jQuery Event Keypress Which key was pressed

Question

With jQuery  how do I find out which key was pressed when I bind to the keypress event       searchbox input   bind  keypress   function e         I want to trigger a submit when ENTER is pressed    Update   Even though I found the  or better  one  answer myself  there seems to be some room for variation     Is there a difference between keyCode and which - especially if I m just looking for ENTER  which will never be a unicode key   Do some browsers provide one property and others provide the other one

If you are using jQuery UI you have translations for common key codes  In ui ui ui core js     ui keyCode                  ENTER  13                There s also some translations in tests simulate jquery simulate js but I could not find any in the core JS library  Mind you  I merely grep ed the sources  Maybe there is some other way to get rid of these magic numbers   You can also make use of String charCodeAt and  fromCharCode       String charCodeAt   r      13 true     String fromCharCode 13       r  true

Use event key and modern JS  No number codes anymore  You can check key directly  For example  quot Enter quot    quot LeftArrow quot    quot r quot   or  quot R quot   const input   document getElementById  quot searchbox quot    input addEventListener  quot keypress quot   function onEvent event        if  event key      quot Enter quot                Submit           else if  event key      quot Q quot                Play quacking duck sound  maybe               Mozilla Docs Supported Browsers

Given that you are using jQuery  you should absolutely use  which   Yes different browsers set different properties  but jQuery will normalize them and set the  which value in each case   See documetation at http   api jquery com keydown  it states           To determine which key was pressed  we can examine the event object that is passed to the handler function  While browsers use differing properties to store this information  jQuery normalizes the  which property so we can reliably use it to retrieve the key code

Given that you are using jQuery  you should absolutely use  which   Yes different browsers set different properties  but jQuery will normalize them and set the  which value in each case   See documetation at http   api jquery com keydown  it states           To determine which key was pressed  we can examine the event object that is passed to the handler function  While browsers use differing properties to store this information  jQuery normalizes the  which property so we can reliably use it to retrieve the key code

If you are using jQuery UI you have translations for common key codes  In ui ui ui core js     ui keyCode                  ENTER  13                There s also some translations in tests simulate jquery simulate js but I could not find any in the core JS library  Mind you  I merely grep ed the sources  Maybe there is some other way to get rid of these magic numbers   You can also make use of String charCodeAt and  fromCharCode       String charCodeAt   r      13 true     String fromCharCode 13       r  true
