我正在try 赋予我的插件回调功能，我希望它能以一种有点传统的方式运行:
myPlugin({options}, function() {
/* code to execute */
});
或
myPlugin({options}, anotherFunction());
How do I handle that parameter in the code? Is it treated as one full entity? I'm pretty sure I know where I'd place the execut或y code, but how do I get the code to execute? I can't seem to find a lot of literature on the topic.
Just execute the callback in the plugin:
$.fn.myPlugin = function(options, callback) {
if (typeof callback == 'function') { // make sure the callback is a function
callback.call(this); // brings the scope to the callback
}
};
您还可以在options对象中使用回调:
$.fn.myPlugin = function() {
// extend the options from pre-defined values:
var options = $.extend({
callback: function() {}
}, arguments[0] || {});
// call the callback and apply the scope:
options.callback.call(this);
};
Use it like this:
$('.elem').myPlugin({
callback: function() {
// some action
}
});
