Hallo all. I got a javascript object with some propeties let's say
function Animal() {
this.id;
this.name;
I need to call id function in a dynamic way to get and set its value: something like this
Animal animal = new Animal();
var propertyName = "id";
animal.+propertyName = "name";
Is there an elegant way to do it? With jQuery?
Kind regards
Massimo
Apart from object syntax, in JavaScript you can also use an array-like syntax to query object properties. So in your case:
function Animal() { this.id; this.name };
Animal animal = new Animal();
animal.id = "testId";
var propertyName = "id";
alert(animal[propertyName]); // this should alert the value "testId";
Here's an article with more details: http://www.quirksmode.org/js/associative.html
No jQuery needed for this. You need to use square brackets:
animal[propertyName] = "name";
