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 t...
functionmultipleValues(){letvalue1="Hello";letvalue2="World";returnvalue1,value2;} 1. 2. 3. 4. 5. 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...

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...
{object[] values =newobject[] {1,2,3}; MyEnumerator it=newMyEnumerator(values);while(it.MoveNext()) { Console.WriteLine(it.Current); } } 这个例子很简单,也很容易实现,现在假设同时有两个线程去迭代这个集合,那么使用一个MyEnumerator对象明显是不安全的,这正是IEnumerable存在的原因,它允许多个调用者...
However, when I edit multiple cells at once (e.g., deleting values into a range), the details object is undefined. This makes it impossible to track value changes for multiple-cell edits. So below I attached the Screenshot of both the differences. ...
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:...
