我需要帮助才能使这两个<div>(#side-nav和#content-wrapper)独立滚动,

HTML:

<div id="wrapper">
    <div id="top-nav">
        Top nav
    </div>
    <div id="side-nav">
        <ul>
            <li>Thing</li>
            <li>Thing</li>
        </ul>
    </div>
    <div id="content-wrapper">
        <!-- Ton of conent here -->
    </div>
</div>

CSS:

#wrapper {
  width: 100%;
  background-color: #fff;
}

#top-nav {
  position: fixed;
  top: 0;
  height: 60px;
  width: 100%;
  background-color: green;
}

#side-nav {
  position: fixed;
  width: 250px;
  height:100vh;
  overflow-y: scroll;
  background-color: red;
}

#content-wrapper {
  margin: 60px 0 0 250px;
  padding: 0 30px;
  overflow-y: scroll;
  background-color: blue;
} …

我希望我的treepanel在双击时做一些事情.

但是,当我双击treenode时,节点总是消耗或折叠.

当我双击时,如何禁用此扩展或折叠.

我的英语不是很好抱歉!

我正在尝试使用QWebview在打印机上打印图像文件,但不打印图像空白页.请找到以下代码.

void ChartViewer::onprintBtnClicked()
{
    QString fileName = QFileDialog::getOpenFileName(this,"Open File",QString(),"Pdf File(*.png)");
    qDebug()<<"Print file name is "<<fileName;
    if(fileName.endsWith(".png"))
    {
        QPrinter printer;
        QWebView *view = new QWebView;
        QPrintDialog *dlg = new QPrintDialog(&printer,this);
        printer.setOutputFileName(fileName);
        if(dlg->exec() != QDialog::Accepted)
            return;
        view->load(fileName);
        view->print(&printer);
    }
}

如果我使用view-> show(),那么它已正确显示图像,但打印页面空白.请你查看上面的代码并纠正我在哪里做错了.

我正在使用swfupload插件.当我尝试上传图像时,我想传递两个参数,但参数未被传递.

                 var id1='g';
                var opt1='g';
       function getValues()
                {
                    id1 = $("#id").val();
                    opt1=$("#opt").val();
                    return id1.concat(opt1);
                }

             $(document).ready(function(){

             alert(getValues()); // Here coming
