我在页面上有以下HTML代码，我试图在每个Feed项后添加一小段html。但是我有很多饲料项目，但只希望html只显示三次。
HTML：
<div class="wp_rss_retriever">

这是我用来在每个feed项后添加一段html的JQuery代码。它工作正常，但我很难找到一种方法来修改它，所以html只显示三次。
$(function() {
$("<p>Test</p>").insertAfter(".wp_rss_retriever_container");
})
答案 0 :(得分：0)
只需迭代元素，然后对循环发生的次数进行硬性检查。
$('.wp_rss_retriever_container').each(function(index, element){
if(index < 3){
$(this).after('<p>Test</p>');
}
});
我认为这是你想要实现的目标。
