SharePoint – Publishing Page Validation

Hi Everyone,

Today new issue and solution 🙂 small article but since it took time to solve me so thought to share.

Background: I have a Publishing page layout on which I have some custom fields. For these fields I need to have a validation. So, I used PreSaveItem() function in my JavaScript code for validation but it only works on NewForm.aspx and EditForm.aspx pages in SharePoint and not on publishing page.

Solution:

  • If you inspect Save button on publishing page. You will find that CoreInvoke() function is getting called on button click as shown in fig.

  • We have to override CoreInvoke() method.
    CoreInvoke = function(action, target)
  • This method should be executed when user click Save button on when publishing page is in edit mode.
  • Put the following code in your js. The code should be executed only when action is PageActionClick.
//override the CoreInvoke function
CoreInvoke = function (action, target)
{
    If(action == ‘PageActionClick’)
    {
        //Your validation code here
	If($(“input[type=’radio’]:checked”).length == 0)
	{
            alert(‘No radio button selected’);
            return false;
        }
        else
        {
	    // ooBCoreInvoke function here to save form
	    ooBCoreInvoke(action, target);
        }
    }
}
  • This way you can have publishing page validation using JavaScript.
