Start C validating textbox input

C validating textbox input

In the app I am working with I do have a pop-up window that shows a html version of all the errors in the input (not only textboxes and intboxes but also in listboxes, radiogroups and so on), but it would also be nice to get the error message to show up on the respective component, at least for text- and intboxes. @Rico You can try to give the component a constraint, just like checkbox Constraint(No Empty Constraint), and customize the constraint by your own.

may understand as a developer, but that your user may not.

You can write a Java Script form validation script to check whether the required field(s) in the HTML form is blank or not.

video_library Watch Java Script form validation video tutorial. Javascript function to check whether a field is empty or not At first the function required() will accept the HTML input value through inputtx parameter.

Regards, Yes, of course I can do my own validation but I won't get the same "look-and-feel" as I get from the constraint message boxes.
