asp.net – HTML divs可以在浏览器窗口之外？

我正在玩ASP.NET Web部件,它有一个“下拉”div.它一直到页面右侧.当我点击它时,它会离开窗户.通常,可视区域外的任何内容都会触发底部滚动条.这怎么可能？

编辑：它是Internet Explorer 8.下面是带有一些上下文的标记.我认为相关的一个是id = WebPart_wp774658725VerbsMenu.默认情况下,它不显示.当你点击td / span Verbs / span VerbsPopup(它可能是任何)时,它会显示“下拉列表”.在开发人员工具中,我没有看到任何JavaScript附加到这些元素,但如果我调试它,我看到它运行一些.

<TD class=partTitle>

WebParts.js
    function WebPartMenu_OnClick() {
    var a = window.event.srcElement.__menu;
    if (typeof a != "undefined" && a != null) {
        cancelEvent(window.event);
        a.Show()
    }
}

function WebPartMenu_Show() {
    if (typeof __wpm.menu != "undefined" && __wpm.menu != null) __wpm.menu.Hide();
    var e = "<html><head><style>" + "a.menuItem,a.menuItem:Link { display: block; padding: 1px; text-decoration: none; " + this.itemStyle + " }" + "a.menuItem:Hover { " + this.itemHoverStyle + " }" + '</style><body scroll="no" style="border: none; margin: 0; padding: 0;" ondragstart="window.event.returnValue=false;" onclick="popup.hide()">' + this.menuElement.innerHTML + "<body></html>",b = 16,c = 16;
    this.popup = window.createPopup();
    __wpm.menu = this;
    var d = this.popup.document;
    d.write(e);
    this.popup.show(0,b,c);
    var a = d.body;
    b = a.scrollWidth;
    c = a.scrollHeight;
    if (b < this.menuLabelElement.offsetWidth) b = this.menuLabelElement.offsetWidth + 16;
    if (this.menuElement.innerHTML.indexOf("progid:DXImageTransform.Microsoft.Shadow") != -1) a.style.paddingRight = "4px";
    a.__wpm = __wpm;
    a.__wpmDeleteWarning = __wpmDeleteWarning;
    a.__wpmCloseProviderWarning = __wpmCloseProviderWarning;
    a.popup = this.popup;
    this.popup.hide();
    this.popup.show(0,this.menuLabelElement.offsetHeight,c,this.menuLabelElement)
}

解决方法

确实是createPopup方法可以解决问题.它是Internet Explorer中的专有方法.
