javascript

JS is a method for judging whether the keyboard presses the enter key and triggering the designated button click operation

Examples are as follows:

document.onkeydown = function (e) {
      if (!e) e = window.event;
      if ((e.keyCode || e.which) == 13) {
        var obtnLogin = document.getElementById("submit_btn");  //submit_btn For buttons ID
        obtnLogin.focus(); 　　　　　　　　　  fun();// Method triggered by submit button
      }
    }
