I have an app that was built in an earlier version of ASP.NET 1.1. I have upgraded most of the app to 4.0 (HTML5) and I am trying to set focus to a textbox when a form loads but ever since I have upgraded to IE 11 this is not working. The previous developer has a script on the server side to set the focus to the txtName textbox and injects it before the page renders. FYI, I added a ScriptManager because I added an AJAX control so if that comes into play please let me know
Here is the call to the function in the markup in the body tag.
The underlined piece of code above is what Im trying to get to work. I have tried numerous different types of code snippets but nothing has worked. I actually got it to work momentarily using the .ready function in jquery but have since lost the code and cant get it to work again. I have also tried to add a newer version of a jquery file(jquery-1.12.1.min.js) to see if that would help but it hasnt. I have tried multiple functions like these
1. in place of the underlined code above
' // Reference the textbox
var txt = document.getElementById("<%=txtName.ClientID%>"); 'also tried txtName without ClientID
' // If the textbox was found, call its focus function
if (txt != null)
txt.focus()
2. Also Tried all of these in the markup in the <Head> tag
<script src="Scripts/jquery-1.12.1.min.js"></script> <script type="text/javascript"> $(function () { $("#txtName").focus(function () { alert("hello world"); }) }) </script> <script type="text/javascript" > $(document).ready(function () { $("#txtName").focus(); }); </script> <script type="text/javascript" language="javascript"> function TestFocus() { // Reference the textbox var txt = document.getElementById("<%=txtName.ClientID%>"); // If the textbox was found, call its focus function if (txt != null) txt.focus() else alert("Nothing here"); } </script>
I am curious if maybe I could do this in the CSS instead? Anything that will get this to work I am willing to try. Just a thought...
I must tell you that I am not a javascript/jqeury guy(but I am learning) so its kinda foreign to me so if I am missing something simple dont be surprised. I have been on this for a few days now and need to move on so please help me out. It would be greatly appreciated.
Thanks

If this is a control, you'll need to use $('#<%=txtName.ClientID%>') to target the element. Try this:
There's no need to test for null. If the element doesn't exist on the page, the code will be ignored.

I have tried this and still not working. I believe it is something else going on with this. I can see that the mouseover on the textbox changes the border color but I still cannot click in the text box and enter data. I obviously dont know what it is but I think it could be something else that I may have installed or something else that Im doing/running that is causing this not to work correctly.
I am using HTML5 and I am referencing <script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
Like I said, Im kinda new to javascript and jquery so I am pretty much lost here so ANY help is greatly appreciated..
Thanks

can you post the HTML that's rendered by the control?
I cant get to the page where the focus should be happening now. Somehow I have lost the ability to get to the page ever since I upgraded to IE 11. Its not a javascript error either, I have run the same code on my co-workers machines and it works fine. Ever since I upgraded browsers I have been stuck. I want to check all versions and make sure everything is the same as other developers where it works. If you have any thoughts on where I could check to make sure I am running the correct stuff please let me know. I can show you what I have and maybe we can figure it out...
Thanks for all your help!
Well now I cannot get to the page that I was originally having the problem with. I am getting redirected to a custom Errors page and I cannot find the issue when I am redirected there. I am trying to figure that out now and get back to my original issue. I will check out your link and get back to you...
