Jquery multiple browsers capture carriage return Event code _ jquery

Recently, a cooperation project on our website requires that the carriage return event be captured on the page. After many tests, we found this The Code is as follows:

$ (Document). keydown (function (event ){
If (event. keyCode = 13 ){
$ ('Form'). each (function (){
// Your code to run
});
}
});

However, it still does not work in opera, and it is poor in technology. In one breath, the carriage return event is blocked.



This may be helpful for some features. But I just want to help some people.
