我正在使用jquery进行简单的图像过滤项目我有一个名为"数据类型"的数据属性，它包含多个值
例如：数据类型="科幻、警察、神秘、心理">
当我的数据类型有一个值时，比如data type="action"，我可以过滤包含动作类型的图像(通过在选择框中选择动作类型(但正如你所知，一部动漫可以有多种类型，所以当我像上面的例子一样添加多个值时，它什么都不显示。我想要我的jquery代码，这样当我在选择框中选择警察类型时，它应该循环通过数据类型的多个值，并用警察类型显示图像
这是我的源代码

试试这个代码，在选择框中选择一种类型，它不会显示任何图像
我想要这样一种解决方案，它应该适合我的代码(而不改变整个代码(，并解释它是如何工作的。
您需要将数据流派属性拆分到一个数组中，并检查所选流派是否存在于该数组中。
if (caGenre !== "all") {
var genreArray = $(this).attr('data-genre').split(",").map(function (item) { return item.trim(); })
okcaGenre = genreArray.indexOf(caGenre) !== -1;
}
正如您所看到的，我已经将数据类型字符串拆分为一个数组，并删除了每个项的周围空格。
更新的代码：
function updateCategories() {
//get all the values
var caType = $('select.type').val() || 'all';
var caGenre = $('select.genre').val() || 'all';
var caYear = $('select.year').val() || 'all';
var caSeason = $('select.season').val() || 'all';
var caStatus = $('select.status').val() || 'all';
$('.ps-page')
.find('.ps-links')
.hide()
.filter(function () {
var okcaType = true;
if (caType !== "all") {
okcaType = $(this).attr('data-type') === caType;
}
var okcaGenre = true;
if (caGenre !== "all") {
var genreArray = $(this).attr('data-genre').split(",").map(function (item) { return item.trim(); })
okcaGenre = genreArray.indexOf(caGenre) !== -1;
}
var okcaYear = true;
if (caYear !== "all") {
okcaYear = $(this).filter('data-year') === caYear;
}
var okcaSeason = true;
if (caSeason !== "all") {
okcaSeason = $(this).attr('data-season') === caSeason;
}
var okcaStatus = true;
if (caStatus !== "all") {
okcaStatus = $(this).attr('data-status') === caStatus;
}
//only fade a image if it satisfies all five conditions
return okcaType && okcaGenre && okcaYear && okcaSeason && okcaStatus;
}).fadeIn('fast');
}
