Sign Up with button or hyperlink click RRS feed

  • Question

  • I have a list of items with a lookup column for a single individual. How might I create a button or hyperlink column to allow a user to "sign up" or "un-sign up" for each event item and thus change the lookup column to [Me] to in affect assign them to that item? Thanks!

  • Hi ste854,

    According to your description, you might want to update the look up field to current logged in user for each item when clicking a button or a hyperlink to achieve the function similiar with "Sign Up" action.

    What's the field type ? A normal look up field or a Person field ?

    If the field is a lookup field, you can create a button and then update the field value like the code snippet below:

     var PetkaLookupSingle = new SP.FieldLookupValue();  
       oListItem.set_item('PetkaLookup', PetkaLookupSingle);  

    If the field type is a Person field, you can update the field value like the code snippet below:

    var singleUser = SP.FieldUserValue.fromUser('Peter Dotsenko');  
       oListItem.set_item('PetkaPersonSingle', singleUser);
