Zimlet cookbook based on JavaScript API

Mail

1. How to get access to an email's to,cc,bcc,subject, body information when its drag-dropped onto Zimlet's panel Item? First off we need to allow message(ZmMailMsg) or conversation(ZmConv) to be dragged onto Zimlet Panel Item.

  <zimletPanelItem label="Zimlet Name" icon="Zimlet-panelIcon">
		<dragSource type="ZmConv" />
		<dragSource type="ZmMailMsg" />
  </zimletPanelItem>

Then, within the Zimlet's Javascript file, we need to override 'doDrop' function.

com_zimbra_coloredemails.prototype.doDrop =
function(zmObject) {

};

The email dropped(zmObject) can be either a conversation or a single email. This zmObject internally has an object called 'srcObj' (source-object) and contains the real or actual Zimbra Object that was dropped. Once we get access to this, we can access all the properties and even functions.

com_zimbra_coloredemails.prototype.doDrop =
function(zmObject) {
     var msgObj = zmObject.srcObj;//get access to source-object

    //if its a conversation i.e. "ZmConv" object, get the first loaded message "ZmMailMsg" object within that.
    if (zmObject.type == "CONV") {
      msgObj  = zmObject.getFirstHotMsg();
    }

};

At this point we have a single message "ZmMailMsg" object and we can access all its properties.

Get mail subject

  var subject = msgObj.subject; //where msgObj is of type "ZmMailMsg"

Get all email address

var emailsArray =  msgObj.getEmails(); //where msgObj is of type "ZmMailMsg"

Get email addresses only in CC

var ccemails = [];//stores all email address in the email
var participants = msgObj.participants.getArray(); //where msgObj is of type "ZmMailMsg"
for(var i =0; i < participants.length; i++) {
     if(participants[i].type == AjxEmailAddress.CC) {
      ccemails.push(participants[i].address);
    }
}

 PS: Similarly you can get emails of the following types:
 AjxEmailAddress.FROM = "FROM";
 AjxEmailAddress.TO = "TO";
 AjxEmailAddress.CC = "CC";
 AjxEmailAddress.BCC = "BCC";
 AjxEmailAddress.REPLY_TO = "REPLY_TO";
 AjxEmailAddress.SENDER = "SENDER";

Get email body

var body = msgObj.getBodyContent();

Get list of attachments

var attArray =  msgObj.attachments;
 

Download Entire Email

You can download the whole email(including all its attachments). This example is from com_zimbra_emaildownloader Zimlet.

The logic is to simply get the message's id and then do a simple http GET to http://<server>/home/message.txt?fmt=tgz&id=<messageId>

com_zimbra_emaildownloader.prototype.doDrop =
function(msgObj) {
	this.srcMsgObj = msgObj.srcObj;
	if(this.srcMsgObj.type == "CONV"){
		this.srcMsgObj = this.srcMsgObj.getFirstHotMsg();
	}
	var url = [];
	var i = 0;
	var proto = location.protocol;
	var port = Number(location.port);
	url[i++] = proto;
	url[i++] = "//";
	url[i++] = location.hostname;
	if (port && ((proto == ZmSetting.PROTO_HTTP && port != ZmSetting.HTTP_DEFAULT_PORT) 
		|| (proto == ZmSetting.PROTO_HTTPS && port != ZmSetting.HTTPS_DEFAULT_PORT))) {
		url[i++] = ":";
		url[i++] = port;
	}
	url[i++] = "/home/";
	url[i++]= AjxStringUtil.urlComponentEncode(appCtxt.getActiveAccount().name);
	url[i++] = "/message.txt?fmt=tgz&id=";
	url[i++] = this.srcMsgObj.id;
	try{
		var subject = this.srcMsgObj.subject.replace(/\*/g, "").replace(/\[/g, "").replace(/\]/g, "").replace(/\</g, "").replace(/\>/g, "").replace(/\=/g, "").replace(/\+/g, "").replace(/\'/g, "").replace(/\"/g, "").replace(/\\/g, "").replace(/\//g, "").replace(/\,/g, "").replace(/\./g, "").replace(/\:/g, "").replace(/\;/g, "").replace(/ /g, "").replace(/!/g, ""); 
		if(subject.length > 16){
			subject = subject.substring(0,15);
        }
		url[i++] = "&filename=" + subject;
	} catch(e) {
	}
	var getUrl = url.join(""); 
	window.open(getUrl, "_blank");
};
