我得到了这些面板,这些面板具有按Red,Green和Yellow类进行过滤的选项,以及另一个Show All选项。他们的行为还可以,但是我想要实现的是:单击“全部显示”,然后单击例如“黄色”->,它应该隐藏除黄色以外的所有内容。另外,您应该只能选择“黄色+绿色”,“红色+黄色”等,以便只有那些按钮才保持选中状态。当用户单击所有三个按钮时,它可以自动选择“显示全部” ...
我对如何设置逻辑感到困惑,因此非常感谢任何帮助!
这是一支带有示例的笔:https://codepen.io/anon/pen/YOgqRX
$('.main__container').masonry({
itemSelector: '.item',
columnWidth: '.item'
});
$("#filter-show-all").on('click', function() {
$(".item").each(function(item) {
$(this).removeClass("panel-hide");
$('.main__container').masonry();
});
});
$("#filter-red").on('click', function() {
$(".red").toggleClass("panel-hide");
$('.main__container').masonry();
});
$("#filter-green").on('click', function() {
$(".green").toggleClass("panel-hide");
$('.main__container').masonry();
});
$("#filter-yellow").on('click', function() {
$(".yellow").toggleClass("panel-hide");
$('.main__container').masonry();
});

使用此jquery,如果它不起作用,请告诉我
$('.main__container').masonry({
itemSelector: '.item',
columnWidth: '.item'
});
$("#filter-show-all").on('click', function() {
$(this).toggleClass("selected");
if($(this).hasClass("selected"))
{
$(".item").each(function(item) {
$(this).toggleClass("panel-hide");
$('.main__container').masonry();
});
}
else{
$(".item").each(function(item) {
$(this).toggleClass("panel-hide");
$('.main__container').masonry();
});
}
});
$("#filter-red").on('click', function() {
$(this).toggleClass("selected");
if($(this).hasClass("selected"))
{
$(".red").removeClass("panel-hide");
}
else
{
$(".red").addClass("panel-hide");
}
if($('#filter-red').hasClass("selected") && $('#filter-green').hasClass("selected")&& $('#filter-yellow').hasClass("selected"))
{
$($('#filter-show-all').addClass("selected"))
}
else
{
$($('#filter-show-all').removeClass("selected"))
}
$('.main__container').masonry();
});
$("#filter-green").on('click', function() {
$(this).toggleClass("selected");
if($(this).hasClass("selected"))
{
$(".green").removeClass("panel-hide");
}
else
{
$(".green").addClass("panel-hide");
}
if($('#filter-red').hasClass("selected") && $('#filter-green').hasClass("selected")&& $('#filter-yellow').hasClass("selected"))
{
$($('#filter-show-all').addClass("selected"))
}
else
{
$($('#filter-show-all').removeClass("selected"))
}
$('.main__container').masonry();
});
$("#filter-yellow").on('click', function() {
$(this).toggleClass("selected");
if($(this).hasClass("selected"))
{
$(".yellow").removeClass("panel-hide");
}
else
{
$(".yellow").addClass("panel-hide");

$('.main__container').masonry();
