JSF - Auto Tab To Next Field

Posted on 2008-10-02
Last Modified: 2013-11-24

How can I implement jumping to next field after user enters all the required number of characters?
The document.getElementById('FieldId') ALWAYS returns null!!.

I have code like this

<h:inputtext id "FieldText"  maxlenght = "5" ....... onkeyup ="AutoTabToNextField(this, 'NextField')" />
h:inputtext id = "NextField" ,,,, />

My javascript looks like:

AutoTabToNextField(F1, F2)
  // This is the problem. No Matter what method I use to pass reference to F2,
 //  F2 is ALWAYS ALWAYS NULL or is not an OBJECT!!!

// F1 is passed correctly ... ALWAYS .. I think it is because of using "this"

  if (F1.value.length == F1.maxLength)

Hello FarzadA:

I think I have tried that as well and it did not work. However, let me try one more time. I will update you with the results.

I found the solution. I had to call my JS function with refernce to nextField as 'formID:FieldID'. Yes it is colon. The way I figured it out was to look at the HTML source created by the JSP and look at what are the ids for different fields. Then, within the function, I get the reference to the field by using document.getElementById to set the focus.

Since FarzadA started my thinking process which led me to a solution, I will award him full points. Thanks for your help FarzadA.

'formID:FieldID' is JSF naming. You can use forceId=true attribute in inputText tag to force JSF use you id.

<h:inputtext id="NextField" forceId="true" ....

Now you can use its id without pointing to 'formID:'
