我正在使用同位素对产品页面进行排序，过滤和搜索。到现在为止还挺好。我被困在两个领域。我无法在网上找到具有我所需功能的确切组合的示例，因此需要一些帮助。
简而言之，我有多个选择下拉列表过滤产品，选择价格排序顺序和快速搜索输入字段。所有工作，但我需要一些修改。
去做：
过滤后搜索不起作用。我需要它来使用过滤器。
在价格选择下拉菜单中增加了按“销售”和“新入”分类。
URL哈希侦听器的添加，以创建用于过滤的链接，即，链接到“新入站”（首先排序）。
我当前用于过滤和排序的JS：
$(document).ready(function(){
// quick search regex
var qsRegex;
var filterValue;
// init Isotope
var $grid = $(".grid").isotope({
itemSelector: ".grid-item",
layoutMode: "fitRows",
getSortData: {
price: '.t-price parseInt',
category: '[data-category]',
},
filter: function() {
var $this = $(this);
var searchResult = qsRegex ? $this.text().match(qsRegex) : true;
var selectResult = filterValue ? $this.is(filterValue) : true;
return searchResult && selectResult;
}
});
// bind filter on select change
//$(".filter-select").on("change", function() {
// get filter value from option value
// filterValue = $(this).val();
//console.log(filterValue);
//$grid.isotope();
//});
// store filter for each group
var filters = {};
$('.filter-select').on( 'change', function( event ) {
var $select = $( event.target );
// get group key
var filterGroup = $select.attr('value-group');
// set filter for group
filters[ filterGroup ] = event.target.value;
// combine filters
var filterValue = concatValues( filters );
// set filter for Isotope
$grid.isotope({ filter: filterValue });
});
// flatten object by concatting values
function concatValues( obj ) {
var value = '';
for ( var prop in obj ) {
value += obj[ prop ];
}
return value;
}
$('#price-sort').on( 'change', function() {
var type = $(this).find(':selected').attr('data-sorttype');
console.log(type);
var sortValue = this.value;
if(type=='ass'){$grid.isotope({ sortBy: sortValue , sortAscending: false});}
else{$grid.isotope({ sortBy: sortValue , sortAscending: true});}
$grid.isotope({ sortBy: sortValue });
});
// change is-checked class on buttons
$('#price-sort').on( 'change', function() {
var sortByValue = this.value;
console.log(sortByValue);
$grid.isotope({ sortBy: sortByValue});
});
// use value of search field to filter
var $quicksearch = $(".quicksearch").keyup(
debounce(function() {
qsRegex = new RegExp($quicksearch.val(), "gi");
$grid.isotope();
})
);
// debounce so filtering doesn't happen every millisecond
function debounce(fn, threshold) {
var timeout;
return function debounced() {
if (timeout) {
clearTimeout(timeout);

请注意，这是两个部分的答案。从其他答案中检查第2部分。
当我阅读您的代码时，您就走对了。由于搜索和过滤器在代码中无法同时工作的原因，问题在于，当初始化$ grid时，您为$ grid定义了过滤器功能。然而，当与选择滤波器组的改变，可以通过调用$ grid.isotope（{：filterValue过滤器}）重新定义该过滤器。当您使用任何可配置的值调用$ grid.isotope（）时，$ grid将采用这些新配置。
因此，您问题的答案仅是具有两个变量。一种用于存储过滤器值，另一种用于存储搜索值。每当调用$ grid.isotope（）时，它将仅使用这两个值进行过滤。
您的代码还有另外几个问题。您无需进行两次价格分类。那只需要做一个。当涉及到HTML，类和ID时，ID仅应在页面中出现一个。这就是说，您不能将两个具有相同ID的除法运算。如果不重要，它可能不会破坏您的页面。但是，在以编程方式操作页面时，这可能会破坏页面。除此之外，您使用filter-select的方式还意味着从两个按钮组中获取值。但这可能适用于您的情况，我想您将来可能会需要除大小以外的颜色，颜色等等。此外，在比较JS中的字符串作为价格排序时。最好将带有===的字符串进行比较以确保相等。要比较JS中的字符串，可以参考JavaScript比较中应使用哪个等于运算符（== vs ===）？。
对于代码设计，您可以那样做。我认为将此类内容放入document.ready（）的方式将使代码运行更快。
对于答案代码，例程很简单。准备好文档后，将初始化与搜索字段和选择字段关联的所有事件。之后，将filterWithHash（）函数绑定到onhashchange事件。然后执行该函数以初始化网格，同时检查URL的任何关联哈希。
对于URL中的哈希，请尝试“ filter =“和“ search =”。它们可以一起使用而没有任何问题。您还可以将该函数转换为不仅可以接受哈希而且可以接受get参数。
代码中还有一些注释可能会帮助您。

</html>我限制为30000个字符。因此，我从示例2中删除了HTML部分。只需将示例1的JS替换为示例2中的JS，即可运行示例2。
对于第二个示例，其例程几乎与第一个示例的例程相似。对于第二个示例，每当用户选择与网格的过滤操作关联的任何字段时，所选值就会应用于网格。之后，这些值将应用于location.hash。为了防止filterWithHash（）运行并解释刚刚创建的哈希。setHash（）函数将一个名为gridAlreadyUpdated的变量设置为true，以告诉filterWithHash（）不需要更新任何内容。
setHash（）函数将仅解释与过滤操作关联的哈希参数。其他哈希被忽略。
我在代码中编写的其他注释也可能会为您提供帮助。
