Set value for fields using JavaScript

Posted on by MedWong

Hello guys,

This is actually can consider related to my previous thread, about Web resources for Open a new form then Save -> https://community.dynamics.com/crm/f/microsoft-dynamics-crm-forum/430042/open-create-form-and-save-instantly

But it may not necessary also.

Issue is about specifying a default value for my fields, while having this kind of script ->

function OpenAndSaveForm(executionContext) {
//Get the form context
var formContext = executionContext.getFormContext();
// Get the form type
var formType = formContext.ui.getFormType();
if(formType == 1) { //create form
try {

formContext.data.entity.save();
}
catch (e) {
Xrm.Utility.alertDialog(e.message);
}
}
}

So because I want to have a default value in my 2 fields (xyz_description and xyz_date), I was adding these to statements :

formContext.getAttribute("xyz_description").setValue("Orders");

formContext.getAttribute("xyz_date").setValue(new Date());

formContext.data.entity.save();
}
catch (e) {
Xrm.Utility.alertDialog(e.message);
}
}
}

The lines in red are my addition, but currently produces an error saying "Cannot read property 'setValue' of null"

What would be the cause of it ? Is it correct that inside those "formContext.getAttribute" is my field name ? or should be other which makes it error. ?

Kindly advice.

Thanks

Hello Necdet,

It works! So that is the actually the cause, one of the fields is not on the form. Should've realize that sooner but I missed that.

Thank you very much everyone, you all've been so great!

rgds,

Are both fields on the Form or not?

Hi,

Your code is correct. I think your registration of Javascript is wrong. Please check it. I try with the same code and same field and it is working.

Yes, it always give me the error "Cannot read property 'setValue' of null.

But if I remove those 2 lines, the error is disappeared and the form open (and save) as intended, only for those fields are empty.

Thanks

RE: Set value for fields using JavaScript

hhmm... that actually my first tried. the "xyz_description" which I type on the first thread is actually "jm_description"

So like this in actual :

function OpenAndSaveForm(executionContext) {

//Get the form context

var formContext = executionContext.getFormContext();

// Get the form type

var formType = formContext.ui.getFormType();

if(formType == 1) { //create form

try {

formContext.getAttribute("jm_description").setValue("Orders");

formContext.getAttribute("jm_date").setValue(new Date());

formContext.data.entity.save();

}

catch (e) {

Xrm.Utility.alertDialog(e.message);

}

}

}

Thanks

Hmmm.. thanks,

So in my understanding, this schema name is related to database, and it can be changed during creation only, am I right to say that?

However, I tried to used the same but still an error.

Isn't right to say that in the Table - Tab Columns, where you usually have grid for "Display name" - "Name", then the schema name you can reach by clicking the column (field) ?

So if I have something like this :

when I click "Description", then it will pop up a window ->

The highlighted is the schema name ?

Thanks

Please refer to this blog for more details about field's naming (Display Name, Schema Name and Logicial Name) : taagung.com/.../

For your code, I believe you need to use "formContext.getAttribute('description').setValue(value)"

Hi,

Will try that, although actually I didn't use Chrome when customize this, I'm using Edge. And gonna be another journey to learn how to use that extension.

However before that, what is exactly schema name ? is that the "xyz" ? and I believe I did use bracket.

Thanks,
