推荐答案

您的提交按钮，提高进度条的逻辑需要更正.

您需要做的是，单击提交"按钮时，首先要在客户端进行验证.然后，如果一切正常，则可以让控件流到服务器端.此时，显示进度栏.
逐步执行并更正工作流程.

Your submit button raising progress bar logic needs correction.

What you need to do is, on submit button click, first do the validation on client side. Then if all is fine, you can let the control flow to server side. At this time, show the progress bar.
Do it stepwise and correct the work flow.
