This article introduces how to implement a table data search feature.
HTML code:
<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search...">
<table id="myTable">
<tr class="header">
<th style="width:60%;">Name</th>
<th style="width:40%;">City</th>
</tr>
<tr>
<td>Alfreds Futterkiste</td>
<td>Germany</td>
</tr>
<tr>
<td>Berglunds snabbkop</td>
<td>Sweden</td>
</tr>
<tr>
<td>Island Trading</td>
<td>UK</td>
</tr>
<tr>
<td>Koniglich Essen</td>
<td>Germany</td>
</tr>
</table>
CSS code:
#myInput {
background-image: url('https://static.jyshare.com/images/mix/searchicon.png'); /*Search button*/
background-position: 10px 12px; /*Position the search button*/
background-repeat: no-repeat; /*No-repeat image*/
width: 100%;
font-size: 16px;
padding: 12px 20px 12px 40px;
border: 1px solid #ddd;
margin-bottom: 12px;
}
#myTable {
border-collapse: collapse;
width: 100%;
border: 1px solid #ddd;
font-size: 18px;
}
#myTable th, #myTable td {
text-align: left;
padding: 12px;
}
#myTable tr {
/*Add border to the table*/
border-bottom: 1px solid #ddd;
}
#myTable tr.header, #myTable tr:hover {
/*Add background to the table header and rows on mouse hover*/
background-color: #f1f1f1;
}
JavaScript code:
function myFunction() {
//Declare variables
var input, filter, table, tr, td, i;
input = document.getElementById("myInput");
filter = input.value.toUpperCase();
table = document.getElementById("myTable");
tr = table.getElementsByTagName("tr");
//Loop through each table row and find matches
for (i = 0; i < tr.length; i++) {
td = tr[i].getElementsByTagName("td")[0];
if (td) {
if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
tr[i].style.display = "";
} else {
tr[i].style.display = "none";
}
}
}
}
Tip:If you need case-sensitive matching, you can remove the toUpperCase() method.
Tip:If you need to search the second column (City), you can change tr[i].getElementsByTagName('td')[0]to[1]The index value starts from 0; i.e., 0 is the first column, 1 is the second column, and so on.
