Linkbutton打開一個模式彈出窗口，但其彈出窗口立即關閉

我正在創建一個需要在模態彈出窗口中打開一個可配置頁面的asp鏈接按鈕。Linkbutton打開一個模式彈出窗口，但其彈出窗口立即關閉

打開模式彈出窗口，但立即關閉。我把href＃但它不工作。

如果我檢查生成的HTML是：

<a id="ctl00_ctl38_g_69332c4e_2a87_4bb4_ad70_f7debbd14e91_LnkButton" onclick="OpenModalPopup('www.google.com', '800', '300');" href="javascript:__doPostBack('ctl00$ctl38$g_69332c4e_2a87_4bb4_ad70_f7debbd14e91$LnkButton','')">

ASCX或web部件文件

<script type="text/javascript"> 
    function OpenModalPopup(pageUrl, widthParameter, heightParameter) { 
     var options = { url: pageUrl, width: widthParameter, height: heightParameter, showClose: true }; 
     SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options); 
    } 
</script> 
<asp:LinkButton CssClass="pwcLinkButton" ID="LnkButton" runat="server" href="#"></asp:LinkButton>

的.cs

更改您的代碼，看看是否它幫助：

LnkButton.Attributes.Add("onclick", "OpenModalPopup('" + Link.ToString() + "', '" + WidthPopup.ToString() + "', '" + HeightPopup.ToString() + "'); return false;");

看來，它不是你的彈出窗口關閉，但你的鏈接導致回發，所以頁面刷新。如果您的鏈接onclick處理函數返回false，它將被瀏覽器解釋爲取消鏈接clic，因此不會導致回發。所以改變這一行爲：

LnkButton.Attributes.Add("onclick", "OpenModalPopup('" + Link.ToString() + "', '" + WidthPopup.ToString() + "', '" + HeightPopup.ToString() + "'); return false;");

應該做的伎倆。
