js method to implement keyboard Enter key to submit form_javascript skills

The example in this article describes how to implement the keyboard Enter key to submit a form using js. Share it with everyone for your reference. The specific implementation method is as follows:

//执行键盘按键命令
function keyDown(e){ 
 var keycode = 0;
 //IE浏览器
 if(CheckBrowserIsIE()){
  keycode = event.keyCode;
 }else{
 //火狐浏览器
 keycode = e.which;
 }
 if (keycode == 13 ) //回车键是13
 {
  //document.getElementById("login").click();
  document.getElementById("loginform").submit();
 }
}
//判断访问者的浏览器是否是IE
function CheckBrowserIsIE(){
 var result = false;
 var browser = navigator.appName;
 if(browser == "Microsoft Internet Explorer"){
  result = true;
 }
 return result;
}

Finally, you only need to add to the body: 1aef1d3a19cadeceb602e71375851bc9.

Or the following method, but it is not compatible with Firefox:

function document.onkeydown(){  
 if(event.keyCode==13)  
 document.getElementById('loginFrom').submit();
}

I hope this article will be helpful to everyone’s JavaScript programming design.
