使用javascript创建虚拟文本

Question

我想使用javascript创建包含1000个单词的虚拟文本。我的想法是使用这样的数组

var words =["The sky", "above", "the port","was", "the color of television", "tuned", "to", "a dead channel", ".", "All", "this happened", "more or less","." ,"I", "had", "the story", "bit by bit", "from various people", "and", "as generally", "happens", "in such cases", "each time", "it", "was", "a different story","." ,"It", "was", "a pleasure", "to", "burn"]; 

然后使用javascript输出1000个字随机。我将如何使用JavaScript？任何其他方式来做到这一点？

Answer 1

这将需要以随机的顺序所有你的话：

function shuffle(array) { 
 
    var currentIndex = array.length, temporaryValue, randomIndex ; 
 

 
    // While there remain elements to shuffle... 
 
    while (0 !== currentIndex) { 
 

 
    // Pick a remaining element... 
 
    randomIndex = Math.floor(Math.random() * currentIndex); 
 
    currentIndex -= 1; 
 

 
    // And swap it with the current element. 
 
    temporaryValue = array[currentIndex]; 
 
    array[currentIndex] = array[randomIndex]; 
 
    array[randomIndex] = temporaryValue; 
 
    } 
 

 
    return array; 
 
} 
 

 
var words =["The sky", "above", "the port","was", "the color of television", "tuned", "to", "a dead channel", ".", "All", "this happened", "more or less","." ,"I", "had", "the story", "bit by bit", "from various people", "and", "as generally", "happens", "in such cases", "each time", "it", "was", "a different story","." ,"It", "was", "a pleasure", "to", "burn"]; 
 

 
shuffle(words); 
 
var sentence = words.join(" ") 
 

 
// Demo 
 
console.log(words); 
 
console.log(sentence); 
 
document.write(sentence)

使用shuffle()从How to randomize (shuffle) a JavaScript array?

Answer 2

看看这个

var words =["The sky", "above", "the port","was", "the color of television", "tuned", "to", "a dead channel", ".", "All", "this happened", "more or less","." ,"I", "had", "the story", "bit by bit", "from various people", "and", "as generally", "happens", "in such cases", "each time", "it", "was", "a different story","." ,"It", "was", "a pleasure", "to", "burn"]; 
 
var text = []; 
 
var x = 1000; 
 
while(--x) text.push(words[Math.floor(Math.random() * words.length)]); 
 
document.write(text.join(" "))

Answer 3

var m = words.length, 
    t, i,result=[]; 
while (m && result.length < 100) { 
    i = Math.floor(Math.random() * m--); 
    t = arr[m]; 
    arr[m] = arr[i]; 
    arr[i] = t; 
    result.push(arr[m]); 
}

至于我个人喜欢Lorem存有，这个怎么样？

var r = new XMLHttpRequest(); 
r.onload = function() { 
    if (r.readyState != 4 || r.status != 200) return; // bad query or something... 
    document.getElementById('LIpsum').textContent = r.responseText; 
}; 
r.open('GET', 'https://baconipsum.com/api/?type=meat-and-filler&paras=18&format=text'); 
r.send();

Answer 5

var words = ["The sky", "above", "the port", "was", "the color of television", "tuned", "to", "a dead channel", ".", "All", "this happened", "more or less", ".", "I", "had", "the story", "bit by bit", "from various people", "and", "as generally", "happens", "in such cases", "each time", "it", "was", "a different story", ".", "It", "was", "a pleasure", "to", "burn"]; 
 

 
function randomSentence() { 
 
    var n = 1000; 
 
    var sentence = ""; 
 
    while (n--) { 
 
    sentence += words[Math.floor(Math.random() * words.length)] + " "; 
 
    } 
 
    return sentence; 
 
} 
 
document.writeln(randomSentence())

我分开标点符号和大小写和算的话，而不是数组中使用的项目。这里的一个的jsfiddle：

下面的代码：

var words =["the sky", "above", "the port","was", "the color of television", "tuned", "to", "a dead channel", "all", "this happened", "more or less" ,"I", "had", "the story", "bit by bit", "from various people", "and", "as generally", "happens", "in such cases", "each time", "it", "was", "a different story", "it", "was", "a pleasure", "to", "burn"], 
    punctuation = [".", ","], 
    text = "", 
    phrase, 
    punc, 
    count = 0, 
    nextCapital = true; 
while(count<1000) { 
    phrase = words[Math.floor(Math.random() * words.length)] 
    text += nextCapital ? phrase[0].toUpperCase() + phrase.slice(1): phrase; 
    nextCapital = false; 
    if (Math.random() > .8) { 
    punc = punctuation[Math.floor(Math.random() * punctuation.length)]; 
    if (punc === ".") nextCapital = true; 
    text += punc; 
    } 
    text += " "; 
    count = text.match(/\S+/g).length; 
} 
document.write(text);
