Javascript 调整iframe的大小以加载内容

我想在iframe中加载内容，并根据内容调整其高度。所有页面都在同一个域中。我尝试了一些我找到的脚本，但没有任何效果。大多数情况下，它只是在新选项卡中打开加载的内容

HTML:

您可以尝试在加载iframe后获取高度，并使用jquery对其进行更改

     $('iframe').load(function() {
        setTimeout(iResize, 50);
        // Safari and Opera need a kick-start.
        var iSource = document.getElementById('your-iframe-id').src;
        document.getElementById('your-iframe-id').src = '';
        document.getElementById('your-iframe-id').src = iSource;
     });
     function iResize() {
        document.getElementById('your-iframe-id').style.height = 
        document.getElementById('your-iframe-id').contentWindow.document.body.offsetHeight + 'px';
     }

你可以试试看这个：@Stefan，我试过删除newwidth行，但它会将内容加载到一个新选项卡中。

div#container {
    height: 100%;
    width: 100%;
}
div#header {
    top: 0px;
    width: 100%;
    height: 80px;
    position: fixed;
    background-color: transparent;
    text-align: center;
}
div#nav {
    font-family: MgSouvenirLight;
    font-size: 18pt;
    color: #FF0;
    top: 120px;
    width: 100%;
    height: 40px;
    position: fixed;
    text-decoration: none;
    font-weight: bolder;
    font-variant: normal;
}
div#footer {
    font-family: Arial, Helvetica, sans-serif;
    font-size: 9px;
    bottom: 0px;
    position: fixed;
    height: 30px;
    width: 100%;
    text-align: center;
    color: #fff;
 }
#frame {
    position: absolute;
    top: 200px;
    bottom: 40px;
    width: 800px;
    border: none;
    left: 120px;
    height: auto;
}
a:link {
    font-family: MgSouvenirLight;
    font-size: 18pt;
    color: #FF0;
}
a:visited {
    font-family: MgSouvenirLight;
    font-size: 18pt;
    color: #FF0;
}
a:hover {
    font-family: MgSouvenirLight;
    font-size: 18pt;
    font-style: italic;
    color: #FC0;
}

     $('iframe').load(function() {
        setTimeout(iResize, 50);
        // Safari and Opera need a kick-start.
        var iSource = document.getElementById('your-iframe-id').src;
        document.getElementById('your-iframe-id').src = '';
        document.getElementById('your-iframe-id').src = iSource;
     });
     function iResize() {
        document.getElementById('your-iframe-id').style.height = 
        document.getElementById('your-iframe-id').contentWindow.document.body.offsetHeight + 'px';
     }
