The While Loop Thewhileloop loops through a block of code as long as a specified condition is true. Syntax while(condition) { // code block to be executed } Example In the following example, the code in the loop will run, over and over again, as long as a variable (i) is less th...
In JavaScript the while loop is simple, it executes its statements repeatedly as long as the condition is true. The condition is checked every time at the beginning of the loop.Syntaxwhile (condition) { statements }Pictorial Presentation:Example: ...
loop 关键字告诉 Rust 一遍又一遍地执行一段代码直到你明确要求停止。Rust 提供了一种从代码中跳出循环的方法。loop 循环,相当于一个 while true,需要程序自己 break: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 fnmain(){letmut counter=0;letresult=loop{counter+=1;ifcounter==10{breakcounter*2;}...
While Loop TheJavaScript while loopconsists of a condition and the statement block. while (condition) {...statements...} The condition is evaluated. If the condition is true the statements are evaluated. If the statement is false we exit from the while loop. ...
在上面的示例中,我们定义了一个名为delayedWhileLoop的函数,它接受三个参数:condition(条件函数)、action(执行函数)和delay(延迟时间)。函数首先检查条件函数的返回值,如果为真,则执行执行函数,并在延迟时间后再次调用delayedWhileLoop函数。这样就实现了延迟执行While循环的效果。
JavaScript do keywordlast modified April 16, 2025 In this article we show how to use the do keyword to create do...while loops in JavaScript. The do...while loop executes a block of code at least once before checking the condition. ...
javascript let userInput = ""; while (userInput !== "exit") { userInput = prompt("Enter something (or 'exit' to quit):"); console.log("You entered: " + userInput); } console.log("Exiting the loop."); 在这个例子中,while循环会持续读取用户的输入,直到用户输入"exit"为止。
LoopHandler+input: String+runLoop() : void+exitLoop() : void 这个类包含一个input属性,用于处理用户输入,以及两个方法:runLoop用于执行循环,exitLoop用于终止循环。 结论 通过本文的介绍,我们详细探讨了JavaScript中的while循环及其跳出机制。while循环提供了简单而强大的方法来重复执行代码,而break语句则使我们能够...
JavaScript中的循环是一种重复执行特定任务的语句。它主要用于操作数组和类似数组的对象,比如字典、集合等。JavaScript提供了三种不同的循环控制语句:for循环、while 循环 以及 do-while 循环. For循环(for loop):for循环是最常用的循环控制语句,它可以在特定的范围内重复执行一定的代码。for语句的结构如下: ...
<!--var count = 0; document.write("Starting Loop"+""); while(count < 10){ document.write("Current Count : " + count + ""); count++; } document.write("Loop stopped!"); //--> 运行结果如下: Starting Loop Current Count : 0 Current Count...
