Question

我只是想证明在我的SharePoint托管的应用页面中显示模式对话框的概念。我相信我已经包含了所需的js库，并且在执行我的函数之前，我给它足够的时间来加载库。我收到的错误是：

无法读取未定义的属性'hiddenButtonValueBeforeDialog'

我相信我有我需要的库::

<script type="text/javascript" src="/_layouts/15/init.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.runtime.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.js"></script>
<script type="text/javascript" src="/_layouts/15/SP.UserProfiles.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.core.js"></script>
<script type="text/javascript" src="/_layouts/15/sp.ui.dialog.js"></script>

使用Javascript：

function showDialog() {

var optDict = {
    width: 800,
    height: 500,
    url: 'http://www.google.com',
    title: "Upload your file"
};

try {
    SP.UI.ModalDialog.showModalDialog(optDict);
}
catch (err) {
    alert(err.message);
}

    return false;
}

Answer 1

错误Cannot read property 'hiddenButtonValueBeforeDialog' of undefined发生，因为sp.ui.dialog.js是全球化的JavaScript库，并且尚未在客户端加载所需的资源文件SP.Res.resx（SP.Res.hiddenButtonValueBeforeDialog生成从这个文件）。

解决方案

ScriptResx HTTP处理程序用于加载资源的内容客户端的文件，必须添加以下行：

<script type="text/javascript" src="/_layouts/15/ScriptResx.ashx?name=sp.res&culture=en-us"></script>

此外，由于SP.UI.UIUtility存在依赖关系 sp.ui.dialog.js库中的命名空间，sp.init.js JavaScript 必须引用库：
```
<script type="text/javascript" src="/_layouts/15/sp.init.js"></script>
```

Answer 2

我在PlaceHolderMain中添加了所有这些引用

<script src="/_layouts/15/1033/init.js" type="text/javascript"></script>
<script src="/_layouts/15/MicrosoftAjax.js" type="text/javascript"></script>
<script src="/_layouts/15/ie55up.js" type="text/javascript"></script>    
<script src="/_layouts/15/sp.core.js" type="text/javascript"></script>
<script type="text/javascript" src="/_layouts/15/ScriptResx.ashx?name=sp.res&culture=en-us"></script>
<script type="text/javascript" src="/_layouts/15/sp.init.js"></script>
<script src="/_layouts/15/sp.ui.dialog.js" type="text/javascript"></script>
<script src="/_layouts/15/core.js" type="text/javascript"></script>
<script src="/_layouts/15/sp.runtime.js" type="text/javascript"></script>
<script src="/_layouts/15/sp.js" type="text/javascript"></script>
<script src="/_layouts/15/inplview.js" type="text/javascript"></script>
<script src="/_layouts/15/cui.js" type="text/javascript"></script>
<script src="/_layouts/15/sp.ribbon.js" type="text/javascript"></script>
<script src="/_layouts/15/mdn.js" type="text/javascript"></script>
<script src="/_layouts/15/sp.ui.pub.ribbon.js" type="text/javascript"></script>
<script src="/_layouts/15/msstring.js" type="text/javascript"></script>
<script src="/_layouts/15/socialdata.js" type="text/javascript"></script>
<script src="/_layouts/15/sp.ui.socialribbon.js" type="text/javascript"></script>
<script src="/_layouts/15/cui.js" type="text/javascript"></script>
<script src="/_layouts/15/wpadder.js" type="text/javascript"></script>
<script src="/_layouts/15/search.js" type="text/javascript"></script>

现在所有的javascript错误都消失了
