webber007 · web-flow · commit 40d8c12be807 · 2017-05-17T17:23:39.000+08:00
报错：
Cannot read property 'images' of undefined;at "pages/detail/detail" page wxParseImgLoad function
TypeError: Cannot read property 'images' of undefined

加了个不存在的return情况 
if (!temData || temData.images.length == 0) {
    return;
  }
