如何在UI上动态显示图像? [英] How to display Image dynamically on UI?

问题描述

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.

I am working on Displaying a screen which is consist of HTML table and Image, an HTML table is fully dynamic.

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.我一次获取所有JSON格式的表数据，然后一次在3 seconds的gap(Interval)的UI上一次显示3-3行，当加载完整表时，然后显示一段时间之后，再次加载表格并在加载表格后显示图像，所以它工作正常，现在我想做的是动态显示图像

When user is loading a page (With URL) I am rendering a HTML table in different parts which means that page is loaded. I am Getting all the table data in 'JSON' format at once and then showing 3-3 rows at a time on UI in the gap(Interval) of 3 seconds When full table is loaded Then I am showing The Image for some time and after that again loading Table and showing image once table is loaded, So it is working fine,Now what I am trying to do is Show the Image dynamically

我要做什么

目前，我的操作方式与<img src="Image/Counter A/CounterA1.jpg" alt="Some Image" width="460" height="345">相似，因为文件夹中仅显示一个图像，但是现在Counter A具有两个图像或3个图像或其他可能的图像，所以当页面加载时，我得到的是哪个图像像这样在计数器A的var images = {"Counter A":["CounterA1.jpg", "CounterA2.jpg"]}对象中加载同样有两个其他计数器的图像，所以我要做的是先加载表，然后在加载表完成后尝试显示第一个图像加载表，而不是显示图片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

Currently I am doing it like <img src="Image/Counter A/CounterA1.jpg" alt="Some Image" width="460" height="345"> because there was only one Image to Show in folder, but now Counter A has two Images or 3 or whatever it may be So When Page is loading I am getting the Which Image is to be loaded in object like this var images = {"Counter A":["CounterA1.jpg", "CounterA2.jpg"]} for Counter A there are Two Images similarly for other counters also, SO what I am trying to do is Load table first then, When loading table completed trying to show first Image than again load table than show Image 2 That's why I have Images link inside an array, my only Issue is to show one Image at a Time

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

Table loading -> after 3seconds -> next 3 rows of table until the last page of table -> show Image1 (CounterA1.jpg) -> load table again -> show Image2(CounterA2.jpg) ->then again table -> then again Image1 because there are only two Images

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

I have already done showing HTML table and showing Image with only one Image and statically now I want to do That dynamically

为了更好的理解，我已经注释掉了JS代码中的所有行，在这里您可以在上传的图片中看到image是公用文件夹，因此我可以在src中手动设置它，并对其计数器和它们的图像进行设置我越来越像这样var images = {"Counter A":["CounterA1.jpg", "CounterA2.jpg"]}

I have commented out all the lines in my JS code for better Understanding, here as you can see in my uploaded picture image is common folder so I can set it manually at src and counter and their Image I am getting like this var images = {"Counter A":["CounterA1.jpg", "CounterA2.jpg"]}

修改

我添加了以下代码

        var images = {"Counter A":["CounterA1.jpg","CounterA2.jpg"]} // Images to be load on UI

            for (var key in images) {

            var imageList = images[key];
             console.log(imageList.length)
             for (i = 0; i < imageList.length; i++) 
                 {
                 console.log(imageList[i])
                 var img = $('<img />').attr({
                        'src': 'Image/'+key+'/'+imageList[i] , // this one is displaying Image one below other
                        'alt': 'Some Image',
                        'width': 90+"%",
                        'height':680
                    }).appendTo('#displayImage'); 
                 }

            }

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，但在此表格之后，这两个图片都在另一个下方呈现，请检查我的代码段

I have done bit more I think I am near to get the expected result, The issue is it is showing Image one below other which is not true what I am trying to do is when there are Two Images then table --> Image1, table --> Image2 but here after table both Image are rendering one below other please check my snippet

这是我的图像呈现方式

This is how my Image is rendering

和

推荐答案

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.并使用取模运算来找到数字并重复图像.

I have introduced a new function to format image in HTML. and then got its length and loop introduced a cnt(count) variable and made it to increment. and used modulo to find the number and repeated the images.

var imgLen = 0;
var cnt = 0;
