Hi,

I have created javascript file with the namespace pattern, code is as below...

var MyNamespace = MyNamespace || {};

MyNamespace = function (Xrm, $, undefined) // Start namespace definition

{
"use strict";

// Start of private functions
var _MyTestFunction = function ()
{
alert("Works fine....");
}

// Start of public variables and functions return object
return {

//// Start of public functions
MyTestFunction: _MyTestFunction,
//// End of public functions
}
}(window.Xrm, jQuery);

From the normal web application We call the function with the following syntax.

MyNamespace.MyTestFunction

But its not working from the CRM form. When I called it onload form event. It throws following error.

Script Error
One of the scripts for this record has caused an error. For more details, download the log file.
TypeError: Object doesn't support property or method 'MyTestFunction' at eval code (eval code:1:1)

How can we call this function from the CRM form properties? Please help me if I am missing anything.

For example:

if (typeof (YourNamespace) == 'undefined') {

window.YourNamespace = {};

}

if (typeof (YourNamespace.Functions) == 'undefined') {

window.YourNamespace.Functions = {};

}

YourNamespace.Functions.Actions= {

}

It works for me every time.

Did you ever resolve this?

I have the same issue. Seems to only effect Internet Explorer 11 (or at least only that browser throws the error message).

I feel certain I have seen namespaces used before in CRM. However the Form events seem to throw an error.

Could you try with the follwoing line to declare the namspace, we had similar issue, the old way didnt work and we had to do the following

if (typeof (MyNamespace) === 'undefined') { MyNamespace = function () { }; }

Hello,

The JS file (account entity) can be looks like this:

Var X = X || {};

Var X.Form = X.Form || {};

Var X.Form.Account = function (){

function onLoad(){

//Do whatever you need

}

function onSave(){

//Do whatever you need

}

return {

OnLoad: onLoad,

OnSave: onSave

};

}();

Once you add the JS file to your entity form, you can call now the function in your js as following: X.Form.Account.OnLoad

Hope this helps,
