<?php $sql = "select pic from e_user where uid = '1dff5b51f862e6d181577e3ca34248be'"; $js = get_js_object($sql); Header( "Content-type: image/png"); echo $js->pic; echo '<p><img src="/static/imghw/default1.png" data-src="../php/testlist.php" class="lazy" style="max-width:90%" alt="php如何获取数据库中blob,然后将他显示到datagrid中" ></p>'; ?>
<table class="easyui-dategrid" url="../php/testlist.php"> <thead> <tr> <th field="pic" width="120">图片</th> </tr> </thead></table>
如何修改?

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。
