如何在angularjs中显示负数为正数

Question

我有来自服务器的$ http.Get数据。我有一个功能来获得总价值。它工作正常，总值为负（-370）。但是当我使用它制作角度图时，我需要显示为正数。任何人都可以帮助我吗？

public class QuizActivity extends AppCompatActivity {
private Button mTrueButton;
private Button mFalseButton;
private Button mNextButton;
private TextView mQuestionTextView;
private Question[] mQuestionBank= new Question[]{
        new Question(R.string.question_oceans, true),
        new Question(R.string.question_mideast, false),
        new Question(R.string.question_africa, false),
        new Question(R.string.question_americas, true),
        new Question(R.string.question_asia, true),
};
private int mCurrentIndex = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_quiz);
    mQuestionTextView = (TextView) findViewById(R.id.question_text_view);
    int question = mQuestionBank[mCurrentIndex].getTextResId();
    mQuestionTextView.setText(question);
    mTrueButton = (Button) findViewById(R.id.true_button);
    mFalseButton = (Button) findViewById(R.id.false_button);

    mTrueButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(QuizActivity.this,R.string.correct_toast,Toast.LENGTH_SHORT).show();
        }
    });
    mFalseButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(QuizActivity.this,R.string.incorrect_toast,Toast.LENGTH_LONG).show();
        }
    });
}    

提前感谢!!

在sum函数中，在返回值之前获取总金额的absolute value：

arrayWithValuesByTwo(1)

您可以使用Math.abs（）函数 Math.abs(number)
