Moss 2007 FAQ: Enable/ Disable fields with selection of radio button in Moss 2007

By Mario Fernandes

Query by Biplab Mitra: 

I need some help from you regarding MOSS.

I need to enable/disable some fields with the selection of radio buttons.

How can I add JavaScript to the fields in the list? As I am unable to get the field ID.

Even I need to add some logic for calculating some fields with the selection of the radio buttons.

Solution by Mario Fernandes

• Open the List.  ( I am assuming its Employee list.)
   

• Pick any one record & go in edit mode.
   

• Right click on the page & View Source
   

• Search for <form element  - note down the “name” value
   

• Search for the field you wish to make read only say “EmployeeName”. Check <input element next to it – note down the “name” value
   

• Copy the URL of this EditForm.aspx
   

• Open Sharepoint Designer, File à Open à paste the url you copied

• Go to code window.
   

• Locate <IMG src="/_layouts/images/blank.gif"
   

• Just after this <Img> element put this code  ---      document.formname.inputfieldname
   

• <script type="text/javascript" language="javascript">document.aspnetForm.ctl00$m$g_bf411c27_b525_4df6_a7f3_a64ee5b5aef3$ctl00$ctl04$
  ctl01$ctl00$ctl00$ctl04$ctl00$ctl00$TextField.disabled="true";</script>
   

• Save the form. Refresh the page.
   

• There you go.
