如何在UI上动态显示图片？

标签： javascript jquery html css html-table

我正在显示由HTML表和图像组成的屏幕，而HTML表是完全动态的。

代码工作流程

当用户正在加载页面（带有URL）时，我在不同部分渲染HTML表，这意味着该页面已加载。我要一次获取所有JSON格式的表数据，然后一次在UI的gap（Interval）的3 seconds上显示3-3行，当加载完整表时，我显示图像一段时间，然后再次加载表格并在加载表格后显示图像，所以它工作正常，现在我要做的是动态显示图像

我要做什么

当前，我的操作类似于<img src="Image/Counter A/CounterA1.jpg" alt="Some Image" width="460" height="345">，因为文件夹中仅显示一个图像，但是现在Counter A有两个图像或3个图像或其他可能的图像，所以当页面加载时像这样var images = {"Counter A":["CounterA1.jpg", "CounterA2.jpg"]}的对象中要为哪个计数器A加载哪个图像，对于其他计数器也同样有两个图像，所以我想做的是先加载表，然后在加载表完成时尝试显示< strong>第一个图片比再次加载表要比显示图片2 这就是为什么在数组中有“图像”链接的原因，我唯一的问题是一次显示一个图像

工作过程

表加载-> 3秒后->表的下3行，直到表的最后一页->显示Image1（CounterA1.jpg）->再次加载表->显示Image2（CounterA2.jpg）->然后再次表->然后再输入Image1，因为只有两个图像

我已经完成了显示HTML表和仅显示一个图像的图像的操作，现在我想静态地动态进行操作

为了更好的理解，我已经注释掉了JS代码中的所有行，正如您在上传的图片image中看到的那样，这是公用文件夹，因此我可以在{{1} }并反击他们的图片src

修改

我添加了以下代码

var images = {"Counter A":["CounterA1.jpg", "CounterA2.jpg"]}

我做得还多，我想我已经接近了预期的结果，问题是它在另一个下面显示了一个图像，这是不正确的，我试图做的是在有两个图像的情况下->图片1，表格->图片2，但在表格后，这两个图片都在另一个下方呈现，请检查我的代码段

这是我的图片呈现Check this

的方式

还有This

My Image Folder

答案 0 :(得分：1)

尝试这样。

我引入了一个新功能来格式化HTML中的图像。然后得到它的长度和循环，引入一个cnt（count）变量并使它递增。并用模取数字并重复图像。

var imgLen = 0;
var cnt = 0;
