var recipientSetInfo = new agreementsModel.RecipientSetInfo();
recipientSetInfo.setRecipientSetMemberInfos(recipientSetMemberInfos);
recipientSetInfo.setRecipientSetRole(agreementsModel.RecipientSetInfo.RecipientSetRoleEnum.SIGNER);
recipientSetInfo.setRecipientSetName("fjenning@adobe.com");
var recipientSetInfos = [];
recipientSetInfos.push(recipientSetInfo);
对此
var recipientSetInfos = [];
//Create recipient set info
for (var i = 0; i < recipientSetMemberInfos.length; i++) {
var recipientSetInfo = new agreementsModel.RecipientSetInfo();
recipientSetInfo.setRecipientSetMemberInfos(recipientSetMemberInfos[i]);
recipientSetInfo.setRecipientSetRole(agreementsModel.RecipientSetInfo.RecipientSetRoleEnum.SIGNER);
recipientSetInfo.setSigningOrder("SEQUENTIAL");
recipientSetInfo.setRecipientSetName(" Recepients");
recipientSetInfos.push(recipientSetInfo);
