I want the table to be searched only in the H3 tag, not TD tag. And if a result is found, its TR should be hidden -h3 is a Child tag under TD.
for Example:
<tr>
<td>
<h3>Hier</h3>
<div></div>
</td>
</tr>
<script>
$(document).ready(function(){
$("#myInput").on("keyup", function() {
const value = $(this).val().toLowerCase();
$("#myTable tr").filter(function() {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});
console.log(value);
});
});
</script>
Thank you For Help
The main issue in your code is because you're searching through the text of the tr
as a whole. You need to call find('h3')
and then compare to the text in that element.
Also note that filter()
is intended to do just that; filter a collection of elements and return a subset of them. You shouldn't call toggle()
within it. Instead call hide()
, filter to find matches, then show()
them.
jQuery($ => { $("#search").on('input', e => { const value = $(e.target).val().toLowerCase().trim(); $("table tr").hide() .filter((i, tr) => $(tr).find('h3').text().toLowerCase().indexOf(value) > -1).show(); }); });
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <input type="text" name="search" id="search" /> <table> <tr> <td> <h3>Foo</h3> <div></div> </td> </tr> <tr> <td> <h3>Foo bar</h3> <div></div> </td> </tr> <tr> <td> <h3>Hier</h3> <div></div> </td> </tr> </table>
