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
