I need to get the value of a lookup control on a display form and store it in a variable. I was thinking I could use SPServices to accomplish this, but (unfortunately) I don't have much experience with it.

I also need to do the same on the edit form, but also recapture the value if it changes.

Any pointers would be greatly appreciated.

  • Just use javascript to get the value of the element containing the field value. jQuery may make this easier if you're new to JS. – wjervis Mar 17 '18 at 20:34
  • What are you going to do with the value stored in a variable? Can you give us a few more details about your project? – Mike Smith - MCT - MVP Mar 17 '18 at 22:54
  • I’m planning to create a cookie and pass the variable to it. The cookie will be used to pass the value to a hidden field in another form. In theory, this hidden field will be used to filter a lookup in this second form via spservices. – Jonathon Carrell Mar 17 '18 at 23:56
  • The big picture goal is to filter a lookup in a child form based on a lookup value in the parent form. There is a relationship between the parent and child lookups that I’m hoping to leverage as a filter. – Jonathon Carrell Mar 17 '18 at 23:58
  • You probably want to use SPUtility.js not SPServices.js. github.com/kitmenke/sputility/blob/master/README.md – mannaggia Mar 18 '18 at 1:20

I was able to store the parent lookup value and pass it to a new cookie using the following ... Thanks for suggesting SPUtility.js!

Now for the next step!
