Question

我目前正在为客户开发一个登陆页面网站，以展示一系列产品。

我已经在JS中创建了一个过滤器来过滤某些产品，但无法正常工作。

两个收音机都标记有Motorola，当您选择Motorola时，它们不会显示出来吗？

我将不胜感激某人能给我的帮助。

我对javascript并不是最有信心

<script>

$(':input').change(function(evt){

var filter = $(':input:checked,select').map(function(index, el) {
    return "." + el.value;
}).toArray().join("");

$(".product").hide().filter(filter).show();

});

</script>

Answer 1

代码存在的问题是您要隐藏public class MeetingAuthorizationHandler : AuthorizationHandler<SameCreatorRequirement> { protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, SameCreatorRequirement requirement) { context.Succeed(requirement); return Task.CompletedTask; } }，但是要隐藏的实际项目是.product。参见下面的工作演示。

.category

$(':input').change(function(evt) {
  var filter = $(':input:checked, select').map(function(_, el) {
    return "." + el.value;
  }).toArray().join("");

  $(".category").hide().filter(filter).show();
});

JS过滤器不起作用
