我正在创建一个带有链接按钮的可视 web 部件,链接按钮应该打开一个模式弹出窗口。
我已经定义了函数,但我不确定如何使链接按钮触发 javascript 函数。
请参阅 CreateChildControls 方法
<asp:Content ID="Content1" ContentPlaceHolderId="PlaceHolderAdditionalPageHead" runat="server">
<script type="text/javascript">
function dialogfunction(pageUrl) {
var options = { url: pageUrl, width: 900, height: 300 };
SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options);
}
</script>
</asp:Content>
<asp:LinkButton ID="LnkButton" runat="server"></asp:LinkButton>
