javascript function returnMultipleValues() { return { value1: 10, value2: 20, value3: 30 }; // 返回一个包含三个属性的对象 } var result = returnMultipleValues(); console.log(result.value1); // 输出: 10 console.log(result.v
在JavaScript中,return语句通常用于从函数中返回一个值。然而,有时我们需要从一个函数中返回多个值。有几种方法可以实现这一点: 1. 使用数组 你可以将多个值放入一个数组中,然后返回这个数组。 代码语言:txt 复制 function getMultipleValues() { let value1 = 10; let value2 = "Hello"; return [value1, ...
It wouldn’t sound too obvious but sometimes your function might need to return multiple values. For instance, in one of the applications I’m working on, I have a JavaScript function where I have to calculate two different values and return them. So, I needed to return two values from ...

以上就是实现“JavaScript return 中逗号”的完整代码。 4. 代码解释 在上面的代码中,我们创建了一个函数multipleValues,该函数返回两个字符串值。在函数体内,我们定义了两个变量value1和value2,并将它们分别赋值为 “Hello” 和“World”。在 return 语句中,我们使用逗号分隔了这两个变量,并将它们作为返回值。
Function with Return Multiple Values A function can also return multiple values. For example, func checkMarks() -> (String, Int) { ... return (message, marks) } Here, the return statement returns two values: message and marks. Also, -> (String, Int) specifies the return type message ...
Return values help demonstrate another reason why functions are such an important part of JavaScript. You can reuse the same function with different arguments to produce multiple return values. Next unit: Exercise - Create a function Continue
return values[position]; } } public bool MoveNext() { if (position != values.Length) { position++; } return position < values.Length; } public void Reset() { position = -1; } } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
Abandoning return values Modern promise-based or event-driven JavaScript no longer uses returned values. Have you noticed the following weird fact: as you get better at JavaScript, your code has fewer and fewer returned values? Remember your initial procedural code: 12345 function foo() { r...
Return ValuesThe void keyword, used in the previous examples, indicates that the function should not return a value. If you want the function to return a value, you can use a data type (such as int, string, etc.) instead of void, and use the return keyword inside the function:...
