如何删除/隐藏文件上传按钮旁边的“未选择文件”文本?
我的 fileUpload 控件的代码:
<xp:fileUpload id="fileUpload1"
value="#{document1.Picture}"
rendered="#{javascript:document1.isEditable()}"
mimetype="image/jpeg" useUploadname="true"
accept="image/jpeg,image/gif,image/png">
<xp:eventHandler event="onchange"
submit="true" refreshMode="complete"
disableValidators="true">
</xp:eventHandler>
</xp:fileUpload>
