javascript - js直播搜索模式
问题描述
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”。有人可以帮我制作这个搜索模式吗?
解决方案
我希望这可以帮助你!
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";
}
}
}
