sharepoint-2013 - Sharepoint 2013 模态对话框未加载

Question

您好，我有一个简单的页面上传到 SharePoint 页面库，并试图模拟长时间运行的操作，没有关闭等待对话框。下面是我所拥有的脚本

<script type="text/javascript">
    var waitDialog = null;
    function DoWork() {
        toggleProcessingStatus(true);
        UpdateUI();
        toggleProcessingStatus(false);
    }
    function UpdateUI()
    {
        var lblControl = document.getElementById("lbl");
        for (i = 0; i < 20000; i++) 
        {            
            lblControl.innerText = lblControl.innerText + i;
        }
    }
    function toggleProcessingStatus(showStatus) {
        if (showStatus) {
            ExecuteOrDelayUntilScriptLoaded(ShowWaitDialog, "sp.js");
        }
        else {
            if (waitDialog != null) {
                //setTimeout(CloseWaitDialog, 5000);
                CloseWaitDialog();
            }
        }
    }
    function ShowWaitDialog() {
        waitDialog = SP.UI.ModalDialog.showWaitScreenWithNoClose('Updating...', 'Please wait while update completes...', 150, 330);
    }

    function CloseWaitDialog() {
        if (waitDialog != null) {
            waitDialog.close();
        }
    }
</script>
<input type="button" id="btnShowDialog" title="Do Long Running Work" name="Do Long Running Work" onclick="javascript: DoWork();" value="Do Long Running Work"/>
Label: <label id="lbl" title="Test">Test Wait Screen</label>

非常感谢任何帮助。

谢谢，马利卡君

必须加载“sp.ui.dialog.js”。

我已将以下代码添加到我想打开对话框的当前页面。
