jQuery plus sign

[terryds]

$("p:first").data("test","This is some data.");var p = $("p:first").detach();console.log("Data stored: "+p.data("test"));

 

 

What does the "+p.data("test"))" mean ?

The plus sign in Javascript (jQuery as well I'm sure) means to concatenate. Like how the dot in PHP is to concatenate, in JavaScript the plus sign is for that.

 

The above would output: "Date stored: This is some data" I believe(not too familiar with jQuery).

it is a Javascript operator that will either concatenate or add, depending on the context.
