To get Attachment details by using java script in d365

In Dynamics 365 CRM, To retrieve the attachments field name,type and Url by using javascript

Step 1: 
function GetName(executioncontext) 

{

var formcontext=executioncontext.getFormComtect();

var file= formcontext.getAttribute("new_attachment").getValue();

var view=file.fileUrl;

var attachment=file.fileName;

var attachments=file.mimtype;

var attach=attachments.split('/')[0];

if( attach== "image")

{

formcontext.getAttribute("new_attachmenttype").setValue("Image");

}

if( attach== "application")

{

formcontext.getAttribute("new_attachmenttype").setValue("Document");

}

if( attach== "video")

{

formcontext.getAttribute("new_attachmenttype").setValue("Video");

}

if( attach== "text")

{

formcontext.getAttribute("new_attachmenttype").setValue("Document");

}

}

Step 2: To get name and file type.

var attachments=file.mimtype;

We can get the file type.

Step 3: To get Url

var view=file.fileUrl;

Step 4: To split the file type.  I have used split.

var file= formcontext.getAttribute("new_attachment").getValue();

var attachments=file.mimtype;

var attach=attachments.split('/')[0];
