How to trigger parent window element event in iframe

This time I will show you how iframe can trigger the parent window element event , what are the precautions for iframe to trigger the parent window element event, the following is a practical case, let’s take a look take a look.

For example, the parent window defines an event.

top:

$(dom1).bind('topEvent', function(){});

So how do the elements in the iframe trigger the event of the parent window dom1? Is that so?

$(dom1, parent.
document
).trigger('topEvent');

It seems correct, but it is actually misleading.

Because the jquery object of the parent window and the jquery object in the iframe are actually two objects (functions), the jquery in the iframe will not trigger another jquery Object defined events. Unless you define it in the iframe like this:

iframe:

self.$ = parent.$;

So the solution is very simple:

parent.$(dom1,parent.doucment).trigger('topEvent');

Just call the parent jquery to execute the event .

It is said that iframe should no longer need to import jquery files. It can just share the same jquery with the parent window. This is very environmentally friendly.
