To allow attachments of specific file type only - Eg: Allow only image attachment

[Snehal2]

Hi Guys,

The following script will allow only image attachments(.jpg, .jpeg, .png) on the service catalog.

>>onSubmit catalog client script:

function onSubmit() {
try
{
//for non-portal
var sysid =g_form.getElement('sysparm_item_guid').value;
var rowcount=0;
var attachment = new GlideRecord("sys_attachment");
attachment.addQuery("table_name", "sc_cart_item");
attachment.addQuery("table_sys_id", sysid);
attachment.query();
while (attachment.next()) {
rowcount++;
}

if(rowcount==0){ // Missing {}
alert("Please attach Image for submitting this request(.jpg/.jpeg/png format)!");
return false; 
}
if(rowcount == 1 && (attachment.content_type.indexOf("jpg") != -1 || attachment.content_type.indexOf("jpeg") != -1 || attachment.content_type.indexOf("png") != -1)){
//alert(attachment.content_type.indexOf("jpg") + ' ,'+attachment.content_type.indexOf("jpg")+'...'+' ,'+attachment.content_type.indexOf("jpg")+ value);
return true; 
}
else
{
	alert("Attachment should be in only .jpg/.jpeg/png format!");
	return false;
}

}

catch(e)
{ 
//for-portal
if(this.document.getElementsByClassName('get-attachment').length ==1) 
{
	var value = (this.document.getElementsByClassName('get-attachment')[0].innerHTML).toLowerCase();
	//alert(value.indexOf('jpg') + ' ,'+value.indexOf('jpeg')+'...'+' ,'+value.indexOf('png')+ value);
	if(this.document.getElementsByClassName('get-attachment').length <1)
	{
	alert( "Please attach Image for submitting this request(.jpg/.jpeg/png)!");
	return false;
	}
	else if ((value.indexOf('jpg') != -1 || value.indexOf('jpeg')  != -1 || value.indexOf('png')  != -1))
	{
	return true;
	} 	 
	else
	{
	alert ("Attachment should be in only .jpg/.jpeg/png format!"); 
	return false;
	}
}
}
}

This works well for checking the file correct file type is attached when the Portal settings Mandatory attachment box is checked, however I can't get it to work where Portal settings Mandatory attachment box is not checked and there are no attachments. I have a requirement where attachments are only mandatory for certain form field selections
