What does this mean?

What does this code mean?  I don't understand it.

 

function onclose(func){
this.onclose_func = func;
}

[Omirion]

It seams like a code to attach dynamic methods to functions, or to assign a function to and onclose event.

 

Please post the entire code

Takes a function as a parameter and assigns it to the object's "onclose_func" property. There is very little more we can tell you about this based on that, as there is no standard "onclose_func" property. This code is completely custom written... As Omirion says, show the rest of it.
