如何在完成方法时显示和隐藏进度图像而不是完成事件？ [英] How can i display and hide progress image on completion of methods and not complete event?

问题描述

我有一个带有五个上传控件的网页表单，文件正以这种方式上传...

I have a web form with five upload controls and files are getting uploaded in this way...

if (file1.ContentLength > 0)
            {

                //somecode to insert
            }

if (file2.ContentLength > 0)
            {

                //somecode to insert
            }

if (file3.ContentLength > 0)
            {

                //somecode to insert
            }

I想要显示一个gif图像或每个控件旁边的东西，只要它正在进行中。

I want to show a gif image or something next to every control which has a file as long as its in process.

推荐答案

在Jquery的帮助下，你可以实现这一点!!!



你需要拿一个div，进入那个div需要先用diplay：none调用img。



使用ajax调用时点击上传控件需要显示和隐藏div。



希望，你会明白的。随意询问是否有任何问题!!!!

With the help of Jquery, u can achieve this!!!

U need to take a div, into that div to need to call the img with diplay:none initially.

While using ajax call on click to upload control to need to show and hide the the div.

Hope, u will understand. Feel free to ask if any issues!!!!
