JavaScript 提示()命令

Question

我刚刚了解了prompt()命令；我知道 Prompt() 命令以字符串的形式返回用户输入。我正在搞乱下面的程序，我输入了Per“Dead”Ohlin作为男性名字。为什么这有效并且没有引起任何问题？ “Per“Dead”Ohlin...”应该引起了问题。解释器是否会通过在引号前添加转义字符来自动修复此问题？

let nameOfTheKiller = prompt("Type in a male name.");
let nameOfTheVictim = prompt("Type in a female name.");
let nameOfDrug = prompt("Type in the name of a drug.");
let nameOfAlchoholicBeverage = prompt("Type in the name of an alchoholic beverage.");
let story = nameOfTheKiller   
story += " went to a diner, met " 
story += nameOfTheVictim + ", and asked her to hangout."  
story += " She said yes, so " + nameOfTheKiller + " took her home. As soon as they arrived to " 
story += nameOfTheKiller + " relax-location, " + nameOfTheKiller 
story += " pulled out " + nameOfDrug + " and " + nameOfAlchoholicBeverage + ". " 
story += nameOfTheKiller + " and " + nameOfTheVictim 
story += " started using the party favors and got really high and drunk. The party favors gave " 
story += nameOfTheKiller + " auditory halucinations that comanded him to kill " 
story += nameOfTheVictim + ", so he did." ;


alert("We are done asking you questions. We are generating a story for you. The story will be finished, shortly.");
document.write(story) ;

Answer 1

prompt 不是 eval - 您传递给它的任何内容都将被解释为字符串。输入

Per "Dead" Ohlin

当这条线运行时

let nameOfTheKiller = prompt("Type in a male name.");

就像在做

let nameOfTheKiller = `Per "Dead" Ohlin`;

您输入的字符串中包含的任何恰好也是 Javascript 中有效字符串分隔符的字符将被解释为那些文字字符 (", ' ，反引号)，而不是作为分隔符。
