我正在尝试使用两个按钮创建一个输入字段,这将在输入字段中添加和分散数字1。
一切正常,但当我尝试直接在输入字段中更改数字时,按钮停止工作
function Ctrl($scope) {
$scope.Score1 = 0;
$scope.$watch('Score1', function (newVal) {
$scope.Score1 = newVal;
console.log(newVal);
});
$scope.add_btn = function() {
$scope.Score1 ++;
};
$scope.dist_btn = function() {
if ($scope.Score1 > 0) {
$scope.Score1 --;
} else {
$scope.Score1 = 0;
}
};
}
