Twitter Widget Fails to Load Any alternative to Test if the Tweet id in widget is invalid?

[vtankaria]

I have a widget created : Tweets by @vtankaria

It loads tweets in iframe properly.

Also if i change the href in same widget having same data-widget-id say to : Tweets by @ladygaga

It loads tweets in iframe properly.

But If the herf is of invalid user say : https://twitter.com/wealkaldk

Tweets by @wealkaldk

I loads the iframe with blank Body .

I want to avoid this blank iframe from loading . How shall I test If the user has a valid tweet Id before loading its widget ??? Else I can show No Tweets Instead rather then showing blank iframe

The URL the link points to has no effect on whether the timeline is going to be loaded properly or not.
To change the user displayed you have to use data-screen-name as described there: https://dev.twitter.com/docs/embedded-timelines#timeline-selection
