我有文件上载控制。 I m 利用控制选择图像并在数据库中予以保存。 在编辑过程中,我需要把图像放在文件上载控制的文本箱中。 是否可能? 如果是,我怎么能做到这一点?

无,不可能为<代码><input category=“file”/>要素确定初步数值。 造成这种限制的原因(由浏览器执行,而不是由协会执行)。 NET是安全。 3. 审议恶意网站所有人以下列形式造成的后果:
<input category=“file” Value=“c:anksecret.key”/>
然而,我确信,在你描述的情景中,这一限制确实是一个问题。 有了<代码><input category=“file”> 预填入图像文档(on the服务器)的道路,不大可能帮助任何途径,因为在档案领域选定的数值被用于在客户<><>><>>>/em>上查找文档,该文档将作为背书的一部分上载。
相反,考虑以显示目前形象的方式(可能是一种umb)构造其ed形形式,并加上<代码><投入类型=“file”> 载到overwrite的新形象的田地。 现有的检查箱和检查箱允许用户消除目前的形象(如果允许这样做)。
从服务器上建立一个客户档案毫无意义。 它就像监狱破碎或某种注射。
