Javascript随机赞美生成器 [英] Javascript Random Compliment Generator

问题描述

在JS中，我正在尝试使用Arrays创建一个随机的赞美生成器。目标是当程序运行时，它从每个数组中取一个随机部分，然后显示字符串。我确定我在这里使用了太多变量，但我很挣扎。

页面顶部的变量（whatList，descriptionList和betterthanList）是我得到的，剩下的就是我尝试解决它。



var whatList = [hair，face，figure，brain，音乐品味，Javascript代码编写能力] ;

var descriptionList = [漂亮，聪明，美丽，精明，喜欢品尝彩虹];

var betterthanList = [在阿尔加维两个人的周末，Nooblab的金牌，保罗·内维的秃头，在学生会的地铁中吃了一顿饭，


var random1 = Math.random（）* 7;

var randoma = Math.floor（random1）;



var random2 = Math.random（）* 6;

var randomb = Math.floor（random2）;



var random3 =数学。 random（）* 5;

var randomc = Math.floor（random3）;



var whatChoice1;

var whatChoice2;

var whatChoice3;

var whatChoice4;

var whatChoice5;

var whatChoice6;



var desChoice1;

var desChoice2;

var desChoice3;

var d esChoice4;

var desChoice5;



var betterChoice1;

var betterChoice2;

var betterChoice3;

var betterChoice4;



if（randoma = 0）



{

whatChoice1 = whatList [0];

}

else if（randoma = 1）

{

whatChoice2 = whatList [1];

}

else if（randoma = 2）

{

whatChoice3 = whatList [2];

}

else if（randoma = 3）

{

whatChoice4 = whatList [3];

}

否则if（randoma = 4）

{

whatChoice5 = whatList [4];

}

else if（randoma = 5）

{

whatChoice6 = whatList [5];

}



if（randomb = 0）

{

desChoice1 = descriptionList [0];

}

else if（randomb = 1）

{

desChoice2 = descriptionList [1];

}

else if（randomb = 2）

{

desChoice3 = descriptionList [2];

}

else if（randomb = 3）

{

desChoice4 = descriptionList [3];

}

else if（randomb = 4）

{

desChoice5 = descriptionList [4];

}



if（randomc = 0）

{

betterChoice1 = betterthanList [0];

}

else if（randomc = 1）

{

betterChoice2 = betterthanList [1];

}

else if（randomc = 2）

{

betterChoice3 = betterthanList [2];

}

否则（randomc = 3）

{

betterChoice4 = betterthanList [3];

}



console.log（你的+ whatChoice [] +是+ desChoice [] +并且优于+ betterChoice []）;

解决方案

为什么不直接使用变量？ if语句不是必需的。



您可能只想检查randoma / randomb的范围是否在数组的下边界和上边界：

 whatChoice3 = whatList [randoma]; 
 desChoice2 = descriptionList [randomb]; 

祝你好运！

你不需要if链：你有数组！

例如 whatList 中的选择可以用这种方式编码：

  var  rwl = Math.floor（（Math.random（）* 6））;  //  生成介于0..5（包含）之间的随机数 
  var  whatChoice = whatList [rwl];  //  使用随机数索引数组。 
 

In JS, I''m trying to make a random compliment generator using Arrays. The goal is that when the program is run, it takes a random part from each array and then displays the string. I''m sure i''ve used far too many variables here, but I am struggling.
The variables at the top of the page (whatList, descriptionList, and betterthanList) are what i''ve been given, and the rest is my attempt to solve it.

var whatList = ["hair", "face", "figure", "brain", "taste in music", "ability to code in Javascript"];
var descriptionList = ["pretty", "intelligent", "beautiful", "astute", "like tasting a rainbow"];
var betterthanList = ["a weekend for two in the Algarve", "a gold medal on Nooblab", "the baldness of Paul Neve", "a slap up meal in Subway in the student union"];

var random1 = Math.random()*7;
var randoma = Math.floor(random1);

var random2 = Math.random()*6;
var randomb = Math.floor(random2);

var random3 = Math.random()*5;
var randomc = Math.floor(random3);

var whatChoice1;
var whatChoice2;
var whatChoice3;
var whatChoice4;
var whatChoice5;
var whatChoice6;

var desChoice1;
var desChoice2;
var desChoice3;
var desChoice4;
var desChoice5;

var betterChoice1;
var betterChoice2;
var betterChoice3;
var betterChoice4;

if(randoma = 0)

{
whatChoice1 = whatList[0];
}
else if (randoma = 1)
{
whatChoice2 = whatList[1];
}
else if(randoma = 2)
{
whatChoice3 = whatList[2];
}
else if(randoma = 3)
{
whatChoice4 = whatList[3];
}
else if(randoma = 4)
{
whatChoice5 = whatList[4];
}
else if(randoma = 5)
{
whatChoice6 = whatList[5];
}

if (randomb = 0)
{
desChoice1 = descriptionList[0];
}
else if (randomb = 1)
{
desChoice2 = descriptionList[1];
}
else if(randomb = 2)
{
desChoice3 = descriptionList[2];
}
else if(randomb = 3)
{
desChoice4 = descriptionList[3];
}
else if(randomb = 4)
{
desChoice5 = descriptionList[4];
}

if(randomc = 0)
{
betterChoice1 = betterthanList[0];
}
else if (randomc = 1)
{
betterChoice2 = betterthanList[1];
}
else if(randomc = 2)
{
betterChoice3 = betterthanList[2];
}
else if(randomc = 3)
{
betterChoice4 = betterthanList[3];
}

console.log("Your " + whatChoice[] + " is" + desChoice[] + " and better than" + betterChoice[]);

解决方案

Why not use the variables directly? The if statements aren''t necessary.

You might just want to check if the range of randoma/randomb is in the lower and upper boundary of the array:

whatChoice3 = whatList[randoma];
desChoice2 = descriptionList[randomb];

Good luck!

You don''t need the if chains: you have arrays!
For instance the choiche in whatList could be coded this way:

var rwl = Math.floor((Math.random()*6)); // generate a random number between 0..5 (included)
var whatChoice = whatList[rwl]; // use the random number to index the array.
