Forms Designer Forum

I struggle to get login name from a single value people field into a variable using js.
Here are a number of alternatives that I've tried, but none of them return anything.
// Alternative 1
var ansatt = fd.field('Ansatt').value().dictionaryEntries[0].AccountName;

// Alternative 2
var ansatt = fd.field('Ansatt').value()[0].DisplayText;

// Alternative 3
fd.field('Ansatt').control('ready', function() {
alert(fd.field('Ansatt').value()[0].DisplayText);
});

// Alternative 4
fd.field('Ansatt').control('ready', function() {
var selectedUsers = fd.field('Ansatt').value();
for (var i = 0; i < selectedUsers.length; i++) {
alert('Login: ' + selectedUsers.Key);
}
});

This one works, but returns the user display name
var ansatt = fd.field('Ansatt').value();

I need to get the login info in order to decide if this is current user or not.
(var currentuser = user.get_loginName();)

Any help on how to build the code to pull login info from a people field is appreciated.
Thanks

NB! This is SharePoint Online.

Dear Geir,
Try code like this to get an email of the selected user: You can also use this code to get the current user's email:

Thanks for responding.
Sorry to say I cannot get any information from your suggested code either.
Here is the complete JS script in my form:
function setFieldProperty() {
var ansatt = fd.field('Ansatt').value();
alert("-->" + ansatt);
var ansatt2 = fd.field('Ansatt').value()[0].EntityData.Email;
alert("-->" + ansatt2);
}
// Calling setFieldProperty on form loading
setFieldProperty();

The first alert displays user display name from the Ansatt-field, but the second does not display anything.
It seems that the script stops/fails when trying to assign a value from the Ansatt-field.
Not even the static text in the alert is displayed.

Am I building the script wrong?

Dear Geir,
First of all, what does the browser's console say? Are there any errors? If there are, what are they, can you show?

Also, you can always experiment by typing commands in the console directly, so you don't need to save the form and wait for it to load, just open the form, open the console and start typing different commands to see what is returned. I didn't see an assignment in your code, so I assume fd.field('Ansatt').value()[0].EntityData.Email didn't work.

Try to run these commands from console one by one: Finally, it's also important what template you have selected in Forms Designer for People picker? Is it default or SP2010? Default is preferable in this case.

Thanks for the tips.
First: Template = Default
There are errors in the console:

Dear Geir,
What form are you working with? Is it the Display Form? Or maybe the field Ansatt is set to readonly in editor?

I need to get value from Ansatt-field in both Display and Edit form.
The script in previous post was from the Display form.

This is the current script from the Edit form:
SP.SOD.executeOrDelayUntilScriptLoaded((function() {
var ctx = new SP.ClientContext.get_current();
var web = ctx.get_web();
ctx.load(web);
var user = web.get_currentUser();
user.retrieve();

ctx.executeQueryAsync(function() {
var currentuser = user.get_loginName();
var currentuser = currentuser.slice(18);
var ansatt = fd.field('Ansatt').value()[0].EntityData.Email;
if(currentuser == ansatt){
alert('equal');
}else{
alert('not equal');
}
});
}), "SP.js");

Console displays this error message:

BUT:
When entering this cmd directly in the console it now returns the correct value: fd.field('Ansatt').value()[0].EntityData.Email;

Field "Ansatt" is set to ReadOnly=False
Is this a requirement for getting field value?

Dear Geir,
First of all, I would really recommend to comment out the request code and all the code that is not used to retrieve an email, it just adds complication and right now we just need to get email consistently.

The issue with the code in Edit Form currently is the fact that the field hasn't finished loading when you try to access it. Try to add this code to JavaScript editor on the form instead (Edit Form): I don't think there is an easy way to get an email from People picker field on Display Form, though. It's just a text control, it doesn't store additional information.

This worked fine.
Thanks for excellent help.
