Question

我在使用Uncaught error unexpected token (循环的字符串script标记中收到错误for

<script type="text/javascript">
   var offer_foto_index = 'slide_offer_preview_1';
   var slide_offer_preview_ = [];
   var photo_array = <%= @photos.to_json.html_safe %>;
   var offer_foto = {
     for(var i = 0; i < <%= @photos.length %>; i++) {
       slide_offer_preview_[i] = photo_array[i];
     }
   }
</script>

我需要一个offer_photo变量，该变量应包含数组slide_offer_preview_1，slide_offer_preview_2，slide_offer_preview_3等。

我在哪里弄错了？谢谢！

如果没有看到您的实际渲染代码是什么样的，这将很难。但我的猜测是你应该使用photo_array代替@photos：

<script type="text/javascript">
   var offer_foto_index = 'slide_offer_preview_1';
   var slide_offer_preview_ = [];
   var photo_array = <%= @photos.to_json.html_safe %>;
   //var offer_foto = { - I've commented this because you don't need it...
     for(var i = 0; i < photo_array.length; i++) {
       slide_offer_preview_[i] = photo_array[i];
     }
   //}
</script>

根据你的评论回答：“......我需要一个offer_photo变量。它应该包含像slide_offer_preview_1，slide_offer_preview_2等数组。”

<script type="text/javascript">
   var offer_foto_index = 'slide_offer_preview_1';
   var slide_offer_preview_ = [];
   var photo_array = <%= @photos.to_json.html_safe %>;
   var offer_foto = {};
   for(var i = 0; i < <%= @photos.length %>; i++) {
     offer_photo['slide_offer_preview_' + i] = photo_array[i];
   }
</script>

或者如果你需要它在“offer_foto”对象中的一个数组中：

var offer_foto = {};
offer_foto.slide_offer_preview_ = [];
for(var i = 0; i < <%= @photos.length %>; i++) {
  offer_photo.slide_offer_preview_[0] = photo_array[i];
}
