Default value from select dropdown

gbenett

In Editor, I'm not sure why the following field doesn't submit "TBD" as a placeholder when the user submits (create or edit) without selecting an option. Everything else is working; I just want a default value when the required data is currently unknown.

fields: [..., {
                        label: "Db Name:",
                        name: "CurrentDbName",
                        type: "select",
                        placeholder: "Select from DBs on Host:",
                        placeholderDisabled: false,
                        placeholderValue: "TBD"
          },
]

What version of Editor are you using? Can you five me a link to the page showing the error so I can debug it?

Thanks,
Allan

Using Editor 1.5.6 (latest). Can't readily simulate the app outside our firewall -- maybe this is enough? Debug info at http://debug.datatables.net/atodox

The relevant table is #mainTable; relevant row code begins around line 407:

                                "host": "-- Previously seen object. Not included due to circular reference possibility --",

Embarrassingly, that's a bug in Editor 1.5.6 I'm afraid! It is just completely ignoring the placeholder value because of how the value is read from the select element (Editor stores the value on a property of the element to allow for strict type checking).

To patch a local copy against this issue open dataTables.editor.js in your Editor and find:

            elOpts[0].hidden = disabled; // can't be hidden if not disabled!
            elOpts[0].disabled = disabled;

Immediately after those two lines add:

elOpts[0]._editor_val = conf.placeholderValue !== undefined ?
    conf.placeholderValue :
'';

I'll have that fix in the next release! Thanks very much for letting me know about this and my apologies for the issue.

Great answer, as usual. Works like a charm.
