Distinguish jQuery from prototype

First of all, in jquery, any selection of elements is done by calling $("selector") in prototype $("selector") is the same as document.getElementById("selector") .

For non-id samples in prototype, $$("selector") , here it is.

The prototype handler is initialized as follows:

 Event.observe(element, "eventName", function(e){}); // на element навешиваем обработчик события eventName, в нашем случае это анонимная функция // либо element.observe("eventName", function(e){}); // на элемент element - событие eventName // либо Event.observe("elementId", "eventName", function(e){}) 

For example, to handle a window load event, you can use the following construction

 Event.observe(window,"load",function(){}); 

Well, the creation of classes in prototype:

 var ClassName = Class.create({ initialize: function(){} // ..... }) 

Well, in prototype, the ajax API is completely different, an example of a prototype ajax request:

 new Ajax.Request("requestUrl",{ parameters: { someKey: "someValue" }, onSuccess: function(request) { // request - объект xmlHtppRequest // соответственно ответ сервера например храниться в request.responseText // пример преобразования json ответа var fromJson = request.responseText.toJSON(true); }, onFailure: function(){}; // обработчик фейла ^^ }); 

It's generally quite simple to distinguish between jquery code and prototype code. JQuery "imposes" the use of its functions and in fact, as it were, "leaves" from native javascript. Thus, in jquery code, you will hardly see anything other than calling jquery or user-defined functions.

As for the prototype code - in the part of the code the prototype methods are used, in part - the native js (or user methods, classes, events, etc.)

If you have any questions please ask.

PS: I didn't write about jquery. usually all one way or another, this framework is known
