在Jquery AJAX中显示PHP数据 [英] Display PHP data in Jquery AJAX

问题描述

我有一个php页面，其中用单选按钮显示一些图像.首先，预先选择两张图片，然后将它们合并并显示组合.但是用户可以选择其他图像，然后单击MergeImages按钮，该按钮应显示所选的两个图像的组合.

I have a php page where I display few images with radio buttons. On start two images are pre selected and I merge those and show the combinations. But user can choose a different image and click on MergeImages button, which should display the combination of two images selected.

我在一个php文件中执行此操作，在该文件中，我通过POST将所选内容通过AJAX传递到同一文件.

I am doing this in one php file, where I pass the selected contents via POST to the same file through AJAX.

$.ajax({
          url: 'CreateImage.php',
          type: 'POST',
          data: {imagename : newImageName},
          success: function(data) {
          },
          error: function(jqXHR, textStatus, errorThrown) {
            console.log(textStatus, errorThrown);
          }
    });

我获得了成功，现在我想显示数据，以便可以看到新创建的图像.我该怎么做?

I am getting a success and now I would like to display the data so that I can see the newly created images. How do I do this?

推荐答案

如果要在DIV中显示数据，可以执行以下操作:

If you want to display the data in a DIV, you can do this:

html:

<div id="myemptydiv"></div>

javascript:

javascript:

$("#myemptydiv").append(data);

php(如果您在同一个文件中，则必须清除缓冲区1st，但应将另一个php文件用于ajax请求):

php (if you are in the same file, you have to clear the buffer 1st but you should use another php file for ajax requests instead):

<?php 
if(isset($_POST['imagename'])){
while(@ob_end_clean());
//do stuff here
echo $data;
exit;
}
?>
