那位大哥帮我看看这段代码,我调用showModelessDialog 打开一个网页对话框,怎么一弹出就自动关闭了,小弟只有12分了,现加上10(10分)

StringBuilder ScriptString = new StringBuilder();
ScriptString.Append(&quot;<script language=javascript>&quot;
ScriptString.Append(&quot;function ShowTest()&quot;
ScriptString.Append(&quot;{&quot;
ScriptString.Append(&quot;
window.showModelessDialog('test.aspx', window, 'dialogHeight: 575px;
dialogWidth: 465px;
edge: Raised;
center: Yes;
help: No;
resizable: No;status:Yes;scroll: No;' );&quot;

ScriptString.Append(&quot;}&quot;
ScriptString.Append(&quot;</script>&quot;
String js = ScriptString.ToString();
if (!IsClientScriptBlockRegistered(&quot;ShowTest&quot)
{
RegisterClientScriptBlock(&quot;ShowTest()&quot;, js);
}
LinkButton1.Attributes.Add(&quot;OnClick&quot;, &quot;ShowTest()&quot;
网页对话框网弹出就关闭了

会不会是被拦截弹出窗口的插件干掉了？
