Selecting a Text Field on Page Refresh

I have the following simple page. I need to select the BARCODE text field everytime the page refreshes. I know this is pretty basic, but I'm just starting with Javascript. Thanks for the help.

just insert:

Expand|Select|Wrap|Line Numbers

<BODY onLoad='document.getElementById("t_1_value").focus();'>

One tip from a long-time expert: don't use generators for your page, just learn HTML and do it manually!
Garbage like

Expand|Select|Wrap|Line Numbers

<p class=MsoNormal><o:p> </o:p></p>

is an indicator that you used Microsoft Word or another microsoft-office-product to make this page!
They are doing nothing except slowing down your page and making modifications very difficult!

That wouldn't quite work because the ID hasn't been set. If the id of the text field is set to "t_1_value" , it should work as expected.

Agree with your tip :)

Agree with your tip :)

But what you said is wrong for IE, I tested it.

example code, test it yourself.:

Expand|Select|Wrap|Line Numbers

 <input type=text name="myBox">

<input type=text onChange="alert('You entered above: ' + document.getElementById('myBox').value)"'>

It seems that if an element does not have an "id", but a "name", then
getElementById( ) fetches the element as though the name would be its id.

Yes, I know that "works", but it's wrong and buggy. document.getEle mentById() should only fetch an element by its ID as its name suggests, not the element's name. This won't work in any of the other browsers.

To fetch an element by its name, we have document.getEle mentsByName().

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
