's atributes ) :

    
    $('#blog-slider').flexslider({
            slideshow: true,
            background: "red" //  where 'red' will be the value from options.background['colour']
    });
    Code (markup):
    (There's no attribute for flexslider "background" , but is just an example)
    Probably it's a simple thing , but a little help will be great.

    $('#blog-slider').flexslider({
            slideshow: true,
            background: options.background.colour
});
    Code (markup):
    ... or am I something missing?

    PS: calling the
     var colour = options.background.colour;
    Code (markup):
    is the same as

     var colour = options.background['colour'];
    Code (markup):
    there is no reason to write code like in second example

    one more thing. To play with javascript press: Ctrl+Shift+J
    javascript console will pop up (in firefox and chrome) and you can play with javascript and learn how things works.
    keep it up, don't give up ;) God Bless

    Pls adjust your options object to some thing like this

    
var options = { 
   background: { 
      colour: "red",
      pattern: "lines" 
      text: { 
         style: "bold",   
         arrange: "middle"
      }
    Code (markup):
    to give your $('#blog-slider') jquery object the red options property, do it like this 

    
$('#blog-slider').prop(flexslider).prop(background) = options.background.color;
    Code (markup):
    NOTE: you use the prop() function to access jquery object properties.

    hope this helps:)

    I can't get options object like this, because it's generated automatically by a WordPress function (wp_localize_script) inside the <head></head> tags and I can't edit this.


    Thanks both for your answers , I've managed to do this. The problem seemed to be in a php array that was generating this object.
