Get the value of one row with the ID in argument

Question

I would like to display through the script editor the Content of one row in a parent site. For each row, I have a unique value, I would like to put it as an argument. I'm not a JavaScript expert, therefore I tried to adapt some code founded on Internet but doesn't work.

Thanks in advance.

Answer 1

When using JSOM to query list items, you must include the fields you want to read in your load statement.

This would change your line

clientContext.load(collListItem);

into

clientContext.load(collListItem, "Include('Title', 'TaskName')");

where TaskName is the internal field name.

Hope this helps!

Answer 2

Rigth now, I can Display several fields with :

clientContext.load(collListItem);

and

listItemInfo += '<strong>ID: </strong> '  + oListItem.get_id() +
'<strong>ID: </strong> '  + oListItem.get_item('field1') +
'<strong>ID: </strong> '  + oListItem.get_item('field2') +

But I also want to display the "Name" of the element, I can do it with :

clientContext.load(collListItem, 'Include(DisplayName)');

and

listItemInfo += '<strong>ID: </strong> '  + oListItem.get_displayName()

I didn't find yet how to combine these two Displays...
