blazy.js简单的例子不起作用

问题描述 投票:1回答:2

1.总结

简单的blazy.js示例对我不起作用。我不明白,我做错了什么。


2.设置

我下载并初始化blazy.js写为in official site

我的示例标记:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <script src="https://cdn.jsdelivr.net/blazy/latest/blazy.min.js"></script>
    <script>
    var bLazy = new Blazy({
    });
    </script>
</head>

此代码在演示页面中:https://kristinitatest.github.io/Stack%20Exchange/HTML+CSS/Blazy/BlazyTest.html


3.重现的步骤

我打开https://kristinitatest.github.io/Stack%20Exchange/HTML+CSS/Blazy/BlazyTest.html→我打开Firefox内置控制台。


4.预期的行为

延迟加载图像。


5.实际行为

在Chrome中重现。

网页中的所有图像立即为我下载,而不是延迟加载。


6.没有帮助

  1. 我为所有图像添加src属性,
  2. 我用blazy options
  3. 我使用图像的相对路径而不是绝对路径。

我没试过,但在blazy.js page看看这个:

  1. 将blazy.js添加到您的网站
  2. 将'b-lazy'类添加到应该延迟加载的元素中
  3. 只要你准备好就初始化blazy

你做了1,3,2而不是1,2,3。这可能是问题所在。

我早一点遇到同样的问题。

我认为Bjoern Klinggaard忘记在文档中强调的一件事是需要占位符图像。一旦你把它放在那里,它就会起作用。

例如,而不是:

 <img class="b-lazy" data-src="https://i.imgur.com/OJSBK4V.jpg">

添加占位符图像,例如:

 <img class="b-lazy" data-src="https://i.imgur.com/OJSBK4V.jpg" src="http://placehold.it/500x250&text=placeholder" >

这对我来说很有用。试一试。

希望这可以帮助!

*请注意,我使用的是blazy v1.8.2 - 2016.10.25

此解决方案可能不适用于其他版本。但是,由于它是在原始海报消息之前发布的,因此该解决方案仍应有效。
