How can I get the image src?

I'm using a WebView2 on Windows Forms. I want to get that image src from html and show it in a MessageBox

<div class="col-sm-6" style="z-index:900;padding:0">
<img id="imageCodeDisplayId" width="180" height="50" ng-src="mysite.com/wp-content/uploads/img.jpg" alt="Verify Image" style="padding:2px;border-style:solid;border-width:1px;border-color:#CCC;margin-top:5px;margin-bottom:5px" src="mysite.com/wp-content/uploads/img.jpg">
<a class="glyphicon glyphicon-repeat" aria-hidden="true" title="Reload" style="cursor:pointer;font-size:30px;top:10px;left:10px;text-decoration:none" ng-click="getCaptcha()"></a>
</div>

Solution

  • You can use document.getElementById('imageCodeDisplayId').src to access the src attribute of the img element.

    You can use the ExecutScriptAsync() method to retrieve the value via C#.

    Here you go:

    // get the src attribute value
string srcAttributeValue = await webView21.CoreWebView2.ExecuteScriptAsync("document.getElementById('imageCodeDisplayId').src");

// show it in a message box
MessageBox.Show(srcAttributeValue);
