How to pass parameters to a view

Question

I have a series of buttons which when clicked display a popup menu positioned just below the button. I want to pass the position of button to the view. How can I do that?

Answer 1

pass from other location

 new MenuView({
   collection: itemColl,
   position: this.getPosition()
})

Add an options argument to initialize in view you are getting that passed variable,

initialize: function(options) {
   // Deal with default options and then look at options.pos
   // ...
},

to get the value use -

   var v = new ItemView({ pos: this.options.positions});
