javascript - Js 实时搜索模式

Question

function livesearch() {
    // Declare variables
    var input, filter, ul, li, a, i;
    input = document.getElementById('myInput');
    filter = input.value.toUpperCase();
    ul = document.getElementById("myUL");
    li = ul.getElementsByTagName('li');

    // Loop through all list items, and hide those who don't match the search query
    for (i = 0; i < li.length; i++) {
        a = li[i].getElementsByTagName("a")[0];
        if (a.innerHTML.toUpperCase().indexOf(filter) > -1) {
            li[i].style.display = "";
        } else {
            li[i].style.display = "none";
        }
    }
}

#myInput {
    background-image: url('/css/searchicon.png'); /* Add a search icon to input */
    background-position: 10px 12px; /* Position the search icon */
    background-repeat: no-repeat; /* Do not repeat the icon image */
    width: 100%; /* Full-width */
    font-size: 16px; /* Increase font-size */
    padding: 12px 20px 12px 40px; /* Add some padding */
    border: 1px solid #ddd; /* Add a grey border */
    margin-bottom: 12px; /* Add some space below the input */
}

#myUL {
    /* Remove default list styling */
    list-style-type: none;
    padding: 0;
    margin: 0;
}

#myUL li a {
    border: 1px solid #ddd; /* Add a border to all links */
    margin-top: -1px; /* Prevent double borders */
    background-color: #f6f6f6; /* Grey background color */
    padding: 12px; /* Add some padding */
    text-decoration: none; /* Remove default text underline */
    font-size: 18px; /* Increase the font-size */
    color: black; /* Add a black text color */
    display: block; /* Make it into a block element to fill the whole list */
}

#myUL li a:hover:not(.header) {
    background-color: #eee; /* Add a hover effect to all links, except for headers */
}

    <input type="text" id="myInput" onkeyup="livesearch()" placeholder="Search for names..">

    <ul id="myUL">
        <li><a href="#">name</a></li>
        <li><a href="#">two word</a></li>
        <li><a href="#">three words name</a></li>
        <li><a href="#">four words name example</a></li>
    </ul>

大家好我正在使用 html css 和 js 进行实时搜索当我搜索确切的模式时，一切都很好但我正在寻找显示不规则搜索的内容。比如当有人搜索“四个名字”或“单词示例”时，结果显示“四个单词名称示例”。谁能帮我制作这个搜索模式？

希望对你有帮助!

function livesearch() {
  // Declare variables
  var input, filter, ul, li, a, i;
  input = document.getElementById('myInput');
  filter = input.value.toUpperCase();
  filter = filter.split(' ');
  ul = document.getElementById("myUL");
  li = ul.getElementsByTagName('li');

  // Loop through all list items, and hide those who don't match the search query
  for (i = 0; i < li.length; i++) {
    var sw = 1;
    a = li[i].getElementsByTagName("a")[0];
    for (var jj = 0; jj < filter.length; jj++) {
      if (a.innerHTML.toUpperCase().indexOf(filter[jj]) == -1) {
        sw = 0;
        break;
      }
    }
    if (sw) {
      li[i].style.display = "";
    } else {
      li[i].style.display = "none";
    }
  }
}

#myInput {

  /* Add a search icon to input */
