Underscore.js检查数组值是否等于另一个数组中的项

Question

我有以下underscore.js模板。我想检查一个数组值是否等于pubHols数组中的日期。这是什么语法？

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 })){ %>
