jQuery supports the way dynamic parameters bind functions to events

This article demonstrates how jQuery supports dynamic parameters for binding functions to events. Share with you for your reference. The specific analysis is as follows:

The js code below provides two methods for binding functions to events, of which method 2 is very useful for passing dynamic parameters

// methods 1
$('#foo').click(function(event) {
　　alert('User clicked on "foo."');
}); 
 
// methods 2,  Support dynamic parameter transfer 
$('#foo').bind('click', {test1:"abc", test2:"123"}, function(event) {
　　alert('User clicked on "foo."' + event.data.test1 + event.data.test2);
});

I hope this article is helpful for you to design jQuery program.
