SyntaxError：rails app中未终止的字符串文字

Question

我在这里得到了上述错误。我的代码是

 $("#customers").append(
                            '<%= select_tag "customer_id", options_from_collection_for_select(@customers, "id", "name"), include_blank: true %>'
                    );

在控制台中，它指向此行的错误

'<select id="customer_id" name="customer_id"><option v

Answer 1

尝试添加escape_javascript，如下所示，这将解决您的问题。

$("#customers").append("<%= escape_javascript(select_tag('customer_id', options_from_collection_for_select(@customers, :id, :name), include_blank: true)) %>")

Answer 2

使用双引号（＆＃34;＆＃34;）而不是单引号（＆＃39;＆＃39;）： -

$("#customers").append("<%= select_tag 'customer_id', options_from_collection_for_select(@customers, :id, :name), include_blank: true %>")
