此外,将focus()包装在超时中的下一个元素上(角度版本为$timeout或vanillajs为setTimeout),因此焦点将在另一个范围内执行,并且在模糊完成后执行.

你应该有这样的东西：

$scope.inputKeyEvent = function(event,id) {
    // prevent default 
    event.preventDefault();

    // blur on the unfocused element
    event.target.blur();

    // focus on next element
    // wrapped in timeout so it will run
    // in "another thread" 
    $timeout(function() {
      // If you want to follow all angular best practices
      // Make a broadcast and read the event in the link function
      // of your directive
      var obj = document.getElementById(nextId);

      // Check if object exists
      if(obj) {
       obj.focus();
      }

    });
}
