HomeBackend DevelopmentPHP TutorialDrupal中无刷新上传文件技术探讨

在web中实现无刷新上传文件目前有几种方式:
1. 使用HTML5中的FormData和fileReader实现。但是这种方式只能用于IE10之后。
2. 使用swf文件做中转。
3. 使用隐藏的iframe提交。

以上2和3其实类似。

我在Drupal 7里发现content-type为image的字段都可以实现无刷新上传。

我研究了半天不知道它是怎么做到的。我的结论是:目前可排除第一种和第二种。但是第三种我也没在HTML内发现iframe的存在。

求解!
谢谢!

百度、google一大堆无刷新上传的东西,不局限这三种吧!按你说的,你已经把那三种可能给排除了,所以...

这是Drupal7内置的功能,应该是内置的module/file/里实现的。但是对Drupal7源码不熟,有Drupal高手有研究吗?

谢谢xuyanlu,其实我是想搞明白Drupal里是怎么实现的。:)

自己找到了。
Drupal引入了jquery.form.js。

How to calculate the total number of elements in a PHP multidimensional array?How to calculate the total number of elements in a PHP multidimensional array?May 15, 2025 pm 09:00 PM

Calculating the total number of elements in a PHP multidimensional array can be done using recursive or iterative methods. 1. The recursive method counts by traversing the array and recursively processing nested arrays. 2. The iterative method uses the stack to simulate recursion to avoid depth problems. 3. The array_walk_recursive function can also be implemented, but it requires manual counting.
