jQuery text box (input textare) event binding method tutorial_jquery

Currently 1.7 or above, jquery​’s event binding has replaced the original bind with on. Next, I will introduce how to use bind and the input textare event. Interested friends can refer to

(1) jquery binding event
Currently 1.7 or above, jquery’s event binding has replaced the original bind with on;
Difference: (personal understanding) bind is a binding event to each child Node; on is only bound to the parent node, and then bubbles to each child node;

Usage: bind
One event, one method: $(".class input").bind('click ',function(e){...;e.stopPropagation;})
Two events, one method: $(".class input").bind('click mouseover',function(e){.. .;e.stopPropagation;})
Two events, two methods: $(".class input").bind({ click:function(e){...;e.stopPropagation;}, mouseover: function(e){...;e.stopPropagation;} })
on, you can directly replace bind, which means that the above usage is applicable to on;
In addition, on has two more options than bind Selection parameters
on( events [, selector ] [, data ], handler(eventObject) )

selector: the element to be bound. The above example can be written as: $(".class"). bind('click','input',function(e){...;e.stopPropagation;})
(It should be noted that there is an event that is not easy to use, which is unique to 'Shit' ie Event: onpropertychange;
Can be used: $(".class input").bind('propertychange',function(e){...;e.stopPropagation;})
No response: $(". class").bind('propertychange','input',function(e){...;e.stopPropagation;})
)

data: parameters passed to event.data, $ (".class").bind('click','input','123',function(e){alert(e.data/*123*/);e.stopPropagation;})
(more specific For usage, please check the manual http://api.jquery.com/on/);

(2) input textare event
before making a text box content real-time change event when the event is triggered , use onkeyup onchange; but onchang will only be triggered after the text box is out of focus. Later I found that it can be handled with
(if IE) onpropertychange else oninput.

Note:
The oninput event is triggered when the user inputs, backspaces, deletes, cuts, pastes, and mouse cuts and pastes (it may be slightly different in IE9&IE9).
(Firefox, Chrome, IE9 & IE9 all support)
onpropertychange event is triggered when user input, backspace, delete, cut, paste and mouse cut and paste
(only supported by IE).
