--description--
如果你有多个条件语句,你可以通过else if
语句把if
语句链起来。
if (num > 15) {
return "Bigger than 15";
} else if (num < 5) {
return "Smaller than 5";
} else {
return "Between 5 and 15";
}
--instructions--
使用if else
实现同样的效果。
--hints--
你应该至少有两个else
表达式。
assert(code.match(/else/g).length > 1);
你应该至少有两个if
表达式。
assert(code.match(/if/g).length > 1);
testElseIf(0)
应该返回 "Smaller than 5"。
assert(testElseIf(0) === 'Smaller than 5');
testElseIf(5)
应该返回 "Between 5 and 10"。
assert(testElseIf(5) === 'Between 5 and 10');
testElseIf(7)
应该返回 "Between 5 and 10"。
assert(testElseIf(7) === 'Between 5 and 10');
testElseIf(10)
应该返回 "Between 5 and 10"。
assert(testElseIf(10) === 'Between 5 and 10');
testElseIf(12)
应该返回 "Greater than 10"。
assert(testElseIf(12) === 'Greater than 10');
testElseIf(12)
应该返回 "Greater than 10"。
assert(testElseIf(12) === 'Greater than 10');

--seed-contents--
function testElseIf(val) {
if (val > 10) {
return "Greater than 10";
}
if (val < 5) {
return "Smaller than 5";
}
return "Between 5 and 10";
}
testElseIf(7);
--solutions--
function testElseIf(val) {
if(val > 10) {
return "Greater than 10";
} else if(val < 5) {
return "Smaller than 5";
} else {
return "Between 5 and 10";
}
