jquery中的show（）方法不起作用(show() method in jquery not working)

jquery中的show（）方法不起作用(show() method in jquery not working)

我有以下代码。

$(document).ready(function() { var factoryImage = document.getElementById("photo"); factoryImage.src = document.getElementById('<%= FactoryImageFileNameHF.ClientID %>').value; factoryImage.show(); });

我有jquery的以下脚本源。

<script src="/Scripts/jquery-3.0.0.min.js" type="text/javascript"></script>

我收到以下错误。

jQuery.Deferred exception: factoryImage.show is not a function TypeError: factoryImage.show is not a function at HTMLDocument.<anonymous> (http://localhost:3373/Intranet/OHS/InteractiveMap/FactoryLayoutSettings.aspx:403:38) at j (http://localhost:3373/Scripts/jquery-3.0.0.min.js:2:29588) at k (http://localhost:3373/Scripts/jquery-3.0.0.min.js:2:29902) undefined

哪个就行了factoryImage.show（）;

这是图像

<img id="photo" src="/Icons/Factory Layout.png" style="display:none"/>

我可以确认jquery中的factoryImage不为null或未定义。 有一些我想念的东西，我知道这很容易，但我无法弄清楚。 为什么show方法不起作用？

I have the following code.

$(document).ready(function() { var factoryImage = document.getElementById("photo"); factoryImage.src = document.getElementById('<%= FactoryImageFileNameHF.ClientID %>').value; factoryImage.show(); });

I have the following script source for jquery.

<script src="/Scripts/jquery-3.0.0.min.js" type="text/javascript"></script>

I get the following error.

jQuery.Deferred exception: factoryImage.show is not a function TypeError: factoryImage.show is not a function at HTMLDocument.<anonymous> (http://localhost:3373/Intranet/OHS/InteractiveMap/FactoryLayoutSettings.aspx:403:38) at j (http://localhost:3373/Scripts/jquery-3.0.0.min.js:2:29588) at k (http://localhost:3373/Scripts/jquery-3.0.0.min.js:2:29902) undefined

which is right on the line factoryImage.show();

Here is the image

<img id="photo" src="/Icons/Factory Layout.png" style="display:none"/>

and I can confirm that factoryImage in the jquery is not null or undefined. There is something I am missing which I know will be easy but I can't figure it out. Why is the show method not working?

最满意答案

问题是factoryImage不是jQuery元素而是DOM元素，这应该可行

$(document).ready(function () { var factoryImage = $("#photo"); factoryImage.attr("src", document.getElementById('<%= FactoryImageFileNameHF.ClientID %>').value); factoryImage.show(); });

The problem is that factoryImage is not a jQuery element but a DOM element, this should work

$(document).ready(function () { var factoryImage = $("#photo"); factoryImage.attr("src", document.getElementById('<%= FactoryImageFileNameHF.ClientID %>').value); factoryImage.show(); });
