Javascript error in firefox

put the code inside initializing the calendar inside :

window.onload = function() {
     // put INIT ONLY here
}

or use an other plugin :

http://jqueryui.com/demos/datepicker/

Show your line where you call that function NewCal()

Here is my code in the jsp where I am calling the function NewCal()

<netui:image src="/resources/images/cal.GIF"
                                    onClick="javascript:NewCal([getNetuiTagName('dateObserved', this)],'MMddyyyy',false,24);" tagId="calendar" />

As far as I see it should be without squere braces:

<netui:image src="/resources/images/cal.GIF"
                                    onClick="javascript:NewCal(getNetuiTagName('dateObserved', this),'MMddyyyy',false,24);" tagId="calendar" />

You can do a check like this;

<netui:image src="/resources/images/cal.GIF"
                                    onClick="javascript:prompt('id',getNetuiTagName('dateObserved', this));NewCal([getNetuiTagName('dateObserved', this)],'MMddyyyy',false,24);" tagId="calendar" />

Afterwards look into browser page html source for that prompted id.

I found out where the problem was.
The  getElementID() was null in firefox. So when value method was called on that it caused the error.
I had to change it to the following code.
document[getNetuiTagName("formName", scope)][getNetuiTagName("elementId", scope)]

But now I am stuck at this point. When the user clicks on the calendar icon, the calendar displays but it does not select the value.

The code where it is errorring is here.
<a href=\"javascript:winMain.document.getElementById('"+Cal.Ctrl+"').value='"

The message in the error console says that winMain.document.getElementById("portlet_1_2{actionform.date}") is null.  

Can someone please help?

thanks,

yes if you provide a link to see the page

When the user clicks on a date on the calendar, the date is populated in the field in the jsp page.
This works fine in the IE browser. But in the Firefox it gives the error that winMain.document.getElementById("portlet_1_2{actionform.date}") is null.  

I believe the value 'portlet_1_2{actionform.date}' is the field from the jsp.

I am using netui tags in the jsp.
When I am using the regular html tags, this works perfectly fine.

I am not sure which page you would like to see. I have already uploaded the javascript file.
I am pasting below the part of the code in the jsp where we invoke the javascript function.

<tr>
                                <td width="250"> Date situation was observed ** </td>
                                <td colspan="3">
                                <netui:textBox dataSource="actionForm.date" tagId="dateObserved"/>
                                <netui:image src="/resources/images/cal.GIF"
                                                      onClick="javascript:NewCal(getNetuiTagName('dateObserved', this),'MMddyyyy',false,24);" tagId="calendar" />
                                         
                                </td>
                            </tr>

Naming rules:

Must begin with a letter A-Z or a-z
Can be followed by: letters (A-Za-z), digits (0-9), hyphens ("-"), underscores ("_"), colons (":"), and periods (".")
Values are case-sensitive

portlet_1_2{actionform.date}

just a thought...

Thanks for pointing out.

It may not recognize the curly braces  { }. But the value 'portlet_1_2{actionform.date} is generated by the weblogic portal.  

I found this solution from other sources
