Javascript SyntaxError:OpenCart站点中出现意外令牌,javascript,opencart,opencart2.x,opencart-module,Javascript,Opencart,Opencart2.x,Opencart Module,每次我们点击OpenCart软件中的链接时，我都想要一个旋转器。所以我使用了以下代码： <style> .se-pre-con { position: fixed; left: 0px; top: 0px; width: 100%; height: 100%; z-index: 9999; background: url(img/loader.gif) center no-repeat #fff; } </styl

每次我们点击OpenCart软件中的链接时，我都想要一个旋转器。所以我使用了以下代码：

<style> 
  .se-pre-con {
    position: fixed;
    left: 0px;
    top: 0px;
    width: 100%;
    height: 100%;
    z-index: 9999;
    background: url(img/loader.gif) center no-repeat #fff;
}

</style>

<div class="se-pre-con"></div>

<script>
//paste this code under head tag or in a seperate js file.
  // Wait for window load
  $(window).load(function() {
    // Animate loader off screen
    $(".se-pre-con").fadeOut("slow");
  });
</script>


.se预检{

}
//将此代码粘贴到head标记下或单独的js文件中。
//等待窗口加载
$（窗口）。加载（函数（）{
//在屏幕外设置加载程序动画
美元（“.se pre con”）。淡出（“缓慢”）；
});
此代码将在每次加载页面时加载微调器（loader.gif）

所以我转到index.php页面，修改了文件，如下所示

首先不要修改索引文件（更新时可能会丢失文件，而且这是一种不好的做法）

只需修改模板文件的
header.tpl
，即可放入脚本


// catalog/view/theme/default/template/common/header.tpl:39
     <style>
        .se-pre-con {
          position: fixed;
          left: 0px;
          top: 0px;
          width: 100%;
          height: 100%;
          z-index: 9999;
          background: url('catalog/view/theme/default/image/loading.gif') center no-repeat #fff;
        }
      </style>

<script>
    //paste this code under head tag or in a seperate js file.
    // Wait for window load
    $(window).load(function() {
      // Animate loader off screen
      $(".se-pre-con").fadeOut("slow");
    });
  </script>



//catalog/view/theme/default/template/common/header.tpl:39
.se预检{
位置：固定；
左：0px；
顶部：0px；
宽度：100%；
身高：100%；
z指数：9999；
背景：url（'catalog/view/theme/default/image/loading.gif'）中心不重复35; fff；
}
//将此代码粘贴到head标记下或单独的js文件中。
//等待窗口加载
$（窗口）。加载（函数（）{
//在屏幕外设置加载程序动画
美元（“.se pre con”）。淡出（“缓慢”）；
});


现在位于
标题.tpl
正文


PS：好的做法是使用样式表的样式文件、js的脚本文件和html的
.tpl
文件
 你忘了在
url（img/loader.gif）
中加引号。将其替换为
url（“img/loader.gif”）
也许这是由于**和**试图删除它没有修复的**@Sapikelio造成的。我尝试了两种方法。@shock\u gone\u wild**被保留，以使其在Stackover flow中更加大胆。我现在就纠正它。
