Api JavaScript samples in Alfresco

Alfresco allows us to perform actions when an event occurs, such as content creation, modification, and so on. Here are some examples of use:

Js that sent mails:

  // create mail action
  var mail = actions.create("mail");
  mail.parameters.to = "user@mail.com";
  mail.parameters.subject = "News Letter Title";
  mail.parameters.from = "alfresco@society.com";
  mail.parameters.template = search.findNode("workspace://SpacesStore/9c74d256-ff43-4437-rio5-3098c54fbc7a");
  mail.parameters.text = "Sorry, but the news letter is not available this week due to maintenance needs. Please apologize for disturbance";
  // execute action against a document
  mail.execute(document);

Js that start and advanced pooled workflow:

  var workflow = actions.create("start-workflow");
  workflow.parameters.workflowName = "jbpm$wf:reviewpooled";
  workflow.parameters["bpm:workflowDescription"] = document.name;
  workflow.parameters["bpm:groupAssignee"] = people.getGroup("GROUP_myGroup");
  var futureDate = new Date();
  futureDate.setDate(futureDate.getDate() + 7);
  workflow.parameters["bpm:workflowDueDate"] = futureDate;
  workflow.execute(document);

Js that change the name of an inbound document:

  // change the name of this document
  document.properties.name = "Backup of " + document.properties.name;
  // add a new property string
  document.properties["cm:locale"] = mylocalenode;
  // save the property modifications
  document.save();
