Question

Good afternoon people’s

I have built a jquery plugin that I use on my site. The plugin is for suggestive input boxes and works fine.

One thing I need to add to it is the ability to pass a function in it’s config to apply to the response of the ajax call that is made for the suggestive. I can’t find anything on trusty old google about how to pass functions and have them applied in the scope of the plugin..

I need this because some responses update one field and some update 2 or more fields with different text held in the reponse and I dont want to keep duplicating the plugin allowing for this to happen. I am assuming that the javascript method “apply” is what I need to look at but I am totally confused

Does this even make sense on what I am trying to do ? and if so can anyone help or point me in the right direction.

Thanks in advance

Answer 1

You are looking for .call() or .apply(). You can pass the context (i.e. scope) as the first parameter to both. .call() works like this:

yourCallback.call(this, param1, param2);

While .apply() works like this:

yourCallback.apply(this, [param1, param2]);

.apply() is very helpful when generating the parameters dynamically.
