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 我正在使用带有html css和js的实时搜索 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东西。 例如，当有人搜索"四个名称"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？

我希望这对您有所帮助！

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 {
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 {

list-style-type: none;

#myUL li a {

}
#myUL li a:hover:not(.header) {

}

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