jquery enter key trigger event implementation method

This article mainly shares with you an example of how jquery implements the enter key trigger event. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to take a look, I hope it can help everyone.

There are 3 keyboard events:

keydown, keypress, keyup, which are respectively pressing, pressing without lifting, and lifting the keyboard.

The correct code is:

$(document).keyup(function(event){
 if(event.keyCode ==13){
  $("#submit").trigger("click");
 }
});

Recommended: keyup to prevent the laptop keyboard from being accidentally touched

1. Some documents have it written like this:

$(window).keydown（function(){
...
}）

It is unsuccessful under IE6 under XP system.

2. There is also INPUT's

$("input").keydown（function(){
...
}）

In this case, keyboard events can only be monitored when the input gets focus.
