我们的简易编译器完成了一大部分,但还有一些关键的语法结构没有处理,那就是for, while, do..while等循环语句对应的中间代码还没有生成,本节我们就针对这些语法结构进行相应的中间代码生成。 首先我们要了解循环语句对应的语法表达式: 代码语言:javascript
JS:设置超时时,do-while循环在函数上无限循环 我需要一个提示窗口,让用户输入一个数字。当设置一次函数(下面的代码)时,一切都可以,但这个提示窗口应该累积,直到一个整数(从200开始)的变量达到0,所以我认为do-while循环就可以了。但是,当设置do while循环时,输入数字后会立即显示提示窗口,并且不会更改任何内容。我...
While循环不循环(Javascript) 您需要首先定义输入,我会将列表放在while循环之外,因为如果不这样做,列表每次都会被覆盖。 let input = ''const list = [];while (input.toLowerCase() !== 'quit') { input = prompt('What do you want to do?') if (input === 'new') { let todo = prompt('What...
