我正在尝试使用 JavaScript 打开一个 ModalPopup，我已经在 stackoverflow 上进行了搜索，一般建议似乎是使用这样的东西：
$('#inputAdd').live("click", function () {
$('#addRow').show();
$find('<%=mpeIndications.BehaviorID %>').show();
});
#inputAdd 是我在 ModalPopup 中的 html 输入图像，它的目标是显示显示 TextBox 的行（#addRow）。但是，当我单击#inputAdd 按钮时，它显示该行，但随后 ModalPopup 隐藏，我认为原因可能是因为有一个包含 ModalPopup 的 UpdatePanel，我是对的吗？在那种情况下，这可能是一个解决方案？我已经将一些代码放在了.ascx 中。谢谢。
