computeData

function

`scope.computeData(key)`

Parameters

key {can-mustache.key}:
A dot seperated path. Use "." if you have a property name that includes a dot.
options {can-view-scope.readOptions}:
Options that configure how the key gets read.

Returns

{Object}:

An object with the following values:

Use

scope.computeData(key, options) is used heavily by [can-mustache] to get the value of a [can-mustache.key key] value in a template. Configure how it reads values in the scope and what values it returns with the [can-view-scope.readOptions options] argument.

var context = new Map({
  name: {first: "Curtis"}
})
var scope = new Scope(context)
var computeData = scope.computeData("name.first");

computeData.scope === scope //-> true
computeData.initialValue    //-> "Curtis"
computeData.compute()       //-> "Curtis"

The compute value is writable. For example:

computeData.compute("Andy")
context.attr("name.first") //-> "Andy"
