Possible to detect whether an IFRAME is loaded in the Navigating event?


Possible to detect whether an IFRAME is loaded in the Navigating event?

With these it helps Found out a workaround:
I had to implement the additional DWebBrowserEvents2 interface as described in this Code Project article to get additional events.
code :
public class BrowserExtendedNavigatingEventArgs : CancelEventArgs
{
    // ...

    public bool IsInsideFrame
    {
        get
        {
            var wb = AutomationObject as UnsafeNativeMethods.IWebBrowser2;
            return wb != null && wb.Parent != null;
        }
    }

    // ...
}
public void BeforeNavigate2(
    object pDisp,
    ref object url,
    ref object flags,
    ref object targetFrameName,
    ref object postData,
    ref object headers,
    ref bool cancel)
{
    // ...

    var isTopFrame = _browser._axIWebBrowser2.Equals(pDisp);

    // ...
}

I wish this helpful for you I am trying to check whether an iframe has loaded after the user clicks a button. , You may try this (using jQuery)
code :
$(function(){
    $('#MainPopupIframe').load(function(){
        $(this).show();
        console.log('iframe loaded successfully')
    });
        
    $('#click').on('click', function(){
        $('#MainPopupIframe').attr('src', 'https://heera.it');    
    });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id='click'>click me</button>

<iframe style="display:none" id='MainPopupIframe' src='' /></iframe>
window.onload=function(){
    var ifr=document.getElementById('MainPopupIframe');
    ifr.onload=function(){
        this.style.display='block';
        console.log('laod the iframe')
    };
    var btn=document.getElementById('click');    
    btn.onclick=function(){
        ifr.src='https://heera.it';    
    };
};
<button id='click'>click me</button>

<iframe style="display:none" id='MainPopupIframe' src='' /></iframe>
$(function(){
    $('#click').on('click', function(){
        var ifr=$('<iframe/>', {
            id:'MainPopupIframe',
            src:'https://heera.it',
            style:'display:none;width:320px;height:400px',
            load:function(){
                $(this).show();
                alert('iframe loaded !');
            }
        });
        $('body').append(ifr);    
    });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id='click'>click me</button><br />

I hope this helps you . I didn't find the information about this topic in google. Can I detect if my (Rails) application is being loaded from iframe? If yes, can I obtain the url of the iframe? I'd like to do it by both javascript and on the server if it's not possible, if not - whatever way is easier. , through javascript its very easy.
code :
function isInIframe () {
    try {
        return window.self !== window.top;
    } catch (e) {
        return true;
    }
}
$_SERVER['HTTP_REFERER'] but this is not foolproof.

wish helps you You can reference the outer iframe with this inside the load event handler, which makes it a bit tidier. This should do what you need...
code :
document.querySelector("#iframe1").addEventListener("load", function() {
    this.contentDocument.querySelector("iframe").style.width = "100%";
});

may help you . The plan is not to have a scroll bar to the iframe that I am adding to my page. So the idea to do it as I thought is to have a onscroll function. , JQuery solution:
