Getting Sibling Value Of Key In A Javascript Object Literal
Does anybody know of there's a way to reference the value of a sibling key in a JavaScript object literal? so use the value of target in the beforeNext() function here: obj: {
Solution 1:
This is not a "JSON" object, but a JavaScript Object (or just "Object"). I assume that this is also contained in an Object literal as obj: {
by itself is invalid syntax.
Anyway, yes you can reference properties of an object in methods with this
.
beforeNext: function () {
this.target;
}

Solution 2:
In case you're dealing with plain JavaScript:
var cartoon = {"george jetson":{"son":"elroy","daughter":"judy"} }
Use the Object constructor to convert a string to an object:
cartoon["george jetson"].son = Object(cartoon["george jetson"].son)
Then bind the sibling value:
cartoon["george jetson"].son.sister = cartoon["george jetson"].daughter
And use toString
to get the original value:
cartoon["george jetson"].son.toString()
