Beginner Error - Problem with javascript to learn

Posted on by Community Member

I am starting in script development, I am performing some test for learning based on microsoft documentation. I am writing an opportunity script to:
- Display a message when a form is loaded
- Assign description text for when a field has its content changed
- Display a message when saved

I tried several ways to run the code, but always get an error message. Can anybody help me?

_________________________________________________________

// A namespace defined for the sample code

// As a best practice, you should always define

// a unique namespace for your libraries

var Sdk = window.Sdk || {};

(function () {

// Define some global variables

var myUniqueId = "_myUniqueId"; // Define an ID for the notification

var currentUserName = Xrm.Utility.getGlobalContext().userSettings.userName; // get current user name

var message = currentUserName + ": Your JavaScript code in action!";

// Code to run in the form OnLoad event

this.formOnLoad = function (executionContext) {

var formContext = executionContext();

// display the form level notification as an INFO

formContext.ui.setFormNotification(message, "INFO", myUniqueId);

// Wait for 5 seconds before clearing the notification

window.setTimeout(function () { formContext.ui.clearFormNotification(myUniqueId); }, 5000);

}

// Code to run in the attribute OnChange event

this.attributeOnChange = function (executionContext) {

var formContext = executionContext();

// Automatically set some field values if the account name contains "Contoso"

var Name = formContext.getAttribute("name").getValue();

if (Name.toLowerCase().search("contoso") != -1) {

formContext.getAttribute("description").setValue("">https://www.contoso.com");

}

// Code to run in the form OnSave event

this.formOnSave = function () {

// Display an alert dialog

Xrm.Navigation.openAlertDialog({ text: "Record saved." });

}

}).call(Sdk);

RE: Beginner Error - Problem with javascript to learn

The code in the link in my previous post will work on Opportunity if you comment out the following 2 lines (the attributes do not exist for Opportunities, but the others in the JavaScript do)

// formContext.getAttribute("websiteurl").setValue("www.contoso.com");

// formContext.getAttribute("telephone1").setValue("425-555-0100");

(also, after you make changes to the JavaScript or the Form make sure you Publish, and sometimes when testing your changes you also need to refresh the Browser window <ctrl><f5> to force the browser to reload cached JavaScript etc).

When I use template code on an account form it works. I'm having trouble when I adapt code to run on an opportunity form.

RE: Beginner Error - Problem with javascript to learn

@Arun, he is attempting to run sample code that is similar but not 100% the same as that provided by Microsoft docs.microsoft.com/.../walkthrough-write-your-first-client-script (I don't particularly like the structure of it or the use of "window" - but it is what it is)

@Edersc, I used the code as provided by MSFT in the link above, hooked up the onLoad and it works without any errors (I didn't hook up any other events) - your original code does not 100% match that from MSFT so not sure if you have copied it from an old version or someone else - anyway try with the code from link in this message. (note, this was on the Account entity and the Account for Interactive Experience form, and accessed it from a '...…. Hub' app).

RE: Beginner Error - Problem with javascript to learn

I believe you are not calling the right method name. refer this: stackoverflow.com/.../7920473

Also as you are using ES6 standards to call using prototype, I'm not sure about it.

var formContext = executionContext();

//to

var formContext = executionContext.getFormContext(); // get formContext

RE: Beginner Error - Problem with javascript to learn

Thank you Arun for helping me!

I made the changes but the messages are still displayed. Below are the messages:

Error in custom event for this field.

Field: window

Event: onload

Error: undefined

Error in custom event for this field.

Field: crmForm

Event: onsave

Error: undefined

Error in custom event for this field.

Field: name

Event: onchange

Error: undefined

As you advised me, I already selected the field "Pass execution context with a first parameter" and updated the code. With the change follows the new code:

// A namespace defined for the sample code

// As a best practice, you should always define

// a unique namespace for your libraries

var Sdk = window.Sdk || {};

(function () {

// Define some global variables

var myUniqueId = "_myUniqueId"; // Define an ID for the notification

var currentUserName = Xrm.Utility.getGlobalContext().userSettings.userName; // get current user name

var message = currentUserName + ": Your JavaScript code in action!";

// Code to run in the form OnLoad event

this.formOnLoad = function (executionContext) {

var formContext = executionContext.getFormContext();

// display the form level notification as an INFO

formContext.ui.setFormNotification(message, "INFO", myUniqueId);

// Wait for 5 seconds before clearing the notification

window.setTimeout(function () { formContext.ui.clearFormNotification(myUniqueId); }, 5000);

}

// Code to run in the attribute OnChange event

this.attributeOnChange = function (executionContext) {

var formContext = executionContext.getFormContext();

// Automatically set some field values if the account name contains "Contoso"

var Name = formContext.getAttribute("name").getValue();

if (Name.toLowerCase().search("contoso") != -1) {

formContext.getAttribute("description").setValue("www.contoso.com");

}

}

// Code to run in the form OnSave event

this.formOnSave = function () {

// Display an alert dialog

Xrm.Navigation.openAlertDialog({ text: "Record saved." });

}

}).call(Sdk);

Regards,

RE: Beginner Error - Problem with javascript to learn

You haven't shared the error message to understand the issue.

Couple of things to troubleshoot further:

1. Make sure you are passing the parameter by checking the "Pass execution context as first parameter" like explained in the below post

docs.microsoft.com/.../clientapi-execution-context

2. Change the below line:

//buggy code

var formContext = executionContext();

//fixed code

var formContext = executionContext.getFormContext();
