Javascript 无法识别的表达式：。fancybox_#

我有图像视图，在图像上单击我需要打开fancybox

这是我的查看代码

但是现在我在页面加载时出错了

语法错误，无法识别的表达式：.fancybox_35;{hotel.id}

我如何解决这个错误

感谢您的帮助。

$（'.fancybox{hotel.id}'）

不是有效的选择器。看起来您没有正确使用模板引擎（对不起，我不熟悉Ruby）

除非使用类似gem或类似技巧，否则无法将rails变量传递到javascript（资产）文件中。如果您的脚本非常简单，我认为您应该将其保留在html rails视图中

<%= javascript_tag "$('.fancybox_#{hotel.id}').attr('rel', 'gallery').fancybox({ prevEffect : 'none', nextEffect : 'none',  closeBtn : true, showNavArrows: true, beforeShow : function() { var alt = this.src; this.title = alt; }, helpers : { title : { type : 'inside' }} });" %>

$('.fancybox_#{hotel.id}').attr('data-fancybox', 'gallery').fancybox({ prevEffect : 'none', nextEffect : 'none',  closeBtn : true, arrows: true, beforeShow : function() { var alt = this.src; this.title = alt; }, helpers : { title : { type : 'inside' }} });
