whenever you need to access dynamic property you have to use square bracket for accessing property .
Syntax: object[propery}
var attributes = {
entityData: {
Party: 12
},
entityType: "Party"
};
alert(attributes.entityData[attributes.entityType]);
alert(attributes.entityData[attributes.entityType]);
You want something like this perhaps:
var attributes = {
entityData: {
Party: 12
},
entityType: "Party"
};
alert(attributes.entityData[attributes['entityType']]);
Use square braces instead of curly braces.
