显示隐藏的表，直到单击搜索按钮

Question

I have a search box that makes a request within a table and displays the queried results.

I want the tables to remain hidden until the user starts the search.

HTML

<section class="container">


<input type="search" class="table-filter" data-table="order-table" placeholder="Filter" >

<table class="order-table table">

    <tbody>
        <tr>
            <td>John</td>
            <td>john.doe</td>
        </tr>
        <tr>
            <td>Jane Vanda</td>
            <td>jane@vanda</td>
        </tr>
        <tr>
            <td>Alferd Penyworth</td>
            <td>alfred</td>
        </tr>
    </tbody>
</table>

JS

(function(document) {
'use strict';

var TableFilter = (function(Arr) {

    var _input;

    function _onInputEvent(e) {
        _input = e.target;
        var tables = document.getElementsByClassName(_input.getAttribute('data-table'));
        Arr.forEach.call(tables, function(table) {
            Arr.forEach.call(table.tBodies, function(tbody) {
                Arr.forEach.call(tbody.rows, _filter);
            });
        });
    }

    function _filter(row) {
        var text = row.textContent.toLowerCase(), val = _input.value.toLowerCase();
        row.style.display = text.indexOf(val) === -1 ? 'none' : 'table-row';
    }

    return {
        init: function() {
            var inputs = document.getElementsByClassName('table-filter');
            Arr.forEach.call(inputs, function(input) {
                input.oninput = _onInputEvent;
            });
        }
    };
})(Array.prototype);

document.addEventListener('readystatechange', function() {
    if (document.readyState === 'complete') {
        TableFilter.init();
    }
});

})(document);

Try it.

(function(document) {
    'use strict';

    var TableFilter = (function(Arr) {

        var _input;

        function _onInputEvent(e) {
            _input = e.target;
            var tables = document.getElementsByClassName(_input.getAttribute('data-table'));
            Arr.forEach.call(tables, function(table) {
                /* New code here */
                table.style.display = _input.value.length > 0 ? 'table' : 'none'; // Or inline maybe.
                Arr.forEach.call(table.tBodies, function(tbody) {
                    Arr.forEach.call(tbody.rows, _filter);
                });
            });
        }

        function _filter(row) {
            var text = row.textContent.toLowerCase(), val = _input.value.toLowerCase();
            row.style.display = text.indexOf(val) === -1 ? 'none' : 'table-row';
        }

        return {
            init: function() {
                var inputs = document.getElementsByClassName('table-filter');
                Arr.forEach.call(inputs, function(input) {
                    /* New code here */
                    var tables = document.getElementsByClassName(input.getAttribute('data-table'));
                    Arr.forEach.call(tables, function(table) {
                        table.style.display = 'none';
                    });
                    /* */
                    input.oninput = _onInputEvent;
                });
            }
        };
    })(Array.prototype);

    document.addEventListener('readystatechange', function() {
        if (document.readyState === 'complete') {
            TableFilter.init();
        }
    });

})(document);
