如何获取作为参数传递给javascript中的函数的句子和单词的数组？

Question

我有一个函数说

var init = function(data){ 
    all sentences: " I have to get all the sentences and return an array containing all sentences" 
    all words : "this method should return an array of words in ‘Data’ when there is no parameter passed in. Optionally, when there is a parameter passed in that is a number, return the words in the sentence indicated by the input parameter" 

    all reverse sentences: "this method is the same as all Sentences, except it should return the sentences in reverse order" 

    reverse words :" same as all words but in reverse order" 
    countWordsBeginningWith:" this method should return the amount of words that begin with an inputted string. The optional second parameter should determine what sentence the words come from when present." 

感谢

我认为你需要做的是分解你的argument（假设它是一个字符串）到array。例如：

function getAllWords(sentences) { 
    var result = sentences.split(' '); 
    return result; 
} 

var init = function(data){ 
    var result = []; 
    result['words'] = getAllWords(data.text); 
    // result['sentences'] = getAllSentences(data.text); 
    // result['sentencesreversed'] = getReverseSentences(data.text); 
    // result['sentencewords'] = getReverseWords(data.text); 
    // result['beginswith'] = getWordsBeginningWith(data.text, data.beginswith); 
    return result; 
} 

var getIt = { 
    'beginswith': 't', 
    'text': 'This is stuff. I am a sentence. Stuff happens now.' 
}; 

console.log(init(getIt)); 

这是一个非常简单的答案，没有考虑周期，逗号和其他位。但这是一般的答案。有些for loops和/或RegEx可能发生在这一点之后，买家要小心。

在Javascript中你可以通过任何数据结构作为函数参数。

首先学习如何构造一个字符串数组来包含你的单词或句子。一旦你完成了这个，它将是直截了当的。
