I am just starting out with writing jQuery plugins. I wrote three small plugins but I have been simply copying the line into all my plugins without actually knowing what it means. Can someone tell me a little more about these? Perhaps an explanation will come in handy someday when writing a framework 🙂
What does this do? (I know it extends jQuery somehow but is there anything else interesting to know about this)
(function($) {
})(jQuery);
What is the difference between the following two ways of writing a plugin:
Type 1:
(function($) {
$.fn.jPluginName = {
},
$.fn.jPluginName.defaults = {
}
})(jQuery);
Type 2:
(function($) {
$.jPluginName = {
}
})(jQuery);
Type 3:
(function($){
//Attach this new method to jQuery
$.fn.extend({
var defaults = {
}
var options = $.extend(defaults, options);
//This is where you write your plugin's name
pluginname: function() {
//Iterate over the current set of matched elements
return this.each(function() {
//code to be inserted here
});
}
});
})(jQuery);
I could be way off here and maybe all mean the same thing. I am confused. In some cases, this doesn’t seem to be working in a plugin that I was writing using Type 1. So far, Type 3 seems the most elegant to me but I’d like to know about the others as well.
