如何将JS数组添加到流星自动表单输入

Question

I am using Meteor 1.1.0 and Aldeed:Autoform and I need to put values from a string array that is generated in the template's JS file into a document entry of type [String] during (or before) submit. How can I do that?

Answer 1

The solution is to add a before: hook in Autoform.hooks with an insert: function in it, which would modify the document entries ( for this to work the parameter must be defined in the schema ). Example:

AutoForm.hooks({
    'add-form': {
        before:{
            insert:function(doc){
                doc.fileId = '1234; // doc is the data from the form. 
                return doc; // .fileId is the element we try to modify
            }
        }  
    }
});
