如下面定义了名片正面的浏览，能否通过javascript文件来打开AllowDelete和Incremental属性，并修改AllowAdd为true

With wb.AddInputGroup("form1","ipg1","名片正面") \'文件上传
                    With .AddUploader("名片正面","",True)
                        \'.AllowDelete = True \'允许删除
                        \'.Incremental = False \'允许重复选择文件或连续拍照
                        .AllowAdd = False \'关闭文件上传功能
                        .AddImage("./images/" & mpzmn)
                    End With
                End With
做了一个查看详情页面，想直接在这个页面中通过按钮来调用javascript文件，打开可修改的功能，修改后保存，直接开一个新编辑页面，图片传来传去的，感觉流量太浪费了。

不可以，设置的属性不同，生成的html代码不同的。你可以都设置成true的方式（可以编辑的方式），然后用js控制隐藏/显示某一些元素。

With .AddUploader("名片正面","",True)
                        .AllowDelete = True \'允许删除
                        .Incremental = False \'允许重复选择文件或连续拍照
                        .AllowAdd = True \'关闭文件上传功能
                        .AddImage("./images/" & mpzmn)
                    End With
哪如果刚开始这样建了上传图，在刚打开时，JS怎么控制不显示上传按钮和删除按钮哪？

删除按钮隐藏后，JS怎么不能再显示回来啊？

 document.getElementById("名片正面").parentNode.style.display = "block";
 document.getElementById("名片正面_gallery.children[1].children[0].children[0]").style.display = "block";   这里出错
 document.getElementById("名片反面").parentNode.style.display = "block";
 document.getElementById("名片反面_gallery.children[1].children[0].children[0]").style.display = "block";   这里出错
 document.getElementById("btn2").style.display="block";  
 document.getElementById("btn1").style.display="block"; 
 document.getElementById("btnedit").style.display="none";

我测试没问题

Select Case e.Path
    Case "test.htm", ""
        Dim wb As New weui
        wb.AddForm("","form1","123.htm?test=123abc") \'指定接收表单数据的的页面为handle.htm
        With wb.AddInputGroup("form1","ipg1","客户资料")
            .AddInput("姓名","姓名","text").value = "舒淇"
            .AddInput("地点","地点","text").Value = "蒙古草原"
            .AddInput("日期","日期","date").value = #10/12/2012#
            With .AddUploader("up1","",True)
                .AllowDelete = True \'允许删除
                .Incremental = False \'允许重复选择文件或连续拍照
                .AllowAdd = True \'关闭文件上传功能
                .AddImage("./images/001.jpg")
                .AddImage("./images/002.jpg")
                .AddImage("./images/003.jpg")
            End With
        End With
        With wb.AddButtonGroup("form1","btg1",True)
            .Add("btn1", "确定", "button").Attribute = "onclick=""up1_gallery.children[1].children[0].children[0].style.display=\'block\'"""
        End With
        wb.AppendHTML("<script>up1.parentNode.style.display=\'none\';up1_gallery.children[1].children[0].children[0].style.display=\'none\'</script>")
        e.WriteString(wb.Build)
End Select

你的代码要改成类似

document.getElementById("名片正面_gallery").children[1].children[0].children[0].style.display = "block";  

取消文本框的只读属性怎么没有用哪？也不提示错误，就是没有改变只读。

function xgzt(){
 document.getElementById("名片正面").parentNode.style.display = "block";
 document.getElementById("名片正面_gallery").children[1].children[0].children[0].style.display = "block";
 document.getElementById("名片反面").parentNode.style.display = "block";
 document.getElementById("名片反面_gallery").children[1].children[0].children[0].style.display = "block";
 document.getElementById("btn2").style.display="block";  
 document.getElementById("btn1").style.display="block"; 
 document.getElementById("btnedit").style.display="none";
 document.getElementById("company").readonly=false;
 document.getElementById("na").readonly=false;
 document.getElementById("job").readonly=false;
 document.getElementById("mobile").readonly=false;
 document.getElementById("fax").readonly=false;
 document.getElementById("tel").readonly=false;
 document.getElementById("mail").readonly=false;
 document.getElementById("url").readonly=false;
 document.getElementById("addr").readonly=false;
 document.getElementById("bz").readonly=false;
}
