No way to set property by .prop() method with value which is a function

Sometime you need to define object where it's property names comes only in runtime.

var dynamicPropertyName = getDynamicPropertyName();
var obj = {};
obj[dynamicPropertyName] = 'value';

However it's too verbose and cannot be inlined.

jQuery 1.6 method .prop() can help

var obj = $({}).prop(dynamicPropertyName, 'value')[0];

But if value is a function this approach will not work

obj[dynamicPropertyName] = function() {alert('value');} ;


var obj = $({}).prop(dynamicPropertyName, function() {alert('value');})[0];

It will not work because the function will be executed instead of just setting value.

I think there should be some parameter to disable function execution if needed.

See for more details

This is pretty rare. You can either assign the property to the DOM element directly as you did above, or have your function argument to .prop return a function.
