翻译强力驱动I'd like to call a simple YUI3 function from within a JavaScript function. Here is some code that does what I want in a very verbose way:
function changeContent (message) { YUI().use("node", function(Y) { Y.all('#content-div').setContent(message); }); }Is there a better way to do this?
NOTE: I don't want to attach this function to any event, I just want a global changeContent() function available.
If you want the API to exist outside of the YUI().use(...function (Y) { /* sandbox */ }), you can capture the returned instance from YUI().
(function () { // to prevent extra global, we wrap in a function var Y = YUI().use('node'); function changeContent(message) { Y.one('#content-div').setContent(message); } ... })();Be aware that there is a race condition here if you use the seed file (yui-min.js) and dynamic loader to pull in the other modules. changeContent could be called before the Node API is loaded and added to Y. You can avoid this by using a combo script up front. You can get the combo script url from the YUI 3 Configurator. There is a performance penalty for loading the modules in a blocking manner up front. You may or may not notice this in your application.
You can do like this:
(function(){ YUI().use("node", function(Y) { APP = { changeContent: function(message){ Y.all('.content-div').setContent(message); } }; }); })();Then, you can call changeContent by calling APP.changeContent(message); from anywhere you want. Hope this helps. :D
