I'm trying to get write a simple jQuery plugin, I've come to a stumbling block though in that I'm not sure how to access variables on the plugin from within a method for that plugin.
(function($) {
$.fn.testPlugin = function() {
var testVar = "Hello World";
alert(testVar);
$.fn.testPlugin.testMethod();
};
$.fn.testPlugin.testMethod = function() {
alert($.fn.testPlugin.testVar);
};
}(jQuery));
$("body").testPlugin();
This code first alerts "Hello World" then "undefined" (so attempting to access it from within the method returns an empty variable), is there any way to access testVar from within the testMethod? Is this not possible? Am I going about this in the wrong way?
You are creating a local variable inside your first method. That makes it's scope restricted to the method itself.
Instead, you should actually create that variable with reference to the plugin like this :
$.fn.testPlugin.testVar = "Hello World";
