我有合作的UI滑块和复选框过滤器的一个问题。它应该如下工作：

当我使用滑块来设置目标价我得到的一些结果。然后希望这些结果通过额外使用过滤器复选框进行排序。毕竟我应该得到精确匹配我的要求。

取而代之的是我得到错误的比赛。采用滑盖之后，我得到了我想要什么，但然后使用复选框一切美眉时。我只得到复选框结果，而滑盖效果。我不知道如何迫使他们一起工作。

我还希望看到有关发现结果的数量信息，如果只滑块已使用（不点击复选框）。

      d.initMouseEvent(b, !0, !0, window, 1, c.screenX, c.screenY, c.clientX, c.clientY, !1, !1, !1, !1, 0, null), a.target.dispatchEvent(d)

    var e, b = a.ui.mouse.prototype,

      var b = this;
      !e && b._mouseCapture(a.originalEvent.changedTouches[0]) && (e = !0, b._touchMoved = !1, f(a, "mouseover"), f(a, "mousemove"), f(a, "mousedown"))
    }, b._touchMove = function(a) {

    }, b._mouseInit = function() {
      var b = this;
      b.element.bind({

是任何人能解决这种情况？

尝试了这一点：

我重构你的代码很多，使其更易于阅读/理解并让事情干。我能够从273线降低线路数到73。

 $(document).ready(function(){ // cache ref to all checkbox elements var checkboxes = $('input:checkbox'), // cache ref to results results = $('#results'), // cache ref to our list listItems = $('.tabela > li'), // cache amount ref amount = $('#amount'), // collection of selected checkbox elements selectedItems = [], // slider config slideOptions = { min: 500, max: 100000, step: 500, values: [10000], slide: function(event, ui) { amount.val(ui.values[0] + " USD"); }, change: function(event, ui) { updateList(); } }; // render our slider var slider = $("#price").slider(slideOptions); amount.val($("#price").slider("values", 0) + " USD"); checkboxes.on('change', function(){ var id = this.id; if(this.checked){ // push the element vs the value selectedItems.push(this.value); }else{ // remove items on uncheck selectedItems.splice(selectedItems.indexOf(this.value), 1); } updateList(); }); var updateList = function(){ // create map of values for joining var selectedItemsValues = selectedItems.sort().join(' '), // min value minPrice = slider.slider('values', 0); // filter list items listItems.hide().filter(function(){ // get data attributes var data = this.dataset; // restrict list to price band and selections return Number(data.price) > minPrice && (selectedItems.length ? data.category.includes(selectedItemsValues) : true); }) .show(); // count visible li only var total = $('.tabela li:visible').length; if(total === 0){ results.html('We did not find any matches.'); }else{ results.html('We found ' + total + (total === 1 ?

Answer 2:

问题是，你添加和删除类slider1Hide显示/隐藏的物品运到滑块的范围，但使用内联样式display: list-item / display: none为复选框。内联CSS样式总是接管一个类定义的样式先例，所以即使你的项目之一具有slider1Hide ，它仍然会显示如果有display: list-item 。您可以使用浏览器的检查-你看到过一个线观察此display的属性slider1Hide ：

不管怎么说，解决你的问题我已经更新您的JavaScript。这两个函数filterPrice()和filterCheckboxes()走在产品列表中，并过滤掉应该保持隐藏的人。然后，代码show()的剩余产品。

!function(a){function f(a,b){if(!(a.originalEvent.touches.length>1)){a.preventDefault();var c=a.originalEvent.changedTouches[0],d=document.createEvent("MouseEvents");d.initMouseEvent(b,!0,!0,window,1,c.screenX,c.screenY,c.clientX,c.clientY,!1,!1,!1,!1,0,null),a.target.dispatchEvent(d)}}if(a.support.touch="ontouchend"in document,a.support.touch){var e,b=a.ui.mouse.prototype,c=b._mouseInit,d=b._mouseDestroy;b._touchStart=function(a){var b=this;!e&&b._mouseCapture(a.originalEvent.changedTouches[0])&&(e=!0,b._touchMoved=!1,f(a,"mouseover"),f(a,"mousemove"),f(a,"mousedown"))},b._touchMove=function(a){e&&(this._touchMoved=!0,f(a,"mousemove"))},b._touchEnd=function(a){e&&(f(a,"mouseup"),f(a,"mouseout"),this._touchMoved||f(a,"click"),e=!1)},b._mouseInit=function(){var b=this;b.element.bind({touchstart:a.proxy(b,"_touchStart"),touchmove:a.proxy(b,"_touchMove"),touchend:a.proxy(b,"_touchEnd")}),c.call(b)},b._mouseDestroy=function(){var b=this;b.element.unbind({touchstart:a.proxy(b,"_touchStart"),touchmove:a.proxy(b,"_touchMove"),touchend:a.proxy(b,"_touchEnd")}),d.call(b)}}}(jQuery);

function filterPrice(products) {
  let minP = $("#price").slider("values", 0);
  let maxP = $("#price").slider("values", 1);
  return products.filter(function() {
    let value = parseInt($(this).data("price"), 10);
    return !(value > maxP || value < minP);
  });
}

function filterCheckboxes(products) {
  checkboxes = $("input:checked").filter(function() {
    return $.inArray($(this).attr("name"), ['fl-1', 'fl-2', 'fl-3', 'fl-4', 'fl-5', 'fl-6', 'fl-7', 'fl-8']) != -1;
  }).map(function() {
    return this.value;
  });

  // If no checkboxes are checked, don't filter with them
  if (checkboxes.length == 0) {
    return products;
  }

  return products.filter(function() {
    categories = $(this).data("category").toString().split(" ");
    let val = true;
    checkboxes.each(function() {
      if (!categories.includes(this[0])) {
        val = false;
        return;
      }
    });
    return val;
  });

}

function filterProducts() {
  // Reset filters
  products = $("#products li");
  products.hide();
  products = filterPrice(products);
  products = filterCheckboxes(products);
  products.show();

  let numItems = products.length;

  if (numItems > 0) {
    label = "We found " + numItems + " results";
  } else {
    label = "No results found";
  }

  $("#found").text(label);
}

$(function() {
  let options = {

    min: 500,
    max: 100000,
    step: 500,
    values: [10000],
    slide: function(event, ui) {
      $("#amount").val(ui.values[0] + " USD");
    },
    change: function(event, ui) {
      filterProducts();
    }

  };

  $("input").filter(function() {
    return $.inArray($(this).attr("name"), ['fl-1', 'fl-2', 'fl-3', 'fl-4', 'fl-5', 'fl-6', 'fl-7', 'fl-8']) != -1;
  }).change(filterProducts);

  $("#price").slider(options);
  $("#amount").val($("#price").slider("values", 0) + " USD");

});
