我正在显示我提供的课程，并使用Javascript / jQuery基于元素类显示/隐藏。
页面位于：http://dev.sharepoint-videos.com/sharepoint-2013-training-courses-dev/
基本上，脚本会隐藏页面上的所有内容，然后显示与类选择器匹配的项目，该选择器由下拉列表和复选框选项组成。一切都很好，除了我想允许在多个过滤器适用时保持结果静止的外观。例如如果他们选择作者，然后选择级别，然后观众，我希望适用于所有3个选择器的课程保留，而其他选择器隐藏。

我选择了克里斯的建议并根据不匹配的元素推迟了隐藏。
function ApplyFilters() {
var effect = 'magictime swap';
var reseteffect = 'magictime twisterInUp';
var courses = jQuery(".courseContainer");
jQuery("p.zeroResults").text("").css("margin-top", "0px");
courses.removeClass(effect);
courses.removeClass(reseteffect);
var speakerFilter = jQuery("#author_filter").val();
var levelFilter = jQuery("#level_filter").val();
var audienceFilter = jQuery("#audience_filter").val();
var Office365Filter = GetOffice365Value();
var classFilter = speakerFilter + levelFilter + audienceFilter + Office365Filter;
courses.not(classFilter).hide();
if (classFilter == "") {
courses.hide().addClass(effect).show();
} else {
var count = jQuery(classFilter);
if (count.length > 0) {
jQuery(classFilter).show();
} else {
jQuery("p.zeroResults").text("No Results Match Your Select. Please 'Reset' your filters").css("margin-top", "-50px");
}
}
