我有一个在内部div中包含标签的帖子链接列表。用户从三个不同的列表中进行选择以过滤帖子。
基本上我想要实现的是基于用户选择的三个列表内容的前端过滤。
我希望逻辑基本上是这样的:IF post-tags-list has 1+ item from list1 AND has 1+ item from list2 AND has 1+ item from list3, THEN keep the post
以下是我的开始,但目前的方式是,如果某人没有从其中一个列表中选择任何内容,我需要大量的IF
语句来解释。我知道开关可能更容易,但我不完全确定我的逻辑是否正确。
$(".post-link").each(function(index){
//Get all the post's terms from its hidden tag div and store in an array
var terms = $(this).find(".tags").attr('class').split(" ");
//Cut off the first two items ('hidden' and 'tags')
terms.splice(0,2);
//If interests is set
if(typeof interests[0] != 'undefined'){
var found = 0;
var keep = false;
//For each of the selected interests...
$.each(interests, function(index, value){
//For each of the posts terms
$.each(terms, function(index2, value2){
//If the posts has a selected interest, keep it
if(value == value2){ keep=true;}
});
});
//After all that, if we couldn't find anything...
if(keep!=true){
//Hide the post (.post-link)
$(this).hide();
}
}
//THE ABOVE ONLY ACCOUNTS FOR IF SOMETHING IS SELECTED FOR THE FIRST LIST
//I'M NOT SURE HOW I WOULD IMPLEMENT THIS ACROSS TWO OTHER LISTS
});
如果您需要更多信息,请与我们联系。
谢谢!

好的,所以我找到了问题的解决方案。基本上对于每个帖子,我设置一个show变量并将其设置为true(我们希望显示帖子,除非另有证明)。所以我检查我的三个列表中是否有其中的内容,如果我这样做,那么在foreach中做一个foreach以检查我的一个帖子术语是否与我选择的项目匹配。如果有,请保持show = true,否则为false。为其他两个列表执行此操作。在这三次检查之后,如果show仍然是真的,那么每三个字段中至少有一个项目(如果有三个适用),如果它是假的,则隐藏帖子。
以下是代码:
$(".post-link").each(function(index){
var show = true;
//Get all the post's terms from its hidden tag div and store in an array
var terms = $(this).find(".tags").attr('class').split(" ");
//Cut off the first two items ('hidden' and 'tags')
terms.splice(0,2);
//If interests is set
if(typeof interests[0] != 'undefined'){
var found = 0;
$.each(interests, function(index, value){
$.each(terms, function(index2, value2){
if(value == value2){ found++; }
});
});
if(found < 1){
show = false;
}
}
//If type is set
if(typeof type[0] != 'undefined'){
var found = 0;
$.each(type, function(index, value){
$.each(terms, function(index2, value2){
if(value == value2){ found++; }
});
});
if(found < 1){
show = false;
}
}
//If experience is set
if(typeof experience[0] != 'undefined'){
var found = 0;
$.each(experience, function(index, value){
$.each(terms, function(index2, value2){
if(value == value2){ found++; }
});
});
if(found < 1){
show = false;
}
}
if(!show){
$(this).hide();
}
});
