使用JS和jQuery搜索HTML表

使用JS和jQuery搜索HTML表

Mil*_*ilo 7 html javascript jquery zurb-foundation

我做了一张桌子,想让它可以搜索,所以我用谷歌搜索并看了一下starckoverflow.
但不知何故,我发现的那些应该有用的东西对我不起作用？

这是HTML和JS的代码.

                    $("#table tbody tr").hide();
                    $("#table td:contains-ci('" + $(this).val() + "')").parent("tr").show();

我已经把你的代码部分重要了,并写了一个工作小提琴

http://jsfiddle.net/9hGym/602/

这是搜索引擎:

    var searchText = $(this).val().toLowerCase();
    $.each($("#table tbody tr"), function() {
        if($(this).text().toLowerCase().indexOf(searchText) === -1)
           $(this).hide();
        else
           $(this).show();                
    });

我发现上述解决方案从理论上讲是很好的（尽管它不起作用），但是我发现它可以更好地工作：

$('#search-field').on('keyup', function(e) {
    if ('' != this.value) {
        var reg = new RegExp(this.value, 'i'); // case-insesitive

        $('.table tbody').find('tr').each(function() {
            var $me = $(this);
            if (!$me.children('td:first').text().match(reg)) {
                $me.hide();
            } else {
                $me.show();
            }
        });
    } else {
        $('.table tbody').find('tr').show();
    }
});

如果要搜索多个列，则只需更改：

if (!$me.children('td:first').text().match(reg)) {

至：

if (!$me.children('td').text().match(reg)) {
