包括阿贾克斯成功函数变量$

Question

我想，当阿贾克斯做是为了返回图像，但我不知道如何在回应中包含一个会话变量，这是我的代码：

$(document).ready(function(){ 
    $("#process").click(function(){ 

     $.ajax({ 
     type: 'POST', 
     url: 'process.php', 
     success: function (msg) { 
      $('#new-image').html('<img src="uploads/img/$_SESSION["sess_img"];" class="img-upload" alt="new image">') 
     } 
     }); 
    }); 
}); 

然后，我想展现DIV #new-image

Answer 1

可以呼应的是图像文件名中process.php这样内的图像$_SESSION["sess_img"];：

<?php 
// using time() as the cache buster, the image will never be cache by the browser 
// to solve it, you need to add condition that will check if the image has change or not. 
// or maybe you need to change the filename if it changes without adding a cache buster. 
echo $_SESSION['sess_img_chofer']."?v=".time(); 

而在你的JavaScript代码：

$(document).ready(function(){ 
    $("#process").click(function(){ 

    $.ajax({ 
     type: 'POST', 
     url: 'process.php', 
     success: function (image) { 
     $('#new-image').html($('<img>').attr('src', 'uploads/img/' + image).attr('class', 'img-upload')); 
     } 
    }); 
    }); 
});
