Filter table from <select> input using jQuery

Question

I'm trying to filter a table from an alphabetical

<select>

input with jQuery.

I have first and last names in two columns of the table, and I'd like to filter the rows by either of these.

I have a select input set up as so:

<select>

    <option value="A">A</option>

    <option value="B">B</option>

    <option value="C">C</option>

    ...

</select>

and I'd like to filter this table:

<tr>

    <td>Joe</td>

    <td>Schmoe</td>

    <td>$2482.79</td>

    <td>172.78.200.124</td>

    <td>http://gmail.com</td>

</tr>

<tr>

    <td>John</td>

    <td>Doe</td>

    <td>$2776.09</td>

    <td>119.232.182.142</td>

    <td>http://www.example.com</td>

</tr>

How would I go about filtering the table using jQuery?

Answer 1

This will work assuming you only have one select and one table that is stuctured like your example

$(document).ready(function($) {
    var rows = $('table tr').each(function() {
    	var row = $(this);
    	var columns = row.children('td');

    	row.data('name-chars', [
    		columns.eq(0).html()[0].toUpperCase(),
    		columns.eq(1).html()[0].toUpperCase(),
    	]);
    });

    $('select').change(function() {
    	var char = $(this).val().toUpperCase();

    	rows.each(function() {
    		var row = $(this);
    		var chars_to_match = row.data('name-chars');
    		if($.inArray(char, chars_to_match) > -1) {
    			row.show();
    		}
    		else {
    			row.hide();
    		}
    	});
    });
});
