我是一个自学的程序员，我目前正在工作的职位列表网站项目。我有一个有搜索功能的职位列表页面。现在，用户可以通过职位名称进行搜索，我想添加按关键字进行搜索的选项。

每个职务有6个属性:职务名称、工作地点、工作类型、职业行业和工作关键词.作业关键字是一个列表，因为作业可以有不同数量的关键字。

<div class="job-listing">
    <div class="container">
            <div class="job-number">
                <h2>We Found <span id="number-jobs-total" class="text-secondary">214</span> Offers For <span>You</span> </h2>

            <nav class="pagination-container">
                <ul class="pagination">
                    <li><a href="javascript:void(0)">Previous</a></li>
                    <li><a href="javascript:void(0)">Next</a></li>

                </ul>
            </nav>
    </div>
</div>

JS用于按标题搜索：

const search= document.querySelector(".skills");
const jobs = Array.from(document.querySelector(".job-board").children);

const filterJobs = term => {
    jobs.filter(job =>{
        const title = job.querySelector(".job-title").textContent.toLowerCase();

        if(title.includes(term.toLowerCase()) || totalKeywords.includes(term.toLowerCase()) ){
            job.style.display = "list-item";
        } else{
            job.style.display = "none";
        }
    });
};

search.addEventListener("keyup", e =>{
    filterJobs(e.currentTarget.value.trim());
});

JS:我已经尝试过了，我认为我不是很远，但仍然没有在工作。

const search= document.querySelector(".skills");
const jobs = Array.from(document.querySelector(".job-board").children);

const filterJobs = term => {
    jobs.filter(job =>{
        const title = job.querySelector(".job-title").textContent.toLowerCase();
        const keyword = job.querySelectorAll(".job-keywords li");
        totalKeywords = [];
        for(var i = 0 ; i < keyword.length ; i++){
            totalKeywords.push(keyword[i].textContent);
        }
        console.log(totalKeywords);

        if(title.includes(term.toLowerCase()) || totalKeywords.includes(term.toLowerCase()) ){
            job.style.display = "list-item";
        } else{
            job.style.display = "none";
        }
    });
};

search.addEventListener("keyup", e =>{
    filterJobs(e.currentTarget.value.trim());
});

我认为您的代码的问题是关键字不是字符串，而是字符串数组，所以您需要做的是搜索关键字数组，即

 let inKeywords = totalKeywords.some(keyword => keyword.toLowerCase().includes(term.toLowerCase()));
 if(title.includes(term.toLowerCase()) || inKeywords ){
        job.style.display = "list-item";
    } else{
        job.style.display = "none";
    }

我建议你不要使用includes，而是更喜欢indexOf。您可以找到更多的信息，here

const search = document.querySelector('.skills');
const jobs = Array.from(document.querySelector('.job-board').children);

const filterJobs = term => {
  jobs.filter(job => {
    const title = job.querySelector('.job-title').textContent.toLowerCase();
    const keyword = job.querySelectorAll('.job-keywords li');
    const totalKeywords = [];
    for (var i = 0; i < keyword.length; i++) {
      totalKeywords.push(keyword[i].textContent);
    }
    console.log(totalKeywords);

    if (title.includes(term.toLowerCase()) || totalKeywords.indexOf(term.toLowerCase()) > -1) {
      job.style.display = 'list-item';
    } else {
      job.style.display = 'none';
    }
  });
};

search.addEventListener('keyup', e => {
  filterJobs(e.currentTarget.value.trim());
});

以下是这种前端过滤的一个很好的技巧。我不知道它是否是您想要的东西，因为这并不是OP所要求的，但是这将搜索您的所有字段(标题、位置、类型、日期、行业、关键字)：

    const search= document.querySelector(".skills");
    const jobs = Array.from(document.querySelector(".job-board").children);
    const filterJobs = term => {
        jobs.filter(job =>{
            jobText = job.textContent || job.innerText || ""; // strip html tags from the job element and keeps only text
            jobText = jobText.toLowerCase();
            if(jobText.indexOf(term.toLowerCase()) > -1){
                job.style.display = "list-item";
            }
            else{
                job.style.display = "none";
            }
        });
    };
    search.addEventListener("keyup", e =>{
        filterJobs(e.currentTarget.value.trim());
    });

<input type="text" class="skills" placeholder="search">

<div class="job-listing">
    <div class="container">
            <div class="job-number">
