Jquery concatenation ?

[gautamz07]

$('#gallery a').click(function(evt){
evt.preventDefault();
var imgPath = $(this).attr('href');
var oldImage = $('#photo img');
var newImage = $('<img src="' + imgPath + '">');
newImage.hide();
$('#photo').prepend(newImage);
newImage.fadeIn(1000);
oldImage.fadeOut(1000,function(){
    $(this).remove();
    }); //end Fadeout
    });//end click    
    $('#gallery a:first').click();
}); // end ready
 

How does the concatination on line 5 really work and what is it really doing , i understand that its appending 'imagePath' .. but how exactly is it doing it ? and what are all this " ' for , i mean so many of them

and what are all this " ' for , i mean so many of them

attribute values should be quoted and must be quoted if the attribute value contains whitespace. hence the need to put quote marks inside the quote mark delimited strings.

i understand that its appending 'imagePath' .. but how exactly is it doing it ?

plain old string concatenation?

thank you sir , but i still did't understand what exactly is the single quotation for and the double quotation for ! even though u say its the same old concatination !!!

[Dormilich]

hm, let me put it this way: how would you print a quote mark?

[gautamz07]

in javascript if i have to print out a string along with a value , u concatinate it like this :

var a= 3;
console.log("the value of a is " + a + "and you will see this printed to the console");
