Question

我在asp.net中有一个文件上传控件，如下所示：

<asp:FileUpload ID="File1" runat="server" Font-Size="Small" Width="100%" />

由于某种原因，“浏览...”按钮不适用于我已应用于任何输入[type =“button”]控件的标准CSS。

如何将相同的CSS应用于该控件的“浏览”按钮？

Answer 1

试试这个

<input type="file" class="hidden" id="uploadFile"/>
<div class="button" id="uploadTrigger">Browse</div>

一些css

.hidden {
    display:none;
}
.button {
    border: 1px solid #333;
    padding: 10px;
    margin: 5px;
    background: #777;
    color: #fff;
    width:75px;
}

<强> JS

$("#uploadTrigger").click(function(){
   $("#uploadFile").click();
});

Answer 2

由于OP是关于ASP.NET的，并且接受的答案是HTML / javascript，我以为我会用ASP.NET术语回答它：

ASP.NET部分：

<asp:FileUpload ID="fileUpload" runat="server" style="display:none" /> <input type="button" value="Select your file" id="browse"></input>

JQuery，jQuery UI for .button（）部分：

$("input:button").button(); ... $("#browse").click(function () { $("#<%= fileUpload.ClientID %>").click(); });

Answer 3

aspx格式：

<div class="fileupload-group">
    <button type="button" runat="server" id="btnFileupload" class="btnFileupload btnRed">
        Select File <i class="fa fa-folder-open"></i>
        <asp:FileUpload ID="FileUpload1" runat="server" AllowMultiple="True" />
    </button>
    <input type="text" runat="server" id="txtFileuploadName" class="fileupload-name txtRight" readonly="readonly" />
</div>

和javascript

$('input[id="<%= FileUpload1.ClientID %>"]').change(function () {
    var names = [];
    var length = $(this).get(0).files.length;
    for (var i = 0; i < $(this).get(0).files.length; ++i) {
        names.push($(this).get(0).files[i].name);
    }
    if (length > 2) {
        $("#<%=txtFileuploadName.ClientID%>").attr("value", length + " selected files");
    }
    else {
        $("#<%=txtFileuploadName.ClientID%>").attr("value", names);
    }
});

和在CSS中：
