what means “a word:” before define a function in javaScript?

Question

I have a javaScript sample: in this sample is used words and \":\" before define function. what is it? please help me...

Jb.prototype = {clickButton: functio         


        

Answer 1

This is an object literal with function expressions in it. Do you know about object literals?

x = {asdf: 1, fdsa: 2}

will create an object with properties asdf and fdsa set to 1 and 2 respectively. The object literal in question simply has much more complex property values.
