Initialize word document content type properties using Javascript

Question

I'm trying to create a new word document from a template using the following javascript code :

var word = new ActiveXObject("Word.Application"); var doc = word.Documents.Add("/server/docLib/ContentType/template.dotx");

before i display the word application, i want to initialize some content types properties :

doc.ContentTypeProperties.GetItemByInternalName("field1_internalName").Value = "MyValue"

The previous code works fine. But when I try to set a property of type Lookup, an exception is raised with no error description.

To see what was wrong, i used the following code to open an existing document with all properties filled.

var word = new ActiveXObject("Word.Application"); var doc = word.Documents.Open("/server/docLib/doc1.docx"); var ct = doc.ContentTypeProperties; var lookupprop = ct.GetItemByInternalName("field1_internalName");

After debugging, I found that lookupprop is an object of type MetaProperty and contains somme fields like Type, ID... etc. and Value of type Variant. when i tried to acces the value, the same exception was raised.

My question is : Is it possible to set a lookup properties like this? and if yes how?

Lookup columns are special and require special interaction, please read this excerpt from MSDN:

 function addNewSale(employeeId, salesachieved, customer, description) { // Get the current context var context = new SP.ClientContext.get_current(); // Get the web var web = context.get_web(); // Get the Sales list var list = web.get_lists().getByTitle('Sales'); // create the ListItemInformational object var listItemInfo = new SP.ListItemCreationInformation(); // add the item to the list var listItem = list.addItem(listItemInfo); // Assign Values for fields listItem.set_item('SalesAchieved', salesachieved); listItem.set_item('Customer', customer); listItem.set_item('Title', description); //Lookup field need to be catered using FieldLookUp value var employeeNameValue = new SP.FieldLookupValue(); employeeNameValue.set_lookupId(employeeId); listItem.set_item('EmployeeName', employeeNameValue); // Adding value for a Date Field var currDate = new Date(); listItem.set_item('SaleDate', currDate); listItem.update(); //Make a query call to execute the above statements context.executeQueryAsync(Function.createDelegate(this, this.on_addSales_Success), Function.createDelegate(this, this.on_addSales_Failure)); } function on_addSales_Success() { alert("Sale successfully created."); } function on_addSales_Failure() { alert("Error while creating new Sales."); }

Hi Hugh, thank you for the answer. My problem here is not to update an item using Javascript, but to launch a new document command and be able to initialize some fields before opening it using Word client. As mentioned in the first post, I did that successfully for some basic fields (Text, Choice etc), but with the lookups field an exception occurs when I try access the value. — must19
