ngSrc duplicate request for iframe in IE

[Ilya-Hubich]

Hi.

I have the issue with iframe and ngSrc directive in IE 10 in Standard mode.
When I set the ngSrc value it duplicate request for iframe resources.
One of them is with status 'aborted' and another is '200 OK'.

But sometimes on the server side we get 2 requests instead of 1.
It's critical for us because one of params(guid) should be unique, but when two same requests are sent the guids are the same too.

The jsfiddle exampe is here : http://jsfiddle.net/6au10sk4/4/

In angular source code i find :

Line:15704

      attr.$set(name, value);
      // on IE, if "ng:src" directive declaration is used and "src" attribute doesn't exist
      // then calling element.setAttribute('src', 'foo') doesn't do anything, so we need
      // to set the property as well to achieve the desired effect.
      // we use attr[attrName] value since $set can sanitize the url.
      if (msie && propName) element.prop(propName, attr[name]);
    });

I think here is the problem :

      if (msie && propName) element.prop(propName, attr[name]);

Which version are you using? Did it happen after upgrading? Does it only happen in IE10?

[Ilya-Hubich]

I am using 1.2.16 version. I didn't do any upgrades.
IE 10 and IE 11 reproduce this bug.
Other IE versions i didn't try.

Locally I fixed this issue in this way:

if (msie && propName && element[0].tagName !== 'IFRAME') element.prop(propName, attr[name]);

But our soft works in different environments. And we install dependencies from bower...

You can use a directive decorator to overwrite the ngSrc directive in your app's config block (see e.g. http://angular-tips.com/blog/2013/09/experiment-decorating-directives/). That way you are independent from bower. You still have to check for changes to the directive when you update, but it's better then nothing.

[Ilya-Hubich]

As I see in example you provided, decorating directives is good for expand standard functionality.
That's why we decided to create our own directive for iframes.

Thanks a lot for help.

Let's reopen this, as it is not fixed.
