我正试图通过一个带有过滤器的表格进行实时搜索。 当过滤器被应用时，我希望只搜索当前显示的行。 目前搜索和过滤器都是自己工作的。 我试过使用JQuery的visiblehidden选择器只在可见的行中迭代，但这不起作用，因为被隐藏的行在进一步搜索时不会变得可见。 如何让它们一起工作？ JSfiddle。https:/jsfiddle.netL09u3z4p

$(document).ready(function () {
// Live search function through user input
$("#search").keyup(function () {
var value = $(this).val().toLowerCase().trim();
// Tried searching through visible rows - does not work - ex $("#indexTable tbody tr").not(":hidden").each...
$("#indexTable tbody tr").each(function (index) {
var row = $(this);
var name = row.find('td').eq(0).text().toLowerCase().trim();
var location = row.find('td').eq(1).text().toLowerCase().trim();
if (name.indexOf(value) == -1 && location.indexOf(value) == -1) {
row.hide();
}
else {
row.show();
}
});
});
// Map regions to cities
const regions = {
'central': ['Chicago', 'Madison', 'Dallas'],
'east': ['New York', 'Boston'],
'west': ['Seattle', 'Los Angeles'],
}
// Table filters through checkboxes
$("input[type='checkbox']").change(function () {
var locations = [];
var hideNoAges = $('#hideAge').is(":checked")
// Get ids of each region checkbox checked
$(".location:input[type='checkbox']").each(function () {
if ($(this).is(":checked")) {
locations.push($(this).attr('id'));
}
})
// Get list of all cities to be included in filter
var cities = locations.map(function (i) {
return regions[i].join();
}).join().split(",");
if (cities == "" && !hideNoAges) { // if no filters selected, show all items
$("#indexTable tbody tr").show();
} else { // otherwise, hide everything...
$("#indexTable tbody tr").hide();
$("#indexTable tbody tr").each(function () {
var show = false;
var row = $(this);
if (hideNoAges) {
if (row.find('td').eq(2).text() == "Unknown") {
show = false;
} else {
show = true;
if (cities != "") {
cities.forEach(function (city) {
if (row.find('td').eq(1).text() != city) {
show = false;
}
});
}
}
}
cities.forEach(function (city) {
if (row.find('td').eq(1).text() == city) {
show = true;
if (hideNoAges && row.find('td').eq(2).text() == "Unknown") {
show = false;
}
}

if (show) {
row.show();

你可以尝试为被过滤器应用的行添加一个类，然后用类选择器在这些行上进行搜索（比如说 .filtering). 反之亦然，你也可以用搜索来做（也许是 .searching)，并对其应用过滤器。
