uck offult的语法：意外的标识符下划线_.template

Question

我正在使用下划线库，并使用其模板功能。

但是我遇到了一个奇怪的问题 Uncaught SyntaxError: Unexpected identifier. 。生成此问题的代码是：

window.JST['product_icon'] = _.template('<div\nid="product_icon_<%= product.id %>"\nclass="product_icon itemSpacer"\ndata-product-id="<%= product.id %>">\n\n  <div\n  class="sticker item hide"\n  <% if (product.images and product.images.length) { %>\n  style="background-image:url(\'/assets/products/<%= product.images[0].id %>/small/<%= product.images[0].attachment_file_name %>\');"\n  <% } %>>\n\n    <div class="data-container">\n      <small class="id"><%= product.id %></small>\n      <div class="description">\n        <div class="background"></div>\n        <div class="text">\n          <a href="#" class="add-to-cart">\n            Add to cart\n          </a><br/>\n          <a href="<%= \'/products/\' + product.permalink %>" class="view-sticker-details">\n            View this sticker\n          </a>\n          <br/>\n          <a href="#" class="FPO-load-brands">\n            View all brand Stickers\n          </a>\n        </div>\n      </div>\n    </div>\n  </div>\n</div>\n');

我尝试了所有事情，但无法识别问题。

Answer 1

它是 if (product.images && product.images.length) 并不是 if (product.images and product.images.length) ;)
