jquery checking if an image exists in a folder

Question

i am changing the source of an image using the following code:

var src = "/Content/Productimg/" + data.image +".jpg";
              $("#image").attr("src", src);

However, sometimes if data.img returns test and test.jpg does not exist in the Productimg folder a funny icon is displayed.

Is there a way i can check if the image is there before assigning the src?

For checking if image exists or not , you can do:

$.ajax({
    url:'http://yourhost/someimage.ext',
    type:'HEAD',
    error: function()
    {
        //file does not exist
    },
    success: function()
    {
        //file exists do something here
    }
});
