OnBlur of one field, Set Focus on another

[kingcarol]

Want to use XBasic function in the OnBlur event of one field to set focus on another field, based on certain conditions. I've been searching this board and Alphapedia to confusion point. If someone knows how to set focus on a field, can you give me an example and not just the syntax?

in Access, it was so simple..... fieldname.SetFocus
ahhhhh well

Have you seen this?

Just watched it. Good stuff to know. Thanks. Although I am still wanting to know what javascript or Xbasic is used to set focus on another field.

Another question. Are you familiar with Action Scripting? It can be used to create the code you need. Let me know and I can guide you through it.

No, I'm not familiar with it. Tell me more.

Open any form to design mode on the desktop. If you create a new one, put a few fields on it.

Open the dropdown tool bar and select the Button tool; put a button on the form. When the window pops up, select the Action Scripting radio button near the bottom. Press Next and the Press Add New Action. On the right side, press Activate an Object under the Action section. Follow the prompts.

When done, right click on the button and select Events->OnPush. You'll see the action script you just created. Click the Convert to Xbasic action icon just to the left of the lightening bolt.

Now, you'll see the xbasic code which is more than what's needed cuz AS created it. Copy the code and make the changes to reflect your situation. You can experiment on the form by removing some of the code until you get to the minimum needed if desired.

I think you'll find AS will open a whole new world for you. I use it quite often to generate code and then make the changes. It's a fabulous learning tool as well as a great time saver.

I played around with all of that, Ken. Thank you. Looks like it could give me some clues.

I couldn't find any Xbasic action for setting focus on a field there, though.

Have just spent last hour trying to use javascript everywhere, on button click, in javascript function, then function in button, but to no avail.

This is what I using in my failed attempts:

{
document.getElementById("fname").focus();
}

Carol,

Maybe this thread will be of help. Look at the last post. I haven't tried it but it looks promising.

Re: OnBlur of one field, Set Focus on another

This is some example code for release notes last year which may help.

var rowNumber = {grid.object}._selectedRow;
var ele = $('{grid.componentname}.V.R' + rowNumber + '.NAMEOFFIELDTOGETFOCUS');
ele.focus();

Re: OnBlur of one field, Set Focus on another

Just found another thread, too. Selwyn put the code needed in this thread:
http://msgboard.alphasoftware.com/al...ht=afterselect

NOTE: I tried this with the OnBlur event and got an endless loop, so I don't think that's a good idea. It could be because I was also trying to pop up an alert message which blurred the field again and again. Not sure. But when I tried this code just to see if it worked on a button, it did.

var ele = $('{grid.componentname}.V.R'+{grid.object}._selectedRow+'.FIRSTNAME').focus();

Re: OnBlur of one field, Set Focus on another

It seems like the only way you could get an endless loop is if you were specifying the field name in the same fields onBlur event.

Re: OnBlur of one field, Set Focus on another

Just to elaborate on what I'm attempting to do:

Use OnBlur event to check whether a user had emptied the field and then give them message (alert) that the field cannot be blank. I want this to happen as soon as they emptied a field instead of waiting for the Submit to show the error. Then after the message I want the focus to be reset to the field that they had emptied. The code below works fine but if I put in the set focus code, it causes an endless loop, so it's not in the javascript area right now. Basically, I don't know where to put it:

function DocTitle_OnBlur as c (e as p)
'This function will check to see if the value in the field is empty
'and give the user a message that the field cannot be left empty.
'Would like it to ALSO move the focus back to the field using this:
'var ele = $('{grid.componentname}.V.R'+{grid.object}._selectedRow+'.DOCTITLE').focus();
	
	dim jscmd as c
	
	dim FieldValue as c
	FieldValue = e._currentRowDataNew.DocTitle
	
	If FieldValue = "" then
	    	    	    
	  	jscmd = <<%js%
		alert('Please enter a unique File Title.  The field cannot be left empty.');
		%js%
		
		DocTitle_OnBlur = jscmd
		
	end if
		
end function

Re: OnBlur of one field, Set Focus on another

Carol,

Why wouldn't you use the fields validation rules for this operation?

Just select Require value.

nevermind.. I re-read what you are trying to do.

[kingcarol]

Re: OnBlur of one field, Set Focus on another

Yep, I already had the field validation set to Require Value. but, like you reread, I want user to know about a blank field issue long before they Submit. That's partly because some fields and their auto suggest lookups are filtered based on some values in previous fields. I don't want them to get all perplexed when getting to those lookup fields. BTW, Auto Suggest lookups make it so that most field events aren't recognized.

Since this is a Job Costing program, I want to figure this out. For example, there could be a JOB_CODE field in their data entry where they select a Job Code. Then later in their entry, there could be a PO Number field that looks up PO's for the selected Job Code. In the lookup, I need to display more than one field (PO number, title, amount, etc), so dropdown box doesn't work well for that. Therefore, I am stuck with auto suggest field and I wouldn't want the earlier JOB_CODE field to be blank, thus causing user confusion.

Re: OnBlur of one field, Set Focus on another

OK this works in IE but does not seem to set focus back to the field in FireFox.

Create a div with an id of 'ErrorMessageDiv' on your grid somewhere to display the message. Put this code in the onBlur event of the field you want to validate. You may have to still use the field validate event to prevent them from saving.
You could expand on this by making the texbox red, text red etc. with a little more code.

var vFieldValue = this.value;

if (vFieldValue.length == 0)
{
	this.focus();
	$('ErrorMessageDiv').innerHTML='Can\'t be empty';
}
else
{
	$('ErrorMessageDiv').innerHTML='';
}
