I wrote this code for a button used in a single record and it works. however I need this same procedure to work for a multi select list button. I tried all options, but cannot get my head around it. 

CODE

params = {
"FirstName" :'{!Lead.FirstName}',
"Product": "WXXXX",
"LastName": '{!Lead.LastName}',
"Email": '{!Lead.Email}',
"Telephone": '{!Lead.Phone}',
"Company": '{!Lead.Company}',
"ReceiveNewsletter": true,
"ReceiveOtherNews": true,
"IsReseller": false,
"DoNotDistribute": false,
"DoNotContact": false,
"IP": "1.1.1.255",
"REDIRECT": "https://eu2.salesforce.com/00Q/o"
};
var form = document.createElement('form');
form.setAttribute('method', 'post');
form.setAttribute('action', 'https://MY.END.POINT.URL.com');
form.setAttribute('target', '_self');

for(var key in params) {
if(params.hasOwnProperty(key)) {
var hiddenField = document.createElement('input');
hiddenField.setAttribute('type', 'hidden');
hiddenField.setAttribute('name', key);
hiddenField.setAttribute('value', params[key]);
form.appendChild(hiddenField);
}
}

document.body.appendChild(form);
form.submit();

Hi all,

I have a JavaScript List button that I want to use in Contacts related list of Account object. This button is supposed to grab and alert the user with Email addresses of contacts selected.

My code works whenever a signle record is selected, but it throws a "INVALID_QUERY_FILTER_OPERATOR" whenever multiple contact records are selected.

Need help pls.

{!RequireScript("/soap/ajax/20.0/connection.js")}

var contactRecords= {!GETRECORDIDS($ObjectType.Contact)};
var contactEmails = " ";

var ccEmails = "p4=salesforce@tionetworks.com&";

if (contactRecords.length ==0) {
alert("Please select at least one Contact record.");
} else {


var result = sforce.connection.query("select Name, Id, Email from Contact Where Id ='" +contactRecords+ "'");
var records = result.getArray("records");

for (var i=0; i< records.length; i++) {
var email = records[i].Email;
}
contactEmails += email;
alert("records:"+contactEmails);
}

Any help is appreciated.

Thank you,

Behzad
