javascript - CSS样式{显示:none} is not working in htmlattribute

Question

我在 TextBoxFor 调用中使用了 CSS 样式 display: none，但它不起作用。

<img id="Img" src="~/abc/def.jpg" style="height: 120px; max-width: 100%; width: 280px;" class="img-responsive" />
@Html.TextBoxFor(m => m.dP,  new { htmlAttributes = new { @class = "form-control has-feedback-left file btntag", @onchange = "openFile(event)", @style="display: none;", @type="file", placeholder = "Upload Display Picture" } })
@Html.ValidationMessageFor(model => model.dP, "", new { @class = "text-danger" })

Answer 1

<img id="Img" src="~/abc/def.jpg" style="height: 120px; max-width: 100%; width: 280px;" class="img-responsive" />
@Html.TextBoxFor(m => m.dP,  new { @class = "form-control has-feedback-left file btntag", onchange = "openFile(event)", style="display: none;", @type="file", placeholder = "Upload Display Picture" } )
@Html.ValidationMessageFor(model => model.dP, "", new { @class = "text-danger" })

以上是为助手定义 html 属性的正确方法。 (删除多余的“htmlAttributes = new”部分。)
