Example(示例) 代码语言:javascript 代码运行次数:0 运行 AI代码解释 voidf(void);// badvoidg();// better Note(注意) Even Dennis Ritchie deemed void f(void) an abomination. You can make an argument for that abomination in C when function prototypes were rare so that banning: 哪怕丹尼斯·里奇...
For example, afunctionthat prints a message doesn't return a value. The code in C++ takes the form: void printmessage ( ) { cout << "I'm a function that prints a message!"; } int main ( ) { printmessage ( ); } A void function uses a heading that names the function followed ...
>function void(expr) { // 这里会报错 return undefined; } SyntaxError: Unexpected token void 1. 2. 3. 4. javascript中其他的关键字和保留字作为函数声明的函数名时也一样会报错。 void的三种用途: 用void 0代替undefined 书签小程序 在链接中执行JavaScript代码 ...

Unknown function is executed! Also, you can use the 'void' keyword with the arrow function to return undefined from the arrow function. The JavaScript:void() URI can also be used to prevent the web page reloading by default, like the preventDefault() method. ...
function example(param = void 0) //确保参数未传入时明确为undefined 超链接行为控制是void的经典应用场景。当需要在HTML锚点标签中阻止默认跳转行为时,开发者常使用javascript:void(0)作为href属性值。这种写法既执行了必要的JavaScript逻辑,又避免了页面跳转或刷新: 点击执行操作 立即执行函数表达式(IIFE)与void...
1. 使用 `window.open(url)`,如 `window.open('http://example.com')`。 2. 创建一个自定义函数,如: html function openWin(tag, obj) { obj.target = "_blank"; obj.href = "Web/Substation/Substation.aspx?stationno=" + tag; obj.click...
In this example, let's create a void function that generates a plot without returning anything −function plotSineWave() % Generate a sine wave and plot it x = linspace(0, 2*pi, 100); y = sin(x); % Plot the sine wave plot(x, y); title('Sine Wave'); xlabel('x'); ylabel...
