Question

追加它的來源我有很多圖片的標籤，看起來像下面

<img class="vCSS_img_alternate_product_photo" id="alternate_product_photo_6" style="border-color:#666666;" src="/v/vspfiles/photos/ChiWahGuitar-6S.jpg" border="1" onmouseover='javascript:change_product_photo(6);return false;'> 

使用jQuery我想要做的是找到所有源（SRC標籤）類名爲vCSS_img_alternate_product_photo與http://www.mydomain.com

所以在上面的例子中追加SRC的圖片src將http://www.mydomain.com/v/vspfiles/photos/ChiWahGuitar-6S.jpg

或者這將是

<img class="vCSS_img_alternate_product_photo" id="alternate_product_photo_6" style="border-color:#666666;" src="http://www.mydomain.com/v/vspfiles/photos/ChiWahGuitar-6S.jpg" border="1" onmouseover='javascript:change_product_photo(6);return false;'> 

Answer 1

是否這樣？

$('.vCSS_img_alternate_product_photo').each(function() { 
    $(this).attr('src', 'http://www.mydomain.com' + $(this).attr('src')); 
}); 

Answer 2

$(document).ready(function(){ 
    $(".vCSS_img_alternate_product_photo").each(function(){ 
     var current_src = $(this).attr("src"); 
     var new_src = "http://www.mydomain.com/"+current_src; 

     $(this).attr("src",new_src); 
    }); 
})
