如何使此错误消息不打印两次？(如何让ng-keypress不触发ng-blur)

<input type="text" ng-keypress="handleKeyPress($event)" ng-blur="handleBlur()" />

$scope.handleKeyPress = function(event) {
    event.stopPropagation();
    // 处理按键逻辑
};

$scope.handleBlur = function() {
    // 处理失焦逻辑
};

<input type="text" ng-keypress="handleKeyPress()" ng-blur="handleBlur()" />

$scope.handleKeyPress = function() {
    // 处理按键逻辑
};

$scope.handleBlur = function() {
    var self = this;
    $timeout(function() {
        // 处理失焦逻辑
    }, 0);
};

<input type="text" ng-model="myModel" ng-model-options="{ updateOn: 'default blur', debounce: { default: 500, blur: 0 } }" />

<input type="text" ng-keypress="handleKeyPress()" ng-blur="handleBlur()" />

$scope.handleKeyPress = function() {
    // 处理按键逻辑
};

$scope.handleBlur = function() {
    // 处理失焦逻辑
};
