Underscore.js檢查數組值是否等於另一個數組中的項

Question

我有以下的underscore.js模板。我想檢查數組值是否等於pubHols數組中的日期。這是什麼語法？

var pubHols = [ 
    { date: '2015-12-25', title: 'Christmas Day' }, 
    { date: '2015-12-28', title: 'Boxing Day' }, 

]; 



    <% _.each(days, function(day) { %> 
    <% if(day.date == pubHols.date){ %> 
     <div class="pubHol"><span class="day-number"><%= day.day %></span></div> 
    <% } %> 
    <% }); %> 

Answer 1

您可以使用findWhere

<% if(_.findWhere(pubHols, { date: day.date })){ %>
