javascript - Javascript 条件可以在数字之间吗?

我希望根据此表确定一个类别: Table

我有一个 if 语句,它似乎适用于某些条件,但不适用于其他条件。 R、P 和 Q 有效,但数字之间的条件未返回正确的类别。

如果语句:

function getCategory(featureFunctionalScore, featureDysfunctionalScore) {
if (featureFunctionalScore == 4 && featureDysfunctionalScore == -2) {
return "Performance";
} else if (featureFunctionalScore == 4 && featureDysfunctionalScore <= -1 && featureDysfunctionalScore > 4) {
return "Attractive"
} else if (featureFunctionalScore <= -1 && featureFunctionalScore > 4 && featureDysfunctionalScore == 4) {
return "Expected"
} else if ((featureFunctionalScore >= -2 && featureFunctionalScore <= 2 && featureDysfunctionalScore == -2) || (featureFunctionalScore == -2 && featureDysfunctionalScore >= -2 && featureDysfunctionalScore <= 2)) {
return "Reverse"
} else if ((featureFunctionalScore == 4 && featureDysfunctionalScore == -2) || (featureFunctionalScore == 2 && featureDysfunctionalScore == -1) || (featureFunctionalScore == -1 && featureDysfunctionalScore == 2) || (featureFunctionalScore == -2 && featureDysfunctionalScore == 4)) {
return "Questionable"
} else {
return "Indifferent"
};
};

我错过了什么重要的东西吗?

更新此语句在 Excel 中有效,但我正在努力让它在 JS 中工作:

=IF(OR(AND(C3 <= 2, B3 <= -1), AND(C3 <= -1, B3 <= 2)), "R", IF(AND(C3 <= 2, C3 >= -1, B3 <= 2, B3 >= -1), "I", IF(AND(C3 >= 2,B3 >= -1, B3 <= 2),"A", IF(AND(C3 <= 2, B3 <= 4, B3 >= 2), "M", IF(AND(C3 >= 2, B3 >= 2), "P", "Q")))))

最佳答案

这应该是您要查找的内容。我确信它可以被优化,但它确实有效。 JSFiddle:https://jsfiddle.net/yxb7tr9n/

  function getCategory(x,y){
var answer = -999;

if (x == 4 && y == 4){
answer = "p";
}else if([-1,0,2].indexOf(x) >= 0 && y == 4){
answer = "A";
}else if((x == -2 && y == 4) || (x == -1 && y == 2) || (x == 4, y == -2)){
answer = "Q";
}else if(x == 4 && [-1,0,2].indexOf(y) >= 0) {
answer = "M";
}else if((x == -1 && [-1,0].indexOf(y) >= 0) || (x == 0 && [-1,0,2].indexOf(y) >= 0) || (x == 2 && [0,2].indexOf(y) >= 0)){
answer = "I";
}else if ((x == -2 && [-2,-1,0,2].indexOf(y) >= 0) || (y == -2 && [-2,-1,0,2].indexOf(x) >= 0)) {
answer = "R";
}else{
answer = "??";
}

return answer;
}

更新:使用坐标映射系统的替代版本。 JSFiddle:https://jsfiddle.net/g2d6p4rL/4/

  function indexOfCustom (parentArray, searchElement) {
for ( var i = 0; i < parentArray.length; i++ ) {
if ( parentArray[i][0] == searchElement[0] && parentArray[i][1] == searchElement[1] ) {
return i;
}
}
return -1;
}

function getCategory2(x,y){
var p = [[4,4]];
var q = [[-2,4],[-1,2],[2,-1],[4,-2]];
var a = [[-1,4],[0,4],[2,4]];
var m = [[4,2],[4,0],[4,-1]];
var i = [[0,2],[2,2],[-1,0],[0,0],[2,0],[-1,-1],[0,-1]];
var r = [[-2,2],[-2,0],[-2,-1],[-2,-2],[-1,-2],[0,-2],[2,-2]];

coord = [x,y];

if (indexOfCustom(p,coord) >= 0){
return "p";
} else if (indexOfCustom(q,coord) >= 0){
return "Q";
} else if (indexOfCustom(a,coord) >= 0){
return "A";
} else if (indexOfCustom(m,coord) >= 0){
return "M";
} else if (indexOfCustom(i,coord) >= 0){
return "I";
} else if (indexOfCustom(r,coord) >= 0){
return "R";
}else{
return "??";
}
}

所有答案的输出:

[-2,-2] = R
[-2,-1] = R
[-2,0] = R
[-2,2] = R
[-2,4] = Q
[-1,-2] = R
[-1,-1] = I
[-1,0] = I
[-1,2] = Q
[-1,4] = A
[0,-2] = R
[0,-1] = I
[0,0] = I
[0,2] = I
[0,4] = A
[2,-2] = R
[2,-1] = Q
[2,0] = I
[2,2] = I
[2,4] = A
[4,-2] = Q
[4,-1] = M
[4,0] = M
[4,2] = M
[4,4] = p
