[@brettaylor2661]

Thank you for the video. I'm not to the point where I can understand it but it gives me a goal to aim for.

[@nathanonthenet]

Thanks for the tutorial. I have been following your posts. This is the perfect example of front end + back end programming. Is there a reason why you use asmx instead of svc for the web service?

great work Sir

Sir, I have one problem that I encounter while I do accessing web services from AJAX. I uncommented the following ([System.Web.Script.Services.ScriptService]) line but its not picking up. I have red underline in Script. Also, in the line using System.Linq; Linq is underlined. I tried adding reference to System.Web.Extensions as welland Linq reference too, its not helping me out.

I'm getting a web console 404 error when I type anything in the text box. The webservice may not be referenced in my Visual Studio project, but I'm not sure how to do that, can anyone help?

[@musiceverydayproductions]

I get an alert saying [Object, Object].

[@afeworkhaile7317]

I see that a lot of people commented on this video as wonderful and helpful. However, the code doesn't even work and it is sad to see that people are commenting without even checking if it works. Also, I want to say that what this video shows in the last 10 seconds is slightly different from how it looks in the earlier minutes, which I find it confusing why you showed different codes in the last few seconds. I know your videos, in general, are good and educational but this particular video has issues and the code doesn't work. I followed your codes step by step but at the end, I get an alert saying [Object, Object].

What if JavaScript is turned off by the end user

[@jogex123]

+Bright Ileh You need to run these types of checks through php also. Once posting the form PHP needs to double check everything for security reasons.
