图片数据流只能用 img 标记接收
即由 ../php/testlist.php 输出

我想问一下,我现在已经可以获取到图片了。
我想在html 页面 选中 datagrid中某一行获取id后,点击按钮,弹出一个框。 框里面显示图片。
这个图片如何根据获取到的id进行查询。

这个src 可以动态赋值吗?
不知道你的弹框具体是如何实现

我看过一次这种写法,好像是在输出验证码的时候,传值是肯定可以的。
其实html页面加载时就会自动按照src中的地址向服务器请求图片,你如果提供一个php地址的话,只要在php里输出图片流就可以了。传值的话就是再php里get接收后获取对应图片资源然后打印到页面上就可以了。
