Ajax将成功值返回-1

Question

Below is the code i'm using. When ever i use to return some value , it's returning as -1. Please tell me where i made the mistake or guide me what's the pbm in the code!

Javascript:

$j = jQuery.noConflict();
$j.ajax({
url:"<?php echo admin_url( 'admin-ajax.php' ); ?>",
type:"POST",
data:"action=market_place_youtube_validator&id="+code,
success:function(data){$j("#loading").hide();$j("#mine").append(data);}
});

PHP (admin-ajax.php):

function market_place_youtube_validator()
{
echo "Yes Youtube is right";
}

Answer 1

You are using PHP (echo "Yes Youtube is right";) within javascript. To return a value you would need to do return "Yes Youtube is right";
