Question

I am writing a jQuery plugin. There are some default options and I can change them on HTML, but how can I change an option if it consists of an array?

Here is the code in plugin:

(function($){    
    $.fn.extend({  
        aniTag: function(options) {     
            var defaults = {
                radius: 25,
                defaultradius: 0,
                enableTilt: true,
                tilt : 20,
                random : true, 
                randomMax : 25 ,
            };

            var colors = new Array('4AC7ED', 'FDC015', '9F78EC', 'F25C33');         

            var options = $.extend(defaults, options); 

            return this.each(function() {                
                var o = options;
                //some stuff
            });
        }
    });  
})(jQuery);

Here is the html usage:

<script type="text/javascript">
    $(document).ready(function() {
        $('.tags').aniTag({enableTilt: false});
    });
</script>

As you can see I can change enableTilt option. What I need to do is to change the values in the color array. Yes, I know I need to put that array in defaults var, but I don’t know how to do it.

Answer 1

Add your array of colors to your defaults like so

var defaults = {
    radius: 25,
    defaultradius: 0,
    enableTilt: true,
    tilt : 20,
    random : true, 
    randomMax : 25 ,
    colors: ['4AC7ED', 'FDC015', '9F78EC', 'F25C33']
};

Then you can overwrite them with

$('.tags').aniTag({enableTilt: false, colors: ['ffffff', '000000']});

Fiddle Demo: http://jsfiddle.net/Beufe/1/

var defaults = {
    radius: 25,
    defaultradius: 0,
    enableTilt: true,
    tilt: 20,
    random: true,
    randomMax: 25,
    colors: ['4AC7ED', 'FDC015', '9F78EC', 'F25C33']
};

alert(defaults.colors.length);  // output: 4
alert('Default Value colors[0] = ' + defaults.colors[0]);  // output: 4AC7ED

var options = $.extend(defaults, {
    enableTilt: false,
    colors: ['ffffff', '000000']
});

alert(options.colors.length);  // Output: 2
alert('New Value colors[0] = ' + options.colors[0]);  // output: ffffff
