... wrap it in a function and call it onload of your body ... this will work ;)

in case you want to have the textbox always readonly then you may do:

[HTML]<input type="text" name="whatever_ name" id="whatever_id " readonly="true"/>[/HTML]

this works too ... ! in case you want to enable it during runtime ... call a function that removes the attribute the way i showed you ...

kind regards ...

explaination: onload of the document's body all elements are already rendered by the browser engine and then you may refer to them using javascript ... the way you did javascript should throw an error from getElementById( ) ... have a look at the js-console

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
