Question

var words = [
    {word: 'cow', explain: 'animal'},
    {word: 'apple', explain: 'fruit'},
    {word: 'dog', explain: 'animal'}];
var word2 = ["cow", "dog"];

如何将单词与 word2 进行比较，并使用Jquery为匹配的单词 red 着色？

我的问题在于对象，我无法提取 word

中的元素你能帮帮我吗？谢谢

Answer 1

对于问题的第一部分，您可以使用Array.filter()：

var words = [
    {word: 'cow', explain: 'animal'},
    {word: 'apple', explain: 'fruit'},
    {word: 'dog', explain: 'animal'}
];
var word2 = ["cow", "dog"];

var wordsInWord2 = words.filter(function (obj) {
    return word2.indexOf(obj.word) !== -1;
});

假设您的Javascript在网络浏览器中运行，问题的第二部分将需要HTML，因为Javascript并没有直接输出彩色文字的方法。

Answer 2

尝试类似

的内容

words.filter( function(e,i,arr){
  return word2.filter(e2 => e.word === e2).length; // only keep the words form word2
}).forEach( function(e,i,arr){
  /*do something where e is of the form {word: ..., explain: ...} */
});

Answer 3

var words = [
    {word: 'cow', explain: 'animal'},
    {word: 'apple', explain: 'fruit'},
    {word: 'dog', explain: 'animal'}];
var word2 = ["cow", "dog"];

var result = [];
words.forEach(function(e){
    if(word2.indexOf(e.word) != -1)
        result.push(e);
});

console.log(result);

Answer 4

这很简单......但你需要先将单词转换为对象

var words = {
  "cow": { "explain": "animal" },
  "apple": { "explain": "fruit" },
  "dog": { "explain": "animal" }
};

然后

for (var i = 0; i < words2.length; i++)
{
    if (words[words2[i]])
    {
        // found a math at index i
    }
}

从对象获取元素并与Array - Jquery进行比较
