do{ // code block to be executed } while(condition); Example The example below uses ado whileloop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested: ...
In JavaScript do while loop executes a statement block once and then repeats the execution until a specified condition evaluates to false. Syntax do { statement block } while (condition); In while loop, the given condition is tested at the beginning, i.e. before executing any of the statemen...
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. The do keywordThe do keyword is used to create a do...while loop in JavaScript. This loop executes ...
JavaScript do...while Loop The do...while loop executes a block of code once, then repeatedly executes it as long as the specified condition is true. The syntax of the do...while loop is: do { // body of loop } while(condition); Here, The do…while loop executes the code inside...

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: ...
JavaScript 循环 while和do while循环语句 在程序开发中,存在大量的重复性操作或计算,这些任务必须依靠循环结构来完成。JavaScript 定义了while、for和do/while三种类型循环语句。 while语句 while 语句是最基本的循环结构。语法格式如下: while (expr) statement ...
JavaScript语句之whiledo while循环 while与do while也是我们项目上会使用到的语句,都是循环,但是有区别,下面就说说两者的区别 1 while while 是先检测退出条件,再执行循环体内的代码,即如果不满足条件,一次也不会执行...let i = 1 while (i <= 10) { console.log(i) } i小于等于10,条件永远是true,所以这...
do/while 循环是 while 循环的变体。该循环会执行一次代码块,在检查条件是否为真之前,然后如果条件为真的话,就会重复这个循环。 语法 do { 需要执行的代码 } while (条件); 实例 下面的例子使用 do/while 循环。该循环至少会执行一次,即使条件是 false,隐藏代码块会在条件被测试前执行: ...
do语句1;while(条件表达式); 说明: 语句 1是 do-while 循环语句的循环体,它会先执行一次,如果满足条件,还会被重复执行。 格式2 代码语言:javascript 代码运行次数:0 运行 AI代码解释 do{语句1;}while(条件表达式); 说明:循环体部分由多个语句构成,应由一对花括号括起来,构成一个语句块的形式。
